People who use tanning beds likely face the same risk of deadly skin cancer as those who lay out in the sun, according to a report in Pigment Cell Melanoma Research. <br> <br> * And taking part in a support group can help relieve the stress of the illness for both mesothelioma patients and their families, according to a study in the September 12 issue of the European Journal of Cancer Care.
