കാൻസർ പാരമ്പര്യമായി കിട്ടുന്ന ഒരു അസുഖമാണോ? Is cancer hereditary?
Certain types of cancer can be hereditary. Hereditary cancer refers to cancers that are caused by specific gene mutations that can be passed down from parents to their children. These mutations are present in the germline cells, which are the cells that give rise to eggs or sperm.
When a person inherits a gene mutation associated with hereditary cancer, it increases their risk of developing cancer compared to the general population. However, it does not guarantee that they will develop cancer. Other factors, such as environmental influences and lifestyle choices, can also play a role in the development of cancer.
Some well-known examples of hereditary cancer syndromes include:
Hereditary breast and ovarian cancer syndrome: This is associated with mutations in the BRCA1 and BRCA2 genes and increases the risk of breast, ovarian, and other cancers.
Lynch syndrome (hereditary non-polyposis colorectal cancer): This is caused by mutations in DNA mismatch repair genes and increases the risk of colorectal, endometrial, ovarian, and other cancers.
Familial adenomatous polyposis (FAP): This is caused by mutations in the APC gene and increases the risk of colorectal cancer and other types of tumors.
If someone has a family history of certain types of cancer or a known hereditary cancer syndrome, genetic counseling and testing may be recommended. Genetic testing can identify the presence of specific gene mutations associated with hereditary cancer, and genetic counselors can provide information and guidance on managing the risk and making informed decisions about preventive measures, such as increased surveillance or prophylactic surgeries.
It's important to remember that the majority of cancers are not hereditary and are instead caused by a combination of genetic and environmental factors. Regular screenings and maintaining a healthy lifestyle are crucial for early detection and prevention of all types of cancer, regardless of whether they are hereditary or not.
