“Reviews of studies on UVB, both narrowband and broadband, do not indicate any increased risk of nonmelanoma skin cancer or melanoma.”

“In this large study, with follow-up of up to 22 years from first treatment with NB-UVB, we did not find any definite association between NB-UVB treatment and BCC, SCC or melanoma skin cancer.”
“No increased risk of skin cancer was evidenced in the four studies specifically assessing the potential carcinogenic risk of NB-UVB.”

“There were no statistically significant differences between the nbUVB and control groups. Thus, nbUVB phototherapy using TL-01 lamps seems to be a safe therapeutic modality for patients with skin phototypes III-V.”

“Dr. Lebwohl says. “At least so far, it appears that narrowband UVB does not contribute to skin cancer. Nonetheless, in patients who are cancer prone, we are cautious about the use of phototherapy.”
“Thus, the present study does not provide evidence for an increased skin cancer risk for patients treated with either broadband or narrowband UVB phototherapy”

“(UVB-Narrowband) Phototherapy is safe and easy to perform. Although complications can include sunburn, we are not seeing any skin cancers, melanoma or non-melanoma. Vitiligo is probably protective for melanoma.”
“Despite concerns over the carcinogenic potential of ultraviolet radiation, most studies have not found an increased risk of non-melanoma or melanoma skin cancer in patients treated with ultraviolet B (broadband and narrowband) and ultraviolet A1 phototherapy.”
