Q: I am 31 years old and my daughter is 3+. I recently attended a seminar on breast cancer and came to know that if the size of both the breasts vary, then it can be a sign of cancer. My mother passed away some 35 years back after giving me birth due to breast cancer. She was 32 when she died. My left breast became larger than the left one after I fed my daughter for a year. There is no abnormality or swelling or lump in my breast. Is this a cause of worry?

A:There is no reason for you to worry. Minor size variations are normal. You should look for any lump in the breast or bloody discharge from the nipple. You should get a mammogram done.
