>>Lung cancer is not the automatic death sentence that some other kinds are, like brain or pancreatic.
Brain tumors, as long as they are primary ones and not the aggressive ones, are actually some of the “best” kinds of cancer to get (assuming there is such a way to think about best). They are very treatable and the side affects are minimal. Secondary tumors (what we mean by 3rd and 4th stage diagnosis) make things difficult to say.
I will say this: just saying a stage followed by the type is not indicative of anything any more. A friend of mine discontinued all treatments for late stage melanoma 2 and a half years ago. She’s now cancer free. Another friend just passed after a year and a half battle with pancreatic cancer. Some pancreatic cancer diagnoses results in days or weeks of life.
Although I probably shouldn’t say this, it really troubles me that a very troubled human being like RBG still lives with multiple cancers and someone like my friend didn’t. But, that’s not for me to decide.
Everyone I have known who got a glioblastoma (brain cancer) has died, usually between 18 months-3 years from diagnosis. But I do agree, it depends on which type you get.
