When Is Cancer Hereditary? Genetic Testing Can Help Guide Targeted Prevention
Cancer diagnosed at an unusually young age, multiple cases of cancer within a family or certain specific diagnoses can all be important warning signs of an inherited cancer predisposition. In some cases, even a single diagnosis may be enough to warrant genetic testing. A genetic test result does not mean that someone will inevitably develop cancer. However, it can provide valuable information that enables personalised prevention, closer monitoring and, where necessary, more effective treatment.
