Many patients ask me if their cancer is genetic. I tell them all cancer is genetic, but few are hereditary.
Confused? Let me explain.
Every cell in the body contains a blueprint for the entire person. And that blueprint, which defines how our bodies look and function, is called our genetic code.
Each of our blueprints is a blend of our mom’s and our dad’s genes. If mom or dad or both gave you a blueprint with a defect or mutation in a gene, then we call it hereditary. But if the original blueprint was fine, but became damaged over time, we call it an acquired mutation.
So years of tobacco use, eating unhealthy foods, or getting too much sun damages genes causing acquired mutations that result in cancer.
So all cancer is genetic, but only 10% hereditary.
How we treat the cancer is next week’s topic.
