Mayo Clinic Reports Dramatic Outcomes In Prostate Cancer Treatment
Zorglub writes "Two prostate cancer patients who had been told their condition was inoperable are now cancer-free as the result of an experimental therapy, the Mayo Clinic in Rochester announced Friday. 'Cancer has a propensity for turning off T cells. Dr. Allison hypothesized that if you block the off-switch, T cells will stay turned on and create a prolonged immune response. Dr. Kwon, then at NIH, demonstrated that CTLA-4 blockage could be used to treat aggressive forms of prostate cancer in mice. There was one limitation to that concept — the worry that by simply leaving all the T cells on there may not be enough response aimed at the tumor. Dr. Kwon called Dr. Allison and designed the trial together. The idea: use androgen ablation or hormone therapy to ignite an immune approach — a pilot light — and then, after a short interval of hormone therapy, introduce an anti-CTLA-4 antibody that acts like gasoline to this pilot light and overwhelms the cancer cells.' After the treatment, the patients' tumors shrunk to such a degree that they could be successfully removed."
So the immune system will actually fight cancer, but the cancer negates this by turning off the T-cells. This is fascinating. The problem, from what I understand, is that cancer cells reproduce indefinitely as their DNA does not slowly break down. It seems like this could be a real breakthrough for lots of cancer patients.

Know what else causes impotence?
Being dead from cancer.
True, it would be ideal to have a treatment that doesn't require any surgery, but if your choice is between impotence or death, I think most people will have the operation.
even if you quit smoking, you don't actually reduce your chances of getting lung cancer
Every source I've ever seen on this subject says that although ex-smokers have a higher chance of developing lung cancer than do lifelong nonsmokers, they're still less likely to develop lung cancer than are current smokers (of the same age and smoking history, of course.) If you have a citation to the contrary, please give it.
The correlation between ignorance of statistics and using "correlation is not causation" as an argument is close to 1.
How many men would choose between impotence and a, say, 1/1000 (no idea if that is the actual chance) of dying earlier?
You'd need to have the whole picture before you could make an educated choice.
I lost my father to prostate cancer a couple of years ago. When it got bad he wanted to die at home. We arranged that for him. I was with him during his last day. I watched him die.
I can tell you this. It's a life changing event watching someone die from cancer. Most people happily have no idea what it's like. I know though. Tumors up and down your spine, eyedroppers full of synthetic morphine to deal with the pain...it's absolutely unreal. Honestly.
Believe me, if it came down to it and someone told me today that they'd have to remove everything from my balls to my bellybutton to avoid that fate, I'd go to the table with a smile. I'd happily sit to pee if it meant I could dodge that bullet. Anyone would if they knew what I know.
Oh yeah, on an unrelated note - people who smoke are bat shit insane. They have absolutely no idea what's at the end of a losing roll of the dice.
