Genetic forms of cancer are rare. Having a family member with cancer does not necessarily mean that you are at risk for a genetic form of cancer.
You may be at risk for a genetic form of cancer if:
- Several people in your family have the same type or types of cancer
- Some people in your family have been diagnosed with cancer at a young age
- Some people in your family have had more than one type of cancer
The most common genetic forms of cancer are breast, colorectal and ovarian cancer, but other types of cancer can be genetic too.
