@linda90 , I am 13 years post radiation/chemo with metastatic SCC. Last metastasis was in 2020. I try daily to gain weight but no success. I am 15 lbs lighter than before the diagnosis. Keep exercising to maintain your strength and consume as much protein as you can for healing. I used a lot of yogurt, cottage cheese and half + half in smoothies to get more calories and protein. Just do your best and if you can maintain your weight that may be the best that you can do.
