Over 60,000 cases of Stage 0 breast cancer are diagnosed a year and all of them does not mean breast cancer, says American Cancer Society.

A data says over 60 percent of US woman population aged above 40 years underwent mammogram in past two years, and it has been found 20 percent of those were of Stage 0, which is called ductal carcinoma in situ (DCIS).

What is DCIS?

DCIS are cells that looks like invasive breast cancer cells inside the milk ducts, but those don’t spread further to breast tissue. However, doctors treat these abnormal cells by removing the masses (lumpectomy), lumpectomy and radiation together, or removing complete breast with mastectomy.

New Study of Stage 0 breast cancer

A new study published in the Journal of American Medical Association Oncology writes the ability to detect DCIS is leading to overtreatment of breast cancer.

More than 100,000 data of women diagnosed with DCIS were tracked and analyzed for 20 years. It was found those who were treated for DCIS and those who were not had similar chance of dying from breast cancer.

The study was conducted by Dr. Steven Narod from Women’s College Research Institute in Toronto. The database of all the women diagnosed for DCIS was part of the National Cancer Institute’s SEER program.

Chief medical officer of the American Cancer Society, Dr. Otis Brawley, said questions are now being raised whether there is an aggression in treatment of DCIS, and also the same is repeated in medicine too again and again.
