Prevention of lymphoma
Can lymphoma be prevented?
-There are few known preventable risk factors for lymphoma, so it is not possible to prevent most cases of the disease at this time.
-For now, the best way to reduce the risk for lymphoma is to try to prevent known risk factors such as immune deficiency.
Human immunodeficiency virus (HIV)
-Infection with HIV is a preventable cause of immune deficiency.
-HIV is spread among adults mostly through unprotected sex and by injection drug users sharing contaminated needles.
-Blood transfusions are now an extremely rare source of HIV infection.
-Curbing the spread of HIV would prevent many deaths from lymphoma.
-Treating HIV with anti-HIV drugs also lowers the chance of developing lymphoma.
-Preventing the spread of the HTLV-1 could have a great impact on lymphoma in areas of the world where this virus is common.
-The same strategies used to prevent HIV spread could also help control HTLV-1.
Human T-cell leukemia/lymphoma virus (HTLV-1)
-Helicobacter pylori infection has been linked to some lymphomas of the stomach.
-Treating H. pylori infections with antibiotics and antacids may lower this risk, but the benefit of this strategy has not been proven yet.
-Most people with H. pylori infection have no symptoms, and some have only mild heartburn. More research is needed to find the best way to detect and treat this infection in people without symptoms
Helicobacter pylori
-Another risk factor for lymphoma is infection with the Epstein-Barr virus (the cause of infectious mononucleosis, or mono), but there is no known way of preventing this infection.
-Some lymphomas are caused by treatment of cancers with radiation and chemotherapy or by the use of immune-suppressing drugs to avoid rejection of transplanted organs.
-Doctors are trying to find better ways to treat cancer and organ transplant patients without increasing the risk of lymphoma as much.
-But for now, the benefits of these treatments still usually outweigh the small risk of developing lymphoma many years later.
-Some studies have suggested that being overweight or obese may increase the risk of lymphoma.
-Other studies have suggested that a diet high in fat and meats may raise the risk.
-Maintaining a healthy weight and eating a healthy diet may help protect against lymphoma, although more research is needed to confirm this.
-Some early studies have suggested that giving antibiotics to people with H pylori infection may lower the number of pre-cancerous lesions in the stomach and may reduce the risk of developing stomach cancer.
-But not all studies have found this.
-More research is needed to be sure that this is a way to prevent stomach cancer in people with H pylori infection.
-Avoiding risk factors when possible can lower a person's stomach cancer risk, but it cannot guarantee protection from this disease.
-Early detection may be the best way to improve the chance of successful treatment and reduce the number of deaths caused by the disease
