Photodynamic therapy (PDT) uses special medications combined with light to destroy cancer and precancer. This treatment is also called blue light therapy, red light therapy or phototherapy. PDT may be used to treat many types of cancer. This article will review PDT, its uses, what to expect during light therapy and phototherapy side effects. 49,53 This process causes a photochemical reaction and forms reactive free radicals and Singlet oxygen species which in turn lead to bacterial destruction (Figure 5). 49,53 Red light is known to penetrate deeper in tissues when compared to blue light. 50 It has been demonstrated that red light can affect the sebum secretion of sebaceous glands Shining near-infrared light on the tumor sites led to a reduction of fluorescence from cancer-tagged cells, indicating the treatment worked well as an anti-cancer strategy. Sato and his colleagues Red light therapy is also referred to as low-level laser therapy (LLLT) or photobiomodulation therapy. It is an increasingly sought-after non-invasive treatment which harnesses the power of red Red light is known to have a mitogenic effect based on its ability to activate cell division at certain spectral and dose ranges in vitro. 7 – 9 We are aware only of two studies on the effects of LLLT on cancer. 10, 11 Revazova demonstrated the acceleration of tumor growth by 633 nm laser irradiation at 3.5 J/cm 2 three times per week for 2 week Red light therapy is a wellness treatment that uses red LED light to treat cosmetic and medical skin conditions like acne, scars, and wrinkles. Cancer: Red light therapy has not been proven To start with the basics: blue light sits on the short-wave, high-energy end of the visible spectrum, close to the UV rays that can lead to provably harmful effects on the skin and retinas. Red light therapy is nontoxic, noninvasive, and considered safe for all skin types. You do not have to use any harsh topical substances or heat, both of which can irritate or burn the skin. Red light treatment does not use ultraviolet (UV) light, which has been linked to skin cancer. nb9xEX.
