Does Laser Hair Removal Cause Cancer?

It has been used for decades, and studies have not found evidence of long-term cancer risk. As with any light-based treatment, safety depends on proper settings, trained operators and avoiding moles and suspicious spots.

It uses light, which is technically a form of radiation, but it is non-ionizing. That is different from X-rays, which are ionizing and can damage DNA in cells.

Moles are usually avoided or covered, because the laser targets pigment and can change how a mole looks. Have any changing or unusual mole checked by a doctor before you start.

Talk to your oncologist or doctor first. Treatments and medications can make skin more sensitive, and timing depends on your history. Bring their advice to your consultation.

Most providers ask you to wait, because there is little research in pregnancy and skin can change during that time. Ask your doctor, and plan to resume after pregnancy.

Redness and mild swelling are common for a few hours. Less often, burns, blisters or pigment changes can occur. Sun exposure before treatment and the wrong settings make these more likely.
