Innovations in technology are at the core of Silicon Valley, but this tech billionaire is pushing for the advancement of medical research this time.
"We've all been affected by cancer with someone in our lives," Sean Parker said Wednesday on CNBC's "Closing Bell." "Even though we've made some pretty good progress in treating about half of all cancers ... we haven't been as successful in bringing new therapies to market."
Immunotherapy, a treatment that uses parts of a person's immune system to combat diseases such as cancer, is the outlier to this battle, according Parker, former president of Facebook.
Parker announced a donation of $250 million for the research of immunotherapy for cancer treatments on Wednesday, an endeavor from his organization, The Parker Foundation. According to the American Cancer Society, immunotherapy is a very active area of cancer research.
