Benign tumors are abnormal growths of cells that do not spread to other parts of the body, like malignant tumors do. While the exact cause of benign tumors is not known, there are several factors that may increase a person's risk of developing one. These include genetics, environmental exposures, and certain medical conditions.
Genetics
Certain genetic mutations can increase a person's risk of developing benign tumors. For example, people who have a family history of benign tumors are more likely to develop them. Additionally, some genetic syndromes are linked to an increased risk of benign tumors, such as neurofibromatosis and multiple endocrine neoplasia.
Environmental Exposures
Exposure to certain environmental toxins and radiation can increase the risk of developing benign tumors. Radiation exposure is linked to an increased risk of benign tumors of the skin and thyroid. Additionally, some chemicals used in certain industries, such as asbestos, have been linked to an increased risk of benign tumors.
Medical Conditions
Certain medical conditions can increase a person's risk of developing benign tumors. For example, people with chronic liver disease are more likely to develop hepatic adenomas, benign tumors of the liver. Additionally, people with chronic inflammation of the gastrointestinal tract are more likely to develop gastrointestinal stromal tumors (GISTs), benign tumors of the digestive tract.
