Moles and skin tags are common skin growths that appear on the face, neck and body. They are usually removed for cosmetic or functional reasons (eg getting caught in clothing or cut during shaving). Rarely, these lesions may be cancerous.
A mole, also known as a nevus, is a common skin growth arising from pigmented skin cells called melanocytes. Moles can vary in color, size, and shape, and they are typically brown or black due to the presence of pigment (melanin). Moles can be formed from birth or can develop with age.While most moles are benign, it's important to monitor them for any changes in size, shape, color, or texture, as these changes could indicate the presence of skin cancer.
Skin tags are fleshy skin colored lesions containing collagen and blood vessels. They can commonly be found in parts of the body where the skin tends to rub together, such as:

Skin tags are caused when clumps of skin cells form folds in parts of the body that rub together. Common factors that are associated with skin tags are obesity, diabetes, and genetics [3]. Skin tags are non-cancerous, but some cancerous growths may resemble skin tags. Likewise, it is recommended to visit your doctor if you have any doubts or concerns.
Although they are typically harmless, skin tags can cause discomfort, such as itching, pain, or bleeding when they rub against clothing, jewelry, or other parts of your body.
Removal of moles and skin tags are commonly performed procedures in an aesthetic clinic. Prior to the procedure, a doctor’s consultation and assessment of the skin lesion will determine if it is likely to be benign or potentially cancerous. For skin lesions that are potentially cancerous, they will be sent to the laboratory for testing to determine the diagnosis and further treatment may be required.. [4].
Cryotherapy of moles or skin tags is not recommended due to the high recurrence rate.
