Does all family history increase risk of breast cancer?
DEAR DR. ROACH: I am a 24-year-old woman. My mother had ductal carcinoma in situ in her mid- 40s, successfully treated with surgery and radiation. One of my paternal aunts survived a malignant breast cancer. Am I considered high risk for breast cancer? I know my mom’s cancer increases my risk, but does DCIS increase the risk level as much as a malignant cancer? When should I start undergoing mammograms or other screening? -- C.P.
