Lymphoma is cancer that begins in cells of the lymph system. The lymph system is part of the immune system, which helps the body fight infection and disease. Because lymph tissue is found all through the body, lymphoma can begin almost anywhere. These can occur in both children and adults. Non-Hodgkin's lymphoma is cancer that originates in your lymphatic system, the disease-fighting network spread throughout your body.Incidence is the total number of new cases of cancer. Mortality is the number of deaths due to cancer.It is estimated that in 2015:
• 8,200 Canadians will be diagnosed with non-Hodgkin lymphoma.
• 2,700 Canadians will die from non-Hodgkin lymphoma.
Some patients may relapse (disease returns after treatment) or become refractory (disease does not respond to treatment). Many of the novel therapeutic agents that have been approved by the United States Food and Drug Administration, as well as those being investigated in clinical trials, focus specifically on those with relapsed or refractory disease. Many effective treatment options exist for NHL patients, including:
• watchful waiting
• radiation therapy
• stem cell transplantation
