Thank you for your post. I have to agree. Very little was said to me about long term side effects. I had two tumors. One was 7 1/2 inches in from the rectum the other 15 inches. I don’t know how much they took but he took some margins and limp nodes. Both cancer free. Thank God. Next appointment in 3 more months. Surgery took. More out of me than I thought. After reading several posts I have started taking benafiber. Is this something that should be considered in your opinion?
