Hint: Cancer is a disease that develops when cells in the human body split more quickly than normal. These abnormal cells grow into a lump or tumour. Thyroid cancer is a disease in which malignant (cancer) cells form in the tissues of the thyroid gland. Thyroid nodules are common but generally are not cancer.
Complete step-by-step answer:
Thyroid cancer is the growth of cells that begins in the thyroid. The thyroid is a butterfly-shaped gland found at the base of the neck, just under Adam's apple. The thyroid produces hormones that control blood pressure, heart rate, body temperature, and weight.
Radioiodine (sodium\[{I_{131}}\]) is a form of radiation therapy that were used for several years to treat thyroid conditions. It is safe and effective but needs humans to observe specific precautions to reduce the small amount of radiation that other people may receive from the body and bodily fluids.
\[R{a_{224}}\] is a short-lived, alpha-emitting isotope detected in the groundwater and soils, Radium-224 was used in biomedical treatments.\[R{a_{224}}\] in drinking water is a potential health hazard because of its carcinogenic effects. In the first days after intake, radium heavily focuses on the endosteal bone. Because of the 3.5-day half-life, most\[R{a_{224}}\]decomposes while on bone surfaces, possibly producing sarcomas in cells within a range of the radiated alpha particles.
\[{C_{14}}\]is a weakly radioactive isotope of Carbon; also called radiocarbon, it is an isotopic chronometer. The richest, carbon-12, remains constant in the atmosphere. Meantime, \[{C_{14}}\]is radioactive and breaks down into nitrogen-14 over time. Every 5,730 years, the radioactivity of \[{C_{14}}\]decomposes by half. That half-life is important to radiocarbon dating.
Therefore the correct answer is Option A.
Note: Thyroid cancer might not cause any symptoms at first. But as it grows, it can cause symptoms and signs, like swelling in the neck, voice changes, and difficulty swallowing.
