Lymphoma is a cancer that develops in the lymphatic system and is caused by the rapid and uncontrolled growth of abnormal lymphocytes, a type of white blood cell which plays an important role in the immune system and fights infection.
There are two types of lymphoma:
- Hodgkin lymphoma – unlike other lymphomas, Hodgkin lymphoma features the presence of the Reed-Sternberg cancer cell
- Non-Hodgkin (NHL) – also known as B and T cell lymphomas. Types of non-Hodgkin lymphoma that occur in children and young adults include lymphoblastic lymphoma, Burkitt lymphoma and large cell lymphoma
According to the Singapore Childhood Cancer Registry, lymphoma is the third most common childhood cancer in Singapore and accounts for 10% of all childhood cancer diagnoses.
