Can Lasers Help Prevent Skin Cancer?
Advances in laser technology continue to change the way dermatologists treat sun-damaged skin. While fractional laser resurfacing is widely recognized for improving skin texture, fine lines, and pigmentation, researchers are also studying whether it may help reduce the risk of certain precancerous skin changes. At DRS Skincare in Hamilton, Ontario, Dr. Rahul Shukla believes patients should have access to accurate, evidence-based information about emerging treatments. Although laser therapy is not currently a replacement for traditional skin cancer prevention, ongoing research suggests it may one day become a valuable part of a comprehensive skin health plan for selected patients.
Can fractional laser treatments prevent skin cancer?
At present, fractional laser treatments are not considered a standard method of preventing skin cancer. However, research has shown encouraging results, particularly in reducing actinic keratoses—rough, sun-damaged patches that can develop into squamous cell carcinoma. Some studies have also found a lower occurrence of certain non-melanoma skin cancers after laser treatment. While these findings are promising, larger clinical studies are still needed before lasers can be recommended specifically for skin cancer prevention.
Before and After Care
Which types of skin cancer have been studied?
Most research has focused on basal cell carcinoma, squamous cell carcinoma, and actinic keratoses, which are caused by years of ultraviolet (UV) exposure. Actinic keratoses are considered precancerous because some can progress to squamous cell carcinoma if left untreated. Current evidence has not shown that fractional laser treatments prevent melanoma, so patients should continue routine skin examinations and promptly have any suspicious or changing lesions evaluated by a qualified medical professional.
How do fractional lasers affect sun-damaged skin?
Fractional lasers create thousands of microscopic treatment zones that stimulate the skin’s natural healing response while leaving surrounding tissue intact. As the skin repairs itself, damaged cells are replaced with healthier tissue, collagen production increases, and overall skin quality improves. Researchers also believe these treatments may improve how aging skin responds to UV damage, helping reduce the accumulation of abnormal cells that contribute to precancerous changes.
What have clinical studies found so far?
Clinical research has produced encouraging early results. Studies involving older adults with extensive sun damage found fewer actinic keratoses and fewer non-melanoma skin cancers in laser-treated areas compared to untreated skin. Additional research involving patients with previous facial basal cell or squamous cell carcinoma also found lower recurrence rates following nonablative fractional laser treatments. Although these studies support further investigation, researchers agree that more extensive trials involving diverse patient populations are necessary before definitive recommendations can be made.

Should laser treatments replace sunscreen or regular skin examinations?
No. Daily use of broad-spectrum sunscreen, wearing protective clothing, limiting excessive sun exposure, and scheduling regular skin examinations remain the most effective ways to reduce skin cancer risk. Patients should also perform routine self-checks and seek prompt evaluation of any new, changing, bleeding, or non-healing spots. Fractional laser treatment should be viewed as a possible future addition to these proven preventive strategies rather than a substitute for them.
