Strange Lump

We've just noticed this reddish lump on the inside of our 11 month old's ear. Any idea's on what this may be? Thanks, Darren

Hello!   - indeed, I could give you an interesting list of possibilities that it 'might' be, but while some of them are quite benign, others are unpleasant and even life-threatening, so we would encourage you to find out what it actually is.  It doesn't look like a tick in this picture, but that can be difficult online.  Usually your vet could rule out ticks for you very quickly.  Your vet may not be able to tell you a diagnosis right away either:  an unpleasant lump can sometimes look very similar to a benign one, so  they may wish to take a sample of one kind or another.  Is it painful?  As a general rule, cancer is not (but can become so - and inflammatory lesions can sometimes appear painless too, so this isn't fool-proof).   It seems a very good idea to pay you vet a visit and get the ball rolling.  Best of luck - and please do let us know.
