My grandmother suffered for decades with hemmroids. Would not go to the doctor. She was an RN. Treated herself weekly with colonics.
She died of colon cancer in 1980. 74 years old. She should have known better. We all need more fiber in our diets, fresh fruits and vegetables.
Eat a balanced diet, limiting too much red meat. Eat yogurt with the natural cultures in it, and go in for that test if you have a family history earlier than 50.
"Eat a balanced diet"
A daily portion of food from the cabbage family is important as well. Eat your broccoli.
