As Skin Cancer Awareness Month winds down, I find myself hoping you have learned a thing or two about a disease that is far more common than we tend to believe, a diseases that in some cases is downright deadly.

The month of May will soon drift away. Skin cancer will not -- unless of course we make huge, swift strides in prevention. Until this happens, though, the best we can do is be vigilant about early detection. I have an idea. Well, an idea I'm borrowing from The Archives of Dermatology.

The idea: photography. Studies show patients who use photographs of their own skin for reference are better able to detect skin changes while conducting self-examinations.

There is no doubt that the new cervical cancer vaccine -- Gardasil -- is revolutionary. But writer Peter Sprigg, vice president for policy at the Family Research Council, shared yesterday on the washingtonpost.com that the public should consider two cautions when digesting the news of this breakthrough medical advance. He urges us, first, to understand that the vaccine is not 100 percent effective. It is 100 percent effective for the strains of human papillomavirus (HPV) it targets -- but it leaves 30 percent of HPV strains that cause cervical cancer untouched. And it does not prevent all cases of genital warts either. So it is largely effective. But it does not completely eradicate the disease.

Sprigg also believes that parents should determine whether or not their young girls get the vaccine -- that it should not be mandatory. Mandating the vaccine might be in order if HPV was spread through blood or casual contact. But it is not -- it is spread by sexual contact. And families of young girls might best address this issue through education on behavioral issues alone, without interference from the government.

The wonder of the cervical cancer vaccine is not in question by this writer and the council he represents. But there is often a full picture that lingers behind good news and sensational headlines. And Peter Sprigg offers his take on what he believes lingers behind.

Pat Bohman is a grateful mother. Her daughter Kelsey, who was treated at Children's Hospital in Denver for leukemia, has made it through the battle. During the Christmas season of 2002, Pat thought about the children still in the hospital fighting cancer and she wanted to make them gifts. She came up with idea for the Marshmallow Launcher -- a kind of blow gun that shoots marshmallows. The children make a poster target by drawing pictures of cancer cells, the poster gets put on the wall and then the kids shoot marshmallows through a pipe-like device at the target. Marshmallow Launchers are a big hit with the kids at the hospital.

According to Bohman, the marshmallow launchers were created for the kids in isolation on the oncology unit at The Children's Hospital as a means to relieve tension, while away the long hours in isolation, and have some fun in the midst of very difficult circumstances.

But it turned out that the Marshmallow Launcher serves a medical purpose. As a respiratory device, it helps a child strengthen lung capacity. Much more fun than pinwheels and bubbles. Bohman is even thinking about adding a flow meter to the launcher as a way to measure lung capacity progress. But for the kids, it's just pure fun.

In addition, when Bohman finds out another family in her area has a child who has been diagnosed with cancer, she sets up a booth to sell the launchers. The young and young-at-heart are drawn to the fun of the Marshmallow Launcher. It has been suggested that some adults use them for interoffice communications. If you would like a Marshmallow Launcher of your own, you can visit Kelsey's Kids website where you can purchase one. Bohman makes them in the basement of her home. The profits are donated to the hospital that helped her daughter fight against cancer and win.
