Yes but….not just any light, but UV light. Specifically UVC (100-280nm) and more specifically 254nm. This wavelength can be generated using a wavelength specific laser or LED lights. Then there’s the question how to get the light to the cancer cells, as UV light will kill healthy cells as easily as it would kill cancer cells. Researcher use a trick call photoactivator chemicals that are tuned to absorb UV light at the 254nm wavelength. So the idea is to drink a solution containing the photoactivator or through IV to get it into your system. The activator is absorbed by the cells, faster in cancer cells, and hangs around a while. If we had a skin cancer, we could direct the UV light to that area of the skin to kill the cancer. If the cancer was in our throat to our stomach, a UV light endoscopy could be used to direct the light to kill the cancer. But for MM, you would need to remove the blood from the patient, pass it through a UV source and then move it back into the patient to kill the cancer in the blood. Unfortunately, there would be no way to get the UV light into the bone marrow, where these abnormal MM cells are being generated.

I read about this using ultraviolet light, your blood goes through a machine that subjects it to the ultraviolet light and then the blood goes back into your body. Sounds absolutely amazing and promising, and I would love to see more institutions researching it.

While regular light itself cannot kill cancer cells, certain types of radiation (which includes some forms of light energy) can affect cells. Ionizing radiation, which is high-energy waves or particles, can interact with DNA and cause changes in cells.

While regular light itself cannot kill cancer cells, certain types of radiation (which includes some forms of light energy) can affect cells. Ionizing radiation, which is high-energy waves or particles, can interact with DNA and cause changes in cells.

In myeloma treatment, radiation therapy may be used in a targeted way to treat specific areas affected by the disease. This is different from natural light exposure. It's important to note that any treatment involving radiation should only be done under proper medical supervision. If you're curious about radiation therapy as a treatment option for your myeloma, this is something to discuss with your healthcare team who can evaluate if it would be appropriate for your specific situation.
