Is it possible cyst in the breast turn into breast cancer? What causes cyst in the breast? Is the breast cyst dangerous? Thank you

Depends. There are many types of cysts. Simple cysts rarely if ever are cancer. Complex cysts can be more dangerous. If you have a cyst, be sure to follow up with your doctor. They may want to do a needle aspiration and sample the fluid. Hope this helps!
Cysts form. when milk ducts become blocked, then fill with fluid and dilate. Simple cysts are benign and have no malignant potential.

Can fibrocystic breast disease lead to breast cancer?

Many have. Fibrocstic disease; few develop breast cancer. In addition to the genetic and familial risks, dense breasts are emerging as an independent risk, but this is confounded by the fact that it is difficult to image dense breasts with routine mammography, . Read more...
No, but... All women at some time have some of the changes we used to call "fibrocystic disease". Fibrosis and cysts pose no risk. If a woman has sclerosing adenosis or one of the atypical epithelial hyperplasias, her risk for a subsequent breast cancer is somewhat increased. I'd urge old-fashioned self-exam at the same time each month for all women, with biopsy of any dominant mass. Read more...

Will fibrocystic breast disease eventually or inevitably lead to breast cancer?

No. There is some evidence that "dense breasts" are at increased risk for developing breast cancer. Breast cancer may be less detectable in breasts with fibrocystic changes. However, the presence of fibrocystic change does not lead to breast cancer. Read more...
No. Women with fibrocystic breast disease will not "inevitably" have breast cancer, although fibrous breasts does make it more difficult to do self breast exams and may make it slightly more difficult to diagnosis breast cancer via mammograms.

No. Fibrocystic breast disease will not eventually become breast cancer. Besides the pain and discomfort associated with fibrocystic breasts, cancer screening imaging is not as effective in these denser breasts and so careful and regular examination is wise. Read more...
Its not a "disease" The term fibrocystic "disease" is outdated and inaccurate. Fibrocystic changes are very common (can be found in just about any women's breast tissue), are benign, and do not increase breast cancer risk. Increased breast density (a subjective mammographic finding) is associated with increased risk. Findings of atypia along with fibrocystic changes on a biopsy are also a marker of increased risk.

NO. Fibrocystic disease is now termed fibrocystic change and by itself is not associated with increased risk for breast cancer. However, regular breast self examinations and mammograms are still recommended. Read more...

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. Read more...

What to do if I have had fibrocystic breast disease for years. I am now after menopause (age 77) is this a risk factor 4 breast cancer?

It is not. If you had been given a diagnosis of atypical epithelial hyperplasia, sclerosing adenosis or one of its kin, your right might have been a bit higher. The question is really moot as hopefully you're doing self-exam and otherwise keeping up cancer surveillance. Best wishes. Read more...
