My friend with a stage 4 squamous cell carcinoma has been bleeding in the mouth for a week now. It's not continously bleeding,but sometimes when he wakes up he finds blood all over his pillow. His doctor told him it's normal. His cancer is inoperable now acording to the doctors. We are now just managing his pain to make him comfortable. The bleeding scares me. Does anyone here knows anything about it? Is it normal symptom of that disease?
