users, not sharing hypodermic needles. The more sexual partners an individual has during his or her lifetime, the greater are the chances of contracting sexually transmitted infections like HIV or HPV. Safe sex consists of limiting the number of sexual partners and using a condom. For intravenous drug users, sharing needles with an infected person poses the risk of contracting HIV or infection with hepatitis B or C.

      People who receive organ transplants sometimes take medications to suppress the immune system so that the body will not reject the organ. These drugs are immunosuppressive, and like environmental pathogens, weaken the body's immune system so they cannot adequately destroy cancer cells or resist infections associated with cancer.

      Transplant recipients have a higher risk of developing several different types of cancers, some of which are directly linked to infectious agents, and others not. The four most common cancers among transplant recipients, which develop more frequently in these individuals than in the general population, include non‐Hodgkin lymphoma (NHL), lung, kidney, and liver cancers. NHL has been shown to be associated with EBV infection.

Having too much body fat is associated with many forms of cancer, as discussed previously. Doctors recommend eating nutritious and filling foods, including whole grains, vegetables, fruits, and beans, and replacing sugary beverages with low‐ or no‐calorie drinks. It is also helpful to drink lots of water to help flush any toxic chemicals from the body.
