Red light therapy is widely used for skin rejuvenation, alivio del dolor, y curación de heridas. But a common concern is: Can red light therapy cause cancer cells to grow?
La respuesta corta: No, It Doesn’t Cause Cancer Growth
According to current research, red light therapy does not cause cancer and does not make existing cancer cells grow faster. De hecho, red light uses non-ionizing light, which means it doesn’t damage DNA like UV or X-rays do.
What the Science Says
- Non-ionizing wavelengths (like 630nm–850nm used in red light therapy) are safe and do not cause mutations in cells.
- Some early studies even show that red light may help reduce inflammation and improve the quality of life in cancer patients—such as easing side effects from chemotherapy.
Important Notes
- Red light therapy is not a cancer treatment.
It should never replace medical advice or oncology treatment. - Avoid using red light directly over tumors unless approved by a healthcare provider.
Pensamientos finales
Red light therapy is considered safe for most people and does not cause or worsen cancer. If you have a history of cancer or are currently under treatment, consult your doctor before use.
