Non-fibrous particulate materials that cause cancer include powdered metallic cobalt and nickel, and crystalline silica (quartz, cristobalite, and tridymite). [32] Usually, physical carcinogens must get inside the body (such as through inhaling tiny pieces) and require years of exposure to develop cancer. [32] Common occupational carcinogens ...
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]
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]

In the United States, 20% of the population will be older than 65 years of age by the year 2030. Those 85 years and older will be the most rapidly growing group. [1] This is compounded by the fact that the majority of cancer patients will be in this age group. Age in itself is one of the most important risk factors for developing cancer.
Tobacco smoke, for example, causes 90% of lung cancer. [50] Tobacco use can cause cancer throughout the body including in the mouth and throat, larynx, esophagus, stomach, bladder, kidney, cervix, colon/rectum, liver and pancreas. [51] [52] Tobacco smoke contains over fifty known carcinogens, including nitrosamines and polycyclic aromatic ...
While men, since the later 1900s and particularly in the ’90s, have had a higher cancer incidence than women, incidence rates in women 50-64 years of age have now surpassed those in men.
The leading cause of death in both males and females is lung cancer, which contributes to 26.8% of all cancer deaths. Statistics indicate that between the ages of 20 and 50 years, the incidence rate of cancer is higher amongst women whereas after 50 years of age, the incidence rate increases in men.
