If your parent had breast cancer what are my chances of getting cancer?

Increased: The age that your parent developed breast cancer as well as the number of their relatives with cancer is important. In general, a younger age at diagnosis makes it more likely that you might develop breast cancer. In addition, if your mother and especially your father had breast cancer and tested positive for a brca gene mutation, you have a 50% risk of having that mutation, and should be tested.

Increased: Agree with dr. Attai. See if anyone else in family has had breast, ovarian, cervical, uterine, prostate, colon, gallbladder, pancreatic, transitional cell (ureter, some kidney), especially if multiple family members across generations, and/or if cancers were at early ages. Risk factors? Several studies show that alcohol intake (any type) can be an aggravating risk factor. U may want to limit it.

Increased: The risk solely from a 1st degree relative is about 2.5-4x's. The gail model is a validated calculator that was used for the largest prevention trials (p-1, p-2) and is available on the nci website which gives a 5 year and life time (through age 90) risk looking at various factors (age, menstrual history, findings on prior biopsies, and 1st degree relatives) and normals for comparison.
