Hi @cjabad, I moved your question to the Colorectal Cancer support group to help connect you with other members who have had a diagnosis of rectal cancer like @paul28 @martin77 @apinzonc0627 @pkanders52 and others.

I'm sorry to hear that you are feeling light headedness. I don't think I or anyone can say it is related or unrelated to the polyp. But I do know that they are likely to check your heart before surgery to make sure that your heart is strong. At least that is what they did for my dad. Do you have a history of heart issues?

You mention that you will be getting a Gallium-68 Dotatate PET/CT Scan. Has it been determined that the cancer is a neuroendocrine tumor?
