FRIDAY, April 25 (HealthDay News) -- Though shrouded in secrecy during his lifetime, historians have gone to great lengths to posthumously chronicle the mysterious circumstances surrounding the health of Franklin Delano Roosevelt, the 32nd president of the United States.

That he suffered from both polio and heart disease is now well-documented. But a new study suggests that he may also have had -- and possibly even died from -- melanoma.

TUESDAY, April 22 (HealthDay News) -- Skin lesions larger than six millimeters in diameter are more likely than smaller lesions to be melanoma skin cancer, a new study suggests.

The finding supports the current widespread use of diameter guidelines to screen for melanoma, researchers say.

This "ABCDE" screening method is based on five features characteristic of melanoma: asymmetry, border irregularity, color variegation, diameter larger than six millimeters, and changes in a lesion.

TUESDAY, Feb. 19 (HealthDay News) -- Combining periodic infusions of antibodies with a widely used cancer vaccine appears to be more effective and less harsh with melanoma and advanced ovarian cancer patients than using either treatment on its own, a new study shows. Besides demonstrating the potential usefulness of a vaccine-and-antibody approach, the study -- published online in this week's issue of the the Proceedings of the National Academy of Sciences -- suggests a way of refining treatments even further, based on the biological events that antibody treatment sets in motion.
