You’re probably thinking about non-small cell lung cancers. Small cell lung cancer (SCLC) is still absolutely devastating. The most progress made on SCLC has just been getting people to stop smoking, as its almost exclusively a smoker’s disease.
Anyways, I studied SCLC in grad school and saw lots of scans of people with tumors from their heads to their feet, and saw the enormous resources dedicated to caring for SCLC patients and to searching for a cure. It’s hard to overstate how profoundly evil the cigarette companies were and still are. They got people (children) addicted knowing what was coming for them, knowing they were killing them in horrific ways. Now we all get to pay for that in funerals and tax dollars.
