Unless proton beam therapy prevents this my Right paracaval lymph node will soon close off my superior vena cava (all blood flow to the heart). This lymph node has been growing at a rate of 3.84% per day for the 68 days between PET scans. 1.0384 ^ 90 = 29.7-fold increase every 90 days. The R2 cancer treatment that I just started takes 90 days to begin to take effect. -- Copyright 2024 Olcott "Talent hits a target no one else can hit; Genius hits a target no one else can see."
