Hey. I'm sorry to hear about your diagnosis.
I was treated for a rare form of Hodgkin's Lymphoma early last year. 4 months of chemotherapy. In my case ABVD.
Chemotherapy as a term doesn't mean much. Find out what your specific diagnosis and treatment protocol is. They will give you a pamphlet outlining any potential side effects and I say potential because you may or may not experience them.
Side effects from one protocol to the next can vary.
You will most likely be sent to a chemo teach. It's very broad and covers many different chemotherapy side effects that may or may not apply. Don't worry about it. There will be some useful stuff there.
if you are going to the Agency here you will be receiving incredible care. Those guys are amazing. So focus your attention elsewhere: diet and exercise.
Stay active. Weights and an aerobic program both short in duration can be ideal (20 minutes or so). Walk as much as you can. Develop a dietary strategy. Focus your attention on these two. You will have to work around your surgery but it's doable.
I'm riding faster and stronger than when I went in. That is in spite of a very tough treatment protocol. Staying active made a massive difference and was a big surprise to the team there.
PM me if I can help you in any way. I'm headed to the island this am and can be back later.
