New research has called a common treatment for early stage breast cancer into question. The treatment can often be disfiguring. According to a study published in the journal JAMA Oncology found that women with stage 0 breast cancer which is also known as ductal carcinoma in situ or DCIS who undergo treatment have the same likelihood of dying of breast cancer within 20 years as women in the general population. DCIS is often diagnosed after abnormal cells have been found in the breast's milk ducts. This is most often detected through a mammogram. It not makes up about one in five new breast cancer diagnoses according the American Cancer Society. The good thing is almost all women diagnosed at this stage can be cured.
