It is the most commonly diagnosed cancer in men. It is sometimes indolent, sometimes mortal; it causes little or no symptoms at first and is completely curable when detected at an early stage. Although it strikes men over fifty, through research and early treatment, as well as more effective methods, the survival rate is 100% five years after the date of diagnosis when there is no spread elsewhere in the body. Hence the importance of screening for middle-aged men. In Quebec, twelve (12) men are diagnosed daily.
