Worldwide, there are nearly 13 million cases of cancer each year. A study published in Lancet Oncology estimates that 2 million (16%) of these cancers are caused by infectious agents.
Viruses, bacteria, and parasites are known to cause human cancers. The most common organisms causing cancer are Helicobacter pylori, hepatitis B and C viruses, and the human papillomaviruses. These infections are largely preventable or treatable.
Researchers looked at 27 cancer cases in 184 countries in eight geographical regions. The percentage of infection-related cancer was highest in developing countries, 23%, compared to 7.4% in developed nations. The cancers caused by these infectious agents include cancers of the stomach, liver, and cervix.
Less than 50 years ago, infection with germs was not thought to be a cause of cancer. However, more than 100 years ago, Ellen White, a 19th century health reformer correctly stated that germs were able to cause cancer.
“Flesh was never the best food; but its use is now doubly objectionable, since disease in animals is so rapidly increasing. Those who use flesh foods little know what they are eating. Often if they could see the animals when living and know the quality of the meat they eat, they would turn from it with loathing. People are continually eating flesh that is filled with tuberculosis and cancerous germs. Tuberculosis, cancer, and other fatal diseases are thus communicated.” Ministry of Healing 313
Today, physicians are skilled at providing immunizations or treatment for these cancer-causing infections. You should seek to avoid situations where you are likely to acquire these cancer-causing infections.
