Genetic analysis and advice

About 5-10% of all cancers are hereditary, meaning that mutations of certain genes are passed from a blood relative to another. People who inherit one of the abnormal genes are much more likely to develop cancer during their life and at an earlier age.

The common cancers that are associated with a family history are:

  • Breast cancer
  • Colorectal Cancer
  • Ovarian cancer
  • Prostate cancer
  • Endocrine cancer

Radiant Oncology recommends that people with a family history of these cancers talk to their doctor about how to monitor and control their increased risk of cancer.
