I'm undergoing radiation therapy for prostate cancer right now, 5 days a week. When I learned of it through a PSA blood test and a subsequent biopsy, I wasted no time finding the best doctor with the best equipment that I could. He's rated among the 10 best doctors in Florida, and a renowned radiation oncologist in the US.
When my life is on the line I don't mess around with poorly-proven approaches, theories and philosophies, instead of hard science with a demonstratable track record of success. And when I had narrowed my selection down to this guy, imagine my genuine surprise when my partner recognized the name as the same doctor who had cured his own prostate cancer 7 years ago, before we got together.
And then I found out one of our best friends here was also successfully treated by this doctor 3 years ago, likewise for prostate cancer. This is what happens when you do your research. And BTW, 2 nights ago 5 of us went out to dinner, and 4 at the table have had cancer, with 3 cured and me pending but hopeful. So don't think this has no chance of touching you, because cancer is rampant today, especially of the prostate. And like Steve Jobs, 2 of the guys at dinner with me got cancer in their late 40s - early 50s. It's not just your grandparents' disease.
I have no idea what Steve Jobs did for his own cancer, if he tried alternative approaches, or immediately sought out the best experts in the world. Certainly he had infinitely more money than me, and all the resources & influence to be treated by whomever on Earth he wanted. Maybe he was genuinely incurable, no matter what.
But should this happen to you (and I advise regular doctor visits), I strongly recommend you take an aggressive, pro-active and mainstream approach. Consult with the finest doctors you can afford, and don't listen to advice from those who are not experts at all.
You will get an avalanche of advice from people who don't know shit, as I have. Do your research, select the best specialists who actually have credentials and results, and go with it.
