neoplasioita

Neoplasia, often referred to as a tumor, is an abnormal and uncontrolled growth of cells in the body. This excessive proliferation arises from genetic mutations that disrupt the normal regulation of cell division and death. Neoplasms can be benign, meaning they are not cancerous and do not invade surrounding tissues or spread to other parts of the body, or malignant, which are cancerous. Malignant neoplasms, or cancers, have the ability to invade nearby tissues and metastasize, spreading to distant sites through the bloodstream or lymphatic system.

The development of neoplasia can be influenced by a variety of factors, including genetic predisposition, exposure to carcinogens such as tobacco smoke, radiation, and certain viruses, and chronic inflammation. The specific characteristics and behavior of a neoplasm depend on the type of cell from which it originates and the specific genetic alterations involved. Diagnosis typically involves medical imaging, biopsies, and laboratory tests to determine the nature and extent of the abnormal growth. Treatment strategies vary widely depending on whether the neoplasm is benign or malignant, its location, and the patient's overall health, and may include surgery, radiation therapy, chemotherapy, immunotherapy, or targeted therapies.
