DENVER, Colo., April 20 – Human lung tumors have the ability to eliminate Vitamin D, a hormone with anti-cancer activity, a new study from the University of Pittsburgh Cancer Institute
Human lung tumors have the ability to eliminate Vitamin D, a hormone with anti-cancer activity, a new study from the University of Pittsburgh Cancer Institute (UPCI) suggests. Results of the study, Abstract Number 2402, are being presented at the 100th annual meeting of the American Association for Cancer Research (AACR), April 18 to 22, in Denver.
"High levels of Vitamin D help the body produce proteins with anti-tumor activity," explained principal investigator Pamela Hershberger, Ph.D., a research assistant professor in UPCI's Department of Pharmacology and Chemical Biology. "We've discovered that lung cancer cells make an enzyme called CYP24, which counteracts the positive effects of Vitamin D. To better study it, we developed the first radioactive-free assay that measures the amount of Vitamin D in tissues and blood."
Lung Cancer - Types, Causes, Symptoms, Diagnosis, Treatment and Prevention
Lung cancer is a malignant tumor in the lung tissues. Smoking is the main cause of lung cancer with symptoms like recurrent respiratory diseases.

Lung cancer is the leading cause of cancer death in the United States in both men and women, killing 160,000 people annually, and remains one of the most difficult cancers to treat. The five-year survival rate remains low, and better treatments are much needed. According to Dr. Hershberger, it is possible that one day Vitamin D could be used as a chemopreventive agent to improve patient outcomes.

Lung Biopsy - Indications - Procedures - Risks - FAQs - Reference
The procedure by which tissue samples are obtained from the lung is known as lung biopsy. The biopsy tissues obtained from the lungs are examined by a pathologist.

The Lungs
The lungs are our organs of respiration. It is within these, that exchange of gases takes place.
