Earliest detection of breast cancer poses treatment quandary

A new study is questioning the way the medical community typically defines and treats the earliest stage of breast cancer.

An analysis found that “ductal carcinoma in situ,” which typically shows up on mammograms, should be considered an early form of breast cancer, not just a precursor to cancer as it is frequently described, according to a paper published Thursday in The Journal of the American Medical Association Oncology.

The researchers, who analyzed existing data on more than 100,000 women treated for DCIS in the United States, found that women with DCIS are twice as likely to die from breast cancer compared to the general U.S. population.
