Moles and skin tags are different types of skin lesions. They are very common and generally are noncancerous.



Moles are nothing but some growths on your skin. They are usually black or brown in color. They may show up at any place on the skin. They may appear alone or in groups. Most moles are seen during early childhood and before the first 30 years. Moles are common in adulthood as well.

With the passing time, moles start changing slowly and become raised in appearance. They also change colors. Hairs are also seen on the moles very often. Some of the moles can disappear after some time.

Causes of a mole

If cells present in the skin start to grow in a cluster instead of spreading throughout the skin, then moles appear. The cells in the skin are known as melanocytes. These are the cells which create the pigments that provide the natural color of the skin. Under exposure to the sun, the moles may look darker. It happens especially during pregnancy or teen years.

Types of moles

The moles that show up at birth are known as congenital nevi. It is seen in the case of one in hundred people. These moles can be dangerous as they are more likely to be cancerous in comparison to the moles that show up after birth.

The moles which are bigger than the average moles are known as dysplastic nevi. There are bigger than a pencil eraser and irregular in shape. These moles often have dark brown centers and uneven color. They also have uneven and lighter edges. It is possible to have more than 100 dysplastic nevi moles. They have a higher risk of causing melanoma, which is a type of skin cancer. If you find any changes in such a mole, you should go to a dermatologist to ensure that it’s not skin cancer.

The mole may be cancerous or noncancerous and this is very important to consult your doctor at an early stage to find out about the possibility of it being cancerous.

Treatment of moles

You need to consult with your dermatologist about the moles. If your dermatologist thinks that the mole should be evaluated and removed, then the doctor will take a small tissue from the mole to evaluate whether it is cancerous or not. This is known as biopsy and the section of the mole tissue is examined under a microscope. It’s a very simple procedure and effective. If the doctor thinks that there is a  possibility of the mole becoming cancerous, he/she will remove the mole using surgery to remove the possibility of cancer in the future.

Skin tag

A skin tag is a hanging small flap of tissue. This tissue hangs off with the help of a connecting stalk. They are not dangerous. These are mostly seen on the neck, back, chest, arm pits, groin area and under the breasts. These are mostly seen in the case of women and in elderly people.

Generally, they do not cause any pain. However, they may cause irritation if anything rubs them.
