GeneSearch Breast Lymph Node Assay reduces recurrence of breast cancer

A new test that examines large sections of the sentinel lymph node for genes expressed by breast cancer could reduce the risk of recurrence and multiple surgeries, doctors say.

Mechanism of blood clot elasticity revealed in high definition

Blood clots can save lives, staunching blood loss after injury, but they can also kill. Let loose in the bloodstream, a clot can cause a heart attack, stroke or pulmonary embolism.

New discovery, immune cells confront viruses just inside of the lymph node

Vaccines have led to many of the world's greatest public health triumphs, but many deadly viruses, such as HIV, still elude the best efforts of scientists to develop effective vaccines against them. An improved understanding of how the immune system operates during a viral infection is critical to designing successful anti-virus vaccines.

U.S. Food and Drug Administration approves new genetic breast cancer test

The U.S. Food and Drug Administration has approved a test that helps in assessing the risk of tumor recurrence and long-term survival for patients with relatively high-risk breast cancer. The TOP2A FISH pharmDx is the first approved device to test for the TOP2A (topoisomerase 2 alpha) gene in cancer patients.
