when I was doing a lot psychedelics, I thought that I am close to discover cure for cancer, but I was afraid, that I will go insane completely ;p.
the truth about cancer is that it's mother nature's voice (something is wrong with you/your life style), and instant cure doesn't solve problems with it, because it depends of on healthy living..these are the reasons for cancer...However western consumptionic culture wants only instant cures to all illnesses and promote at the same way not always healthy life styles..so people are often paying what lifes they are living in....
Cancer is a very sad and painfull illness, and I feel sorry for all people touched with it/their friends&families..
