Does DCIS shorten life expectancy?

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.

Does DCIS have the best prognosis?

Older Women Diagnosed With DCIS or Early-Stage Disease Have Excellent Prognosis. A large study found that women older than 67 diagnosed with either ductal carcinoma in situ (DCIS) or stage I breast cancer were just as likely to be alive 10 years after diagnosis as women not diagnosed with breast cancer.

What percentage of DCIS becomes cancer?

” DCIS rarely leads to death from breast cancer – approximately 11 out of 100 women treated by lumpectomy only go on to develop invasive cancer within eight years of the initial diagnosis of DCIS, and only 1 to 2 percent of women die of breast cancer within 10 years of diagnosis.

How long does it take for DCIS to turn into invasive cancer?

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 is risk after lumpectomy and no radiation for DCIS?

A study has found that for women diagnosed with DCIS considered to have a low risk of recurrence treated with lumpectomy without radiation, the risk of DCIS recurrence or developing invasive disease in the same breast increased through 12 years of follow-up and didn’t level off.

Does DCIS always come back?

The chance of the DCIS coming back depends on various factors. But after mastectomy DCIS almost never comes back. In women who have just the area of DCIS removed the chance of it coming back is a bit higher. But it depends on the grade and type of DCIS.

Is stage 0 really cancer?

For most cancers, stage 0 is called carcinoma in situ (CIS). “Stage 0 typically means that there are cancer cells that haven’t penetrated through the lining or the initial wall,” says David N. Oubre, MD, an oncologist and the founder of the Pontchartrain Cancer Center, which has two offices in Louisiana.
