- The technique works by generating localized heat from light exposure, which selectively kills cancer cells while sparing normal tissues.
- Experts emphasize the need for further clinical trials to fully validate safety, dosage, and effectiveness across different cancer types.
- If successful, LED-based phototherapy could soon become a mainstream tool in the fight against cancer, complementing or even replacing some existing therapies.
In what is seen as scientific breakthrough, the American researchers have unveiled a promising photothermal therapy using near-infrared LED light to destroy cancer cells while leaving surrounding healthy tissue unharmed.
Unlike traditional chemotherapy or radiation, this approach relies on inexpensive, widely available LED systems instead of specialized lasers, reducing collateral damage and offering a safer, less invasive alternative.
The technique works by generating localized heat from light exposure, which selectively kills cancer cells while sparing normal tissues.
Early studies suggest that this method could enhance other treatments, such as immunotherapy or targeted drugs, by weakening tumor cell membranes and stimulating an immune response.
Researchers are currently exploring its effectiveness for breast, colon, and other cancers, while developing implantable systems to provide continuous photothermal therapy internally.
One of the major advantages of this innovation is its minimal systemic toxicity, promising reduced pain and faster recovery compared with conventional treatments.
While still in the experimental stage, photothermal therapy could redefine cancer care, offering more precise, cost-effective, and humane treatment options.
The research represents a significant breakthrough in light-based medical technologies, highlighting the potential of non-invasive therapies in oncology.
