My 74 year old mom was diagnosed with small cell lung cancer in September 2017 and she has been on chemotherapy since then. The main tumor is invading the pulmonary artery. She is in pretty Good condition so far and hasn't had man side effects from the chemo so far.
Could immunotherapy (opdivo/yervoy) be an option even though the tumor is invading the pulmonary artery? Or are there bigger risks associated with treatment with immunotherapy than with regular chemotherapy when the tumor is growing into the artery?
