You might have gotten an email entitled "Cancer update email" or "Johns Hopkins update - very good article", which claims to be from an article sent out by the Johns Hopkins newsletter. The email gets stranger and stranger as you read it. Chemotherapy doesn't work to help cancer, it claims but changing your diet will do it. By the time you get down to the bottom which informs you that milk produces mucus which "feeds the cancer", you might be wondering about it.
This article of unknown origin never went out on Johns Hopkins newsletter according to Snopes and Hoaxslayer, the latter which suggests that especially with medical forwards, it's best to check them out before sending to friends.
Johns Hopkins, not real impressed (to put it mildly) about the email stating so many myths about cancer being attributed to them, dedicated a page on their website to deny and debunk the email, point by point.
To "Google" a forward, take the title and put it in quotes. In the case of this, since the title was more generalized, I also took a few key words like "cancer" and "alternate" and "Johns Hopkins" and added them to my search. With the search engines being so comprehensive and computers being so fast, it only takes a couple of seconds to check out a forward and it's really worth doing rather than sending out wrong information especially in the medical arena.
