Hereditary Cancer Testing: Understanding Genetic Risks for Early Prevention
Hereditary cancer testing has become a cornerstone of personalized medicine, allowing individuals to understand their genetic predisposition to certain cancers. Unlike sporadic cancers that develop due to random mutations or environmental factors, hereditary cancers are linked to inherited gene mutations passed down from parents. Through advanced DNA analysis, hereditary cancer testing helps identify mutations in genes such as BRCA1, BRCA2, MLH1, and APC, which are associated with higher risks of cancers like breast, ovarian, colorectal, and prostate cancer.
This testing process typically involves a simple blood or saliva sample, which is analyzed in specialized laboratories using next-generation sequencing (NGS) technology. The results provide detailed insights into a person’s genetic profile and potential cancer risks. Importantly, the results not only guide individuals but also their family members, as hereditary gene mutations can affect multiple generations. For those who test positive for a…
