Question by : My friend is coughing up blood a sign of lung cancer ?
My friend coughs up blood after playing any king of sport. She is 14 years old. Is it possible she is having lung cancer ?
No one in her family smokes but she says that she had been exposed to some passive smoking.
Answer by Michelle
The best bet is that her nose bleeds and it’s going to her throat. If not, it can be a very serious lung issue.
