My husband has cancer which has spread. Doctor has said he will have immunotherapy, but amyloidosis has shown up in MRI brain scan. However, he is completely asymptomatic and is a fit and energetic man. Have been told that in a few rare cases, amyloidosis can worsen with immunotherapy. I feel that surely immunotherapy must have been given to thousands of people who have some degree of amyloidosis. Can this really prevent him from receiving immunotherapy? I've looked on the internet but can find no links. I wondered if you might know any more about it please? Thank you.
