The main infection-related cancers are stomach, liver, and cervix.
Lung cancer is largely due to non-infectious causes, such as tobacco smoke. However, liver and stomach cancer are primarily due to infectious causes. Liver cancer is largely caused by infectious hepatitis B virus (HBV) plus hepatitis C virus (HBC) and stomach cancer is largely caused by Helicobacter pylori bacteria.
What are the types of infectious diseases? Infectious diseases can be viral, bacterial, parasitic or fungal infections.
There are many conditions that can cause masses or lumps in soft tissue that have nothing to do with tumors. An infection or abscess is perhaps the most common cause behind a mass that is mistaken for a tumor.
Yet, many bacteria directly manipulate their host cell in various phases of their infection cycle. Such manipulations can affect host cell integrity and can contribute to cancer formation.
The risk of infection increases when large numbers of people are in a small space for a long time. In addition, sharing glasses and chopsticks increases the risk of infection. Long-term meals, dinner receptions, drinking alcohol at night increase the risk of infection compared to a short meal.
Risk of infection is a nursing diagnosis which is defined as "the state in which an individual is at risk to be invaded by an opportunistic or pathogenic agent (virus, fungus, bacteria, protozoa, or other parasite) from endogenous or exogenous sources" and was approved by NANDA in 1986.
"Big Three" Infectious Diseases: Tuberculosis, Malaria and HIV/AIDS.
Person to person spread. This is the most common way that we get an infectious disease. Germs can spread from person to person through: the air as droplets or aerosol particles.
An introduction to the infectious causes of cancer can be found here. Human tumor viruses account for an estimated 12% to 20% of cancers worldwide. Viruses can lead to cancer by associating with host proteins, proliferating when the human immune system is weakened, and hijacking proliferating human cells.
Some patients are at greater risk than others-young children, the elderly, and persons with compromised immune systems are more likely to get an infection. Other risk factors are long hospital stays, the use of indwelling catheters, failure of healthcare workers to wash their hands, and overuse of antibiotics.
COVID-19 is often more severe in people 60+yrs or with health conditions like lung or heart disease, diabetes or conditions that affect their immune system.
I – Infection – may have signs and symptoms of an infection.
Sometimes however, you may have an infection and not know it, and not have any symptoms. Keep this in mind especially if you have recently had surgery or an invasive medical procedure, a break in your skin, or you have been exposed to someone who is ill.
Antibiotics are medicines that help stop infections caused by bacteria. They do this by killing the bacteria or by keeping them from copying themselves or reproducing. The word antibiotic means “against life.” Any drug that kills germs in your body is technically an antibiotic.
The spleen is a blood-filtering organ that removes microbes and destroys old or damaged red blood cells. It also makes disease-fighting components of the immune system (including antibodies and lymphocytes).
Eventually, the CD4+ T cell population becomes so depleted that the individual starts to experience other, opportunistic, infections. This marks the beginning of the final phase, commonly known as acquired immune deficiency syndrome or AIDS, which eventually results in death.
Some symptoms associated with blood infections or sepsis are: Severe pain in the body. Rash or blotchy skin. Sweaty or clammy skin.
