Scientists discover a genetic switch that links animal growth and cancer

Many animals similarly halt their development until the environment is right for growth and development." The process is the same with cells, the basic units of life. Many cells remain in a quiescent state, neither gro...Possible cause and potential treatment found for aggressive head and neck cancer
