Using Scent To Detect Skin Cancer


The researchers also demonstrated that a nanotechnology-based sensor could reliably differentiate melanoma cells from normal skin cells.

Melanoma is a tumor affecting melanocytes, skin cells that produce the dark pigment that gives skin its color. The disease is responsible for about 75 percent of skin cancer deaths, with chances of survival directly related to how early the cancer is detected.

Current methods of detection typically rely on visual inspection of the skin, which is highly dependent on individual self-examination and clinical skill.
