New understandings about thyroid cancer.
There is an increased risk of thyroid cancer associated with lower-than-normal thyroid hormone levels, a finding that could have a major impact on patients fighting the disease.
The Yale-led study, published in American Association for Cancer Research journal examined the effect of Thyroid Stimulating Hormone (TSH) on the development of human papillary thyroid cancer (PTC).
Study findings were based on 741 participants (341 women, 400 men) from the U.S. military who had regular blood draws stored by the Armed Forces Surveillance Center. When tested, an inverse association between PTC and TSH levels within the normal range was observed among both men and women. PTC decreased with increased TSH levels among both men and women, the researchers found.
