Understanding Mitosis and Its Role in Cancer Development

Mitosis is a fundamental process of somatic cell division, crucial for growth and repair in the body. It is controlled by genes, hormones, and environmental factors. However, uncontrolled mitosis can lead to cancer, a significant health concern with statistics showing that 1 in 7 individuals will face some form of cancer in their lifetime, and lung cancer remains the leading cause of cancer deaths in the U.S. This educational overview explores the causes of various cancers, such as skin, colon, breast cancer, leukemia, and lymphoma, emphasizing the importance of understanding mitosis in cancer prevention.
