I have a friend in his mid 70s who has small cell lung cancer. He has tried Chemo but it was not effective and did a bit of radiotherapy which helped to reduce some of the cancer. Last option, he tried Immunotheraphy for several months but then stopped it because of side effects of inflammation in the lungs. The cancer is growing and he has been given a couple of months to live and has been advised to prepare for the inevitable.
Radiotherapy was a possible option to try again, but can only be used if chemo worked to reduce the cancer and his inflamation of the lungs healed. S
