Most lymphomas of the skin have no known cause, so there is no sure way to prevent them from developing.
Having a weakened immune system may raise your risk of skin lymphoma, so making sure your immune system stays healthy might be one way to limit your risk.
An example of this would be to avoid known risk factors for infection with HIV (the virus that causes AIDS), such as
:
Intravenous
(IV)drug use
Unprotected sex with someone whose HIV status is unknown
