Cell lifespan is limited by telomeres, DNA sequences that cap chromosomes and control the number of times a cell may be copied.

Vacationing at the shore led to a 5 percent increase in nevi (more commonly called "moles") among 7-year-old children, according to a paper published in Cancer Epidemiology, Biomarkers and Prevention, a journal of the American Association for Cancer Research.

University of Michigan Health System researchers have published new data to help answer two dreaded questions: "Is it cancer?" and "What type of treatment should I have?"

By playing it safe and using a two-pronged attack, a novel designer molecule fights malignant melanoma. It was created and tested by an international team of researchers led by the University of Bonn.

In a proportion of human solid tumors, in particular melanomas (a form of skin cancer that is often resistant to chemotherapy), inappropriate activation of the MEK/ERK signaling pathway as a result of mutations in the B-RAF gene promotes tumor cell growth and survival.

Inflammation, a frontline defense against infection or disease, can help nurture skin cancer, researchers have found.

Melanoma patients infused with a special type of tumor-fighting T cell are more likely to survive without relapse, suggests a new study by researchers in France. Their report will be published online on October 20 in the Journal of Experimental Medicine.

A new study indicates that educational literature can influence young women's use of indoor tanning, not by raising their fear of skin cancer but by changing their attitudes about indoor tanning and promoting healthier alternatives for changing appearance. The study is published in the December 1, 2008 issue of CANCER, a peer-reviewed journal of the American Cancer Society.

A new analysis indicates an association between a gene involved in vitamin D metabolism and skin cancer.

Researchers at the NYU Cancer Institute and the Ronald O. Perelman Department of Dermatology have identified mebendazole, a drug used globally to treat parasitic infections, as a novel investigational agent for the treatment of chemotherapy-resistant malignant melanoma.

We are continuously bombarded with messages about the dangers of too much sun and the increased risk of melanoma (the less common and deadliest form of skin cancer), but are these dangers real, or is staying out of the sun causing us more harm than good?

University of Rochester Medical Center researchers found a new protein produced excessively in malignant melanoma, a discovery that is particularly relevant as skin cancer rates climb dramatically among young women.
