More on DCIS
The article’s subject is DCIS (Ductal Carcinoma in Situ). This non-invasive, “Stage O” malignancy of the breast has shot up in reported incidence over the past two decades. It’s one of the so-called slow-growing tumors detected by mammography; a woman can have DCIS without a mass or invasive breast cancer.
While some people with this diagnosis choose to have surgery, radiation or hormonal treatments, others opt for a watchful waiting strategy. The article quotes several physicians, including oncologists, who consider the surveillance approach favorably and otherwise.
In 2009 the NCI sponsored a conference on diagnosis and management of DCIS. The participants issued a helpful, albeit technical, consensus statement.
The bottom line is that optimal treatment for DCIS remains uncertain because doctors don’t yet know the natural course of this early-stage breast malignancy. The ClinicalTrials.gov website lists active and ongoing studies.
