Cancer treatment has seen many advances in recent years, and one therapy that’s gaining attention is red light therapy (also known as photobiomodulation). Red light therapy uses specific wavelengths of light to promote healing, reduce inflammation, and support cellular repair. While not a standalone cure for cancer, it has shown promise as a complementary therapy that can enhance the effectiveness of traditional treatments like chemotherapy and radiation. In this article, we’ll explore how red light therapy may benefit cancer patients, its potential effects, and what current research says about its role in oncology.
What Is Red Light Therapy?
Red light therapy involves exposing the skin to low levels of red or near-infrared light. This light penetrates deep into the tissues, stimulating cellular processes that aid in healing and reducing inflammation. Red light therapy has been widely studied for its use in treating skin conditions, reducing pain, and speeding up recovery from injuries.
In the context of cancer treatment, researchers are investigating how red light therapy might help improve patient outcomes by addressing some of the common side effects of conventional cancer therapies, such as pain, inflammation, and tissue damage.
How Does Red Light Therapy Work in Cancer Treatment?
At the cellular level, red light therapy works by interacting with mitochondria, which are the powerhouses of our cells. When cells absorb light from red light therapy, it boosts the mitochondria’s ability to produce energy, promoting better cellular function and repair. This process can be particularly beneficial for cancer patients undergoing treatments that damage healthy cells, such as chemotherapy and radiation.
Dr. Michael Hamblin, an expert in photomedicine at Harvard Medical School, explains that red light therapy can “stimulate cellular repair and reduce inflammation,” which is especially important in oncology, where patients often experience tissue damage and inflammatory side effects from their treatments.
Benefits of Red Light Therapy for Cancer Patients
1. Reducing Pain and Inflammation
One of the key benefits of red light therapy is its ability to reduce pain and inflammation, which are common issues for cancer patients. Treatments like surgery, chemotherapy, and radiation often leave patients with lingering pain in affected areas. Red light therapy can help by reducing inflammation at the cellular level, which in turn can reduce pain and discomfort.
Dr. Scott Nelson, an oncologist, points out that while “red light therapy is not a standalone cure for cancer, it can be a valuable adjunctive treatment” for reducing pain and improving patient comfort (American Cancer Society). Patients undergoing cancer treatments often report feeling fatigued and experiencing chronic pain, and red light therapy may offer relief by soothing inflamed tissues.
2. Enhancing the Healing Process
Cancer treatments can damage healthy tissues, particularly around the treatment sites, leaving patients with sores, burns, or other wounds. Red light therapy has been shown to promote faster healing of these damaged tissues by encouraging the production of collagen and improving circulation to the area.
For example, cancer patients undergoing radiation therapy frequently experience a painful side effect called radiation dermatitis, which leads to redness, swelling, and peeling skin. Red light therapy has been used to soothe and heal the skin more quickly, helping patients recover faster from these side effects.
A review published in the Photomedicine and Laser Surgery Journal highlighted the benefits of photobiomodulation in oncology, noting that red light therapy can “promote tissue repair and alleviate side effects like mucositis and dermatitis.” These conditions are painful and affect a patient’s quality of life, but red light therapy can provide much-needed relief during their treatment.
3. Supporting Immune Function
Red light therapy may also support the immune system, which cancer treatments often weaken. Some research suggests that red light therapy can help modulate the immune response, boosting the body’s natural defenses against infections and improving overall resilience.
Dr. Praveen Arany of the University at Buffalo explains that photobiomodulation, including red light therapy, has been found to “improve the quality of life for cancer patients by alleviating side effects of chemotherapy and radiation, such as mucositis and dermatitis.”
While researchers are still exploring the connection between red light therapy and immune function, this therapy’s potential to enhance the body’s ability to recover from cancer treatments makes it a promising complementary option.
4. Enhancing Traditional Cancer Treatments
Another exciting aspect of red light therapy is its potential to work alongside traditional cancer treatments like chemotherapy and radiation therapy. Some studies suggest that red light therapy may enhance the effectiveness of these treatments by making cancer cells more sensitive to them.
A report from the International Journal of Cancer Research and Treatment examined various clinical trials and found that low-level laser therapy (LLLT), including red light therapy, could “enhance the efficacy of chemotherapy and radiation therapy, reduce tumor growth, and improve patient quality of life.”
By increasing the effectiveness of standard treatments, red light therapy may help improve outcomes for patients while reducing the amount of time they need to spend undergoing harsh therapies.
Limitations of Red Light Therapy in Cancer Treatment
While red light therapy offers promising benefits, there are also concerns about its safety, particularly whether it might cause cancer. Current research suggests that red light therapy does not cause cancer and is generally safe when used appropriately.

Additionally, more research is needed to fully understand how red light therapy can best be used in oncology. While early studies are promising, larger clinical trials are necessary to confirm its effectiveness in treating cancer or enhancing other therapies.
Patients considering red light therapy should always consult their doctors before starting, as the therapy may not be appropriate for all cancer types or treatment stages. Medical professionals can guide patients on how to integrate red light therapy safely into their treatment plans.
What Does the Research Say?
Recent studies have shown that red light therapy can be beneficial for cancer patients in several ways. For instance, the Photomedicine and Laser Surgery Journal review of photobiomodulation in oncology noted that red light therapy helps reduce inflammation, promotes healing, and alleviates common side effects of cancer treatments.
Similarly, the International Journal of Cancer Research and Treatment reported that low-level laser therapy could reduce tumor growth and enhance the effectiveness of traditional treatments, such as chemotherapy and radiation. These findings suggest that red light therapy holds great potential as an adjunctive therapy for cancer patients, though more research is needed to determine the optimal treatment protocols.
Conclusion: Red Light Therapy as a Complementary Cancer Treatment
Red light therapy has shown promising benefits for cancer patients, particularly in reducing pain and inflammation, promoting tissue repair, and potentially enhancing the effectiveness of chemotherapy and radiation. While it is not a cure for cancer, it can serve as a helpful complementary treatment, making the overall cancer treatment process more comfortable and improving the quality of life for patients.
As researchers conduct more studies, red light therapy may become an increasingly common tool in the fight against cancer. If you’re undergoing cancer treatment and are interested in exploring red light therapy, consult with your healthcare provider to ensure it’s a safe and suitable option for you.
