Patients who have been treated for lymphoma have an increased risk of developing other diseases or conditions later in life because chemotherapy and radiation therapy can cause permanent damage to healthy parts of the body. Treatments have improved in the last 30 years, and now patients who have received treatment for lymphoma recently are less likely to experience late effects. However, there is still some risk. Therefore, it is important for people to receive follow-up care to watch for the late effects explained below.
