Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells. If left untreated, cancer can invade nearby tissues and spread to other parts of the body through the bloodstream and lymphatic system. It can develop in almost any organ or tissue, with risk factors including genetic predisposition, lifestyle choices, and environmental exposure to carcinogens.
Cancer has a significant impact on the U.S. healthcare system, accounting for billions in medical costs annually. The disease requires specialized treatment, long-term care, and advanced medical technologies, placing strain on hospitals, insurance systems, and research institutions. Early detection and preventive measures are essential in reducing the burden on healthcare providers
Cancer treatment also influences healthcare accessibility and policy, as high treatment costs can create financial challenges for patients. Innovations in personalized medicine, early screening programs, and emerging therapies continue to improve survival rates and quality of life, while ongoing research aims to enhance prevention and treatment strategies.
