Precancerous Spots

Precancerous spots, also known as precancerous lesions or dysplastic nevi, are abnormal growths on the skin. It is important to detect and treat these spots early, as they can be a sign of skin cancer or may eventually become cancer if left untreated.

What Do Precancerous Spots Look Like?

Precancerous spots can appear on any part of the body but are most commonly found on areas of the skin that have been exposed to the sun, such as the face, neck, and arms. These spots can vary in size, shape, and color and may look similar to moles or other types of skin growths.

It is important to have any unusual or changing spots on the skin checked by a dermatologist as soon as possible, as early detection and treatment can greatly improve the chances of a successful outcome.

Preventing Precancerous Spots

There are several steps that individuals can take to reduce their risk of developing precancerous spots:

  1. Wear sunscreen: Sun exposure is a major risk factor for precancerous spots and skin cancer. Wearing sunscreen with an SPF of at least 30 and applying it regularly can help protect the skin from harmful UV rays.
  2. Avoid prolonged sun exposure: Limit the amount of time you spend in the sun, especially between 10 am and 4 pm when the sun’s rays are the strongest.
  3. Wear protective clothing: Wear long-sleeved shirts, pants, and wide-brimmed hats to protect your skin from the sun.
  4. Avoid tanning beds: The UV rays from tanning beds can damage the skin and increase the risk of precancerous spots and skin cancer.
  5. Check your skin regularly: Perform a self-examination of your skin at least once a month to look for any unusual or changing spots. If you notice any changes, see a dermatologist as soon as possible.
  6. Schedule annual skin exams: Regular check-ups with a dermatologist are important for the early detection and treatment of precancerous spots, skin cancer, and other skin conditions.

Treatments for Precancerous Spots

There are several treatment options available for precancerous spots, and the most appropriate treatment will depend on the size, location, and type of precancerous spot, as well as the individual’s overall health and preferences. Some common treatment options for precancerous spots include:


This involves freezing the precancerous spot using liquid nitrogen. Cryosurgery is often used for smaller precancerous spots.


This involves cutting out the precancerous spot and surrounding tissue using a scalpel or laser. Excision is often used for larger precancerous spots and may require stitches to close the wound.

Photodynamic Therapy

This involves applying a photosensitizing agent to the precancerous spot and exposing it to a special light source to kill the abnormal cells. Photodynamic therapy is often used for precancerous spots on the face or other areas difficult to treat with other methods.

Laser Therapy

This involves using a laser to remove the precancerous spot and surrounding tissue. Laser therapy is often used for small precancerous spots.

Topical Medications

These are creams, ointments, or gels that are applied directly to the skin to kill abnormal cells. Topical medications may be used for small or early-stage precancerous spots.
