Forget feeling like a million bucks. Ethan Zohn is feeling like a new man.

The "Survivor: Africa" champ underwent a stem-cell transplant Wednesday to treat a recurrence of his Hodgkin's lymphoma cancer--and he has his brother to thank for the immuno-boost.

Outwit, outlast, outplay has never quite meant so much.

"Today I leap into a healthy new body. Today is the start of the rest of my life. Thank You to my bro Lee &all who have supported me. Love!" the reality star tweeted presumably before undergoing the transfusion.

And of course, Jenna Morasca, Zohn's girlfriend and winner of "Survivor: The Amazon," was right there with him the whole time.

"Thanks @JennaMorasca for being by my side. Love you," he added in a follow up.

Just before the transplant, Morasca wrote on Twitter: "Today @EthanZohn gets new stem cells &new cancer free life FOREVER! And we get our lives back. Send positive healing vibes #getbetterethan"
