Good vibes being sent his way. Later, when he starts chemo, see if he wants to use cannabis for the nausea. There are several studies in the link in my sig, if he wants proof that it works better than the usual anti-nausea medicines. Cannabis interferes with the growth of many kinds of cancer, but I don't know which type of lymphoma he has. I have a lot on leukemia, but only a couple on lymphoma. Here's what I could find-

AAMC: Cannabinoid Receptor Agonists May Be Novel Class of Anti-Lymphoma Agents

Cannabinoids As Cancer Hope - NORML


The Leukemia and Lymphoma Society also has endorsed the use of medical cannabis.

Mom sounds rather religious. If she is also anti-cannabis, try this- it's from the BBC, no less!- BBC NEWS | Health | Cannabis linked to Biblical healing
And then there's this- Cannabis and the Christ: Jesus used Marijuana

She might be a bit more accepting to the idea of cannabis for chemo after reading those two.
