Olaparib-based medications

Olaparib is the first drug to exploit the "Achilles' heel" of cancers with BRCA mutations. Here is the logic: these cancer cells already have a broken DNA repair kit. Olaparib blocks their only remaining backup system (the PARP enzyme). The result is immediate: the cancer cell can no longer repair itself and dies. It is a precision weapon that turns the tumor's own genetic mutation against it, saving healthy cells while destroying ovarian, breast, and prostate cancers.
