Carcinogens are defined as 'a substance or agent that can cause cells to become cancerous by altering their genetic structure so that they multiply continuously and become malignant'. [1] The World Health Organization breaks down the three types of carcinogens that can cause cancer in humans. The first type of carcinogen is the physical type ...
A carcinogen (/ k ɑːr ˈ s ɪ n ə dʒ ən /) is any agent that promotes the development of cancer. [1] Carcinogens can include synthetic chemicals, naturally occurring substances, physical agents such as ionizing and non-ionizing radiation, and biologic agents such as viruses and bacteria. [2]
Rates of 17 cancers have been rising among each generation since the baby boomers, with more young people being diagnosed below age 50 than in the past, new research suggests.
Since 1% to 3% of infected individuals are likely to develop gastric cancer, [109] H. pylori-induced gastric cancer is the third highest cause of worldwide cancer mortality as of 2018. [110] Infection by H. pylori causes no symptoms in about 80% of those infected. [111] About 75% of individuals infected with H. pylori develop gastritis. [112]
