Key takeaways
- There is little to no evidence pointing to red light therapy causing any form of cancer.
- Although red light therapy comes with a high penetrating power, it does not damage the DNA or increase cancer risk.
- Red light therapy can alleviate side effects of cancer treatment such as painful inflammation and ulceration of the mouth.
- Red light therapy is not a cure for cancer, however, its benefits can be supportive for cancer patients, especially in managing side effects of cancer treatments like surgery, radiation and chemotherapy.
There are numerous factors that can contribute to the development of cancer, including genetics, lifestyle choices, and environmental exposures. However, red light therapy is not among these causes and is considered a safe treatment option when used appropriately. In this article we would look at the possible relationship between red light therapy and cancer.
Does red light therapy cause cancer?
No, red light therapy does not cause cancer. Red light therapy uses low-level wavelengths of red and near-infrared light to penetrate the skin and promote healing, reduce inflammation, and alleviate pain. Unlike ultraviolet (UV) light, which is known to damage DNA and increase cancer risk, red light therapy operates at a different wavelength that does not have the same harmful effects on cellular structures.
Numerous studies have demonstrated the safety of red light therapy, and it is widely used in medical and cosmetic treatments without evidence linking it to cancer development. However, individuals with a history of skin cancer or those on photosensitizing medications should consult with a healthcare provider before starting red light therapy to ensure it is safe for their specific condition.
Benefits of red light therapy for cancer
While red light therapy (RLT) is not a treatment for cancer itself, it offers several supportive benefits for cancer patients:
- Pain Relief: RLT can help manage pain associated with cancer and its treatments, such as surgery or chemotherapy, by reducing inflammation and promoting healing.
- Reduced Inflammation: The therapy can decrease inflammation, which is often a significant source of discomfort for cancer patients.
- Wound Healing: Post-surgical wounds and radiation-induced skin damage can heal faster with RLT, enhancing recovery and comfort.
- Alleviating Side Effects: RLT can reduce side effects of cancer treatments, such as oral mucositis (painful inflammation and ulceration of the mouth), improving the quality of life.
- Improved Mood and Energy Levels: RLT can boost mood and energy levels, which can be beneficial for overall well-being during cancer treatment.
- Immune Support: Some studies suggest that RLT can help modulate immune responses, potentially supporting the body’s natural defenses.
Does red light therapy treat cancer?
Red light therapy (RLT) does not treat cancer. RLT is primarily used for its healing and anti-inflammatory properties, helping to alleviate pain, promote tissue repair, and reduce inflammation. These benefits can be supportive for cancer patients, especially in managing side effects of cancer treatments like surgery, radiation, and chemotherapy.
However, RLT is not a substitute for conventional cancer treatments such as surgery, chemotherapy, radiation therapy, and immunotherapy. There is no scientific evidence to suggest that red light therapy can cure or directly treat cancer. Patients should always follow their oncologist’s treatment plan and discuss any complementary therapies, including RLT, with their healthcare team to ensure safety and compatibility with their overall treatment strategy.
Side effects of red light therapy for cancer patients
While red light therapy (RLT) is generally considered safe, cancer patients should be aware of potential side effects and considerations:
- Skin Sensitivity: Some patients may experience mild redness, irritation, or sensitivity at the site of treatment, particularly if the therapy is used frequently or for prolonged periods.
- Increased Photosensitivity: Cancer patients undergoing certain treatments or taking specific medications may have increased photosensitivity, which could make them more susceptible to light-induced skin reactions.
- Temporary Discomfort: During or after a session, some individuals might feel warmth or tingling in the treated area, which usually subsides quickly.
- Interaction with Treatments: There is limited research on how RLT interacts with various cancer treatments. Patients should consult their healthcare provider to ensure that RLT does not interfere with their primary treatment plan.
- Overstimulation: In rare cases, RLT might lead to overstimulation of treated areas, causing temporary exacerbation of symptoms such as tingling or discomfort.
- Eye Safety: Direct exposure to the eyes should be avoided, as it can cause eye strain or damage. Protective eyewear is recommended during treatment.
Frequently asked questions
Is Red Light Therapy FDA Approved?
Yes, red light therapy devices are FDA-approved for various treatments. These devices typically target areas such as the face and body and use red, near-infrared, and sometimes blue LED light. Treatment sessions usually last about 30 minutes, depending on the specific device and condition being treated.
What are the Benefits of Red Light Therapy for the Brain?
Red and near-infrared light photons can penetrate the skull and reach brain cells, stimulating the mitochondria to produce more ATP (adenosine triphosphate). This increase in cellular energy can lead to clearer, sharper thinking and improved cognitive function.
Who Should Avoid Red Light Therapy?
Certain individuals should avoid red light therapy due to specific contraindications. These include people with retinal diseases, such as those related to diabetes, and individuals taking photosensitizing medications like lithium, melatonin, phenothiazine antipsychotics, and certain antibiotics.
