Lymph Node News and Research

RSS

Lymph is clear or white fluid that travels through vessels, moves within tissues and work to keep all the parts of the body clean. After passing through the channels of the lymphatic system they drain into the lymph nodes. The lymph nodes act as filters along the lymphatic system. These nodes trap germs like bacteria, viruses, toxins as well as cancer cells and ensure that these are removed from the body.

Quantum dots detect metastatic lesions

By injecting quantum dots into tumors, investigators at Carnegie Mellon University have been able to image sentinel lymph nodes in animals using near-infrared light. These results could lead to a simple, non-invasive method for detecting metastasis.

Study shows why the body's immune system doesn't attack tissues in the small intestine

Answering one of the oldest questions in human physiology, researchers at Dana-Farber Cancer Institute have discovered why the body's immune system - perpetually on guard against foreign microbes like bacteria - doesn't attack tissues in the small intestine that harbor millions of bacteria cells.

FDA expands use of Herceptin

The U.S. Food and Drug Administration (FDA) has expanded the approved use of Herceptin, a biological cancer drug. The new indication is for Herceptin, in combination with other cancer drugs, for the treatment of HER2 positive breast cancer after surgery (lumpectomy or mastectomy).

Race is associated with unfavorable breast cancer tumor biology

African-American women with breast cancer were more likely to have larger, later-stage tumors that were more difficult to treat and also had lower survival rates than Hispanic and Caucasian women who received the same treatment in two independent series of clinical trials examined by researchers from The University of Texas M. D. Anderson Cancer Center.
