In the United States, the conventional Pap smear has been largely replaced by a liquid-based Pap cytology test.
During the first round of screening, a human papillomavirus (HPV) test detected more abnormal cells grade 3 or worse in the cervix than a Papanicolau (Pap) smear, resulting in a lower liklihood of abnormal cells grade 3 or worse at 48 months.
The cytology-based Pap smear includes searching for tumor or pre-cancer cells by testing cells obtained from the lower end of a female uterus, known as the cervix. detecting the diseases by observing a single cells and little groups of cells is known as cytology or cytopathology.
The findings were published July 3 in the Journal of the American Medical Association.More news: Tropical Depression forms over central tropical Atlantic
In the first round of screening at the start of the study, more cases of CIN3+ were found in women who had HPV tests (7 per 1,000 women) than women who had smear tests (4.4 per 1,000 women). Quite often the smear test can be unpleasant for women, but luckily there is an easier way to screen for cervical cancer risk. But one issue is that it was centered around one ideal system in British Columbia, where they had one place to send all of the Pap smears and HPV testing.
Dr. Gina Suzanne Ogilvie of the Women's Hospital and Health Center in Vancouver and colleagues set up a comparison study. The Pap smear has been around for 50 years, so co-testing remains a viable option, Wright said. So while the HPV test is more sensitive of a test, it isn't ideal and missed some women with early signs of cervical cancer.
Currently, the US Preventive Services Task Force recommends women aged 30-65 receive both a Pap and HPV testing every five years.

One of these methods is co-testing for the human papillomavirus (HPV), which causes 99 percent of cervical cancer. The study inferred that HPV testing could be comparatively much more accurate. Dr Kathleen Schmeler, a gynaecologic oncologist at The University of Texas MD Anderson Cancer Center said, "The bottom line is that it could really potentially simplify how we screen women and have it been more effective and not quite as complicated and burdensome - and opens the door for doing just HPV testing which is actually what's now recommended by the World Health Organisation for countries that don't have Pap testing capabilities".More news: Protester climbs State of Liberty on Independence Day
Women can get a clear result from a simple HPV test and those who receive a negative result will be able to trust those results for several years, she says.
"This is one study", he said. Instead of a physician scraping the cells from the back of a woman's cervix before visually inspecting them for signs of abnormality, an HPV test analyzes cells found in vaginal and cervical secretions. That's what some experts believe after a new study found that the HPV test detects precancerous cervical changes earlier and more accurately. The test is sensitive enough that the results are useful for a longer amount of time, and participants don't need to be re-tested for up to five years after an HPV test.
That kind of early detection is the hallmark of cervical cancer prevention, because health-care providers can take action to treat precancerous cells before they become cancer. But there were still no final guidelines issued on this and that's why the new study might be important in helping with the decision. He called use of the HPV test only a "reasonable strategy" but noted that the test's strength - its sensitivity - could result in more positive results and more testing.
"It's really wonderful, there's no other test that gives us this level of reassurance for that period of time for a cancer", Harper says.More news: Texas DPS charge woman for sale or purchase of a child
