Both moles and warts are some of the most common skin conditions seen in dermatology. Although both are small skin growths, the conditions differ in their origins, appearance, and potential health implications. In this article, we will explore what the two conditions are and how they differ, helping you to better understand your skin and any changes it might go through.
What are warts?
Warts are small, hard skin growths that can develop across the body, most commonly on the hands, feet, and even the face. These growths can occur alone or in a cluster, and usually appear as rough, skin-coloured bumps, without any hair.
What causes warts?
Warts are caused by the viral infection, human papillomavirus (HPV). Over 100 types of HPV exist, and different strains are responsible for different types of warts. The virus encourages a protein called keratin to overproduce in the top layer of the skin, which eventually forms into the wart.
Because warts are caused by an infection, they are considered contagious, spreading through direct skin contact or in moist environments like swimming pools.
Are warts a health risk?
Generally, warts are harmless to your health and carry little health risk. However, they can be bothersome or potentially painful, especially if they are located on sensitive areas such as the feet. Warts can disappear on their own, but some people decide to get them removed with a dermatologist if they are a nuisance.
What are moles?
Moles are small growths that are usually round or oval, and may be flat, raised, hairy, or smooth. Moles are generally darker than warts, such as a dark brown or black colour, and also tend to be more uniform than warts.
Whilst warts tend to occur in certain areas, especially the feet, face, hands, and arms, moles can occur virtually anywhere on the body.
What causes moles?
Moles form when pigment-producing cells known as melanocytes grow in clusters. Melanocytes are responsible for giving skin its natural colour. Whereas warts form from a virus, moles normally form due to genetics, but other factors like age and sun exposure can increase the likelihood of developing moles.
Unlike warts, moles are not contagious.
Are moles dangerous?
The vast majority of moles are harmless. However, moles can develop into something more sinister, such as melanoma, a type of skin cancer. This mainly occurs when a mole has been exposed to too much ultraviolet radiation, but sometimes, there is no obvious cause.
It’s important to talk to a dermatologist if you notice any new moles or developments to your moles, including changes to size, shape, texture or colour, as well as any symptoms such as itching or bleeding.
Some people get moles removed if they pose a health risk such as skin cancer, or for aesthetic or comfort reasons.
