Anyone with experience with visceral Mast Cell tumors

My (non diabetic) boy Tammuz is supposed to start radiation for his (extremely rare in cats) bladder cancer next week. However his ultrasound that found the cancer (done for not eating well) showed his entire small bowel was inflamed and the radiologist (who is a wizard) thought the spleen looked a little questionable so did a FNA of spleen. Mast cell tumor.

Idk if the bowel is also MCT or something else. Tbh I expected lymphoma and was praying for IBS. Idk if he’s going to make it to deciding about splenectomy since bladder takes priority. I won’t know until Monday what his oncologist thinks of his new diagnosis (he doesn’t work Thur or Fri when his results came back). Dr Google doesn’t have much good news about intestinal MCT (if that’s what this is). He certainly can’t have his entire small bowel removed and even splenectomy worries me (I’m seeing a surgeon Monday to discuss a ureteral stent, that appointment also made before this came back, I can see what he thinks of Muz is even a candidate anymore

Posting here bc there’s not much written about treating intestinal MCT so I hope someone knows something

I belong to a groups.io group on feline small cell lymphoma, and there's been a few references to internal MCT there. You have to join the group, but they tend to limit to people who have had a SCL diagnosis or going through the process of getting a diagnosis. One mention was about a cat whose biopsy (that verified SCL) was taken while removing a MCT. Good luck with the oncologist visit.
 
Thanks. I’ve not had luck with .io boards anyway so I’m ok with not being able to join. I’ve pretty much maxed out my bandwidth. By Wednesday of next weeks it will be ten days and he will have been twice to the oncologist (3 hour drive each way), twice to radiologist (40 min each way) and once to our vet; I will also have been an additional 4 trips to take urine to vet or pick up supplies for tests, and once to the surgeon (40 min each way). And I called pretty much every surgeon between San Francisco and Los Angeles, and every oncologist between Santa Barbara and Davis. It’s easier to get a human Dr on the phone.

From what I’ve found it’s not horrible if you find it only in the spleen. It’s best if you find it only on the skin. It’s pretty bad if it’s in the intestine or liver but usually it’s not found there and technically I don’t know if Muz has it. He could of course have three separate unrelated cancers but less likely. Two at the same time is unusual enough but I’ve already had a cat with two unrelated cancers. I imagine if he gets his stent (or they remove his spleen ) they might biopsy his intestine
 
The hard part now is getting him to eat. It’s been a struggle for a year (hard to convince anyone that it was a problem since he was gaining weight despite not eating). He barely eats his regular food and has no interest in new foods for the most part. When he does like something he gets diarrhea. I’m really worried about possible urinary retention from Benadryl (since he’s already having problems from the tumor) but am going to try a dose tomorrow in off chance it helps his GI problems.
