Reuters Examines WHO Efforts To Fight H1N1 In Developing Countries
Reuters examines the WHO"s battle against the H1N1 (swine flu) virus in "[d]eveloping countries, where medical care systems are weak and supplies of antivirals insufficient." In addition to "supplying countries with diagnostic kits, medicines and masks and gloves to protect health care workers and minimize the further spread of the new virus," the WHO is continuing to distribute doses of the antiviral Tamiflu, which has been "shown to be effective so far against H1N1," according to Reuters.

What Is Colon Cancer? What Causes Colon Cancer?
proteins or DNA - so that cancer cells will commit suicide. These treatments target any rapidly dividing cells (not necessarily just cancer cells), but normal cells usually can recover from any chemical-induced damage while cancer cells cannot. Chemotherapy is generally used to treat cancer that has spread or metastasized because the medicines travel throughout the entire body. Treatment occurs in cycles so the body has time to heal between doses. However, there are still common side effects such as hair loss, nausea, fatigue, and vomiting. Combination therapies often include multiple types of chemotherapy or chemotherapy combined with other treatment options. Radiation Radiation treatment, also known as radiotherapy, destroys cancer by focusing high-energy rays on the cancer cells. This causes damage to the molecules that make up the cancer cells and leads them to commit suicide. Radiotherapy utilizes high-energy gamma-rays that are emitted from metals such as radium or high-energy x-rays that are created in a special machine. Radiotherapy can be used as a standalone treatment to shrink a tumor or destroy cancer cells, and it is also used in combination with other cancer treatments.

Side effects of radiation therapy may include mild skin changes resembling sunburn or suntan, nausea, vomiting, diarrhea, and fatigue. Patients also tend to lose their appetites and have trouble maintaining weight, but most side effects subside a few weeks after completing treatment. How can colon cancer be prevented? Regular screening - especially after age 50 - is one of the best ways to prevent or detect colon cancer. The American Cancer Society suggests screening tests such as fecal occult blood tests (annually), stool DNA testing, flexible sigmoidoscopy (every 5 years), colonscopy (every 10 years), and CT colongraphy (every 5 years). These frequency recommendations depend, however, on a person"s particular risk of colon cancer due to other risk factors. Some drugs may also reduce a person"s risk of colon cancer. These include aspirin, NSAIDs like ibuprofen and naproxen, and COX-2 inhibitors such as Celebrex. In general, physicians recommend standard preventive measures such as keeping a healthy weight, exercising, and increasing consumption of fruits, vegetables, and whole grains while decreasing saturated fat and red meat intake. In addition, people are recommended to limit alcohol consumption and quit smoking.
