How did Chernobyl cause thyroid cancer?

Why did Chernobyl affect thyroid?

As radioactive iodine decays, it emits radiation and affects the thyroid and the nearby tissue. This process destroys thyroid cells as well as the surrounding capillaries preventing blood supply with oxygen and food.

Did Chernobyl cause thyroid problems?

It is estimated that more than 6,000 cases of thyroid cancer were caused by the disaster. “The Chernobyl accident is a clear example of the health consequences experienced by a large population exposed to radioactive iodine,” says Memorial Sloan Kettering physician-scientist James A. Fagin.

How did thyroid cancer become widespread in the region after the Chernobyl disaster?

External exposure to ionizing radiation produces DNA damage and increases the rates of cancers such as thyroid, lung, and breast cancers and leukemia [5]. The most dramatic effect on physical health resulting from exposure to fallout from the Chernobyl disaster has been an increased incidence of thyroid cancer [6, 7].

How does radiation cause thyroid cancer?

Most nuclear accidents release radioactive iodine into the atmosphere, which can be absorbed into the body. When thyroid cells absorb too much radioactive iodine, it can cause thyroid cancer to develop several years after the exposure.

Was Poland affected by Chernobyl?

The radiation monitoring station in Mikołajki, Mazury area (north-eastern region of Poland) showed that the radioactivity in the air was 550,000 times higher than the day before. The radioactive cloud from Chernobyl had travelled to Poland. The story of the catastrophe began here.

Why did people drink iodine after Chernobyl?

Taking a large dose of iodine, in theory, will sate your body’s hunger for the substance and prevent you from absorbing the iodine-131 once it arrives. … But after Chernobyl, the most significant release of radioactive iodine ever, there was a spike in thyroid cancer in children in the affected area.

Was Chernobyl affected by Istanbul?

Turkey has been affected by radioactive clouds of the nuclear reactor by two fronts. The first impact was on the western parts of Turkey including Istanbul and Western Black Sea coast beginning from April 30th 1986. Eastern Black Sea coast was affected by a second cloud at the beginning of May 1986.

Did Chernobyl affect Turkey?

After the Chernobyl reactor accident, Eastern Black Sea coast was one of the heavily contaminated regions of Turkey. Clouds loaded with radioactive isotopes arrived the region on May 1986 and emptied their contents with the heavy rains that are frequently seen in the region.

Does thyroid cancer shorten your life?

Virtually all patients with cancer are concerned about their life expectancy. Although patients with thyroid cancer usually have normal life expectancy when treated appropriately, there are many whose life span is limited by the thyroid cancer.

What is the main cause of thyroid cancer?

The cause of thyroid cancer is unknown, but certain risk factors have been identified and include a family history of goiter, exposure to high levels of radiation, and certain hereditary syndromes.

Where Does thyroid cancer spread first?

Most patients with thyroid cancer have the cancer contained in the thyroid at the time of diagnosis. About 30% will have metastatic cancer, with most having spread of the cancer to the lymph nodes in the neck and only 1-4% having spread of the cancer outside of the neck to other organs such as the lungs and bone.
