Are moles a cause for concern?
Moles or Nevi are growths on the skin which appear as small brown or black spots. They usually appear in the first 2 decades of life. Moles are usually harmless, but they may become cancerous hence it is important to monitor them. Malignant melanoma is the predominant cancerous change in moles. Risk is high if the mole is congenital and is greater than 8 inches in diameter, if it first appears after the age of 20 years, if its is larger than a pencil eraser [1/4 inch], if it is irregular in shape and color [dyplastic] and finally if they are in a large number [greater than 50].It is best to seek medical advice if a new mole appears after the age of 20 yrs or if the mole shows burning, itching, oozing, bleeding, scaling, crust formation, change in color, size, shape and elevation.
