I lost my mother to cancer when I was 10. How can I check myself, or what do I need to see? I also have two daughters, and I am worried.

I start the daughter of a woman who's had breast cancer with screening mammography 10 years earlier than her mother's age at diagnosis. So if your mother was 40, you should start screening at age 30. Screening should include a mammogram and a clinical breast exam and ultrasound if it is needed. Regarding your daughters, they should begin having clinical breast exams at age 18-20, when they start going to a gynecologist, and they should start learning how to do breast self-exams at about the same time.
