I just read the most interesting article about an unnoticed cure for cancer. It turns out, apparently, there's this medicine, unpatented, which also is cheap to produce can cure cancer. However, medical companies do not make profit from it, so they have it go unnoticed by.
While I'm not sure if this is true, it's always worth a shot to make people more aware or it.
