Cancer occurs when normal cells in the body undergo changes that lead to uncontrolled cell growth and division. This process typically begins with genetic mutations, which can be caused by a variety of factors, including exposure to carcinogens (such as tobacco smoke, radiation, and certain chemicals), inherited genetic mutations, viruses, and lifestyle factors (like diet and physical activity).
Under normal circumstances, the body has mechanisms for regulating cell growth, repairing DNA, and eliminating damaged cells. However, when mutations disrupt these processes, they can lead to malignant transformations. As cells continue to divide unchecked, they can form a mass called a tumor. Tumors can be benign (non-cancerous) or malignant (cancerous), with malignant tumors having the ability to invade nearby tissues and metastasize, or spread, to other parts of the body.
The complexity of cancer is also influenced by the microenvironment surrounding the tumors and various factors that affect immune response and cell signaling. Early detection and treatment are crucial in managing cancer, as the disease can progress rapidly if left untreated.
