There are a steadily increasing list of applications of the use of low level laser light in medicine. Now a group of researchers have devised a brilliant cancer fighting technique using nanoparticles and treatment with near infra-red laser light to provide a 5 day window during which cancer cells’ defense mechanism against chemotherapy is paralyzed.
"This.... overcomes the drug resistance of multidrug-resistance NCI/RES-ADR cancer cells and their CSC's both in vitro and in vivo. Ultimately, the drug-laden LSC nanoparticles exhibit superior safety and efficacy for therapy of multidrug-resistant tumors."
The study published here is an incredibly sophisticated application of available technologies. The use of laser light is burgeoning. For example, we use it extensively in our clinic; and recently described our presentation of a study we carried out showing enhancement efficacy of PRP (platelet rich plasma) when combined with the use of laser probes inside the treated joint. However, the use of lasers in cancer has come to be its own field, and the above described description of laser light to block cancer cell drug resistance is perhaps the most exciting breakthrough in this area yet described.
