so I think you'll find your answer there. If you want to be cynical, prostate cancer and colo-rectal cancer each kill more people than Breast Cancer does now with the advances in treatment, or so I've heard. I have not researched this myself so I advance this argument tentatively.
I can't speak for any one but myself, and I don't know what the response of the women here will be, but I think your joke neither funny nor in good taste, considering the subject of Breast Cancer.
Prostate cancer needs a much greater priority because by the time they find it its usually too late, and the incidence of false positives on the blood test is high. Colo-rectal cancer can be caught and often treated with screening colonoscopy. It occurs most frequently in those with polyps, which are easily removed during the colonoscopy. So long as the neck of the polyp is benign and you are screened annually and all polyps removed quickly, it doesn't have to turn into cancer. My father, in the United States, despite having had a history of polyps was not checked until he had a tumor the size of a grapefruit in his lower abdomen. It was successfully removed along with his entire colon. He died before he left hospital possibly because of operative stress (he had a respiratory arrest during recovery after surgery), possibly because he was so depressed that he didn't want to live with a colostomy or ileostomy, whichever it was. He received limited instruction and education in hospital.
In Britain they have Stoma Nurses who see the patients from the day after surgery and then forever, visiting them in their homes to check on how they're coping and to give advice and support. The Home Visitor Stoma Nurse wasn't scheduled to see him until he'd been home for two weeks. He received little support and little education on stoma care and bag attachment and utilization except from my wife and myself, and while he brightened up for the duration of our visit and a couple of days afterwards, he then sank into depression again. Nobody intervened. I'm not happy about his treatment as you may have guessed, though I tried to get the Post Op people more involved.
