Researchers from The University of Texas at Austin and the University of Porto in Portugal have unveiled a promising cancer treatment that utilizes LED light in conjunction with tiny flakes of tin. This innovative approach aims to effectively eliminate cancer cells while preserving healthy tissue.
As part of their study, the team exposed skin cancer cells and colorectal cancer cells to SnOx nanoflakes, which are flakes of tin oxide. The cells were placed in separate test tubes and subjected to infrared LED light. Remarkably, after just 30 minutes of exposure, the treatment resulted in the destruction of up to 92% of skin cancer cells and 50% of colorectal cancer cells, leaving healthy cells unaffected.
The researchers aim to further investigate the interaction between light and heat in this treatment and plan to develop devices to facilitate its application in clinical settings. This research is part of the UT Austin Portugal Program, a collaborative initiative focused on advancing science and technology.
Skin cancer, which is the most prevalent form of cancer globally, begins with the abnormal growth of skin cells, often in areas exposed to sunlight. It can invade and damage surrounding healthy tissue and has the potential to spread throughout the body. Among the various types of skin cancer, basal cell carcinoma and squamous cell carcinoma are among the most common, and they are often treatable. However, melanoma poses a greater risk due to its likelihood of metastasizing, complicating treatment options.
To reduce the risk of skin cancer, experts recommend protective measures such as wearing appropriate clothing and applying sunscreen when outdoors.
Colon cancer primarily affects older adults but can occur at any age. It originates in the large intestine or colon, typically starting as small, noncancerous growths known as polyps. Over time, certain polyps may turn cancerous. Regular screening procedures, including colonoscopies, are advised to detect and remove polyps, thereby preventing the onset of colon cancer.
