My grand mother and my mother has breast cancer but both are well now..so how many chances are for me?

Higher risk: Self examine regularly breast feed your children mammograms biopsies of suspicious lesions.

Higher than average: Women with immediate family members who've had breast cancer have a higher risk than those who don't - that make sense. But, your chances are still only about 15%. And, like your relatives, the vast majority of women who get breast cancer survive, about 92%.So, you should not smoke, keep a good weight, and eat a lower fat diet. Do recommended surveillance. Self exams, etc. Good luck.

Genetic Counselor: You should speak with a genetic counselor. Genetic testing may be appropriate for you.
