Lymphoma or blood cancer depicts a variety of cancers in the lymphatic system and is the most common cancer to occur in children and young adults. The lymphatic system helps to fight bacteria and diseases but when a disorder develops the cells in the system start to multiply uncontrollably.

Two of the most common of the 30 existing types of lymphoma are the more common Non-Hodgkin's lymphoma and less common Hodgkin's Lymphoma, or Hodgkin's disease. Hodgkin's disease is far more difficult to discover than the Non-Hodgkin's lymphoma and occurs mostly in people aged over 50.

The symptoms are very similar to some passing health problems – chills, swelling of lymph nodes, fever, night sweats, weight loss, itching, but when the symptoms have appeared for a long time it is strictly recommended to see the doctor to make sure through x-rays and tests whether or not you have lymphoma. 

The risk factors have not been fully determined but NHL is believed to be either hereditary, develop as a result of a virus (hepatitis, Epstein-Barr), in people being exposed to pesticides, as a result of an organ transplant or in people with autoimmune disease.  HL is believed to be also hereditary or develop in people infected with the Epstein-Barr virus or HIV.

The disease has been cured successfully with chemotherapy or radiation therapy and bone marrow or stem cell transplantation may also be used. Most patients having HL usually live long lives after successful treatment, but NHL has a higher percentage of recurrence.
