There seems to be a lot of buzz around immunotherapy drugs (immune checkpoint inhibitors with brand names like Keytruda, Yervoy and Opdivo) as a gentler replacement / adjunct therapy to conventional cancer therapies. Do you have an opinion on these drugs? Are they still too risky or are they useful to investigate in addition to herbal protocols?
I ask because I am, in addition to herbs, researching immunotherapy cancer trials for my father-in-law who has stage 3 colorectal cancer.
Thank you,
