neoplázií

Neoplázie is a medical term referring to abnormal and uncontrolled cell growth. This uncontrolled proliferation of cells, also known as neoplasm, can result in the formation of a mass or tumor. Tumors can be benign, meaning they are not cancerous and do not spread to other parts of the body, or malignant, meaning they are cancerous and have the potential to invade surrounding tissues and metastasize.

The development of neoplázie is a complex process driven by genetic mutations that alter the normal cell cycle. These mutations can be caused by various factors, including exposure to carcinogens, viruses, and inherited predispositions. The abnormal cells may divide more rapidly than normal cells or fail to undergo programmed cell death, leading to an accumulation of cells.

Diagnosis of neoplázie typically involves medical imaging, such as X-rays or CT scans, and a biopsy, where a sample of the abnormal tissue is examined under a microscope. Treatment depends on the type, stage, and location of the neoplasm and can include surgery, radiation therapy, chemotherapy, or immunotherapy. Early detection and intervention are crucial for improving outcomes in cases of malignant neoplázie.
