human cancer

Human cancer is a disease where some cells in the body grow uncontrollably and spread, forming a mass called a tumor. Normally, cells grow and divide in a regulated manner, but genetic mutations can disrupt this process. These abnormal cells can invade nearby tissues or travel through the blood and lymphatic system to spread to other parts of the body, a process called metastasis. Factors like genetics, environment, and lifestyle influence cancer risk. Treatment options include surgery, radiation, chemotherapy, and targeted therapies, aiming to remove or destroy cancer cells while minimizing harm to healthy tissue.
