While there’s no way to prevent lymphoma, you can reduce your overall risk for cancer by keeping healthy habits. Don’t smoke, eat well, and stay active. If you do develop lymphoma, these basic health measures may make it easier for you to handle the treatments needed to fight the disease. People who are healthier on the whole fare better when undergoing cancer treatment.
Most of the time, there’s no clear reason why lymphoma develops.
Already having another form of cancer called human T cell leukemia/lymphotropic virus or a type of bacteria called Helicobacter pylori can also increase the risk of developing lymphoma, as can being exposed to certain pesticides, solvents, and fertilizers (such as nitrates), and for non-Hodgkin lymphoma, herbicides.
