In developing countries, a new, inexpensive treatment allows nurses to spot pre-cancerous lesions on a woman's cervix and remove them—without needing a medical lab, and without surgery. It has huge implications for women's health, because cervical cancer kills 250,000 women every year.
In fact, before pap smears became commonplace, cervical cancer killed more American women than any other sort of cancer. But in places where the pap smear isn't practical, this new technique can help. From the New York Times:
Nurses using the new procedure, developed by experts at the Johns Hopkins medical school in the 1990s and endorsed last year by the World Health Organization, brush vinegar on a woman’s cervix. It makes precancerous spots turn white. They can then be immediately frozen off with a metal probe cooled by a tank of carbon dioxide, available from any Coca-Cola bottling plant.
... Dr. Bandit Chumworathayi, a gynecologist at Khon Kaen University who helped run the first Thai study of VIA/cryo, explains that vinegar highlights the tumors because they have more DNA, and thus more protein and less water, than other tissue.
It reveals pre-tumors with more accuracy than a typical Pap smear. But it also has more false positives — spots that turn pale but are not malignant. As a result, some women get unnecessary cryotherapy. But freezing is about 90 percent effective, and the main side effect is a burning sensation that fades in a day or two. By contrast, biopsies, the old method, can cause bleeding.
