In some cases, DCIS may become invasive and spread to other tissues, but there is no way of determining which lesions will remain stable without treatment, and which will go on to become invasive. There are 2 main types of in-situ carcinoma of the breast: ductal carcinoma in-situ (DCIS) and lobular carcinoma in situ (LCIS).

Accessed April 27, 2018. The pathologist looks at slides of the DCIS under the microscope to see how close the DCIS cells get to the ink (the edges or margins of the specimen). The risk of recurrence depends on both patient charac- teristics, such as family history of breast cancer in a first degree relative and younger age at diagnosis, as well as on tumor. Your doctor should discuss this with you. Mayo Clinic does not endorse companies or products. Most of the women who develop DCIS do not experience any symptoms. 103(6):478-88, 2011. Whenever possible, surgeons will try to cut tissue outside of the tumour to reduce the risk that any cancer cells will be left behind after the tumour is removed. Long-term outcomes of breast-conserving therapy for women with ductal carcinoma in situ. Ductal carcinoma in situ (DCIS) makes up a majority of noninvasive breast cancer cases. They have not started to spread into the surrounding breast tissue. [23] More definitive diagnosis is made by breast biopsy for histopathology. Donker M, Litière S, Werutsky G, et al. [14] Clinically, it is considered a premalignant (i.e. Some of these are linked to a higher chance that the DCIS may come back after treatment, so finding them may change your treatment. [1] [2] O CDIS é classificado como estágio 0. Early detection is important because DCIS sometimes progresses to an invasive form of breast cancer if left untreated. Paget disease of the nipple is usually associated with DCIS or invasive carcinoma (cancer) in the underlying breast tissue. El carcinoma ductal invasivo (CDI) es la forma más común de cáncer de mama. RESUMEN Objetivo: Este estudio evaluó las características del carcinoma ductal in situ (CDIS), incluyendo grado citológico, patrón arquitectural y inmunohistoquímica en CDIS puro y asociado a carcinoma invasivo tipo no especial (CI-TNE).. Métodos: Evaluamos una serie de 232 casos de CDIS puro o asociado a carcinoma mamario invasivo procedentes de una población de mujeres diagnosticadas . The genetic mutations cause the cells to appear abnormal, but the cells don't yet have the ability to break out of the breast duct. El interés de la RM en el estudio preoperatorio del CDIS todavía es incierto. 30(12):1268-73, 2012. With the right information, patients can make the best decisions about their care. It needs to be treated but is not life-threatening. Sort by: Most popular. Although whole breast radiation therapy after lumpectomy doesn’t impact survival, it lowers the risk of [5-12]: Some women with DCIS may have the option of partial breast radiation therapy or skipping radiation therapy altogether [5]. If untreated, DCIS progresses to invasive cancer in roughly one-third of cases, usually in the same breast and quadrant as the earlier DCIS. 28(5):662-669, 2015. [25] Surgical removal, with or without additional radiation therapy or tamoxifen, is the recommended treatment for DCIS by the National Cancer Institute. Percent positive with something saying whether the staining is weak, moderate, or strong. What is the COMET study? Additional tests may be used to determine whether the cancer is estrogen-receptor positive or negative—important information that helps the medical team predict whether the cancer may be treated with hormone therapy. Ductal carcinoma in situ (DCIS) now represents 20-25% of all 'breast cancers' consequent upon detection by population-based breast cancer screening programmes. On needle biopsy, measurements of the area of DCIS are not often reported because this type of biopsy only samples a part of the tumor. Anastrozole versus tamoxifen for the prevention of locoregional and contralateral breast cancer in postmenopausal women with locally excised ductal carcinoma in situ (IBIS-II DCIS): a double-blind, randomised controlled trial. We welcome Thomas Mulliez and Mark De Ridder's comments on the BIG 3-07/TROG 07.01 study.1 The 15% increase in acute adverse events in patients who had a tumour bed boost compared with no boost after whole breast irradiation for ductal carcinoma in situ was mainly due to self-limiting radiation dermatitis.

The distance is usually described in millimetres. March 4, 2022. ​If you received treatment (either chemotherapy or radiation therapy) for your cancer prior to the tumour being removed, your pathologist will examine all of the tissue submitted to see how much of the tumour is still alive (viable). These cells are all contained inside the ducts. Hormone therapy can lower the risk of [5,9,14-18]: These risks are lowered in both the treated breast and the opposite breast. [29], While surgery reduces the risk of subsequent cancer, many people never develop cancer even without treatment and the associated side effects. [22] Nonetheless, the risk of developing noninvasive cancer increases with age and it is higher in women older than 45 years. Because ductal carcinoma in situ is a non-invasive type of cancer. Make an appointment with your doctor if you notice a change in your breasts, such as a lump, an area of puckered or otherwise unusual skin, a thickened region under the skin, or nipple discharge. This means some people are over-treated for DCIS. [4] [5]O CDIS corresponde à presença de células anormais no revestimento . If left untreated, patients with DCIS are at high risk for developing a more serious disease called invasive ductal carcinoma. Your pathologist will perform a test called immunohistochemistry to see if the tumour cells make ER or PR. Overall survival is the same for women with DCIS who have lumpectomy (with or without radiation therapy) and those who have mastectomy [5]. Currently, all DCIS lesions . A clinical trial studying active monitoring as an alternative to surgery may be another option. These risks are higher with lumpectomy plus radiation therapy than with mastectomy [2]. En la histología: carcinoma ductal in situ de grado intermedio. 12(1):21-9, 2011. [7] DCIS encompasses a wide spectrum of diseases ranging from low-grade lesions that are not life-threatening to high-grade (i.e. 26(13):4317–4325, 2019. Diferenciación entre CLIS y afectación lobulillar por CDIS (Tabla 1). View resources and events in your local community. DCIS starts in the tubes (ducts) of the breast that carry milk. Without treatment, DCIS cells could progress to invasive cancer over time. [4] [5] It has been diagnosed in a significant percentage of men (see male breast cancer). Learn about DCIS, its symptoms, risk factors, diagnosis, grading and treatment. DCIS is usually found during a mammogram done as part of breast cancer screening or to investigate a breast lump. Researchers don't know exactly what triggers the abnormal cell growth that leads to DCIS. There are 2 main types of in-situ carcinoma of the breast: ductal carcinoma in-situ (DCIS) and lobular carcinoma in situ (LCIS). Tumours that make ER or PR are treated with special medication that targets the activity of these proteins. Learn more about radiation therapy for DCIS. There are three types of lymph nodes that may be described in your report: If cancer cells are found in a lymph node, the size of the area involved by cancer will be measured and described in your report as follows: Finding cancer cells in a lymph node is associated with an increased risk that cancer will come back at a distant body site such as the lungs in the future. The treatment effect will be reported as follows: Lymph nodes are small immune organs located throughout the body. En los tumores de grado 1, las células tumorales y la organización del tejido del tumor tienen una apariencia cercana a la normal. Accessed April 27, 2018.

Book an appointment today! [1][2] DCIS is classified as Stage 0. [10][11] It is the most common type of pre-cancer in women. A negative margin means there were no cancer cells at the very edge of the cut tissue. [3]Raramente produz sintomas ou nódulos que se possam sentir durante a palpação, sendo geralmente detectado através de mamografia. Abstract. There are 2 main types of in-situ carcinoma of the breast: ductal carcinoma in-situ (DCIS) and lobular carcinoma in situ (LCIS). If there’s little spread of DCIS within the breast, a choice can be made between lumpectomy and mastectomy. DCIS does not spread outside these tubes. Your pathologist will examine the tissue submitted and give each part a number. No residual tumour – All the cancer cells are dead. [41] Biomarkers can identify which women who were initially diagnosed with DCIS are at high or low risk of subsequent invasive cancer. At this stage, the cells have not broken through the walls of the milk ducts into the surrounding breast tissue. Diseases of the Breast, 5th edition. No obstante, tres semanas después de la mastectomía bilateral, la paciente continuó con el tratamiento adyuvante del bloqueo dual HER2 con trastuzumab (600 mg) y pertuzumab (420 mg). PhyllisH Member Posts: 1. . This means the risk of the cancer spreading to lymph nodes and to other parts of the body is much lower. Howlader N, Noone AM, Krapcho M, et al. [36] However, research indicates that sentinel node biopsy has risks that outweigh the benefits for most women with DCIS. It’s stage 0 breast cancer. DCIS is noninvasive breast cancer. [10][11] It is the most common type of pre-cancer in women. Epidemiology. A diagnosis of DCIS means that abnormal cells have been found within the milk ducts of the breast. This lesion, which accounts for 75% of breast cancers, has no specific histologic characteristics other than invasion through the basement membrane of a breast duct, as seen in the image below. The tissue sample is examined under a microscope by a pathologist, who looks for the presence of cancer cells. Most cases of DCIS are found following routine screening with mammograms. Nearly all women with this early stage of breast cancer can be cured. If the entire tumor or area of DCIS is removed (such as in an excisional biopsy or breast-conserving surgery), the pathologist will say how big the DCIS is by measuring how long it is across (in greatest dimension), either by looking at it under the microscope or by gross examination (just looking at it with the naked eye) of the tissue taken out at surgery. Histopathology of the cribriform type of breast ductal carcinoma in situ. Ductal carcinoma in situ (DCIS) is a neoplastic proliferation of mammary ductal epithelial cells confined to the ductal-lobular system without evidence of invasion through the basement membrane into the surrounding stroma (Arch Pathol Lab Med 2009;133:15) Is a nonobligate precursor lesion of invasive breast cancer (Breast Cancer Res Treat 2010;123:757, Cancer 2005;103:2481) Radiation therapy is rarely given to women treated with mastectomy for DCIS. All rights reserved. [13] Tamoxifen may be used as hormonal therapy if the cells show estrogen receptor positivity. Purpose To identify uptake and determinants of surveillance imaging in women who underwent treatment for DCIS. Carcinoma ductal in situ. Adjuvant tamoxifen reduces subsequent breast cancer in women with estrogen receptor-positive ductal carcinoma in situ: a study based on NSABP protocol B-24. Often, the first instinct is to act quickly. AskMayoExpert. About 1 in 5 new breast cancers will be ductal carcinoma in situ . Intraductal carcinoma is another name for ductal carcinoma in-situ. When your breast was biopsied, the samples taken were studied under the microscope by a specialized doctor with many years of training called a pathologist. Stout NK, Cronin AM, Uno H, et al. El 87 % grado nuclear II o III actividad mitótica 82 % fue baja o moderada sólo 4 % alta. If DCIS is touching the ink (called positive margins), it can mean that some DCIS cells were left behind, and more surgery or other treatments may be needed. Ductal carcinoma in situ (DCIS) is a non-invasive breast cancer. All of these are terms for benign (non-cancerous changes) that the pathologist might see under the microscope. In DCIS, abnormal cells are found in the lining of one or more milk ducts in the breast. Download. DCIS is a non-invasive breast cancer, but it may progress to invasive breast cancer over time. Because this tissue is rarely sent, the metastatic stage cannot be determined and is listed as pMX. It is not cancer and may not become malignant. [30] While the authors caution that longer follow-up will be required before a definitive conclusion can be reached regarding long-term toxicity, they point out that ongoing technical improvements should further restrict radiation exposure in healthy tissues. Effect of tamoxifen and radiotherapy in women with locally excised ductal carcinoma in situ: long-term results from the UK/ANZ DCIS trial. Ductal carcinoma in situ is given a metastatic stage of 0 or 1 based on the presence of cancer cells at a distant site in the body (for example the lungs). If this happens, the cancer is known as invasive . El grado bajo se refiere a una situación en . Visser LL, Groen EJ, van Leeuwen FE, Lips EH, Schmidt MK, Wesseling J. Predictors of an invasive breast cancer recurrence after DCIS: a systematic review and meta-analyses. Because ductal carcinoma in situ is a non-invasive type of cancer. Small tubes (ducts) conduct the milk to a reservoir that lies just beneath your nipple. Stuart KE, Houssami N, Taylor R, Hayen A, Boyages J. DCIS is considered the earliest form of breast cancer. Results for ER and PR are reported separately and can be reported in different ways: Ask your doctor how these results will affect your treatment. This information is also used to determine the nodal stage (see Pathologic stage below). If all the margins are negative, most pathology reports will say how far the closest cancer cells were to a margin. 11:CD000563, 2013. 24(10):2889-2897, 2017. Lymph nodes aren’t usually removed. "Ductal" means "related to the milk ducts". Guideline adherence has not been characterized in a contemporary cohort. Is DCIS cancer? Ductal carcinoma in situ (DCIS) is considered the earliest form of breast cancer. Treatment may include breast-conserving surgery combined with radiation or surgery to remove all of the breast tissue. DCIS that is intermediate grade, is nuclear grade 2, or has an intermediate mitotic rate falls in between these two. Cuzick J, Sestak I, Pinder SE, et al. Sanders ME, Schuyler PA, Simpson JF, Page DL, Dupont WD. 31(32):4054-9, 2013.

DCIS is a neoplastic proliferation of epithelial cells within the ductal structure of the breast. E-cadherin is a test that the pathologist might use to help determine if the carcinoma in situ is ductal or lobular. Es un tipo muy temprano de cáncer de seno no invasivo. summary of research studies on tamoxifen in the treatment of DCIS. With the increasing use of screening mammography, noninvasive cancers are more frequently diagnosed and now constitute 15% to 20% of all breast cancers. Lippincott Williams and Wilkins, 2014. [3] It rarely produces symptoms or a breast lump one can feel, typically being detected through screening mammography. Hormone therapy: Also called endocrine therapy, this approach uses medication to treat types of cancer that are dependent on hormones for their growth. [9] DCIS can be detected on mammograms by examining tiny specks of calcium known as microcalcifications. Information in this report will be used to help manage your care. Ductal carcinoma in situ (DCIS), also known as intraductal carcinoma, is a pre-cancerous or non-invasive cancerous lesion of the breast. DCIS with microinvasion, defined as focus of invasive cancer measuring up to 1.0 mm in size. Women who are treated with lumpectomy for hormone receptor-positive DCIS may take a hormone therapy pill (tamoxifen or an aromatase inhibitor) [5]. Sometimes, the tissue removed during a biopsy or breast surgery shows both DCIS and invasive breast cancer. Not all DCIS will progress to invasive breast cancer, but doctors can’t tell which DCIS will progress and which won’t. We’ve invested more than $5 billion in cancer research since 1946, all to find more – and better – treatments, uncover factors that may cause cancer, and improve cancer patients’ quality of life.

Sometimes, a sentinel node biopsy, which removes 1-5 lymph nodes in the underarm area, is done at the same time as a mastectomy for DCIS. After surgery and radiation therapy, some people take hormone therapy [5]. LCIS is discussed on a€different page.5 Sometimes DCIS and LCIS are both found in the same biopsy. Fort Washington, Pa.: National Comprehensive Cancer Network. [40] About 2% of women who are diagnosed with this condition and treated died within 10 years. [27] There is no evidence comparing surgery with watchful waiting and some feel watchful waiting may be a reasonable option in certain cases. However, in a small number of patients, some symptoms may occur, including: Any noticeable changes to a breast should be discussed with a doctor. There is some disagreement on its status as a cancer; some bodies include DCIS when calculating breast cancer statistics, while others do not. [38][39], With treatment, the prognosis is excellent, with greater than 97% long-term survival. Comedonecrosis is a special type of necrosis sometimes seen in DCIS. DCIS has been classified according to the architectural pattern of the cells (solid, cribriform, papillary, and micropapillary), tumor grade (high, intermediate, and low grade), the presence or absence of comedo histology,[8] or the cell type forming the lesion in the case of the apocrine cell-based in situ carcinoma, apocrine ductal carcinoma in situ. These women have an excellent prognosis with a very low risk of DCIS recurrence or developing breast cancer in the opposite breast. 103(9):1778-1784, 2005. [35], Cases of DCIS have increased five-fold between 1983 and 2003 in the United States due to the introduction of screening mammography. DCIS (ductal carcinoma in situ) is non-invasive breast cancer that starts in the milk ducts. DCIS is one of the most common types of breast cancer - according to national records, 1 in every five new breast cancer cases is a DCIS. Similar to ductal carcinoma in situ, lobular carcinoma in situ begins—and remains—in the cells that line the breast lobules (the glands that make milk). [4][5] It has been diagnosed in a significant percentage of men (see male breast cancer). In contrast, grade 3 (high grade) DCIS is made up of cells that have large, hyperchromatic (dark), and very irregularly shaped nuclei and mitotic figures are usually easy to find. Philadelphia, Pa.: Churchill Livingstone Elsevier; 2014. https://www.clinicalkey.com. "In situ" means "in place". This page was updated on October 18, 2022. 1-877 GO KOMEN In this setting, cancerous means that there is an abnormal increase in the growth of the epithelial cells, which accumulate within and greatly expand the ducts and lobules ( Figure 1 ). The metastatic stage can only be . Molecular tests may help predict the chances of DCIS coming back (recurring) in the breast, but not all cases need these tests. J Clin Oncol. As long as the carcinoma cells are still confined to the breast ducts or lobules, and do not break out and grow into surrounding tissue, it is considered in-situ carcinoma (also known as carcinoma in situ, or CIS). 1-877-465-6636 (Se habla español) Therefore, it is important to slow down and take the time to learn about DCIS and your treatment options. Since suspicious groups of microcalcifications can appear even in the absence of DCIS, a biopsy may be necessary for diagnosis. [28] Chemotherapy is not needed for DCIS since the disease is noninvasive. Some cases of DCIS are considered over-treated because they will never progress to invasive breast cancer. Lancet. In the context of "overdiagnosis" the low grade DCIS cases found on screening mammography are likely to cause the number of cases where the diagnosis of breast malignancy has been made but could conceivably not have been fatal to the patient . Incidence. Diseases of the breast. [30] The addition of radiation therapy to lumpectomy appears to reduce the risk of local recurrence to approximately 12%, of which approximately half will be DCIS and half will be invasive breast cancer; the risk of recurrence is 1% for women undergoing mastectomy. BCS involves only removing the tumor and some of the surrounding tissue, while a mastectomy removes the entire breast, especially when the DCIS tumor is large. Seis factores están relacionados con el desarrollo final de cáncer de mama invasivo después de un diagnóstico inicial de carcinoma ductal in situ, trastorno a menudo benigno, de acuerdo con un nuevo metanálisis neerlandés.

Invasive ductal carcinoma is the most commonly diagnosed breast cancer and has a tendency to metastasize via lymphatics. These are all different ways of describing how the DCIS looks under the microscope: Patients with higher grade DCIS may need additional treatment. The growth potential of DCIS varies based on three grades: A DCIS diagnosis may also include information on the cancer’s hormone-receptor status. Carcinoma ductal in situ: conceptos actuales . It's stage 0 breast cancer. This is a long story but I will try to shorten it. 1-877 GO KOMEN [3] It rarely produces symptoms or a breast lump one can feel, typically being detected through screening mammography. DCIS is called non-invasive because, after careful microscopic examination, cancer cells were found only on the inside of the ducts and glands. a carcinoma ductal in situ de alto grado. However, if cancer cells are found in one or more lymph nodes your pathologist will provide a nodal stage between 0 and 3 based on the number of lymph nodes that contain cancer cells, the number of cancer cells found in the lymph node, and the location of the lymph nodes with cancer cells. The impact of surgery, radiation, and systemic treatment on outcomes in patients with ductal carcinoma in situ. Cancer Epidemiol Biomarkers Prev. About 20–30% of those who do not receive treatment develop breast cancer. Sometimes, though, the surgeon has already removed more tissue (at surgery) to help make sure that this isn’t needed. Testing for ER is done for most cases of DCIS, but testing for PR is not typically needed. They get little benefit from treatment, beyond peace of mind. [34] Mastectomy, however, may decrease the rate of the DCIS or invasive cancer occurring in the same location. We don’t think that all DCIS would go on to become invasive cancer, but we can’t tell which DCIS would be safe to leave untreated. DCIS cannot usually be felt as a breast lump or other breast change. [13][17] When classified as a cancer, it is referred to as a non-invasive or pre-invasive form. Use multiple keywords separated by spaces (e.g. This type of cancer stays in the area it first began (in situ). Ductal carcinoma in situ (DCIS), also known as intraductal carcinoma, is a pre-cancerous or non-invasive cancerous lesion of the breast. Ductal carcinoma in situ (DCIS) is a non-invasive type of breast cancer. potentially malignant) condition,[15] because the biologically abnormal cells have not yet crossed the basement membrane to invade the surrounding tissue. Ductal carcinoma in situ (DCIS) is a nonobligate precursor of invasive cancer, and its detection, diagnosis, and management are controversial. Comedonecrosis is more likely to be seen in high-grade ductal carcinoma in situ. [4][5] It has been diagnosed in a significant percentage of men (see male breast cancer).[6]. Long-term use of estrogen-progestin hormone replacement therapy (HRT) for more than five years after menopause, genetic mutations (BRCA1 or BRCA2 genes), atypical hyperplasia, as well as radiation exposure or exposure to certain chemicals may also contribute in the development of the condition. Cancer Statistics Review, 1975-2017. Whether you or someone you love has cancer, knowing what to expect can help you cope. In comedonecrosis, the dead cells are in the centre of a duct and surrounded by living cells. Menu. If Paget disease is found on needle or punch biopsy, more tissue in that area usually needs to be removed with the goal of entirely removing the area of Paget disease. The question of how and when a case of DCIS will extend beyond the ducts to become invasive breast cancer has implications for both patient prognosis and optimal treatment approaches. Staley H, McCallum I, Bruce J. Postoperative tamoxifen for ductal carcinoma in situ. Title: Ductal Carcinoma In Situ. This series of Frequently Asked Questions (FAQs) was developed by the Association of Directors of Anatomic and Surgical Pathology to help patients and their families better understand what their pathology report means. DCIS is considered the earliest form of breast cancer. An excision biopsy is much like a type of breast-conserving surgery called a lumpectomy. It's in situ, which means it does not spread to other healthy tissues from its point of origin. helpline@komen.org, Donor Services Support: Become a volunteer, make a tax-deductible donation, or participate in a fundraising event to help us save lives. Never ignore professional medical advice in seeking treatment because of something you have read on the MyPathologyReport site. Breast anatomy. [4][5] It has been diagnosed in a significant percentage of men (see male breast cancer).[6]. Accessed on June 26, 2020. The location you tried did not return a result. In-situ carcinoma with duct and lobular features means that the in-situ carcinoma looks like DCIS in some ways and LCIS in some ways (when looked at under the microscope), and so the pathologist can’t call it one or the other. Therefore, it is considered stage 0 breast cancer. Niederhuber JE, et al., eds. El 78 % presentó necrosis. Cochrane Database Syst Rev. Outcome of patients with ductal carcinoma in situ untreated after diagnostic biopsy: results from the Nurses’ Health Study. For example, the report may say that DCIS was found in 3 slides. J Natl Cancer Inst. List Your Practice ; Search . Because ductal carcinoma in situ is a non-invasive form of cancer and is always given the tumour stage pTis. Most groups recommend considering routine breast cancer screening beginning in your 40s. In an invasive carcinoma, the tumor cells can spread (metastasize) to other parts of your body. Este un cancer de san neinvaziv sau preinvaziv. Talk with your doctor about what's right for you. A single copy of these materials may be reprinted for noncommercial personal use only.

Your pathologist will carefully examine all the margins in your tissue sample to see how close the cancer cells are to the edge of the cut tissue. Nearly all breast cancers are carcinomas. DCIS cannot spread to the lymph nodes or other parts of the body. Estos tumores tienden a crecer y a diseminarse lentamente. Breast Cancer Res Treat. In situ means "in place" and refers to the fact that the abnormal cells have not moved out of the mammary duct and into any of the surrounding tissues in the breast ("pre-cancerous" refers to the fact that it has not yet become an invasive cancer). 2010(41):162-77, 2010. [14][16] When multiple lesions (known as "foci" of DCIS) are present in different quadrants of the breast, this is referred to as "multicentric" disease. The articles on MyPathologyReport are intended for general informational purposes only and they do not address individual circumstances. It’s most commonly used in patients who’ve had a lumpectomy, since this treatment lowers the chances that the cancer will return. With DCIS, the abnormal cells haven’t broken through the walls of the milk ducts and haven’t spread to nearby breast tissue. About 15 percent of breast cancers in the U.S. are DCIS [1]. Breast Cancer; Atlanta, GA: American Cancer Society, 2019. Then, when the biopsy is done, the pathologist looks at the tissue removed to be sure that it contains calcifications. After discussing the benefits and risks with your doctor, we encourage you to join a clinical trial if there’s one right for you. Allred DC, Anderson SJ, Paik S, et al.

Partridge Committed to Guiding Komen’s Research Strategy, Christina’s Story: Breast Cancer Survivor Two Times, DCIS recurrence (a return of DCIS) in the treated breast, Invasive breast cancer in the treated breast, Small, low grade DCIS (the DCIS cells look similar to normal cells), Clean surgical margins (the area of tissue surrounding the DCIS removed during surgery contains no DCIS cells). This term is used for the earliest stage of breast cancer, when it is confined to the layer of cells where it began. DCIS often appears as small flecks of calcium (called microcalcifications) on a mammogram or ultrasound. Also, women who have never had children or had them late in life are also more likely to get this condition.
