Any type of fast-growing lymphoma that isn't Hodgkin lymphoma is called a high-grade non-Hodgkin lymphoma (NHL).  This type of blood cancer happens when something goes wrong with the development of certain white blood cells (B lymphocytes or T lymphocytes).

More than 5,500 people find out they have a form of high-grade NHL each year in the UK.

The most common type is diffuse large B-cell lymphoma (DLBCL), but there are a number of others such as Burkitt lymphoma and mantle cell lymphoma.  Most of the information in this section will be relevant to people with all types of high-grade NHL, but do speak to your healthcare team about which parts of this information are relevant to you.
