Today I will undergo the 17th radiation treatment on my squamous cell carcinoma and initial signs of radiation burn are appearing on both sides of my throat. I am applying Aquaphor to treat it. I did find out that my tumor is HPV positive and the size of the tumor is already shrinking significantly. My side effects are mild, so far, compared with those others in this thread have experienced-a mild sore throat along with moderate swallowing difficulty. If no more significant issues develop, I will consider myself fortunate.
