My father is 87, was in great health, until 2 months ago when he had a stroke,
he was recovering well, then this week they found stage 1 rectal cancer, 6 cm. from the anal passage. The Dr. has scheduled him for surgery this coming Wednesday,
to remove the cancer and an ileostomy. 12 years ago he had a double bypass and a valve replacement. How high risk is the surgery, I am very nervous and any thoughts or experience with this would be appreciated. Thank you.
