cancer terminology

Cancer is a disease where abnormal cells grow uncontrollably and can invade nearby tissues or spread to other parts of the body through the blood and lymph. These cells can form lumps or tumors, which may be benign (non-cancerous) or malignant (cancerous). Malignant tumors have the potential to metastasize, meaning they can travel and establish new tumors elsewhere. Treatment options include surgery, radiation, chemotherapy, targeted therapy, and immunotherapy, depending on the type and stage. Understanding these terms helps in comprehending the disease process, diagnosis, and treatment strategies effectively.
