My wife was nice enough to do a little research. She suggested for The Susan B. Komen folks in Las Vegas that there is something called R.E.D. Rose Support Services to help with transportation and that sort of thing. You'll want to check into this more directly, of course, at 1-702-616-7525.
There may be some possible help with co-pay assistance through Susan B. Komen as well. You'll need to check the details. Try at this number — 1-866-512-3861.
The American Cancer Society number in L.V. is 702-798-6877. I'm not sure what services you might access through them, but it might be worth checking.
At any rate, the Susan B. Komen folks should be able to help you get rides to appointments and if funds get a bit tough, they may be able to help with groceries — I'm unclear on that last part. There is supposed to be that definite program for co-pay assistance whose number I gave above, and it's my wife, Elaine, who was able to do the research. I'm merely passing her work (happily, I must say) along.
Good luck to both of you.
I know that the both of you are clearly non-Catholics, but it's worth passing on that Catholic Charities is often helpful in connecting people with rides and sometimes other stuff. If you're interested, the numbers I have here for those folks are 702-385-2662 and 702-387-2291.
All my best, Bob Kaven
