The stages of cancer helps in predicting the size of the cancer tumor and how far it's spread. Most cancers that involve a tumor are staged in five broad groups. Other kinds, like blood cancers, lymphoma, and brain cancer, have their own staging systems.
Stage 0 means there's no cancer, only abnormal cells with the potential to become cancer.
Stage I means the cancer is small and only in one area. This is also called early-stage cancer.
Stage II and III mean the cancer is larger and has grown into nearby tissues or lymph nodes.
Stage IV means the cancer has spread to other parts of your body. It's also called advanced or metastatic cancer.
A physical exam and several tests can be used to estimate how far the cancer has spread.
