Cancer - Essay Example However, in the recent times, the incidence of cancer has been on the rise (Dein, 2006, p. 35). There are various dietary, genetic, lifestyle related and environmental factors that could cause cancer (Dein, 2006, p. 35). Medical experts associate this trend with a range of factors such as pollution, smoking, stress, improper dietary choices, faulty lifestyles, substance abuse, genetics and the like, which negatively influence the cell division mechanisms in the body and lead to cancerous tumors in different human organs (Dein, 2006, p. 35). To put it in simple words, cancer happens to be an uncontrolled division of cells in an organism’s body (Weinberg, 1999, p. 1). In a healthy individual the division of body cells is systematic and controlled and facilitates many important body functions and physiological developments. However, in case this cell division gets uncontrolled, it may form a tumor, the name attributed to a mass of abnormal cells (Weinberg, 1999, p. 1). As cancero us tumors are composed of abnormal cells, they do not serve any healthy function in an organism’s body. Rather, an unobstructed growth of cancerous tumors obstructs the normal working of the healthy tissues and in extreme cases, if not checked through medical intervention, may cause death (Weinberg, 1999, p. 1). Cancers are caused by a variety of reasons or factors. They may infect any part or tissue in a body. Many a time cancers are caused by genetic disorders (Adrouny, 2002, p. 7).
