In the world of alternative therapies, red light therapy is getting noticed for its possible advantages in helping cells grow and heal. But many people worry if it could cause skin cancer.

In this article, we look at the research and evidence to see if red light therapy is safe.

We’ll also discuss how it might be used in treating and preventing cancer.

Can Red Light Therapy Cause Skin Cancer?

People have been debating the pros and cons of red light therapy, and one big concern is whether it can lead to skin cancer. The good news is that it does not.

Red light therapy is thought to promote cell growth, which raised worries that it might encourage the growth of cancerous skin cells, especially in cancer patients. But in 2012, a study called “A Preliminary Study of the Safety of Red Light Phototherapy of Tissues Harboring Cancer” looked into this issue and found that it’s not a problem.

In this study, researchers tested red light therapy on mice with skin cancer. They treated one group with red light twice a day and left another group untreated. After 37 days, the tumors in the treated mice did not grow. This suggests that red light therapy, while helpful for healing wounds and generating new cells, doesn’t make cancer cells grow.

In fact, red light therapy might even be useful in treating skin cancer. A UK trial with over 100 patients showed that applying a special cream to cancerous skin and exposing it to red light for just 10 minutes was as effective as surgery, but less invasive. Using light to activate anti-cancer medications isn’t a new idea, and it could be a valuable tool for cancer treatment.

In general, red light therapy is commonly used to treat various skin problems. It’s believed to boost collagen production, reduce inflammation, and help with scar healing. The short wavelengths of red light activate skin cell mitochondria, reducing stress and improving circulation, which rejuvenates the skin and eases inflammation. While more research is needed on its cosmetic benefits, it’s clear that red light therapy is a safe procedure that doesn’t cause skin cancer. So, you can use it without worrying about that.

Additional Clinical Research Confirming the Safety of Red Light Therapy in Relation to Skin Cancer

It’s important to base our scientific conclusions on more than just one study. Fortunately, there is a lot of research that proves that red light therapy is safe and does not cause skin cancer.

A study from Russia looked at the effects of different laser doses on the immune systems of animals with cancer, and then they did similar research with 60 human cancer patients. The results showed that low-level laser therapy boosted the patients’ immune responses, helping them fight cancer without making the tumors grow. This research suggested that red light therapy, like RLT, could be beneficial for cancer patients.

Contrary to what some may think, red light does not cause or promote cancer, unlike the ultraviolet light used in tanning beds. The key difference is that ultraviolet light is a type of radiation that can damage DNA and lead to cancer, while red light is a different type of radiation with a wider wavelength that cannot harm DNA or cause cancer.

Other studies have indirectly confirmed the safety of red light therapy on human cells. For example, Brazilian scientists conducted a study on how low-intensity laser therapy affected bacterial growth in infected wounds. Bacteria can slow down the healing process, so it’s important to find ways to combat them without harming human tissue.

The study found that low-level laser therapy had minimal impact on bacterial growth, but it did stimulate collagen production in wounded tissues, which helps with healing. This shows that red light therapy is safe because it doesn’t harm human cells and may even have benefits by promoting tissue repair and wound healing.

Is Red Light Therapy Safe?

Red light therapy has been studied extensively, and the results suggest it’s unlikely to cause or speed up cancer growth. Instead, it seems to support healthy cell growth and function. But, is it entirely safe, and are there any potential downsides to this promising treatment? Red light therapy involves lasers that go into your body, and cells absorb these light particles. So, what does this mean for our cells in the long run?

As of now, scientists haven’t found any major problems linked to red light therapy. Reports of serious side effects are rare, and most people who undergo this therapy don’t experience pain or irritation. Like any medical procedure, red light therapy is generally safe if you take the right precautions. There have been some minor issues noted in a few cases, such as:

  1. Irritability
  2. Headaches
  3. Eyestrain

These problems usually affect individuals who are sensitive to light or get too much exposure. Even though red light lasers are quite safe, it’s important to protect your eyes with special goggles during sessions.

There have been accidents where people misused red light therapy devices and ended up with burns or blisters. These accidents usually happen when people fall asleep using a device or accidentally touch broken wires.

To sum it up, red light therapy is typically safe, but like any medical treatment, it should be done correctly and carefully. If you’re thinking about red light therapy, here are some precautions:

  1. Talk to a doctor before starting therapy.
  2. Get treatment from a trained professional for best results.
  3. Check customer reviews or get referrals if you plan to use red light therapy at a spa or salon.
  4. If using a home device, follow the instructions carefully.
  5. Find out the right light wavelength for your specific condition.
  6. Always wear eye protection during treatment.
  7. Don’t use a broken or faulty device.
  8. Avoid falling asleep during red light therapy sessions.

When you take these precautions, red light therapy is a safe option for various health and cosmetic concerns. Researchers are still studying its effectiveness for different conditions, but it’s generally not known to worsen existing problems. In fact, for issues like hair loss, red light therapy is becoming a safe and painless alternative to treatments with potential side effects, providing hope for those seeking effective solutions for their physical concerns.

Can Red Light Therapy Help Treat Cancer?

To answer this question, let’s recap the main points discussed earlier. First, can Red Light Therapy (RLT) help fight cancer cells? Research, including studies by Dr. Hisataka Kobayashi at the National Cancer Institute (NCI), suggests that it might have a positive impact.

In their research, scientists tested monoclonal antibody (mAb) therapy on mice. They found that these antibodies could attach to cancer cells, and when exposed to infrared light, these cancer cells began to die quickly. This approach has shown success in various tests on animals with different types and sizes of tumors.

It’s important to mention that the specific wavelengths of red or light therapy that work for most cancers appear to be in the low-800s nm and mid-600s nm ranges. At these wavelengths, the light can effectively penetrate the skin and soft tissue of the organs.

Moreover, for the treatment to be effective, the device’s light intensity should be at least 100 milliwatts per square centimeter (mw/cm²) to ensure it reaches the necessary depth.

Using Red Light Therapy to Treat Different Types of Cancer

Red light therapy (RLT) is gaining recognition as a potential treatment for cancer. It’s important for the medical community to explore its use for various cancer types. Here’s a quick look at how RLT may work for four common types of cancer:

  1. Breast Cancer: RLT shows promise for treating breast cancer, as it primarily affects surface-level soft tissue, making RLT effective in this case.

  2. Brain Cancer: Treating brain cancer with RLT is challenging due to limited infrared light penetration through the skull. Higher wavelength frequencies could be used, but this may carry some risks, which may be justifiable given the severity of brain cancer.

  3. Skin Cancer: RLT is highly effective for treating skin cancer because it can easily penetrate the skin.

  4. Lung Cancer: Similar to breast cancer, RLT has shown positive results in treating lung cancer, as both involve soft tissue areas that can be targeted effectively with this therapy.
