I'm experiencing fibrocystic breast disease for years. i am now after menopause (age 77) is this a risk factor 4 breast cancer?

Yes and no: Yes in younger women we monitor those with this condition for a slightly higher risk of breast cancer. But as in your case, more than 90% of women will never develop this complication. At your age i would not worry about it other than have an annual clinical breast examination done by your family doc or gynecologist for any obvious lumps in your breasts. That is all you need to do.

NO: Fibrocystic changes can make it more difficult to examine breasts, and therefore may delay diagnosis in pre menopausal women, but as a rule there's minimal evidence to suggest that fibrocystic changes increases your risk of breast cancer. Just continue self breast exams, annual mammography, and physician exams yearly. Now, go and enjoy life. Good luck.
