Understanding precancerous skin lesions and skin cancer

Precancers and skin cancers can affect people of all ages and skin tones. Most develop from long-term exposure to ultraviolet (UV) radiation from the sun.

If you notice a changing mole or a spot that does not heal, it’s time for a full-body skin evaluation at Goodskin Dermatology.

What makes a lesion “precancerous?”

A lesion is considered precancerous when it consists of abnormal cells (dysplasia) that, while not cancerous, have a high potential to become cancerous if left untreated.

A common example of a precancerous lesion is actinic keratosis. These are rough, scaly patches that develop from long-term sun exposure, often appearing on sun-exposed areas.

How skin cancer develops

Skin cancer develops when DNA damage from UV radiation causes skin cells to grow uncontrollably. It can develop from untreated precancerous lesions or from new abnormal cell changes. Risk factors include:

  • Long-term sun exposure
  • Repeated sunburns
  • Tanning bed or lamp use
  • Family history
  • A weak immune system

At Goodskin Dermatology, our skilled team carefully examines suspicious spots and performs a skin biopsy, pathology testing and diagnosis when needed to confirm results.

Warning signs that should be evaluated

Changes in moles or spots

Watch for:

  • A mole that grows or changes shape
  • Uneven borders
  • Multiple colors in one spot
  • A new mole after age 30
  • Itching, bleeding or crusting

If you notice one or more of these changes in a skin growth, seek an immediate skin evaluation as they can be signs of cancer, including melanoma.

Non-healing, bleeding, or painful lesions

Get checked right away if you have:

  • A sore that does not heal
  • A spot the bleeds and returns
  • A crusted patch that keeps coming back
  • A shiny bump
  • Pain or tenderness in one area

These symptoms may indicate basal cell carcinoma, squamous cell carcinoma or another skin condition.

Types of precancers and skin cancers we treat

Precancerous and skin cancer conditions

Our board-certified dermatologists combine clinical excellence with compassionate care to diagnose and treat a wide range of precancerous skin lesions and skin cancers. Below are the most common conditions we evaluate and manage.

Squamous cell carcinoma is the second most commonly occurring type of skin cancer. It appears

Merkel Cell Carcinoma

Merkel cell carcinoma is a rare but very aggressive form of skin cancer. It commonly

Basal Cell Carcinoma

Basal cell carcinoma is the most common type of skin cancer and the most frequently

Actinic Keratoses

Actinic keratoses are precancerous growths on the skin caused by long term exposure to ultraviolet

How dermatologists diagnose skin cancer

Skin exams and Dermoscopy

At Goodskin Dermatology, our dermatologists perform detailed skin exams to improve accuracy and reduce unnecessary procedures.

They carefully evaluate your entire skin surface using a tool called a dermoscope to examine deeper details of suspicious lesions, moles or spots. Regular skin evaluations are important, especially if you have a personal or family history of skin cancer.

Biopsies and pathology

If a spot is concerning, your dermatologist may recommend a skin biopsy and pathology report.

During a biopsy:

  • A small piece of skin is removed
  • The sample is sent to the lab
  • Results show if cancer or precancer is present

If results are positive, our skilled dermatologists will answer any question you have, review treatment options and guide you every step of the way with confidence.

FAQs about precancers and skin cancer

Can precancerous lesions turn into skin cancer?

Yes. Some precancerous lesions, such as actinic keratosis, can turn into squamous cell carcinoma if they are not treated. Early treatment lowers this risk.

At Goodskin Dermatology, we recommend an annual full-body skin evaluation. However, more frequent screenings may be needed if:

  • You’ve had skin cancer before
  • Have many sun-damaged spots
  • Have a family history of skin cancer

After your initial appointment, we will recommend the right schedule for you.

Some skin cancers (e.g., basal cell carcinoma) grow slowly and rarely spread when treated early. Other types of skin cancer, like melanoma, can spread if not found quickly. Early detection through regular skin evaluations can improve outcomes.

If a skin biopsy confirms skin cancer or a high-risk precancer, your provider will review treatment options with you and determine the best approach. Treatment options may include:

  • In-office removal
  • Mohs surgery (for high-risk basal cell and squamous cell carcinomas on the face, scalp, hands or genitalia)
  • Topical treatment
  • Ongoing monitoring

Our skilled team will make sure you understand your care plan and feel confident about the next steps.
