Lymphoma, better known as Hodgkin's Disease, is a condition characterized by the presence of Reed-Sternberg cells. In addition to Hodgkin's, there are many other lymphoma diseases which are known as Non-Hodkin's lymphoma. Non-Hodgkin lymphoma incidences become more and more common with age, whereas Hodkin's lymphoma is common between ages 16 and 35, and over 50.

The most common sign of Hodgkin's lymphoma is swollon lymph nodes, mainly in the neck. This is not painful, however some of the other expected symptoms are. These other symptoms are unexplained weight loss, constant fatigue, itchy skin, low grade fevers, and night sweats. As these are common symptoms of any infection, the only accurate diagnosis is through lymph node biopsy and blood testing.

Unlike Hodgkin's lymphoma, Non-Hodgkin's lymphoma is a type of cancer. In the united states, 5% of cancer victims are due to Non-Hodgkin's lymphoma. Signs of this disease are similar to that of Hodgkin's, with a few differences. As well as in the neck, swollon lymph nodes are common in the underarm and groin. And in addition to itchy skin, patients will notice unexplained red patches.

Non-Hodgkin's lymphoma must be tested for as well, using things such as X-rays, MRI's, CT scans, PET scans, and Lymphangiogram, which are pictures of the lymphatic system taken with x-rays after a dye is injected to differentiate the lymph nodes and vessels. These tests are due to the simple fact that the symptoms are common in many other, less critical, conditions.
