What Is Hereditary Cancer?
Hereditary cancer is a type of cancer that occurs due to changes, or mutations, in certain genes that are passed from parents to their children. These genetic mutations can significantly increase an individual’s risk of developing certain types of cancer.
Unlike sporadic cancers, which occur due to environmental factors or random mutations, hereditary cancers run in families.
Common Types of Hereditary Cancers
While not all cancers are hereditary, several types have a strong genetic link:
- Breast and Ovarian Cancer: Mutations in the BRCA1 and BRCA2 genes are well-known for increasing the risk of breast and ovarian cancer. Families with a history of these cancers should consider genetic testing.
- Colorectal Cancer: Hereditary nonpolyposis colorectal cancer (HNPCC), also known as Lynch syndrome, is a leading cause of inherited colon cancer. This condition also increases the risk for other cancers like endometrial cancer.
- Prostate Cancer: Certain genetic changes, particularly in the BRCA2 gene, can elevate the risk of prostate cancer.
- Pancreatic Cancer: Mutations in genes such as BRCA2 and others may increase the risk of developing pancreatic cancer.
- Melanoma (Skin Cancer): Familial atypical multiple mole melanoma syndromes (FAMMM) is an inherited condition that can heighten the risk of melanoma.
- Rare Hereditary Cancers: Some less common hereditary cancers include retinoblastoma and multiple endocrine neoplasia.

Genetic Testing for Hereditary Cancer
Genetic testing is crucial in identifying individuals at high risk for hereditary cancers. It involves analyzing DNA to find mutations associated with increased cancer risk. If you’re concerned about a family history of cancer, seeking advice from a Cancer Specialist in Kolhapur or visiting the Kolhapur Cancer Centre could be beneficial.
How to Assess Your Risk for Hereditary Cancer
Assessing your risk involves understanding your family’s health history. Key indicators of hereditary cancer risk include:
- Multiple family members with the same type of cancer
- Cancers occurring at an earlier age than usual
- Multiple types of cancer in a single family member
By consulting with healthcare professionals and possibly undergoing genetic testing, you can better understand your risk profile.
Preventive Measures for Individuals with High Genetic Risk
For those identified as high-risk, several preventive strategies can be employed. These may include more frequent screening, lifestyle changes, and in some cases, prophylactic surgeries to reduce risk.
For instance, individuals with BRCA mutations might consider preventive mastectomy or oophorectomy.
When to See a Genetic Counselor
If you believe you might be at risk for hereditary cancer, seeing a genetic counsellor can provide clarity. They can help interpret your family history and genetic test results, offering guidance on the next steps.
