Hello,

The only thing I could find online that gave me a hint as to what this may be caused by is radiation damage to thyroid or pituitary gland. When I was getting radiation for my breast cancer, the beams did hit the collarbone area and up the side of neck a bit..

Has anyone else experienced any thyroid issues after cancer treatment? Please tell me of your experience(s) if you’ve been down this road.

Could this be a sign of thyroid cancer?

Thank you
