Is good news or bad?

Went with my uncle for his radiation intro today. While looking thru his MRIs, both the doc and I saw something a little strange...a mass, 23.6 mm big, on the anterior superior portion of his bladder. The cancer, which was originally on the base of the bladder is definitely non-exsistent. The Hopkin's doc did an internal scope and found no abnormal cells.

Normal bladder cells are transistional epithelial--which means their shaped to expand and contract. Here is what they look like:

Cancerous cells in the bladder look like this:

(Notice the irregular shaping of the cancer cells. The smoothness of the plasma membrane is not consistent.)

The radiological oncologist has ordered a PET scan for Monday. I will be at the follow-up visit next Thursday. For now, we wait.
