The stages of cancer are typically categorized as follows:
1. Stage 0: Also known as carcinoma in situ, where abnormal cells are present but have not spread. 2. Stage I: Cancer is localized to a small area and has not spread. 3. Stage II and III: Larger tumors or cancers that have spread to nearby tissues or lymph nodes. 4. Stage IV: Cancer has spread to distant parts of the body, known as metastatic cancer.
