Look guys, I've seen lots of people die from cancer. Occupational hazard. Is there a doctor around who wishes we could do more? Every damn one of us.
But, you also have to remember that many people live through this, at increasing rates every year, because we do the research and find better ways. Without chemo (and I have been through it) they (and I) would have died. Is that a better option?
Should a patient ignore a doctor's advice to do chemo because it might help them and try eating herbs, spices, and doing shamanistic rituals instead? Really? If it was you in the office being told that you have a severe diagnosis but the chances of chemo working are 50%, wouldn't you try it instead of trusting that eating grass that's been organically grown will "save you"? I'll take the science every day. And so do millions, and millions live because of it. Sure, you hear about the odd "miracle", for who-knows-what reason. Do you think we quacks sit around wishing the miracle didn't happen and defied our knowledge of what was possible. Hell, we celebrate each life, no matter how the change happens.
Until you've been through it and had to make the decisions, you have no idea what it's like. But think it through: you have a critical diagnosis. Chemo or surgery gives you XX percent chance. Or you can try unproven techniques that have who-knows-what chance. Which will YOU take?
