A risk factor increases your chances of developing cancer. Modifying the following risk factors may help reduce your risk of non-Hodgkin’s lymphoma.

Avoid Exposure to HIV and HTLV-1

Non-Hodgkin’s lymphoma occurs more often in people who have been infected with the human immunodeficiency virus (HIV) and human T-cell leukemia/lymphoma virus than in those who do not have these infections. Steps to avoid HIV and HTLV-1 infection include:

  • Take precautions when engaging in sexual intercourse or any other sexual act that results in an exchange of body fluids. Precautions include:
    • Abstain from sex.
    • Use a latex condom and water-based lubricants.
    • Use a female polyurethane condom.
    • Limit your number of sexual partners.
    • Avoid sexual partners who are HIV-positive or use injected drugs.
    • Do not share hypodermic needles with anyone.

Avoid Repeated Exposure to Certain Chemicals

People who work around pesticides, fertilizers, and solvents have a greater chance of developing non-Hodgkin’s lymphoma than people who are not exposed to these chemicals. Avoiding exposure to such agents may decrease your risk.
