Hey there... "pairof" family... thanks for the reply.
You're right that some lymphoma patients will have substantial anemia as part of their disease, and the treatment can make it worse.
I think that during the next several weeks I need to gauge, and try to improve my general conditioning, especially in view of the high probability of my anemia worsening. Seems like simple treadmill will give me a reasonable yardstick. If I can increase my general aerobic capacity, then clearly that will enhance my ability to enjoy diving. Conversely, if it declines, despite a conscious attempt to improve it, then this may be the answer I need to confront, squarely in the face.
And I appreciate the advice to watch out for the hogfish. Since we are very much novice divers, I anticipate that we might just dive the reefs, and leave wrecks for a future date. My only prior experience has been SNUBA in Hawaii, and SCUBA in the USVI, and I split my dives between wearing a shorty (3 mm) and no wetsuit at all. It seems wise to assume that I ought to wear a suit for Key Largo in January - - and I am beginning to think that we might be wise to wait until a little later in the spring. Not so much for water temperature as for sun and fun weather (and let some hair grow back to reduce my risk of sunburned scalp!)
And for anyone else following this thread, here is some additional info, regarding the link lisred above. One of the more promising listings was "Undersea Medicine Associates" which, with a quick Google, I located the web page
www.scubamed.com operated by "Dr. Fred" (Fred Bove MD, PhD) with lots of information. i have sent my original inquiry to him, and I have received a preliminary reply. He has also proposed starting an entry on the blog portion of his web page about diving after cancer therapy.
My continued thanks to everyone on this forum for making me feel welcome here with my questions.
