M Stage

The M stage in cancer staging stands for "Metastasis," which refers to whether the cancer has spread to other parts of the body beyond the original tumor. If the M stage is classified as M0, it means no spread has been detected. If it is M1, it indicates that the cancer has metastasized to distant sites, such as other organs or tissues. Understanding the M stage helps determine how advanced the cancer is and guides treatment decisions. It is a key component in assessing the overall stage of the cancer, affecting prognosis and management strategies.
