Ductal carcinoma in situ (DCIS) means the cells that line the milk ducts of the breast have become cancer, but they have not spread into surrounding breast tissue. DCIS is considered non-invasive or pre-invasive breast cancer.

How serious is DCIS?

DCIS isn’t life-threatening, but having DCIS can increase the risk of developing an invasive breast cancer later on. When you have had DCIS, you are at higher risk for the cancer coming back or for developing a new breast cancer than a person who has never had breast cancer before.

What is the survival rate of DCIS?

Generally, patients diagnosed with DCIS have an excellent long-term breast-cancer-specific survival of around 98% after 10 years of follow-up24 27 and a normal life expectancy.

Is DCIS considered breast cancer?

DCIS is also called intraductal carcinoma or stage 0 breast cancer. DCIS is a non-invasive or pre-invasive breast cancer. This means the cells that line the ducts have changed to cancer cells but they have not spread through the walls of the ducts into the nearby breast tissue.

Do all breast cancers start as DCIS?

So DCIS can present in numerous different ways. About 20 percent of all breast cancer, 1 in 5 breast cancers will be a DCIS. And a majority of the time these are what are picked up on a mammogram because it’s the earliest signs of a breast cancer.

Should DCIS be removed?

Studies show that about 75% of DCIS cases may never become invasive breast cancer. Still, current guidelines for DCIS often recommend surgery, usually lumpectomy followed by radiation, to remove suspicious lesions.

Is DCIS grade 3 bad?

High Grade DCIS: May also be referred to as Nuclear Grade 3 or ‘high mitotic rate’. In this case, the cancer cells look more abnormal and tend to be fast-growing and more likely to recur after surgery.

Can DCIS be left untreated?

The cells in DCIS are cancer cells. If left untreated, they may spread out of the milk duct into the breast tissue. If this happens, DCIS has become invasive (or infiltrating) cancer, which in turn can spread to lymph nodes or to other parts of the body.

Is DCIS 100 curable?

But DCIS is nearly 100 percent curable. Typically, the treatment is a small operation called lumpectomy, often but not always followed by radiation to the area.

Is DCIS caused by stress?

Elevated levels of anxiety may cause women with ductal carcinoma in situ (DCIS), the most common form of non-invasive breast cancer, to overestimate their risk of recurrence or dying from breast cancer, suggests a study led by researchers at Dana-Farber Cancer Institute in Boston.

Does DCIS ever go away?

Clusters of abnormal cells like D.C.I.S.can sometimes disappear, stop growing or simply remain in place and never cause a problem. The suspicion is that the abnormal cells may be harmless and may not require treatment.

Will I survive DCIS?

Ten years after DCIS diagnosis, 98% to 99% of women will be alive. Based on this good prognosis, DCIS usually is treated by lumpectomy followed by radiation therapy. If the DCIS is large, a mastectomy may be recommended. Chemotherapy usually isn’t recommended following surgery for DCIS.

Is DCIS malignant or benign?

If these abnormal cells, which are uncontrollably growing, stay inside the duct, they are referred to as Ductal Carcinoma In-Situ (DCIS). They are ductal cells that have become malignant, but they have remained in their original place (in-situ) and are thus a noninvasive cancer.

Can DCIS lead to other cancers?

In some cases, DCIS may become invasive cancer and spread to other tissues. At this time, because of concerns that a small proportion of the lesions could become invasive, nearly all women diagnosed with DCIS currently receive some form of treatment.

Why did I get DCIS?

DCIS forms when genetic mutations occur in the DNA of breast duct cells. 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. Researchers don’t know exactly what triggers the abnormal cell growth that leads to DCIS.

Can DCIS be seen on mammogram?

DCIS is most often discovered during a mammogram used to screen for breast cancer. If your mammogram shows suspicious areas such as bright white specks (microcalcifications) that are in a cluster and have irregular shapes or sizes, your radiologist likely will recommend additional breast imaging.

Does having DCIS make you tired?

Conclusions: The prevalence of severe fatigue in DCIS patients was similar to BCS, but higher than in HC. Severely fatigued DCIS patients had a lower quality of life and more functional impairments. The psychosocial and behavioral fatigue-related factors in DCIS patients are known to perpetuate fatigue in BCS.

Can DCIS return after mastectomy?

Efficacy Mastectomy is curative for over 98 percent of patients with DCIS [15-19]. Disease recurrence is rare after mastectomy (1 to 2 percent) [3,20-22].

Is mastectomy needed for DCIS?

Although many cases of DCIS are treated with lumpectomy, your doctor might recommend mastectomy if the DCIS covers a large area or appears in multiple areas of the breast. In most DCIS cases requiring mastectomy, simple or total mastectomy (removal of breast tissue but no lymph nodes) is performed.

Is mastectomy an option for DCIS?

Most women with DCIS or breast cancer can choose to have breast-sparing surgery, usually followed by radiation therapy. Most women with DCIS or breast cancer can choose to have a mastectomy. A mastectomy may be a better choice for you if: You have small breasts and a large area of DCIS or cancer.

Does mastectomy cure DCIS?

Surgery is the first step to treat DCIS. It removes the abnormal tissue from the breast. Depending on how far the DCIS has spread within the milk ducts, surgery can be mastectomy or lumpectomy. If DCIS is spread throughout the ducts, affecting a large part of the breast, a total (simple) mastectomy will be done.

Is DCIS ever misdiagnosed?

IDC may be misdiagnosed as DCIS by preoperative biopsy. As mentioned above, 25.9% (18.637.2%) of cases preoperatively diagnosed as DCIS have been reported to be IDC according to a meta-analysis [5]. However, the ratio of misdiagnosis in this study was 40.7%, higher than that previously reported.

What is considered a large DCIS?

Large DCIS tumors (2.5 cm) pose a particular risk of residual disease regardless of margin status, and additional adjuvant therapy may be necessary.

Can DCIS spread after biopsy?

Because DCIS is not an invasive cancer and cannot spread to other parts of the body, whole body treatments, like chemotherapy, are not indicated for this stage of disease.

What are the chances of getting DCIS in the other breast?

After a DCIS diagnosis in one breast, the average risk of developing either DCIS or invasive breast cancer in the OPPOSITE breast is small — under 1% each year. The risk is higher for women who have an abnormal breast cancer gene (BRCA1 or BRCA2).

What is DCIS 3?

DCIS that is high grade, is nuclear grade 3, or has a high mitotic rate is more likely to come back (recur) after it is removed with surgery. DCIS that is low grade, is nuclear grade 1, or has a low mitotic rate is less likely to come back after surgery.

How fast does DCIS grow?

It assumes that all breast carcinomas begin as DCIS and take 9 years to go from a single cell to an invasive lesion for the slowest growing lesions, 6 years for intermediate growing DCIS lesions, and 3 years for fast-growing DCIS lesions.

How long can you wait for DCIS surgery?

The researchers assessed overall survival using five time intervals representing delays to surgery: less than 30 days, 31-60 days, 61-90 days, 91-120 days, or 121-365 days. Overall survival was 95.8 percent, with a median delay from diagnosis to surgery of 38 days.

Can DCIS be a mass?

As mentioned previously, in approximately 2%23% of cases, DCIS may manifest as a mass or asymmetry at mammography (2,3,5). Noncalcified DCIS may also be detected as a mammographically occult palpable lesion, cause for nipple discharge, abnormality at screening US, or finding in the evaluation of disease extent.

Does DCIS run in families?

There is also evidence from epidemiological studies that there is an inherited predisposition to DCIS. Women with DCIS have been shown to be 2.4 times (95 % CI 0.8, 7.2) more likely to have an affected mother and sister with breast cancer than controls [13].
