Tumors
A tumor is an abnormal growth of cells that forms a mass or lump in the body. Tumors can be classified into three main types: benign, malignant, and premalignant. Benign tumors are non-cancerous and typically grow slowly without spreading to other tissues. Malignant tumors, on the other hand, are cancerous, aggressive, and capable of invading surrounding tissues and metastasizing to distant parts of the body. Premalignant tumors have the potential to develop into cancer over time.
Tumors can arise in any tissue or organ and may be caused by genetic mutations, environmental factors, infections, or chronic inflammation. Common symptoms include swelling, pain, fatigue, and dysfunction of the affected organ, although some tumors remain asymptomatic until they grow large or spread.
Diagnosis often involves imaging techniques like MRI, CT scans, or ultrasounds, coupled with biopsy and histopathological examination to determine the nature of the tumor. Treatment varies based on the tumor type, size, and location, and may include surgery, chemotherapy, radiation therapy, immunotherapy, or targeted drug therapies.
Early detection and timely intervention are crucial in managing tumors, particularly malignant ones, to improve outcomes and enhance the quality of life for affected individua
