? Liver secondaries

Hi, I am concerned.

My husband had his right Kidney & ureter removed for urethelial cancer on the 27th March.

At that time his blood tests showed that his ALT  &  ALP were a little raised. 1 week post operation his ALT shot up to over 600 & his ALP to over 400.

He is having his blood rechecked this Thursday., the hospital will ring him the next day with his results. 

Can removing the kidney & ureter trigger release of cancer cells  into the liver via the blood stream with in a week. Then cause secondaries?

He is on antibiotics for a post op bacterial wound infection.

I know I am apprehensive & we dont know what stage the cancer is at yet. I'm reading lots & don't understand lot's.

Thank you for being there
