...HORIZON: THE FIRST CANCER VACCINE A large-scale trial found Merck's experimental vaccine Gardasil 100% effective against two strains of human papillomavirus thought to cause 70% of all cervical cancers. If FDA approved, it may arrive...
Unlike most sexually transmitted infections, human papillomavirus (HPV) typically runs its course without causing illness. Fully half of U.S. adults have been infected without even knowing it. But in a small percentage of cases, the disease progresses to cervical cancer, which kills 4,000 women in the U.S. and 250,000 worldwide each year. Researchers have developed a vaccine that appears to be 100% effective against the two strains of HPV that cause 70% of cervical cancers. The vaccine may be available next year, but is likely to cause controversy if, as expected, it is recommended for girls before they...
...total hysterectomy not as a result of cancer don't need the test, nor do women over 70 who have had three or more normal Pap tests and no abnormal results in 10 years. At least 93% of cervical cancers are caused by the sexually transmitted human papillomavirus; young women who have never had sexual intercourse can skip the screening. The ACS advises, however, that all women get tested three years after starting to have sex or no later than age 21. For the full guidelines, visit www.cancer.org --By Sora Song
...exotic name, but the human papillomavirus is actually a very commonplace sexually transmitted disease. More than half of U.S. women will develop sex-related HPV infections at some point in their life, and in most cases the immune system knocks the virus out before it can do any damage. In some cases, however, the infection becomes chronic, with measurable levels of the virus remaining in the system. Perhaps 5% of these women will eventually develop precancerous lesions that could lead to cervical cancer. Or at least that's what would happen if they did not undergo routine Pap smears, which...
...report released last week, sexual activity decreased 15%. But the incidence of certain sexually transmitted diseases rose among adolescents. A quarter of all new HIV cases today occur in those ages 21 and younger. And doctors are reporting more frequent diagnoses of herpes and the human papillomavirus, or HPV, which is linked to cervical cancer and is thought to infect more than 15% of sexually active teens. The last figure is the one gnawing at some doctors. Though the particulars of HPV remain something of a medical mystery, we have learned at least one frightening thing about the disease...
