What happens if DCIS is 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.Aug 5, 2013
Can DCIS spread after lumpectomy?
Will DCIS return or spread? Since DCIS is a noninvasive form of cancer, it does not spread throughout the body (metastasize). For patients having a lumpectomy with radiation, the risk of local recurrence ranges from 5% to 15%. For those having mastectomy, the risk of local recurrence is less than 2%.
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.Aug 26, 2015
How serious is DCIS?
DCIS is non-invasive because it hasn't spread beyond the milk ducts into other healthy tissue. DCIS isn't life-threatening, but if you're diagnosed with DCIS, you have a higher-than-average risk of developing invasive breast cancer later in life.Feb 4, 2022
What is a mammogram?
You may have a diagnostic mammogram, which takes views at higher magnification from more angles. This examination evaluates both breasts and takes a closer look at the microcalcifications to be able to determine whether they are a cause for concern.
Can you have a mastectomy with DCIS?
Most women with DCIS are candidates for lumpectomy. However, mastectomy may be recommended if: You have a large area of DCIS.
What is a calcification on a mammogram?
Calcifications are small calcium deposits in the breast that show up as white spots on a mammogram. Large, round or well-defined calcifications (shown left) are more likely to be noncancerous (benign). Tight clusters of tiny, irregularly shaped calcifications (shown right) may indicate cancer.
What is lumpectomy surgery?
A lumpectomy involves removing the cancer and some of the healthy tissue that surrounds it. This illustration shows one possible incision that can be used for this procedure, though your surgeon will determine the approach that's best for your particular situation.
What is radiation therapy after lumpectomy?
Radiation therapy after lumpectomy reduces the chance that DCIS will come back (recur) or that it will progress to invasive cancer.
What is clinical trial?
Clinical trials are studying new strategies for managing DCIS, such as close monitoring rather than surgery after diagnosis. Whether you're eligible to participate in a clinical trial depends on your specific situation. Talk with your doctor about your options.
How can we improve cancer care?
The report identified key ways to improve quality of care: 1 Ensure cancer patients understand their diagnoses so they can make informed treatment decisions with their health care providers 2 Develop a trained and coordinated workforce of cancer professionals 3 Focus on evidence-based care 4 Focus on quality measures 5 Provide accessible and affordable care for all
What is the National Comprehensive Cancer Network?
The National Comprehensive Cancer Network (NCCN) and the American Society of Clinical Oncology (ASCO) are respected organizations that regularly review and update their guidelines. In addition, the National Cancer Institute (NCI) provides treatment overviews.
How to treat 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 invasive or noninvasive?
DCIS is non-invasive, but without treatment, the abnormal cells could progress to invasive cancer over time. Left untreated, it’s estimated 20-50 percent of DCIS cases may progress to invasive breast cancer [ 1-5 ]. Health care providers cannot predict which cases of DCIS will progress to invasive breast cancer and which will not.
What is sentinel node biopsy?
A sentinel node biopsy is a procedure used to check whether or not invasive breast cancer has spread to the lymph nodes in the underarm area (axillary nodes). The surgeon removes 1-5 nodes.
Can axillary dissection cause lymphedema?
Because it disrupts more of the normal tissue in the underarm area, axillary dissection is more likely to affect arm function and cause lymphedema. So, even though a sentinel node biopsy may not be needed with DCIS, most people who have a mastectomy for DCIS will have a sentinel node biopsy done at the same time.
Can hormone therapy be used for DCIS?
Hormone therapy isn’t recommended for women who have a mastectomy for DCIS. These women have an excellent prognosis with a very low risk of DCIS recurrence or developing breast cancer in the opposite breast.

What is DCIS in mammography?
Before the advent of routine mammography, DCIS (ductal carcinoma in situ) was rarely detected. But today, DCIS accounts for 20% of breast cancer diagnoses and would be the fifth most common cancer in women if classified independently. Apar Gupta. Often called “stage zero breast cancer,” DCIS growths are confined to the inside ...
Does radiation help with survival?
It’s important to understand that radiation and hormone treatments do not change survival—the 10-year survival rate for women diagnosed with DCIS is 98% regardless of whether they receive either treatment. These treatments instead reduce the risk of breast cancer down the road. Since treatment of DCIS after surgery doesn’t improve survival, ...
What is stage zero breast cancer?
Apar Gupta. Often called “stage zero breast cancer,” DCIS growths are confined to the inside of the breast’s milk ducts, and many never develop into invasive cancers. Several treatment options are available, and opinions about the optimal treatment for DCIS vary widely among doctors.

What is the lowest risk of breast cancer?
The lowest risk of invasive breast cancer was in women who chose mastectomy. The risk of invasive breast cancer was seen regardless of severity of DCIS. Women who had low- or moderate-grade DCIS, as well as high-grade DCIS, had long-term increased risk. Women who are recently diagnosed with DCIS should work with their treatment team to weigh ...
Does DCIS increase the risk of breast cancer?
Overall, the researchers found that having DCIS more than doubled the risk of developing invasive breast cancer and increased the risk of dying of breast cancer by 70%, compared with the general population.
Does mastectomy reduce breast cancer?
A Danish study also found that women with DCIS who were treated with mastectomy had lower rates of invasive breast cancer in that breast than those treated with more conservative surgery, with or without radiation therapy.
