Non-Hodgkin lymphoma (NHL), also known as non-Hodgkin's lymphoma, is a group of blood cancers that includes all types of lymphomas except Hodgkin lymphomas. Symptoms include enlarged lymph nodes, fever, night sweats, weight loss, and tiredness. Other symptoms may include bone pain, chest pain, or itchiness. Some forms are slow-growing while others are fast-growing. Unlike Hodgkin lymphoma, which spreads contiguously, NHL is largely a systemic illness.

In the present book, twelve typical literatures about Non-Hodgkin lymphoma published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on Non-Hodgkin lymphoma. We hope this book can demonstrate advances in Non-Hodgkin lymphoma as well as give references to the researchers, students and other related people.
