Thyroid Disease and Breast Cancer
by Mary J. Shomon

At present, the coincidence of both breast cancer and thyroid disorders is still a subject of extensive debate. More research is needed into the connections between thyroid disease and breast cancer. This becomes even more important, given the recent findings that indicate that thyroid disease is far more prevalent that originally thought, and there are an estimated 13 million Americans unaware of and undiagnosed for their current thyroid conditions.

Some of the research is saying...
  • Thyroid cancer in younger women increases their risk for breast cancer five to twenty years later.
  • Thyroid hormone has a direct and crucial role in the development of breast cancer.
  • Non-toxic goiter (an enlarged thyroid) was more than twice as common in the breast cancer patients.
  • Use of thyroid supplements does not increase the risk of developing breast cancer.
  • The prevalence of thyroid disorders is increased in patients with breast cancer, and thyroid autoimmune disorders, especially Hashimoto's thyroiditis, account to a large extent for the increased prevalence of thyroid disease in patients with breast cancer.
More details and links to this research are available online.
