The only thing with polyps is that there is a chance they could be cancerous; but more often than not with women our age, is that they are benign growths that are bothersome. I had numerous ones and they were even going into the opening of one of my tubes this last time. My doctor said it's the estrogen that feeds them. In my case I've still got plenty of estrogen and am nowhere near menopause according to him. I did have a rather large one that was discovered from having hysterosalphogram (an ultrasound where saline is inserted for better pictures).
If I didn't have the polyps removed, not really sure what would happen except for more bleeding and worrying that they could be cancerous. Luckily, my doctor and I are in complete agreement with whatever he recommends and even though it's a pain having D&C's every few years, I'm glad it's done so I don't have to worry. It's pretty painless anyway, just a day of inconvenience is all.
Thanks for reminding me about the colonoscopy. I need to have that done this summer, too.
You're so right, it's great getting old!
