A new study confirms earlier findings that human papillomavirus (HPV) DNA-based test are more accurate than Pap smears in finding precancerous tumors.

A study from the Centers for Disease Control and Prevention estimates that 25 percent of the country's teenage girls, or almost 1 of 4 young girls, may have sexually transmitted diseases.

Girls aged 14 to 19 who are sexually active may have human papillomavirus (HPV), which is the leading cause of cervical cancer among women later in their lives. Other diseases are Chlamydia, trichomoniasis, and herpes simplex virus

The Centers for Disease Control and Prevention released a study Tuesday showing that one in every four adolescent girls in United States, aged between 14 and 19 years, has been infected with sexually transmitted disease (STD).

The authors of the study said that there were at least 3.2 million teenage girls between aged 14 and 19 currently infected with common STDs

One in four American teenage girls has at least one common sexually transmitted disease (STD), the new study said Tuesday. It is the first study carried out by the U.S. Center's for Disease Control (CDC) that examines the combined national prevalence of common STDs among adolescent women in the United States.

CDC says that at least 3.2 million teens aged 14 to 19 are currently infected. This accounts for 26 percent of the total girls that have human papilloma virus, chlamydia, genital herpes or trichomoniasis

new virus called Merkel cell polyomavirus or MCV, which is linked to a rare but lethal type of skin cancer, has been discovered by an American researcher. MCV, according to a study by the University of Pittsburgh Cancer Institute published Thursday, is the first virus to be associated with a specific type of cancer.

The cancer, Merkel cell carcinoma (MCC), mainly affects people with weak immune systems including AIDS patients and those who recently underwent transplant procedures. Nearly 1,500 cases of Merkel cancer are reported annually. Around 50 percent of the patients with advanced stages of the cancer survive for nine months only
