About Lymphoma
If you or a loved one has been diagnosed with lymphoma, the most common blood cancer and third most common cancer of childhood, the Lymphoma Research Foundation (LRF) is here to help. On this Web site you will find valuable information about the different types of lymphoma - Hodgkin lymphoma and non-Hodgkin lymphoma, diagnostic techniques your health care practitioners may use, and treatment options. Here you can also learn about the latest research findings and get help searching for clinical trials that relate to your condition. The Lymphoma Support Network can help you connect with a peer who is also living with lymphoma or you can find out how to volunteer at an LRF chapter near you. Start by learning more about lymphoma.
