Here's what I found a while back when seeking info about tumor necrosis. 1) Necrosis in the tumor means that the cancer cells in that area are dead. The pathologic finding of necrosis suggests a fast-growing cancer. This often happens because the tumor runs out of blood supply in the central portion. Without a blood supply, the tumor cells cannot live.
Football cleats also come in the removable and molded variety. Molded cleats tend to be less expensive and are often required for youth play for safety reasons.

Football kickers choose their shoes based on a variety of factors, including turf or grass surface, weather conditions, comfort, and support. Natural grass is the optimal surface for a kicker except when it is wet. On natural grass, the kicker would want to wear a detachable cleat.n artificial turf (carpet-like), the kicker should wear a turf shoe. A turf shoe is similar to a tennis show with multiple built in cleats. This offers more grip on this particular surface, as well as more support and traction, especially on the planted foot.
