  • Risk factors for thyroid cancer

    Risk factors for thyroid cancer Risk Factor - this is what increases the likelihood of developing cancer.

    For example, strong sunlight on the skin - a risk factor for skin cancer.

    Smoking - a risk factor for lung, mouth, larynx, bladder, kidney and other organs.

    but the presence of one or more risk factors does not say that a person is required to develop cancer.

    To date, there are several factorswhich increase the risk of thyroid cancer. But the majority of patients with thyroid cancer is no obvious risk factors. Furthermore, many people with the presence of one or more risk factors for thyroid cancer is not developed at all. If a person has one or more risk factors, it is impossible to draw conclusions about how certain factors affect the occurrence of cancer.


    Low iodine food

    Papillary and follicular thyroid cancer is more common in areas of the world where there is a low content of iodine in food.
    In some countries, especially iodine salt is added to the food, and other foodstuffs.


    Radiation

    Prove a risk factor for papillary cancerThyroid cancer is head and neck irradiation in childhood. In the past, children underwent irradiation about acne, fungal infections of the scalp, an enlarged thymus gland and to reduce the size of the tonsils or adenoids. After a few years, this type of treatment is associated with increased risk of developing thyroid cancer. Radiation exposure in adults is accompanied by a slight risk of developing thyroid cancer.

    Number of studies have shown that increasingthe risk of thyroid nodules in the thyroid gland, and even cancer, due to radioactive fallout during nuclear weapons tests or incidents at nuclear power plants. Thus, the observed increase in the incidence of thyroid cancer among children about the Ukrainian city of Chernobyl, where the explosion occurred at the plant in 1986. At the same time, millions of people have been exposed to radioactive fallout. Do rescue workers and people living near the place of incident, as there is an increased incidence of thyroid cancer, even though they were older at the time of the accident.


    Hereditary condition

    People with certain hereditarydisease also have an increased risk of developing thyroid cancer. Thus, Gardner's syndrome and familial polyposis are accompanied by an increased risk of thyroid cancer. Rare genetic disease Cowden (Cowden) is also associated with an increased risk of thyroid cancer. 20% of medullary thyroid cancer are the result of an inherited altered gene - familial medullary thyroid carcinoma.


    Age and Gender

    Benign thyroid nodulescancer occur more frequently in women than in men. Most cases of papillary and follicular cancer is detected at the age of 30-50 years. Benign and malignant tumors of the thyroid gland can occur in people of all ages.


    Risk factors related to lifestyle

    Tobacco and alcohol - the main factorsat most risk of head and neck tumors, including tumors of the mouth, pharynx, esophagus. On the other hand, it is proved that these factors increase the risk of thyroid cancer.
