Scientists Find Breakthrough Use of Light to Kill Cancer Cells

In a world-first, scientists have developed a breakthrough treatment that uses light to kill cancer cells.

We often think of light as a life-giving source, but in the case of photoimmunotherapy — the use of light to help a person’s own immune system fight cancer — light can both be a source of life, for the patient, and death, to cancer cells.

A multidisciplinary team of European scientists joined forces to design the new treatment, which works by combining a special fluorescent dye with a cancer-targeting compound.

Shining light on the compound forces cancer cells to glow in the dark, helping surgeons to remove more of the tumors compared with existing techniques.

Then, the surgeon would shine near-infrared light on the site, switching the compound into tumor-killing mode and killing off any remaining cells.

      The trial of this therapy was done on mice with a particularly aggressive form of brain cancer called glioblastoma.

      Findings showed that the mice had clear signs of tumor death in as little as one hour after exposure to the light. The treatment also triggered an immune response that could mount a new attack on cancer should it come back.

      Study leader Dr. Gabriella Kramer-Marek told The Guardian, “Brain cancers like glioblastoma can be hard to treat, and sadly, there are too few treatment options for patients. Surgery is challenging due to the location of the tumors, and so new ways to see tumor cells to be removed during surgery and to treat residual cancer cells that remain afterward could be of great benefit.”

      Scientists are quite hopeful that the results will be duplicated when they study the treatment of humans. In the meantime, this trial has shined a light at the end of a long, dark tunnel.

      A Guide to Healing Adrenal Fatigue With Emoting And Herbs

      Your adrenals are small glands that sit on top of your kidneys, much like ice cream atop a sugar cone. At first glance, they might look like two old, hump-backed men, their backs to the camera, crouched over a table playing chess. Found within your endocrine system and comprised of two parts, the adrenal cortex, and inner adrenal medulla, these glands look similar to brains, which is probably the best metaphor. 

      Your adrenals fuel and run your body’s operations by producing then releasing hormones into your bloodstream, without which, you’d soon expire. Here are your body’s essential hormones that your adrenals produce:

       

      • Adrenaline: also known as epinephrine, is both a hormone and a medication. In partnership with noradrenaline, it helps you prepare your fight or flight responses. 

       

      • Aldosterone: a steroid hormone that helps you conserve sodium in your kidney, salivary glands, sweat glands, and colon. 

       

      Without these musketeers, you’d find it difficult to think, move, or breathe. This triune of energy and life are vital to remaining alive. When our adrenal glands are out of balance, they can fall into patterns considered to be adrenal gland disorders. Our bodies find it difficult to break out of these types of patterns.

      “Trying to describe a good marriage is like trying to describe your adrenal glands. You know they’re in there functioning, but you don’t really understand how they work.” — Helen Gurley Brown
