I would not think that Chemo will have any effect on the liver tumors in the short term.
And chemo will certainly not clear a bowel colon obstruction in this lifetime.
Having said that, the swollen belly thereby, remains swollen without any relief.
If I have ever heard of a case needing a 2nd opinion quickly, this is it.
Find a Colorectal and Anal surgeon to get a consultation appointment first. All attention should be given to clearing the obstruction and not what an Oncologist thinks!
Sitting around waiting for chemo to kick in is a long term process that will not keep this gentleman alive.
Colon obstruction relief NOW !
