What is Lymphoma?

Lymphoma

Quick Answer

A type of cancer that affects the lymphatic system, lymphoma involves the uncontrolled growth of lymphocytes, a kind of white blood cell. It can be classified mainly into two types: Hodgkin lymphoma and non-Hodgkin lymphoma.

Overview

Lymphoma is a cancer that starts in the lymphatic system, which is part of the body's immune system. This system helps fight infections and diseases, and it includes lymph nodes, spleen, and bone marrow. When someone has lymphoma, their lymphocytes, which are crucial for fighting infections, begin to grow uncontrollably, leading to tumors and other health issues. There are two main types of lymphoma: Hodgkin lymphoma and non-Hodgkin lymphoma. Hodgkin lymphoma is marked by the presence of Reed-Sternberg cells, while non-Hodgkin lymphoma encompasses a diverse group of blood cancers. Understanding these types is important because they can behave very differently, and their treatment may vary significantly. Lymphoma matters because it can affect anyone and often requires prompt medical attention. For example, a person might notice swollen lymph nodes or experience unexplained weight loss, which could lead them to seek medical help. Early diagnosis and treatment can greatly improve outcomes, making awareness of lymphoma and its symptoms essential.
