For me that is what they did on my tongue they removed the lesion and biopsied it, then called me 2 days later to have me come in , I was supose to come back in 2 weeks , they werent suspecting cancer at ALL ,,they kept saying NO WAY DON"T EVEN THINK IT >>NOT EVEN POSSIBLE . BOY were they WRONG HUH !!

A PET scan reminds me of a CT or an MRI only Not loud like a MRI and it take about 45 min or so in machine I have only had one so I may be mistaken ..someine else may answer better on that subject , But I also had a full body scan . I have heard of false positive , specially after surgery or radiation .

I wish you the Best and WAIT to hear !!! Holding you in thought !!
