Welcome to the site! I would never think of doing that, that's just me though, To each their own. My feeling is if there was a better way, it would be the "standard" way of doing it. Chemo sucks, I've had it during 2 diagnoses of cancer, It XXX near killed me. But I believe it's a fact, that if I hadn't had the chemo, the cancer would have killed me.
If you want me to vote, I am plus 1 for the needle, go get it, get it over with, then come back here and join the rest of us survivors.
Best of luck to you, I hope it works for you, whatever you decide to do.
