Final answer:
Esophageal cancer is more common in males, especially those over the age of 50, and can vary by ethnicity, with African or Asian descent individuals showing higher incidence rates.
Step-by-step explanation:
Esophageal cancer is more commonly diagnosed in males, particularly in those older than 50 years of age. The exact cause of this discrepancy is not fully understood, but lifestyle factors such as smoking and alcohol consumption, which are generally more prevalent among men, may contribute.
Furthermore, certain ethnicities display a higher incidence of esophageal cancer, with some studies showing increased rates in individuals of African or Asian descent. It's important to recognize that these are general trends and individual risk can be influenced by a variety of factors including genetics, environmental exposures, and diet.
