Red Light therapy for cancer treatment

Is Red Light Therapy for Cancer? Well, if you’ve seen some of our other articles for Red Light (aka Photobiomodulation, PBM) then you know it is tested and proven to treat so many things! Including: Alzheimer’s, Parkinson’s, Traumatic Brain Injuries, Diabetes, PTSD, Depression, Hashimoto’s – I could go on all day. PBM is so versatile that is used as a treatment for so many health conditions. But is it safe for those with cancer?

What is Photobiomodulation?

RLT is a medical treatment that uses low-level light therapy to stimulate healing and reduce inflammation. It is a safe and non-invasive therapy that has been shown to have many health benefits.

Benefits of Red Light Therapy can include:

Red Light therapy for Cancer

While PBM does not directly kill cancer cells, but it has been shown to have a positive effect on the immune system. This effect is responsible for identifying and destroying cancer cells. In addition, RLT has also been shown to reduce inflammation and promote healing. These effects can help reduce the side effects of cancer treatments like chemotherapy and radiation therapy.

Studies have shown that PBM can improve the function of immune cells, including natural killer cells and T cells, which are important in fighting cancer. RLT has also been shown to reduce inflammation and promote healing, which can help reduce the side effects of cancer treatments like chemotherapy and radiation therapy. Moreover, there are two clinical trials showing increased survival in cancer patients who received PBM therapy!

There have been several studies investigating the effects of PBM on cancer cells in vitro (in a laboratory setting) and in vivo (in animal models). Some of these studies suggest that PBM can have anti-cancer effects by inhibiting tumor growth and inducing cancer cell death. However, the results of these studies are mixed. Some studies suggest that PBM may have anti-cancer effects, while others show no significant effects. Therefore, more research is needed to fully understand the potential of PBM as a cancer therapy.

Red Light Therapy for Cancer | Breast Cancer

One study published in 2018 investigated the effects of PBM on breast cancer cells in vitro. The study found that PBM inhibited the growth of breast cancer cells and induced cancer cell death, suggesting that PBM may have potential as a therapy for breast cancer.

Red Light Therapy for Cancer | Ovarian cancer

Another study published in 2019 investigated the effects of PBM on ovarian cancer cells in vitro. The study found that PBM inhibited the growth of ovarian cancer cells and induced apoptosis, suggesting that PBM may have potential as a therapy for ovarian cancer.

Can Red Light Therapy Shrink Tumors

This study investigated the potential of using red light (RL) phototherapy as a treatment for melanoma, a type of skin cancer. Despite advancements in cancer treatment, melanoma rates are increasing, and some patients do not respond well to current therapies. The researchers aimed to see if RL could effectively inhibit melanoma growth and enhance anti-tumor immune activity.

In their experiments, they exposed melanoma cells to RL and found that it reduced cell growth and increased cell death without causing inflammation. RL also increased the production of reactive oxygen species (ROS) and activated a protein called p53, which plays a role in controlling cell growth. In mouse models with melanoma, RL treatment significantly slowed tumor growth and increased the presence of immune cells associated with fighting cancer.

Overall, the study suggests that RL phototherapy could be a promising addition to melanoma treatment. Further research is needed to determine the best ways to use RL in clinical settings.

Red Light Therapy for Cancer | Side effects of Cancer Treatment

There have also been several studies investigating the effects of PBM on cancer-related side effects, such as oral mucositis (inflammation of the mouth) and peripheral neuropathy (nerve damage in the limbs) in cancer patients undergoing chemotherapy. Some of these studies suggest that PBM can help reduce the severity of these side effects.

Overall, PBM therapy may have benefits in cancer patients. Given it’s ease of use, cost effectiveness and many benefits RLT makes a lot of sense for helping cancer patients.

Frequently Asked Questions:

Can near-infrared light cause skin cancer?

Red and near-infrared light have been proven to be safe – even when malignant tumors are present.

Is too much Red Light Therapy harmful?

When used properly, Red Light Therapy is not harmful and is safe for virtually everyone to use.

Can Red Light Therapy shrink tumors?

Red Light does not directly kill cancer cells, but it has been shown to have a positive effect on the immune system. This effect is responsible for identifying and destroying cancer cells.

Is Infrared Light good for Cancer?

PBM therapy (which uses Red and Infrared Light) may have benefits in cancer patients. Given it’s ease of use, cost effectiveness and many benefits RLT makes a lot of sense for helping cancer patients.

Can Red Light Therapy cause cancer to grow?

No, there have been no such cases in which PBM therapy was shown to cause accelerated cancer growth or adverse effects.

I started using red light therapy shortly after giving birth to my second child. I was desperate to head off any post partum depression this time around since I struggled with it with my first. It has helped even out my hormones so much! I've used it for a month so far, going on two and truly I feel amazing. I haven't been as tired even though my sleep is terrible and I feel in control of my crashing pregnancy hormones. This has truly been a God send for me!!
