Fact 13: Genetics Play a Role
The role of genetics in our health narrative has always been a topic of intrigue. In the context of colorectal cancer, genetics doesn’t just play a cameo; it’s one of the lead actors. A significant percentage of colorectal cancers can trace their origins back to inherited gene mutations. These mutations, passed down through generations, can substantially heighten an individual’s risk, turning the typically random occurrence of cancer into a patterned familial legacy.
Two well-documented inherited syndromes, in particular, stand out in the context of colorectal cancer: Lynch syndrome (or hereditary non-polyposis colorectal cancer, HNPCC) and Familial Adenomatous Polyposis (FAP). Those carrying mutations linked with these syndromes aren’t just at a heightened risk; they often encounter the disease at a much younger age than the average population. With these mutations lurking in the backdrop, the onset of colorectal cancer can be accelerated, sometimes presenting itself even before the age of 50.
Given the weight genetics carries in this equation, family medical histories become invaluable. If there’s a recorded pattern of colorectal cancers or related conditions within a family, genetic counseling emerges as a recommended course of action. Such counseling sessions delve deep into familial medical narratives, offering insights, recommending specific screenings, and suggesting preventive measures tailored to an individual’s unique genetic profile.
The genetic discourse, it’s evident that our genes, the very blueprints of our existence, wield power in the realm of colorectal cancer. Recognizing, respecting, and responding to this genetic influence can pave the way for personalized medical trajectories, offering individuals a fighting chance against their inherited odds. (13)
