Detailed explanation-1: -Stage I: The cancer is localized to a small area and hasn’t spread to lymph nodes or other tissues. Stage II: The cancer has grown, but it hasn’t spread. Stage III: The cancer has grown larger and has possibly spread to lymph nodes or other tissues. Stage IV: The cancer has spread to other organs or areas of your body.
Detailed explanation-2: -Malignant tumors are cancerous (ie, they invade other sites). They spread to distant sites via the bloodstream or the lymphatic system. This spread is called metastasis. Metastasis can occur anywhere in the body and most commonly is found in the liver, lungs, brain, and bone.
Detailed explanation-3: -Cancer is malignant because it can be “locally invasive” and “metastatic": Locally invasive cancer-The tumor can invade the tissues surrounding it by sending out “fingers” of cancerous cells into the normal tissue.
Detailed explanation-4: -The process of carcinogenesis may be divided into at least three stages: initiation, promotion, and progression.
