As an oncologist with extensive experience in cancer research and treatment, I can provide a detailed explanation of what Stage 4 cancer entails. Stage 4 cancer is the most advanced stage of cancer and signifies that the disease has metastasized, meaning it has spread from its original site to other parts of the body. This is also referred to as advanced or metastatic cancer.
