Also, this is not a "growth" as you thought but swelling from an immune response. Turkeys are prone to nasal infections and that's probably what this is.
Heck if I know, I just care about the animal first. The animal's health is more important than me having excess meat. Plus I don't kill my own birds to eat them. No matter how they die, I bury them with tears in the backyard.
I had a turkey with that exact thing. It was a bacterial infection. Some Orbax and eyedrops of kinds cleared it right up. Vet prescription may be required.
