Genetic DNA testing helps in estimating the chance of developing cancer in your lifetime, and this is conducted by searching for specific changes in your genes, chromosomes, or proteins. These changes are called mutations. In addition to prenatal genetic testing for postnatal genetic testing, they can diagnose genetic inheritance and the risk of being affected.
Genetic testing has a vital role in hereditary risk assessment for breast cancer and is being used increasingly in the prevention, diagnosis, and treatment of breast cancer.
The best-known genes that can mutate and increase the risk of breast and ovarian cancer are BRCA1 and BRCA2. Women who inherit a mutation or abnormal change in one of these genes - their mother or father - have a much higher risk of developing breast cancer and breast cancer than the ovary.
Most people with breast cancer do not have a family history of the disease. However, if there is a significant family history of breast and ovarian cancer in the family, it may be reasonable to believe that a person has inherited an abnormal gene related to a higher risk of breast cancer. A genetic test consists of giving a blood or saliva sample that can be analyzed to detect any abnormality of these genes.
Genetic tests in India is recognized by many people widely and is available to identify some types of cancer including Breast cancer, ovarian cancer, Colon cancer, Thyroid cancer, Prostate cancer, pancreatic cancer, Kidney cancer, Stomach cancer.
No genetic DNA test can say if you will develop cancer for sure but can tell you that the results may be positive, negative or uncertain, and so doctor’s advice people to take a DNA test for cancer as a means to prevent, detect, treat or manage BRCA1 or BRCA2 diseases.
