After 2 Keytruda infusions added to my Alimta my CEA count has increased again, but seems to have slowed slightly, possible because I stopped CBD 2 weeks ago? New question: Keytruda and Prolia interaction? Anyone run across this issue? I’m due for my semi annual Prolia shot but see there may be interactions with Keytruda and steroids required by Keytruda. Oncologist referred me to Prolia prescribing GP and he’s referred me back to Oncologist!
