Core Tip
Core Tip: Despite the decline in incidence and mortality during the last decades, stomach cancer is one of the main health challenges worldwide. According to the GLOBOCAN 2020 estimates, stomach cancer caused approximately 800000 deaths, and ranks as the fourth leading cause of deaths from cancer in both genders combined. Around 1.1 million new stomach cancer cases were diagnosed in 2020. There are some well-established risk factors for stomach cancer: Helicobacter pylori infection, dietary factors, tobacco, obesity, and radiation. To date, the most important way of preventing stomach cancer is reduced exposure to risk factors, as well as screening and early detection.
