How exactly does lung cancer kill? ?

Question by Jeremy S: How exactly does lung cancer kill? ?
My Mother has had small cell lung cancer for over a year now. The tumor is near her heart. She has had chemo and radiation and was told in October that neither is helping very much and she had only a few months to live.Her voice is hoarse and weak and she coughs to the point of vomiting sometimes but other than that she looks good. She has lost some weight but is still overweight and eats well.

Answer by Eric R
Cells have a natural function to “turn off” or die after a set amount of time. cancer cells have that function turned off, so they just keep replicating and make a massive blob called a tumor. if the tumor, and all infected cells are not removed, it blocks up the lungs and doesn’t allow oxygen into them.
