Document Summary
Thrombolysis: injection of an agent to dissolve clots and restore some blood flow, thereby reducing the amount of tissue that dies from ischemia. Cancer: a large group of diseases characterized by the uncontrolled growth and spread of abnormal cells. Neoplasm: a new growth of tissue that serves no physiological function, resulting from uncontrolled, abnormal cellular development. Tumour: a neoplasmic mass that grows more rapidly than surrounding tissue. Malignant: very dangerous or harmful; refers to a cancerous tumour. Benign: harmless; refers to a non cancerous tumour. Biopsy: microscopic examination of tissue to determine if a cancer is present. Metastasis: process by which cancer spreads from one area to different areas of the body. Proto-oncogenes: genes that can become oncogenes under certain conditions. Oncologist: physicians who specialize in the treatment of malignancies. Symptoms: cough, blood-streaked sputum, chest pain, and recurrent attacks of pneumonia or bronchitis.
