It can be classified as either benign or malignant, with the latter being cancerous. Benign tumors are usually non-cancerous and do not spread to other parts of the body, whereas malignant tumors have the ability to invade nearby tissues and spread to other organs through the bloodstream or lymphatic system. Tumors can arise from various cell types and can exhibit a wide range of signs and symptoms, depending on their location and size. The causes of tumors are multifactorial and can include genetic mutations, environmental factors, and lifestyle choices. Diagnosis often involves imaging tests, biopsies, and laboratory examinations. Treatment options for tumors include surgery, radiation therapy, chemotherapy, immunotherapy, targeted therapy, and hormone therapy, among others. The prognosis and treatment outcome are influenced by various factors, including the type and stage of the tumor, as well as the overall health of the patient. Regular screenings and early detection play a crucial role in identifying tumors at an early and more manageable stage.
