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. Detachable football cleats are made of rubber, hard plastic or metal and come in a variety of lengths for use on different playing surfaces.
Best Answer: It depends. Old school turf, aka astroturf, no way. Thats the bright green stuff that rips up your knees. Field turf or any of the newer turf fields, yes, you can wear anything from sneakers to turf shoes to cleats. Some fields have policies on what you can or can't wear but every turf field I have ever played on for football or lacrosse, I have worn either molded cleats or spikes. Source(s):
