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.
In association football, where the shoes themselves are known as football boots, there are three different cleat types. There are soft ground cleats which are made for wet weather. The soft ground cleats are always replaceable, and are almost always metal, so when they wear down they are easy to replace.
1 If you buy a shoe with detachable cleats, buy replacement cleats in a variety of sizes and make sure you have a cleat wrench to remove and replace cleats. 2  Replacement cleats generally run in 1/2-, 5/8-, 3/4- and 1-inch sizes.ootball cleats are made both for the position you play and the type of field where you play. Keep these two important factors in mind when you purchase your football footwear.
