Gene activated in 80% of breast cancer patients
New research, published this week in Breast Cancer Research, could provide a genetic explanation for breast cancer. A George Washington University Medical Center team, led by Patricia Berg, has discovered that the gene BP1 is activated in 80% of breast cancer patients. The researchers believe that this gene may offer a useful new target for early breast cancer detection and therapy.  more

Guidance: Potassium iodide as a thyroid blocking agent in radiation emergencies
The objective of this document is to provide guidance to other Federal agencies, including the Environmental Protection Agency (EPA) and the Nuclear Regulatory Commission (NRC), and to state and local governments regarding the safe and effective use of potassium iodide (KI) as an adjunct to other public health protective measures in the event that radioactive iodine is released into the environment. The adoption and implementation of these recommendations are at the discretion of the state and local governments responsible for developing regional emergency-response plans related to radiation emergencies. more


Information for patients: Frequently asked questions on potassium iodide (KI)
The effectiveness of KI as a specific blocker of thyroid radioiodine uptake is well established. When administered in the recommended dose, KI is effective in reducing the risk of thyroid cancer in individuals or populations at risk for inhalation or ingestion of radioiodines. KI floods the thyroid with non-radioactive iodine and prevents the uptake of the radioactive molecules, which are subsequently excreted in the urine.  more

Safe handling of human remains of Severe Acute Respiratory Syndrome (SARS) patients: Interim domestic guidance
