Does fibrocystic breast diesease increase cancer risk?

No: Fibrocystic breast disease or mammary dysplasia is found in about 40% of women normally. It makes the breast tissue feel "lumpy" and is made worse with caffeine, and chocolate injestion especially near the end of a menstrual cycle. It is usually non-cancerous but can disguise an underlying breast tumor during breast examinations.

No: Fibrocystic breast disease is very common. Up to 50% of women have fibrocystic changes. About 1 in 8 women will develope breast cancer, which is quite a significant risk. Having fibrocystic breast changes does not increase the risk for breast cancer but makes it more difficult to detect. Mamograms are the best test for breast cancer and should be done once at age 35 and yearly after the age of 40.

Dense breasts: Fibrocystic is an old term, without correlation with anything of imortance, but dense breasts are a big deal. X-ray mammography relies on difference between normal fat, denser glands, and dense fibrous regions. Punctate calcifications signal risk, and changes warrant bopsies. Problem with dense breasts is these are harder to see, there is less fat. Leads to more ultrasound and MRI to see.

No.: Fibrocystic changes, in the truest sense, can only be diagnosed under the microscope after breast biopsy; the only changes associated with increased cancer risk are those with atypia. "fibrocystic disease" has become a catch-all term to describe "lumpy-bumpy" breast tissue, and is an almost-universal phenomenon in any woman who has been seen by a doctor for breast evaluation.

No: I agree with the others that there is no known association or risk of breast cancer with fibrocystic breast disease.
