What is Endocrinology - Describe thyroid cancer's epidemiology.
One of the rare malignancies that has seen a rise in absolute incidence and mortality over the past several decades is thyroid cancer; in 2012, there were predicted to be 56,400 new cases diagnosed and 1780 fatalities. With an average 5-year survival rate of 97 percent of patients, relative survival has improved since the 1970s. An improvement in imaging has led to a large number of new thyroid cancer diagnosis. Since the late 1990s, 50% of the growth has been attributed to the discovery of tumours smaller than 1.0 cm. However, a research indicating that improved identification of incidental malignancies is not the only reason for the increasing incidence suggests that up to 20% of the rise in diagnoses are for tumours larger than 2.0 cm. Women are three times more likely to develop thyroid cancer than males, making it the seventh most frequent disease in women overall. Men tend to experience more aggressive thyroid cancer, but the fatality rates for both sexes are comparable.
