A new study suggests that some women are just more vulnerable to some of the rarer types of early breast cancer. Ductal carcinoma in situ, or DCIS, in particular, affects young black women, although it can be found in almost anyone.
According to researchers, epidemiology studies have shown that the annual removal of 50,000 to 60,000 DCIS lesions did not show a reduction in the cases of invasive breast cancers, in comparison to the experience in removing colonic polyps and intraepithelial neoplasia lesions in the cervix which has shown a decrease in cases of colon and cervical cancer, respectively. It is also now known that breast cancer surrounds a wide range of behaviors, from aggression to indolent. Indolent behavior is more likely to surface during screening, which can be an obstacle in diagnosis. The finds have led to concerns regarding a change in strategy for the detection and treatment of DCIS.
They further stated that there may be a lack of clear distinction between DCIS and invasive cancers, likely due to overdiagnosis, as the incidence of DCIS has increased over the same period. Dr. Barry Kramer, the director of the cancer prevention division in the U.S. National Cancer Institute, has expressed his agreement that a lot of women are being over-treated with DCIS.
