I just had my 6 month follow-up scan from my RAI treatment for papillary carcinoma. I took a tracer dose and went back the next day for a full body scan. There was no uptake in my neck, great thing, but uptake in one of my salivary glands. I was concerned but the nuke med doctor and my endo said this was nothing to worry about, as uptake in the salivary glands was normal. My endo says from the results of my scan, I am cancer free. is it indeed normal to have uptake in the salivary glands? just looking for a little more confirmation. Should I be concerned? Thank you!
