Signs of malignant moles?

Ask:

10 years ago, a mole appeared on the sole of my foot, but recently it has grown larger. I would like to ask if it is a malignant mole or not, how to identify it, doctor?

Doctor Tran Thi Thu, Dermatology Specialist, Medlatec General Hospital answered:

Congenital or acquired skin lesions such as freckles, moles, and skin pigmentation changes often appear on the human body. Most of these lesions are benign, however, in some cases these lesions can turn malignant. Therefore, it is necessary to monitor their progression.

Malignant moles are often asymmetrical in appearance. Benign moles have smooth, rounded borders, but atypical moles have irregular, tortuous, map-like borders. Instead of being brown or black, malignant moles are dark in some areas, light in others, black, brown, red, blue, or pigmented.

Common moles are less than 6mm in size, but moles larger than 6mm are considered to be high risk.

With moles at risk of malignancy, the time to change from small to large size is very short. In just a few months, the mole has increased several times. In addition, there are some other characteristics such as: ulceration, bleeding, rough surface, itching or pain.

In addition to identifying suspicious signs with the naked eye, people need to immediately go to reputable medical facilities to perform the necessary clinical tests to serve a definitive diagnosis.
