Australian scientists unveiled an “imaging gun” Tuesday they hope will reduce skin cancer deaths by allowing doctors to detect melanomas instantly.

Sunny Australia has the world’s highest skin cancer rate and around 1,000 Australians die each year from melanoma skin tumours.

The “Solarscan” is placed on a patient’s skin and takes an image of the potential melanoma spot. It then reads the image and compares it with a database of skin tumours to determine whether it is cancerous.
