A case study published by dermatologists at the University of Portland, in the United States, identified the smallest skin cancer in the world. Measuring just 0.65 mm, half the thickness of a thick hair, the melanoma was virtually invisible to the naked eye. The smallest case documented so far was 0.9 mm.
The article, published in Dermatology Practical & Conceptual in January of this year, stated that the cancer was found in the face of a 61-year-old woman. In addition to the record, the discovery is important for advancing techniques for detecting skin cancers at an early stage.
“Fast detection of melanoma is the most important method to fight the disease. To make the diagnosis, we need to use different tactics”, say the researchers in the article.

The discovery was possible from a self-examination made by the patient, who found the small spot. To detect cancer, a combination of imaging and molecular tests was performed.
The woman had no history of skin cancer and doctors say the disease developed from overexposure to the sun. The melanoma and surrounding skin were removed in minor surgery.
