Are there different types of DCIS?

DCIS is divided into several subtypes, mainly according to the appearance of the tumor. These subtypes include micropapillary, papillary, solid, cribriform and comedo.

Is ductal carcinoma in situ really cancer?

Ductal carcinoma in situ (DCIS) is the presence of abnormal cells inside a milk duct in the breast. DCIS is considered the earliest form of breast cancer. DCIS is noninvasive, meaning it hasn’t spread out of the milk duct and has a low risk of becoming invasive.

How serious is ductal carcinoma in situ?

DCIS is considered non-invasive or pre-invasive breast cancer. DCIS can’t spread outside the breast, but it is often treated because if left alone, some DCIS cells can continue to undergo abnormal changes that cause it to become invasive breast cancer (which can spread).

What stage cancer is ductal carcinoma in situ?

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.

What is the best treatment for ductal carcinoma in situ?

Radiation therapy

Treatment of DCIS has a high likelihood of success, in most instances removing the tumor and preventing any recurrence. In most people, treatment options for DCIS include: Breast-conserving surgery (lumpectomy) and radiation therapy. Breast-removing surgery (mastectomy)

Can DCIS spread after biopsy?

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%.

How quickly does DCIS spread?

Grade 1 DCIS is almost always ER and PR positive and is a very slow growing form of cancer. It can take years, even decades, to see progression of the disease. In some cases, it may take such a long time to spread beyond the breast duct that it is not an event that will happen during a person’s lifetime.

What is the survival rate for ductal carcinoma in situ?

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.

What type breast cancer has the highest recurrence rate?

Research suggests that estrogen receptor-positive breast cancer is more likely to come back more than five years after diagnosis.

What is the survival rate for ductal carcinoma in situ?

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.

How long does it take for DCIS to become invasive?

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.

What percentage of breast cancer is DCIS?

Approximately 20 percent of breast cancers diagnosed in the United States (US) are DCIS, and over 60,000 women will be diagnosed in the US alone in 2015 [4].

Should I have a mastectomy 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. You have small breasts and a large area of DCIS or cancer. You have DCIS or cancer in more than one part of your breast.

How urgent is surgery for DCIS?

DCIS doesn’t need to be treated urgently, so you can take time to think things over. You should ask questions or discuss anything you don’t understand with your surgeon or breast care nurse. You may find our booklet Making treatment decisions useful.

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].

How many radiation treatments are needed for DCIS?

A typical course of radiation treatment for DCIS involves 16 sessions given over three weeks.

Is DCIS likely to return in other breasts?

Patients with DCIS have a 15% chance of invasive local recurrence, Dr. Narod noted, but “preventing the invasive local recurrence has nothing to do with preventing death.

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.
