Tetanolic acid and Prostaganin are fiction... Why not Tit-o-nic acid then as a cure for breast cancer ! By the way, only a small percentage of breast cancers are caused by "deviant" stem-cells, no potential for billions in royalties here ! Next time, they'll come up with a novel antibiotic : SPOOK-O-MYCIN to treat CASINOVESTORS !!! Lol.
