Your individual cancer risk will be subject to a balance of nature vs. nurture.You cannot modify your genetics but you can decrease your risk through risk factor modification- healthy diet, exercise and screening for common tumors such colon cancer and breast cancer when applicable for your age. With the acid reflux, you are likely already being screened for Barrett's esophagus, a tumor prescursor

You can reduce your risk of cancer by adopting healthy habits: Eat a mostly vegetarian diet, avoid alcohol, tobacco and street drugs, avoid excessive exposure to sun, maintain healthy weight, get HPV vaccine, exercise 30 minutes each day, drink enough water so your urine is mostly colorless.
