Rates of SCC have remained fairly stable or have even fallen over the past few years, but those of adenocarcinoma have risen, particularly in high income countries.

The researchers used data from Cancer Incidence in Five Continents volume 10 to calculate age, sex, and country specific proportions of the two types of esophageal cancer. These figures were then applied to IARC global data on the number of new esophageal cancer cases in 2012 (GLOBOCAN 2012), and age-standardised rates calculated. …

Miller, Ph.D., associate professor of cancer biology at Wake Forest Baptist. "However, sometimes the immune system becomes unresponsive to the presence of these cells and a tumor develops." This unresponsiveness can be temporary, and the immune system can remain alerted to the fact that there’s a problem. Immune cells can stand post along the borders of the tumor and even infiltrate the tumor core, where they may gain a better position for eventual attack. …
