Hi everyone,
Here is the update on my dad. He saw the oncologist today; a wonderful man, very kind, patient, thorough, explained everything and answered all our questions. He showed us the 3 spots on the liver the PT scan picked up. He said they don't look like cysts but it's possible they are not cancerous either. My dad's going for a biopsy this Friday (which the Dr. assured me was safe for him) and he took blood, one is for a special test which shows if colon cancer is present anywhere in his body. The PT scan was clear everywhere else, lungs, lymph nodes, etc. (YAY!) My dad's excellent health and feeling good are good signs as well. There was no swelling, etc. when he examined him. If the spots are cancerous, they are quite treatable with a chemo which doesn't sound nearly as scary as some we've heard about, it actually sounds pretty simple, and he said he wouldn't even lose his hair. If the spot(s) are still there, then he said they could be zapped with radiation. He'd want to do chemo first because in case there are spots they do not see, the chemo would kill those too whereas doing radiation first might allow smaller, unseen spots to pop up later.
So it looks not so bad for now, thank goodness. I will keep you updated, and thank you all from the bottom of my heart for your good thoughts. I hope you are all doing well, and I will send my positive thoughts in your direction as well.
