The subtitle: contrary view on behal of patients” speaks for itself.  A. Bernard Ackerman is a distinguished dermatologist, world-renowned for his knowledge of skin cancer. When such a doyen in the field of melanoma presents a treatise questioning the evidence that sun is a causative factor in the development of melanoma and suggesting that there is no substantiating evidence for an increase in the incidence of melanoma worldwide, one must take notice. An well-researched easy read with lots of interesting information.
