I'm 17- nealy 18 and I've had cancer twice in the past 4 years, I've had 30 sessions of radiotherapy twice, on both sides of my neck and one side of my face.
Ive noticed a pea-sized lump behind my ear that is firm and can move around under the skin, it's been there for months. Could it possibly be cancer even though I've had 2 lots of radiotherapy to that area? Or could that trigger another cancer cell to grow? My next MRI is in a month- ((i'v also had all of my lymph nodes removed so it couldn't possibly be an inflamed one.) Could it?
