Insight from my brother

My brother went through lymphoma about 8 years ago and shared with me his experience.  He allowed me to share his email:

Mine was large b-cell non-hodgkins lymphoma on the thyroid Stage 1  I had 3 rounds of chemo followed by 4 weeks of radiation (which was no worse than getting an x-ray).  Even though my tumor went from close to my heart into my neck, I was still given a greater than 90% chance of cure. (3 continuous years of remission).
Lymphoma is one of the few cancers that we are able to cure.  All the doctors will tell you the most important thing is a positive attitude.  So don't read the internet.  That will really terrorize you because they talk worst case so much.  So swallow any pride and take any and all help people offer.  If they say "What can I do?" ask them to help with a meal or two when you are too busy helping her to cook.  Assign them something when they ask.
If she get the similar treatment that I did. you will need little things that will make a difference later.

Plastic silverware.  The metal taste in her mouth will end up getting to her.
Alcohol free mouth wash. Biotene is a good brand.
Small servings of something she likes.  Fruit cups, bananas something she can put in her stomach when the drugs say don't take on empty stomach.
Ginger ale and ginger snaps.  Ginger is a natural relief for nausea.  Just make sure it has real ginger, not flavoring
I know you are anti-drugs, but if she has a big problem with nausea and not wanting to eat, you would be amazed what a joint would do to help her.  Ask the doctor about Marinol if it gets that way.  Marinol is a synthetic THC they can legally prescribe.

It will bother you to see her lose her hair if she has same treatment as I did, but you have to look at it that each hair that falls out represents cancer leaving her body.  That bothered mom to see me bald.
I have no doubt they you two will come through this with few scratches.  Call me anytime if you want to talk about what my treatment was like.
