Been a while since I have been on here. I had a lung resection on Valentines day and have had a long recovery. After removal of tumor it was later diagnosed with Stage 4 Squamous Cell Carcinoma located in my pleural cavity. I am treated every 21 days with infusion of Keytruda, an immunotherapy drug. I will have to have the rest of my life. I filed a new claim today for Cancer, Respiratory….Presumptive Agent Orange Condition. I have been SMC-S housebound award since 2008. My question is…..while undergoing treatment for service connected AO presumption condition, the VA rates that condition 100% and since what I have is debilitating condition that will require treatment rest of my life it is likely to be one more condition that is permanent 100%. Since I already have a service connected condition rated at 100% alone and others that are 70%,70%, 50%, 10%, 10% that is the SMC-S……..is there any other SMC that would increase due to TWO SEPERATE Conditions each stand alone 100% each with others totaling 60% or more?
