Cautherization???

Hi, I was at church yesterday and felt what I thought was urine running down my leg because of having the cathether removed and not being able to regulate it real good yet. I went to the restroom and was bleeding out of the rectum real bad. My bottom still hasn't healed from the surgery May 20th. They can't start chemo again until it does. I called my surgeon today and asked if he wanted me to wait until my appt on Wednesday to come in and he said no, to come in today. He said I am bleeding really bad and he could see where it was coming from, so he cautherized me. I think that's the right name for it. He said he kinda burned it and it should form scar tissue and heal. He said if I continue to bleed to call him back and he'll have to admit me to the hospital. Oh no, not again, I said. It's doing better. He wants to see me at my regular appt on Wednesday and he said he may need to cauterize me again. Does anyone know anything about this??? Am I saying the right term??? I hope this takes care of it. It should have healed a long time ago, but he said radiation has caused it not to. Any info would be appreciated.
Love and prayers, Judy(grandma047)
