EDTA chelation is effective if taken by injection. I have little faith in the oral pills. That particular product (ORACHEL) is something I believe was developed by someone else meaning the website is just a reseller.
EDTA is most effective at removing placque deposits from the circulatory system which makes heart problems improve. Since cancer is associated with heavy metal deposits (especially in fatty tissues such as breasts), EDTA is also effective at lowering the possibility of getting cancer for up to five years after going through a series of treatments. The Swiss did a study on this way back about 1980.

Good health requires a bunch of things working together syncronistically.
John Bryant of First Amendment Radio had the guy from this site:
