This technology is a type of treatment that kills cancerous tumors. This treatment is called

Photodynamic Therapy (PDT). It will improve this field because since the tumors are what causes the cancer/ is the cancer it could have the cancer removed or temporarily removed. This is better then what has been used previously because it makes the tumors weak and they then shine the light on the weak cells causing them to be destroying them in the process.Yes I do think this treatment is safe because it gets rid of the cancer cells, and it leaves the other cells alone in the process. This treatment is being used of cancer patients already.
