Cancer Societies have been shutting down cures for many years now. There are cures, there have been cures. But you are exactly right, they would not be profitable for the industry.
Instead they spend their (our) money on expensive treatments that cause cancers to return, and don't do anything about the cause.
Cancer societies and charities have done everything they can to make the public believe that the doctors who develop real cures are quacks and have even brought them down with ridiculous law suits.
Many Americans travel outside of the USA to get treatments that WORK but that have been outlawed because of the Cancer Societies greed.
It's scary and outrageous, but it's happening nonetheless!
