Prostate cancer is classified into different stages according to the size of the tumor and whether the cancer has metastasized. Knowledge about the stage will aid the doctor in selecting an appropriate treatment plan.
The cancer has metastasized and spread beyond the area where it first developed and is now present in nearby lymph nodes or other parts of the body, such as the bones, liver, or lungs.
Many prostate cancers grow slowly; screening decisions should balance the benefits of early detection with the risks of overdiagnosis and unnecessary treatment which may involve PSA blood test & DRE.
