Lasers are used to treat cancer in several different ways. Their high-intensity light can be used to shrink or destroy tumors or precancerous growths. Lasers are most commonly used to treat superficial cancers (cancers on the surface of the body or the lining of internal organs) such as basal-cell skin cancer and the very early stages of some cancers, such as cervical, penile, vaginal, vulvar ...
It has also undergone Phase III clinical trials (USA) for the treatment of cutaneous non-melanoma skin cancer. [3] The chromophore of BPD-MA has a red-shifted and intensified long-wavelength absorption maxima at approximately 690 nm. Tissue penetration by light at this wavelength is 50% greater than that achieved for Photofrin (λmax. = 630 nm ...
Photorejuvenation is a skin treatment that uses lasers, intense pulsed light, or photodynamic therapy to treat skin conditions and remove effects of photoaging such as wrinkles, spots, and textures. The process induces controlled wounds to the skin. This prompts the skin to heal itself, by creating new cells.
Laser radiation being delivered via a fiber for photodynamic therapy to treat cancer. A 40-watt CO 2 laser with applications in ENT, gynecology, dermatology, oral surgery, and podiatry. Laser medicine is the use of lasers in medical diagnosis, treatments, or therapies, such as laser photodynamic therapy, [1] photorejuvenation, and laser surgery.
Light therapy treatments for the skin usually involve exposure to ultraviolet light. [2] The exposures can be to a small area of the skin or over the whole body surface, as in a tanning bed . The most common treatment is with narrowband UVB, which has a wavelength of approximately 311–313 nanometers.
Treatment of conjunctival SCC is usually surgical excision followed by cryotherapy. [1] After this procedure, Conjunctival SCC can recur 8–40% of the time. [1] Radiation treatment, topical Mitomycin C, and removal of the contents of the orbit, or exenteration, are other methods of treatment. [1]

Mohs surgery is the gold standard method for obtaining complete margin control during removal of a skin cancer (complete circumferential peripheral and deep margin assessment - CCPDMA) using frozen section histology. [1] CCPDMA or Mohs surgery allows for the removal of a skin cancer with very narrow surgical margin and a high cure rate.
