The brothers of the teen 90s trio Hanson are rallying behind their sib, Isaac, as he prepares for another surgery.

On October 4, the eldest bro, 26, underwent a successful operation to remove a life-threatening blood clot that had traveled to both his lungs.

The singer — who is now on extreme amounts of blood thinner to prevent future clots — will undergo surgery in December to remove a rib that is pressing up against a vein.

How is he holding up?

“Isaac is doing well and he's got a clean bill of health," brother Taylor, 24, told Usmagazine.com at a Darfur Now screening in L.A. Tuesday night. "We got back on the road, amazingly [four days after his October surgery]. We are going to take a little break so he can have his surgery. Hopefully it will solve his problem.”

Added Taylor, “We're being very brotherly!”

The trio — which also includes brother Zac, 22 — will spend Thanksgiving together.

So what exactly goes down at the Hanson family holiday?

“It’s just turkey and family and all that!" Taylor told Us. "We like to cook, but it’s usually Grandma, or mom, or anyone who has a recipe. People bring in their part, a little pie, a little turkey!”
