Melanoma is a malignant tumor of melanocytes which are found predominantly in skin but also in the bowel and the eye. It is one of the rarer types of skin cancer but causes the majority of skin cancer related deaths. Despite many years of intensive laboratory and clinical research, the sole effective cure is surgical resection of the primary tumor before it achieves a thickness of greater than 1 mm. Minimizing exposure to sources of ultraviolet radiation (the sun and sunbeds), following sun protection measures and wearing sun protective clothing (long-sleeved shirts, long trousers, and broad-brimmed hats.) can offer protection. Using a sunscreen with an SPF rating of 30 or better on exposed areas has preventive effect.

A surgical procedure called lung reduction may improve symptoms for people with certain types of emphysema. During the procedure, part of the lung is cut out, giving healthy lung tissue more room to expand. Lung reduction may eliminate the need for supplemental oxygen and make it much easier for the person to breathe. Early studies show that it reduces the volume of the over-inflated lungs. Video footage from an actual surgery will be shown.

Many people have dental phobia.  It's not getting easier for dentists these days as they may have to give people more bad news, which could lead to an unwanted diagnosis of a serious disease. Diseases such as diabetes, HIV, blood cell disorders, bulimia, and oral cancer are being detected by dentists.  But early detection is a better alternative than none.
