.....Radiation damage takes a long time to heal and often doesn't show up for a couple of years.....I take a I drink plenty of liquids and eat more veggies.
I had another colonoscopy last week, almost two years after radiation. My radiation proctitis is just now clearing up, but it has been no picnic. According to my GI, the damage to my colon is still visible, but thankfully the life altering symptoms have subsided.
For those considering radiation, insist your oncologists discuss short and long term radiation dangers in detail. Most, in my experience, don't volunteer it willingly. No different than many urologists who push surgery. Caveat Emptor!
