Book Description: The lymphatic system plays a key role in fighting out the bacteria infested in the human body. More importantly, aiding in the fight against disease. Inside the lymphatic system, lymph vessels widen to produce lymph nodes. These lymph nodes usually appear under the arm or neck of those who are sick or infected. If cells continue to swell or multiply, they can often be considered as cancerous. Lymphoma is the actual type of cancerous cell that spreads throughout the lymphatic system. One main group of cells that spread within lymphatic system is Hodgkins Disease, which is recognised by its growth of Reed-Sternberg cells. This book presents cutting edge research from around the world.
