<s>[INST] My 2 (3 in Sept) year old has dried blood in his ear and down into the canal as far as I can see with a flashlight.  Ive searched for possible answers online and come up with everything from a simple scratch to cancer.   He has ear tubes and the tube from his other ear fell out about a year ago.  As far as we know this tube is still in place.   What can this be from?  No other symptoms.  He says his ear doesnt hurt but I am concerned that it could be something serious.   Any advice would be appreciated! [/INST] Hi, dairy have gone through your question. I can understand your concern. Bleeding from ear may be due any causes.  Trauma, Otis media or cancer or brain pathology all can lead to bleeding.  However, chances of cancer are very low.  Most common cause is Otis media or external. You should go to ENT specialist for examination.  Then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health. </s>
