New Cancer Treatment Uses Laser To Destroy Cancer Cells

scientists are using light to kill cancer cells.
the new technique involves delivering cancer -killing genes into the cancer cells.
the genes are delivered into the cancer cells inside tiny capsules nanorods.
once they enter the cell, the nanorods are heated up from the out side with the help of the near-infrared laser.
this heat activates the genes that will eventually kill targeted cancer cells.
the new method was tested on cell models and it selectively destroyed cancer cells without harming normal cells.
the system could eventually be used for molecular cancer therapies .

What is laser light?the word laser stands for light amplification by stimulated emission of radiation.
What is laser therapy, and how is it used in cancer treatment?Laser therapy uses high-intensity light to treat cancer and other illnesses.
What types of lasers are used in cancer treatment?3 kinds of laser we can use in the treatment of cancer (CO2) lasers, argon laser, and neodymium:yttrium-aluminum-garnet (Nd:YAG) lasers.
carbon dioxide laser:

What are the advantages of laser therapy?so they do less damage to normal tissues and less pain , less bleeding, operations are usually shorter.
What are the disadvantages of laser therapy? Surgeons have to know how is working before they can do laser therapy, and strict safety precautions must be followed. is expensive and requires bulky equipment.
