Survivors of thyroid cancer can be affected by a number of health problems, but often their greatest concern is facing another cancer. Cancer that comes back after treatment it is called a recurrence. But some cancer survivors may develop a new, unrelated cancer later. This is called a second cancer.
Breast cancer is the most commonly diagnosed cancer among women in the United States, and thyroid disorders affect millions of American women. Many breast cancers are sensitive to hormones like estrogen, and according to researchers, thyroid hormone has estrogen-like effects at high levels. So, for years, scientists have wondered whether having too much thyroid hormone might promote the development of breast cancer. The thyroid is a butterfly-shaped gland at the base of the neck that produces thyroid hormone. Thyroid hormone affects almost every cell in the body and has many crucial functions, like controlling metabolism, heart rate, and body temperature. Some people have hyperthyroidism, or an overactive thyroid, in which the thyroid gland produces too much thyroid hormone. This can cause weight loss, thinning hair, sweating, anxiety, and a rapid heartbeat.
Background: Recent studies indicate a possible relationship between hypothyroidism and breast cancer in vivo. In addition, oestrogen-like effects of thyroid hormones on breast cancer cell growth are seen in vitro. Therefore, this study evaluated thyroid function in breast cancer patients, women with benign breast tumour and healthy controls. Thyroid history was reported.
As more people are being diagnosed with thyroid cancer, and survival rates are generally excellent, there are more survivors of thyroid cancer. Previous studies done in patient populations from a small number of institutions showed an increased risk for breast cancer in women with a history of thyroid cancer. The cause for this is unclear, but genetic changes, radiation exposure, and hormonal factors have been considered. It was also done to further explain the elevated risk for breast cancer in female survivors of thyroid cancer.
