What are precancers?
Precancers, or precancerous lesions, are abnormal changes in skin cells that have the potential to develop into cancer over time. Though the cells aren’t currently cancerous, they have the potential to be over time if not treated.
A common type of skin precancer is actinic keratosis, which often appears on sun-exposed areas like the face, ears, scalp, and hands. Identifying and treating precancers early can help prevent skin cancer, especially squamous cell carcinoma.
What are the signs of precancers?
Precancers can vary in appearance but often show up as rough, scaly patches or dry, crusty spots on the skin. They may be red, pink, brown, or flesh-toned and feel tender, itchy, or irritated.
Unlike a harmless dry patch, precancers tend to persist, grow slowly, or return after flaking off. Some may bleed or develop a sore that doesn’t heal. Any new or changing spots should be checked by a dermatologist since they can look different on each person.

Are precancerous lesions preventable?
Yes — most precancers are preventable with consistent sun protection and healthy skin habits. Wear broad-spectrum sunscreen daily, avoid tanning beds, and seek shade during peak sun hours to reduce UV damage that can lead to precancerous changes.
In addition, protective clothing and wide-brimmed hats are simple, effective tools for reducing risk. Regular skin checks at home and with a dermatologist can also help detect precancers early.
However, many precancers that arise are the product of sun exposure from childhood, adolescence or early adulthood.
How are precancers treated?
Your dermatologist conducts a thorough skin exam and may take a small tissue sample to rule out skin cancer with the use of a microscope. If they detect precancerous cells, there are a few options for treatment.
Cryotherapy
This quick, in-office treatment involves freezing the precancerous lesion with liquid nitrogen. The frozen cells die and usually fall off within a few days to weeks.
Photodynamic therapy (PDT)
This noninvasive treatment uses a special light-sensitive medication applied to your skin. After activating the area with a specific light source, the precancerous cells are destroyed without harming surrounding tissue.
Topical Chemotherapy
Safe and effective topical cream forms of mild chemotherapy agents will encouraging your immune system to target abnormal cells.
Mild surgical options exist for precancer treatment as well. Your dermatologist recommends the best approach based on the type, size, and location of the lesion.
