What is the difference between Hodgkin and non Hodgkin?
The primary difference between Hodgkin and non-Hodgkin lymphoma is the type of lymphocyte that is affected. Hodgkin lymphoma is marked by the presence of Reed-Sternberg lymphocytes, which a physician can identify using a microscope. In non-Hodgkin lymphoma, these cells are not present.
What causes Hodgkin’s lymphoma?
Hodgkin lymphoma is caused by a change (mutation) in the DNA of a type of white blood cell called B lymphocytes. The exact reason why this happens isn’t known. The DNA gives the cells a basic set of instructions, such as when to grow and reproduce.
Why is it called Hodgkin’s lymphoma?
Hodgkin Lymphoma (HL) Is named for Dr. Thomas Hodgkin who, in 1832, described several cases of people with symptoms of a cancer involving the lymph nodes.
How is Hodgkin’s lymphoma diagnosed?
Biopsy. A biopsy is the removal of a small amount of tissue for examination under a microscope. Other tests can suggest that cancer is present, but Hodgkin lymphoma can only be diagnosed after a biopsy of an affected tissue, preferably by removal (or excision) of a lymph node.

Where does Hodgkin’s lymphoma start?
Although Hodgkin lymphoma can start almost anywhere, most often it starts in lymph nodes in the upper part of the body. The most common sites are in the chest, neck, or under the arms. Hodgkin lymphoma most often spreads through the lymph vessels from lymph node to lymph node.
What happens in Hodgkin’s disease?
Hodgkin’s lymphoma is a type of blood cancer that typically develops in your lymph nodes. It causes the abnormal development of a type of white blood cell called lymphocytes. Abnormal development of these cells causes them to replicate uncontrollably and crowd out healthy white blood cells.
