Cancer is notoriously famous as the curse that passes down generations, affecting direct blood descendants of cancer patients with the same ferocity. How true is this? Let’s find out – is cancer hereditary, or not.
Cancer as we know it today can be broadly categorised as ‘Sporadic’ or ‘Hereditary’. Before we begin breaking down the inheritance of cancer, we need a basic understanding of how cancer is developed in the first place.
“Cancer” is a genetic mutation. All known cancers are caused by changes to the genes in our bodies. When genes get damaged, their changes are termed ‘mutations’.
Consistent mutation can cause these affected cells to grow out of control and cause cancer.
Cancer is not a result of a single genetic mutation; it takes more than one mutation to develop a tumour. It takes more than one gene mutation for cancer to occur. For people with no history of cancer who end up developing cancer, such mutations happen over the course of a lifetime, leading to cancer in later life.
Some people (people with a family history of cancer) are born with a gene mutation that they inherited from their mother/father. This damaged gene creates higher cancer risk, as compared to regular people (people who don’t have a family history of cancer).
When a tumor develops as a result of a hereditary gene mutation, it is called ‘Hereditary Cancer’s. Only about 5% to 10% of all cancers are thought to result directly from gene defects (called mutations) inherited from a parent.

Sporadic (non-hereditary) Cancers and Hereditary Cancers are different in many aspects that eventually decide the prognosis of each patient and what treatment/procedure is more effective in each case:
For families that have had a history of the same type of cancer, the disease is strongly linked to an inherited gene mutation. This inherited gene mutation is a part of a family cancer syndrome.
The following factors hint towards the existence of a Family Cancer Syndrome. Stay on alert for Family Cancer Syndrome:
Genetic Testing refers to the use of medical tests to identify specific mutations in a person’s genes. There are many genetic tests in use today, and more in development. Out of these, Predictive Genetic Testing is the type of testing that can be used to identify family members who are at higher risk of developing cancer from an inherited gene mutation.
Such tests are advised to patients when:
