Hello Jimjams81, 

The best thing to do in your situation is to go and see your doctor to get  the lump and symptoms checked out.  When you are worried that you may have cancer, it can be tempting to look for answers on an online forum, but this can end up increasing anxiety rather than making you feel better.  And the only person that can diagnose you is your doctor so do make an appointment when you can. 

I hope this is helpful 

Best wishes,
