Decades of Data Fail to Resolve Debate on Treating Tiny Breast Lesions
- More than 30 years after the widespread use of mammograms set off a surge in the detection of tiny lesions in milk ducts, there is still debate about how — or even whether — to treat them. In an era when there has been so much study of how to treat more advanced cancer, it might seem odd that there is so much uncertainty about these minute sprinklings of abnormal cells, often called Stage 0 cancer, which some say are not cancers at all.
- The latest round of controversy was set off by a paper published Thursday in JAMA Oncology that analyzed 20 years of data on 100,000 women who had the condition, which is also known as ductal carcinoma in situ, or D.C.I.S. The majority had lumpectomies (with or without radiation) and most of the others had mastectomies. The death rate from breast cancer of these patients, regardless of their choice of treatment, over the next 20 years was about the same as the lifetime risk in the general population of women, 3.3 percent.
