Can red light therapy cause cancer?

Red light therapy (RLT) has become a beacon in the health and wellness industry, revered for its non-invasive approach and multitude of benefits. However, its interaction with cancer cells and tumors has been a topic of much discussion and research. With the rise in its popularity, it’s crucial to dissect the claims and concerns surrounding RLT and cancer.

Can Red Light Therapy Cause Cancer Cells to Grow?

Current research suggests that while RLT can invigorate the mitochondria within cells, potentially aiding in cell repair and growth, there is no concrete evidence that it causes cancer cells to proliferate. On the contrary, certain studies indicate that RLT may have a role in inhibiting the growth of cancer cells. In light of these findings, the concern that RLT could accelerate cancer cell growth seems unfounded at present.

Does It Cause Skin Cancer?

As for the relationship between RLT and skin cancer, the outlook is rather positive. Given its non-ionizing nature and low-level light use, RLT has not been linked to causing skin cancer. In fact, RLT has been successfully utilized in the treatment of certain skin conditions, potentially offering benefits due to its healing properties.

Is Red Light Therapy Safe for Cancer Patients?

The safety of RLT for cancer patients remains a complex issue. While there’s a potential that RLT could spur the growth of tumors at higher wavelengths, further research is needed to fully understand the risks and benefits. That said, RLT has been used to mitigate side effects associated with cancer, such as inflammation and pain, enhancing the quality of life for some patients.

Can Red Light Therapy Shrink Tumors?

Innovative approaches like monoclonal antibody (mAb) therapy in combination with infrared light have shown promise in animal studies, where cancer cells began to die upon treatment, hinting at the potential for RLT to affect tumor growth. However, these findings are preliminary, and more research is necessary, particularly in human clinical trials.

Can Red Light Therapy Be Harmful?

As with any therapeutic intervention, the risk of harm with RLT is a valid concern. Current knowledge indicates that RLT, when used according to guidelines, poses minimal risk. The therapy is generally considered safe with no significant side effects reported in most studies.

Is Red Light Therapy a Gimmick?

Considering the breadth of scientific studies and clinical applications, RLT is far from a gimmick. Its use is supported by a substantial body of research that underscores its therapeutic benefits across a range of conditions, from skin health to muscle recovery.


The intricate relationship between RLT and cancer is still being unraveled by the medical and scientific community. While the potential of RLT in treating or impacting cancer is promising, it’s important to approach this therapy with informed caution, engaging with healthcare providers to understand its role in cancer treatment fully. As science advances, we may discover even more about the capabilities of RLT in oncology and beyond.

For those considering RLT, whether for general wellness or specific health concerns, it’s essential to consult with medical professionals and choose FDA-approved devices from reputable manufacturers to ensure the highest standards of safety and efficacy.

I’ve been using NeurocarePro for years, and their quality is always consistent. They have helped my practice with support. I highly recommend using NeurocarePro products and accessing their team of professionals for assistance with implementation and protocol needs.”

Dr. Richard Busch, DC, Clinic Owner

“UNBELIEVABLE Results!!! I purchased the 2-port controller with the lumbar pad from my doctor in hopes for improving the appearance of a 30yr old keloid scar on my stomach (it was raised & discolored) I am over the moon thrilled with the results. It has not only smoothed out to my skin surface but has completely returned to my original skin tone. I have actually had surgery to revise this incision with zero results, so as you can imagine Neurocare Pro therapy has provided me with a small miracle. Cannot thank you enough.“
