Identify Risks for Future Generations Through Gene Testing if Cancer Exists in Family History

If any member of the family has suffered from cancer, members of the next generation need to be extremely cautious. Especially when parents, siblings, or other close relatives have developed certain types of cancer at a young age, ignoring this matter can prove costly. In such families, by testing the genes associated with cancer, the risks looming over the next generation can be identified in advance. This testing helps in starting timely screening and, in some cases, choosing options to reduce the risk of cancer.

According to a report by Amar Ujala, a study shows that in approximately 5 to 10 per cent of cancer cases worldwide, harmful gene mutations inherited from parents play a role. However, in most cancer cases, factors such as increasing age, tobacco consumption, environmental factors, diet, and changes occurring in cells during life are more significant.

If a mutation is found in the genes during testing, that risk can reach the children. Some gene mutations associated with cancer can be transferred from parents to children. BRCA 1-2 are such genes associated with breast and ovary cancer. If harmful changes are found in these genes, there is a 50 per cent possibility of them reaching the offspring. However, finding a gene mutation does not mean that cancer is certain, but it significantly increases the risk of the disease occurring.

According to Medical Oncology Consultant Dr. Pallavi Reddu, hereditary cases of cancer are relatively few. Therefore, if someone in the family has had cancer, instead of panicking, it is necessary to see what type of cancer it was and at what age it occurred. Types such as breast, ovary, pancreas, and prostate cancer may have a role of hereditary factors. If more than one close relative in the family, especially at a young age, has had these types of cancer, genetic counselling should be sought.

Dr. Reddu further stated that if such harmful mutations are found in gene testing, other members of the patient's blood relations should also be tested. This can identify people who need regular screening and medical supervision from a young age. Through this process, early symptoms of cancer can be identified and timely treatment can be started, which can prove decisive in saving lives.

Having a family history of cancer is not just a matter of concern, but it is a warning that the next generation should be more aware of their health check-ups. Gene testing done at the right time and guidance from experts help in reducing future risks.
