Has anyone else besides me had blood clots In their lungs due to having cancer? I didn't know till after the fact, that cancer patients are highly subseptible to blood clots. Mine was found with a routine CT in July '16. Spent 6 days in partial intensive care. I didn't have any symptoms other than a backache the night before. I have degenerate disc disease and scoliosis so I just thought it was that. I'm on Xarelto cause couldn't regulate with Coumidim.
