Skin cancer develops when skin cells grow abnormally, and unprotected sun exposure or tanning bed use are common causes. Daily sunscreen use, protective clothing, and routine skin checks help reduce risk. When a dermatologist identifies suspicious spots early, they can recommend a prevention plan that is tailored to the patient’s skin type and medical history. Here is more information on skin cancer and how to prevent it:
What Is Skin Cancer?
Skin cancer occurs when abnormal skin cells grow uncontrollably. These cells form tumors, which may be benign or malignant depending on their cellular composition and growth rate. Three primary types of skin cancer are basal cell carcinoma, squamous cell carcinoma, and melanoma. Basal cell and squamous cell carcinomas are the most common forms, and they tend to grow slowly, making them more manageable when detected early. Melanoma spreads more aggressively than other forms, making early detection valuable.
Common symptoms include:
- A new or changing mole
- A sore that does not heal
- A patch of skin that changes in color or texture
What Causes It?
Ultraviolet (UV) radiation from the sun is the leading cause of skin cancer. Repeated UV exposure damages skin cell DNA, and tanning beds pose a comparable risk because they emit concentrated UV rays that accelerate this process. Genetics also plays a role, as patients with fair skin, light-colored eyes, or a family history of skin cancer face a higher likelihood of developing the disease.
Additional risk factors include a weakened immune system and a history of severe sunburns. Patients who live at high altitudes or near the equator face stronger UV exposure, which may increase their risk. Understanding personal risk factors is beneficial; it enables both the patient and dermatologist to develop a targeted prevention strategy.
How Is It Prevented?
Daily sunscreen application is an effective prevention method. Choose a broad-spectrum formula with an SPF of 30 or higher, and reapply regularly when outdoors. Protective clothing, wide-brimmed hats, and UV-blocking sunglasses add another layer of defense, particularly during peak sun hours, when UV radiation is most intense.
Tanning beds emit concentrated UV radiation, so avoid them. Seeking shade whenever possible further reduces cumulative UV exposure. Monthly self-exams are also recommended. Check for new or changing skin spots, and photograph anything unusual so that changes can be tracked systematically over time. Because no single measure provides complete protection, combining these habits creates a layered approach that helps lower overall risk.
How Can a Professional Help?
A dermatologist can perform a full-body skin exam, which allows them to spot abnormalities. Patients may undergo these exams once a year. Those with higher risk factors sometimes require more frequent visits to make sure any changes are identified promptly. If a dermatologist identifies a suspicious mole or lesion, they will perform a biopsy to determine whether it is cancerous. A dermatologist also offers personalized guidance, and this guidance is based on the patient’s skin type, medical history, and lifestyle.

Preventing skin cancer starts with daily habits like sunscreen use and shade-seeking, but professional guidance adds a layer of protection that self-care alone can’t provide. Regular skin exams catch changes early, when treatment is more effective. If you haven’t scheduled a skin check in the past year, book one now. A dermatologist will help improve your overall skin health.
