It's not yet clear if the drug Gardasil, the vaccine intended to prevent the human papillomavirus (HPV) in females, is effective for men. But some men are signing up for the chance to take the drug.

Gay and bisexual men in San Francisco are asking their doctors for the vaccine with hopes it will prevent anal and penile cancer, also caused by HPV.

"The prevalence of anal cancer among gay and bisexual men is very high," says Jason Riggs, spokesman for the STOP AIDS Project. "So that's why some people are looking at this as a possible preventive cure for anal cancer and HPV that causes anal cancer."

Anal cancer occurs among gay and bisexual men at a rate 35 times higher than that of the general population. And it occurs more in those infected with HIV.

I've been reading her blog ever since Kristina Collins first wrote about her. I've been reading about her battle with leukemia -- for the second time -- and about the bone marrow transplant she received just recently. I read about her brother who became her bone marrow donor and her family and friends who became fierce supporters and cheerleaders for this young woman sure to beat cancer six years after she first conquered the disease.

Courtney Nicole did not win this battle. Just days ago, in the midst of her bone marrow transplant process, Courtney's body was infected with a bacteria that forced the removal of one leg. It turned out the bacteria was not confined to her leg -- it had invaded her entire body -- and it became clear that the fighting spirit of this woman was needed not here on Earth, but in the heavens above.

On November 14, 2006, Courtney earned her angel wings. In the words of her sister, "she will be young and beautiful forever and always." Indeed, she will.

Stomach cancer is hard to detect. It has no symptoms in its early stages, and there is no effective screening to detect its presence. So early detection and early treatment for this disease -- that attacks 800,000 people worldwide -- are hard to come by. In Taiwan, stomach cancer is the fifth most common cancer and the focus of study for researchers working to devise a method for detecting stomach cancer in its infancy.

A team of researchers at National Taiwan University Hospital have discovered a toxic factor -- GroES -- that causes stomach cancer. And they have discovered that a simple blood test will show either a positive or negative result for this substance, leading to immediate endoscopic exams for patients who may be at risk for stomach cancer. The test to identify GroES has already achieved a 65 percent accuracy rate.

Apparently, if the human body is infected with GroES, it produces antibodies to the factor and can cause chronic inflammation of the stomach, causing cells to rupture and proliferate. Long-term inflammation can cause stomach cancer. Researchers say about 45 percent of adults in Taiwan are infected with GroES -- and one percent will go on to develop stomach cancer.

Right now, patent applications are underway in the United States, Japan, and Taiwan. Once a kit is developed, a single drop of blood will be all it takes to determine the risk for stomach cancer.
