Ok so earlier today, while playing Graal on my iPad. I notice blood started dropping down from my face onto the iPad. I went to go get a paper towel and started to wipe the blood off my nose. After a min or two I began to cough, kinda like when you have a cold. Some blood started to come out and there was like a blood ball kinda a mix between blood and mucus. I'm a bit scare, once I saw something similar happened on a tv show. Instead of bleeding from both mouth and nose it was just the nose. Could it be possible I have cancer? I am 16 year old, weight 154lbs, approximately 5"10-5"11 I'm standard built guy. I do about 1-2 hours of exercise a day half is cardio and half is weight training. I have not told anyone about this and I'm scare I might be diagnosed with cancer. Please let me know if it's just a minor thing. I did some research and it said it could've been the weather.
