Breast awareness

Inherited Risk

Hereditary or inherited breast cancer can develop because of a gene mutation (alteration) that has been passed down from a parent.

It’s less common than most people think – only 5-10% of all breast cancers are hereditary. Around 8 out of 10 women who get breast cancer don’t have any family history of the disease. Most breast cancers are sporadic, which means they occurred by chance or due to factors other than an inherited mutation.

Should you be referred?
