My husband has multiple myeloma, has plasmacytomas that were radiated prior to chemo and SCT. He had a very good result, no detection of active myeloma for a little under two years, is on Lena as maintenance treatment. His MProtein has now started to climb, doubling in the last two months. We have been reading up on diet and note a few articles on caffein and a potential influence on bone marrow, does anyone have any info on this? He is a moderate coffee drinker, about 2 cups a day. Thank you
