There are a lot of things women can do to minimize their vulnerability to breast cancer, but there is no certain prevention. If ever there were an instance to prove that, it is the recent breast cancer diagnosis given to Martina Navratilova. Surely no woman has taken better care of herself than Navratilova, but many factors come into play in the development of all cancers, not just breast cancer.
The good news is that Navratilova has been told that her prognosis is excellent. The type of cancer she has is DCIS (ductal carcinoma in situ), which is non-invasive. The breast lump was found in a routine mammogram, and a lumpectomy was performed in January. Navratilova will undergo six weeks of radiation therapy, beginning next month.
