I am a 25 year old male with a very stressfull occupation. I found a dime size painless lump under my jaw line on the right side. I have allergies to air irritants but I am not currently suffering from the symptoms and I don't have a cold. The left side has no lumps. Please help. (although no blood relation i just had a family member diagnosed with cancer in the same area) So I am very worried. Please Help.
