Tumors are caused by the abnormal growth and division of cells in the body. Normally, the body controls cell growth and division, with new cells being created to replace older ones or to perform new functions. However, when the balance of cell growth and death is disturbed, a tumor may form. Factors that can lead to the development of tumors include gene mutations, inherited conditions, environmental toxins, excessive sunlight exposure, genetic problems, obesity, radiation exposure, and viruses. Additionally, tumors can be caused by changes to DNA, which can occur due to errors during cell division, damage to DNA caused by harmful substances in the environment, or inherited genetic mutations. The causes of benign tumors, which are not cancerous, may be linked to environmental toxins, genetics, diet, stress, and local trauma or injury.
In summary, tumors can be caused by a variety of factors, including genetic mutations, environmental toxins, excessive sunlight exposure, genetic problems, obesity, radiation exposure, viruses, and changes to DNA. These factors can disrupt the normal balance of cell growth and death, leading to the formation of tumors.
