I too was diagnosed with low grade follicular non Hodgkin lymphoma over 3 years ago November 2015 and was found by a fluke .I have 5 lessons mostly in my abdomen and 2 are quite large almost 5” but I am told they are slow growing low grade. Since my diagnostic I have had 6 PetScans and each one shows a growth of 1/4” but I am told that is slow growing. I have not had any treatment and am on the watch and wait since I have nosystems. My last PetScan showed no growth and it’s the first time in 3 years. My metibolic heat is lower than it’s been in 3 years too. My Oncologist says it could reverse. I am keeping my prayers going and fingers crossed. Has anyone else heard of this happening?
