A remarkable recent increase in the diagnosis of vocal-cord cancer in young adults appears to be the result of infection with strains of human papilloma virus (HPV) that also cause cervical cancer and other malignancies. Investigators from Massachusetts General Hospital (MGH) describe finding HPV infection in all tested samples of vocal-cord cancer from 10 patients diagnosed at age 30 or under, most of whom were non-smokers.

A new approach to analyzing prostate gland tissue may help address a major challenge in treating prostate cancer - determining which tumors are unlikely to progress and which could be life threatening and require treatment. In their report published in the journal Scientific Reports, Massachusetts General Hospital (MGH) investigators describe how cellular metabolites - proteins produced as the results metabolic processes - in apparently benign tissues from cancerous prostates not only can determine the grade and stage of the tumor but also can predict its risk of recurrence.
Chlamydia trachomatis is a bacterium that is one of the most common sexually transmitted infections in Europe. Rates in sexually active young people are commonly between 5% and 10%. The number of diagnosed cases is increasing in many European countries, in part due to increased testing and the use of more sensitive tests. People with genital chlamydia may experience symptoms of genital tract inflammation including urethritis and cervicitis, but the majority remains asymptomatic.
