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.
Research Shows Effectiveness of Breathwork in Healing
Breath, most of us take it for granted, and yet as an influx of recent studies show, when we learn to control it, it can be the key not only to our physical wellbeing but to our spiritual transformation.
Breathwork is the conscious awareness and control of the breath through the practice of various techniques. While breath practices have been incorporated for millennia in many religious and spiritual traditions, they were largely forgotten with the rise of the modern western world. Today, however, we are in the midst of a massive resurgence in interest in these ancient practices.
Ben Stewart is a filmmaker who has been researching and practicing breathwork for years. “We always have breath, it’s free, and it’s relegated to the subconscious for the most part of our lives,” he said.
When we bring it back into the conscious realm, just the very act of bringing awareness to the breath is something that augments the experience of what the breath is doing to us, but also just becoming aware of your breath allows you to realize how much we actually hold our breath, how interrupted and inconsistent our breathing really is.”
