Lymphoma means a cancer of the lymphatic system. There are 2 main types of lymphoma: Hodgkin lymphoma and Non Hodgkin lymphoma. Hodgkin lymphoma was named after the doctor who first recognised it. Non Hodgkin lymphomas look different under the microscope and do not contain Reed-Sternberg cells. Approximately 2.1 percent of men and women will be diagnosed with non-Hodgkin lymphoma at some point during their lifetime, based on 2010-2012 data. At 5 years, relative survival was 63% in men and 60% in women. Patients aged 75 or older had a five-year relative survival of 33%
Progress in understanding DNA changes in lymphoma has already provided improved and highly sensitive tests for detecting this disease. Such tests can identify lymphoma cells based on changes such as chromosome translocations or rearrangements or specific gene mutations. Some of these tests are already in use, and others are being developed. Signs and symptoms of NHL include the following: Swollen, painless lymph nodes in the neck, armpits, or groin, Unexplained weight loss, Fever, Night sweats, Coughing, trouble breathing, or chest pain.
