Device for early diagnosis of melanoma to detect the formation of tumors

Early diagnosis of melanoma, the most aggressive skin cancer, is important because melanoma is rapidly spreading throughout the body. Now researchers at the University of Missouri came close to identifying cancer at the cellular level, before the formation of tumors.

Commercial production of the device, which measures the melanoma using photoacoustics and laser-induced ultrasound, will soon be available to scholars and academic cancer research.

"Based on a small sample of blood our device will provide early detection of aggressive cancer or melanoma," – said John Viator, an associate professor of biomedical engineering and dermatology.

Currently, doctors use CT or MRI for the diagnosis of cancer. Photoacoustic device guides the laser light into the blood, and melanin cancer cells absorb it. These cancer cells are rapidly heated and expanded, and then give off heat and glow.

The device finds cancer at the cellular level, long before the formation of tumors. After two or three years, new diagnostic method is approved, and its cost will be several hundred dollars that will be cheaper than MRI and CT.

"We try to provide faster and cheaper method of screening, which ultimately will be better for the patient and the doctor", – says John Viator.
