It's not surprising marathon runners face an increased risk of skin cancer due to long-term sun exposure. What's surprising is that so many are not taking measures to protect themselves from the sun's damaging rays.

A team of Austrian researchers, all of them dermatologists, became interested in studying long-distance runners when they realized they had collectively treated eight ultra-marathon runners with malignant skin cancer over a period of 10 years. All researchers are themselves enthusiastic runners, and two of them participate in marathons. The topic was near and dear to their hearts.

Research was conducted on white runners, so it is unclear if the findings -- listed below -- apply to black runners.

• Only 56 percent of runners in the study reported wearing sunscreen. Most were unaware of the increased risk to their skin -- and even the running researchers report it is good to be reminded to wear the right gear and regularly use sunscreen

• Many runners race with a lot of skin exposed. And sometimes training clothing covers different areas than racing clothing. Shoulders that are covered during training may be exposed during the long hours of a marathon. During triathlons, most wear a bathing suit for the duration of the event, leaving most skin susceptible to burning. Runners can lower their risk by training during morning and evening hours and wearing water-resistant sunscreen. They can wear clothing made of new fabrics that screen harmful ultraviolet rays.

• It's possible that endurance athletes may have suppressed immune systems caused by repeated tissue damage, leaving them more vulnerable to skin cancer.

While some marathon runners take pride in a bronzed skin -- proof they are running in the elements -- researchers hope runners will consider the risk they face. In some races, volunteers offer to quickly apple sunscreen on athletes who don't want to lose precious seconds as they race for the finish line. It's a start.

Monday night is Courage Night, hosted by the Young Survival Coalition (YSC), national sorority Zeta Tau Alpha (ZTA), and Lifetime television. It's a night when Lifetime's Original Movie Why I Wore Lipstick to My Mastectomy will air, when crowds will gather in communities and on college campuses across the nation for special screenings and viewing parties of the movie that brings glaring attention to the issue of breast cancer.

Courage Night was created in 2004 by Geralyn Lucas, author of the book Why I Wore Lipstick to My Mastectomy, as an evening of celebration in honor of Breast Cancer Awareness Month. It was also a celebration of the publication of her then-new book.

Lucas, diagnosed with breast cancer at age 27, recounts in her memoir every step of her cancer journey, including her bold application of red lipstick just before her mastectomy. She knew from the day she was diagnosed she would speak out to help others, to raise awareness, to make a difference. Now 39, a mother of two, and an executive for Lifetime, Lucas is still making waves. And Courage Night lives on.

Courage Night has grown into a national grassroots event that honors breast cancer survivors and those lost to the disease. Event fundraising will benefit YSC -- the only organization dedicated to the special issues of young breast cancer survivors.

Why I Wore Lipstick to My Mastectomy, starring actress Sarah Chalke, will air Monday, October 23 at 9:00 PM.

Katie Couric spent her summer traveling the country visiting with future CBS news fans and raising money for cancer awareness. Couric, whose husband Jay Monahan died of colon cancer in 1998 at the age of 42, has become a prominent spokesperson for colon cancer awareness. She underwent a colonoscopy on-air in March 2000 and inspired many others to get checked. In October 2005, in honor of Breast Cancer Awareness Month, Couric broadcast her own mammogram on the Today Show in hopes of motivating women everywhere to get schedule their own mammograms. Her influence on both cancer fronts -- known as the Couric Effect -- demonstrates the fact that one powerful person can draw much attention to important causes. And perhaps her influence -- soon to arrive on television screens everywhere -- will continue as she takes the driver's seat on the CBS Evening News beginning September 5 at 6:30 PM.

On her second day of work in her new job, Couric will interview President Bush at the White House as part of a primetime special. Other story plans include digging deeper into the stories of the day and answering questions viewers might have on all topics. Hopefully, cancer issues will continue to take priority in Couric's life so that we all may benefit from her advocacy.

New CBS Evening News anchor Katie Couric is on a six cities tour to connect with viewers and promote colon cancer awareness to encourage colon cancer screenings. 

On Tuesday, Couric was in Dallas to attend a benefit luncheon for the American Cancer Society. According to reports, most of her talk was about her husband Jay Monahan's colon cancer diagnosis, treatment and death. She is quoted as saying, "He felt invincible, immortal, before doctors found that he not only had colon cancer but also that it was at an advanced stage, taking over his liver." She described Monahan's last day and the moment of his death. There were many tears in the audience.

Couric expressed the feelings many cancer patients and their families feel when the diagnosis of cancer is given. "Suddenly you need to have a medical degree to deal with all the options," she said. One of the reasons she worked to open The Jay Monahan Center for Gastrointestinal Health, named in Monahan's honor, was because she wanted to create the kind of center for others that both her and her husband would have appreciated when he was first diagnosed with cancer. 

"It was a very lonely and isolating experience and very harrowing to go from one specialist to another. Having this comprehensive center full of compassionate caregivers all under one roof would have been a wonderful place for us to go. The opening was a bittersweet occasion, but the center is going to be incredibly helpful to thousands of families and what can be better than that?"

Couric began her six cities tour in Tampa, Florida. Today she was in Dallas and plans stops in Minneapolis/St. Paul, Denver, San Diego and San Francisco. She takes over for CBS Evening News Bob Schieffer on September 5.

Kaycee Marie Macdonald, now 12 months old, was diagnosed with neuroblastoma in May. So far, Kaycee has had 2 operations, one because her kidneys were failing and another to implant a tube in her chest for chemotherapy drugs. Every three weeks, she undergoes three days of chemotherapy. Friday, July 7, was just another day at the Jimmy Fund Clinic for Kaycee and her mother Kerri Macdonald, as Kaycee would be getting chemotherapy.

But that day would be different. As Kerri said in a CBS4 Boston television interview, "It's nice when the adrenaline rush is because of something happy and not for fear." The adrenaline rush of happy had to do with a surprise visit from Sheryl Crow. In town to perform at Fenway Park with Dave Matthews that night, Crow stopped in to visit with children being treated for cancer at the clinic. There she met baby Kaycee, where both cuddled and spent a little time together. For Kaycee's mother, it is a bright moment that she can hang onto in memory for the continued dark journey of worry and concern.

Not only that, but Kaycee, by being featured on the evening news, has captured the hearts of a whole new large family of viewers who will keep her in their thoughts and prayers -- and perhaps help the family out with donations as they struggle to get the care Kaycee needs to survive her cancer. With the visit from Crow, Kerri has started blogging about Kaycee. Kaycee is such a sweet little girl. You can watch the CBS4 Boston television interview video here.

According to Medline Plus, neuroblastoma is a form of cancer that occurs in infants and young children. It is rarely found in children older than 10 years. The cells of this cancer usually resemble very primitive developing nerve cells found in an embryo or fetus. The term neuro indicates nerves, while blastoma refers to a cancer that affects immature or developing cells.
