6.5 Training at high altitude

Many of the world's best endurance athletes train at high altitudes – a long way above sea level – to improve their performance. At high altitudes there is less oxygen in the air and it's believed that the body has to work harder to extract what little oxygen remains. When the athlete returns to lower altitudes, their body retains the ability to use oxygen more efficiently and their performance will have improved.

Vulvar Cancer: Often Misdiagnosed as an Abscess
Vulvar cancer is rare, with around 4,000 women in the United States diagnosed each year. Doctors often misdiagnose vulvar cancer as an abscess, but if caught early it is highly curable with little disfigurement or sexual dysfunction. Charles Levenback, M.D., and Anuja Jhingran, M.D., both professors in the Department of Gynecologic Oncology at the University of Texas MD Anderson Cancer Center, discuss the basics, diagnoses and treatment of vulvar cancer.
