Skin growths are common and can appear at various stages of life for different reasons. While many growths are benign, others may require closer monitoring or specific care. Recognizing the key characteristics of common skin growths can help individuals work with a dermatologist to address these concerns effectively.
1. Moles
Moles are clusters of pigmented skin cells that manifest on the surface of the skin. They can vary in color from brown to pink and may appear flat or raised. Most people have several moles on their body, and they typically develop during childhood or early adulthood. While moles are usually harmless, they can change in appearance over time.
When to Seek Medical Attention
It’s important to monitor moles for changes in size, shape, color, or texture. A mole displaying irregular borders, uneven pigmentation, or an increase in size may warrant an evaluation by a dermatologist. Such changes could indicate a potential risk of malignancy, such as melanoma.
2. Warts
Warts are small, rough, and raised growths caused by certain strains of the human papillomavirus (HPV). They typically appear on hands, feet, or other areas of frequent contact and vary in appearance based on their type. Warts are contagious and can spread through direct skin contact or shared surfaces.
Types of Warts
- Common Warts: Typically found on hands or fingers, these have a pebble-like texture.
- Plantar Warts: Located on the soles of the feet, they can feel painful when walking due to pressure.
- Flat Warts: Smaller and smoother than other types, most often appearing on the face, arms, or legs.
- Filiform Warts: Thin and thread-like, commonly appearing on or around the mouth and nose.
Treatment Options
Many warts resolve naturally over time, but treatments can speed up the process or manage discomfort. Over-the-counter remedies like salicylic acid-based solutions are a common first step. For stubborn warts, dermatologists may recommend cryotherapy (freezing the wart with liquid nitrogen), laser treatment, or surgical removal.
3. Skin Tags
Skin tags are soft, flesh-colored growths that typically develop in areas where skin rubs together, such as the neck, armpits, or under the breasts. These harmless growths are small, often appearing as tiny flaps of skin, and are not associated with any serious health conditions.
The Causes of Skin Tags
Factors contributing to their development include genetics, weight-related skin friction, age, or hormonal changes like pregnancy. While they are benign and usually painless, skin tags can sometimes become irritated by clothing or jewelry.
4. Keratosis Pilaris
Keratosis pilaris, often known as “chicken skin,” is a common skin condition characterized by small, rough bumps on the surface of the skin. These bumps usually appear on the arms, thighs, buttocks, or cheeks. Although harmless, they can make skin feel uneven.
Triggers of Keratosis Pilaris
Keratosis pilaris occurs when keratin, a protein that protects skin, builds up and blocks the hair follicles. This condition often worsens during colder months when the skin tends to dry out. It is more common in individuals with dry skin or certain genetic predispositions.
Take the Next Steps With a Dermatologist
Many growths, such as moles, warts, skin tags, and keratosis pilaris, are typically non-threatening. Being aware of their characteristics allows you to take thoughtful care of your skin and identify when professional attention might be needed. For specific concerns or personalized advice, consulting a dermatologist is always recommended.
