I have fibrocyctic breast beign cysts all my life can they turn into cancer? I get mammograms every year.

I have fibrocyctic breast beign cysts all my life can they turn into cancer? I get mammograms every year.

No: Fibrocystic change doesn't increase your risk. If you examine the breast closely, somewhere between 99% and 101% of women have these changes at some time. There are some other proliferative changes that put you at some extra risk, but what you're describing isn't worrisome. I hope you also do self-exam. Best wishes. ...Read more

2 cysts found in breast w/previous cancer.Ultrasound said benign .Should I seek further testing or 2nd opinion?

Talk to your doc: If they are well visualized simple cysts, the chance of malignancy is essentially zero. Asymptomatic simple cysts require no treatment. If they are "complex" cysts, meaning they have irregular or thick walls, septations, or other features making them suspicious, further evaluation may be necessary. So it depends what kind of cysts they are. If they were coded as "benign", they are prob simple ...Read more

Breast ultrasound showed 4 tiny cysts 3 with debri. Doctor said all is benign she sees no cancer . She made it a birad 3 extremely worried should I be?

Breast ultrasound showed 4 tiny cysts 3 with debri. Doctor said all is benign she sees no cancer . She made it a birad 3 extremely worried should I be?

Probably not. : Birads 3 means probably benign, for a 6 mo. Follow-up. One cyst with debris may be questionable. Multiple suggests a benign process. While this sounds most likely benign and nothing to worry about, if you continue to have concerns, ask your md to get a second opinion, or a follow-up ultrasound in 3 mos. Biopsy would not appear to be indicated at the present time. ...Read more

36 year-old woman whose mother was diagnosed with breast cancer at age 34 and a PALB2 mutation wonders if mastectomy is needed to lower her risk.....?

You need testing: If your mother was a BRCA carrier then it is important that you get tested. Since you know that she has a PLAB2 mutation then your testing can even be more precise. If you are a carrier then see an experienced breast surgeon.
