No. Cancer is not really hereditary in the true sense of the word. Hereditary means that you definitely get a trait such as eye colour or an illness from the genes you inherit from your parents. The cause of cancer is not as simple as that. Cancers are not caused by just one gene. Cancer is usually an illness of older people and most cancers occur when several genetic changes occur in a cell. This is called sporadic cancer. But some people inherit faulty (mutated) genes which make their chance of developing a particular cancer higher than normal.
Types of genes linked to cancer. Many of the genes that contribute to the development of cancer fall into broad categories: Tumor suppressor genes are protective genes. Normally, they limit cell growth by monitoring how quickly cells divide into new cells, repairing mismatched DNA, and controlling when a cell dies.ermline mutations in BRCA1 or BRCA2 genes increase a womanâs risk of developing hereditary breast or ovarian cancers. The most commonly mutated gene in people who have cancer is p53. In fact, more than 50% of all cancers involve a missing or damaged p53 gene. Most p53 gene mutations are acquired mutations.
