Understanding Non-Cancerous Skin Spots — and When to Consult a Dermatologist
You look in the mirror and see a strange spot on your skin. Is this a new skin spot? Could this be skin cancer? How long has this been here? Your anxiety levels rise as you wonder if you should immediately book a dermatology appointment.
Take heart — not every skin spot or bump means something serious. Many non-cancerous (benign) skin lesions can appear over time, and while they may cause concern due to their appearance, they are usually harmless. Below is a guide to help you understand some common non-cancerous skin spots, their causes, and when to consult a dermatologist.
1. Lentigines (Age Spots, Brown Spots or Liver Spots)
Lentigines are flat, brown, or black spots that appear on areas frequently exposed to the sun, such as the face, hands, and shoulders. Often referred to as "age spots," "liver spots," or “brown spots,” these spots are a sign of sun damage, especially in older adults. They do not require treatment unless they become bothersome for cosmetic reasons, in which case topical treatments, chemical peels, or laser therapy can help lighten them.
2. Moles
Moles are common skin growths made up of pigmented cells called melanocytes. They can appear anywhere on the skin and are usually brown or black. Most moles are harmless, but it’s essential to monitor them for any changes, such as the ABCDEs, which can be signs of melanoma:
A - Asymmetry: One half of the mole or spot doesn't match the other half.
B - Border: Edges are irregular, ragged, notched, or blurred.
C - Color: The color is not uniform and may include shades of brown, black, tan, red, white, or blue.
D - Diameter: The spot is larger than 6mm (about the size of a pencil eraser), although melanomas can be smaller.
E - Evolving: The mole or spot changes in size, shape, color, or elevation, or a new symptom appears, such as itching or bleeding.
3. Seborrheic Keratoses
These waxy, wart-like growths can appear anywhere on the body, though they are more common on the back or chest. Seborrheic keratoses are typically brown, black, or tan and have a "stuck-on" appearance. They are non-cancerous and usually don't require treatment unless they become irritated or itchy. Cryotherapy (freezing), laser treatment, or minor surgery can remove them for cosmetic reasons.
4. Skin Tags
Skin tags are small, soft, flesh-colored growths that hang off the skin. They commonly develop in areas where the skin folds, such as the neck, armpits, and groin. Although they are benign, skin tags can become irritated by clothing or jewelry. They can be removed through minor procedures, including freezing (cryotherapy), cutting, or cauterization.
5. Angiomas
Angiomas are benign growths formed from small blood vessels. The most common type, cherry angiomas, appear as small red or purple spots on the skin, often increasing in number with age. While harmless, angiomas may bleed if scratched or cut. Removal is possible through laser therapy or other minor surgical techniques.
6. Warts
Warts are caused by the human papillomavirus (HPV) and appear as small, rough growths on the skin, typically on the hands or feet. While they are non-cancerous, warts can be unsightly and very contagious. Treatments like cryotherapy, salicylic acid, or laser therapy can help remove them fast, so they don’t spread within your body or to your loved ones you’re in close contact with.
7. Dermatofibromas
These firm, small, round bumps are usually reddish-brown and can appear on the legs or arms. Dermatofibromas are benign and result from minor skin injuries like insect bites or shaving nicks. They can be itchy or tender but are harmless. If they are bothersome, we can remove them surgically.
8. Cysts
Cysts are sac-like pockets under the skin that contain fluid, pus, or other material. They can vary in size and usually develop slowly. Common types include sebaceous cysts, which arise from blocked sebaceous glands and contain oily sebum, and epidermoid cysts, which originate from skin cells and are filled with keratin. Although benign, they can become painful or infected. In such cases, we can drain or remove the cyst.
9. Lipomas
Lipomas are soft, fatty lumps that grow slowly under the skin and are typically found on the neck, shoulders, back, or arms. They are non-cancerous and usually painless, though they can be removed surgically if they become large or uncomfortable.
When to Consult a Dermatologist
While most of these skin conditions are harmless, it’s essential to stay vigilant. If you notice any changes in size, shape, color, or if a growth becomes painful or starts to bleed, schedule a consultation right away. Early detection of any skin irregularity, whether benign or malignant, is key to maintaining skin health.
