A brief review on Laser Treatment in Oncology

Laser therapy uses an intense, narrow beam of light to remove or destroy cancer and abnormal cells that can
turn into cancer. Tumor cells absorb light of different wavelengths (or colors) than normal cells do. So,
tumor cells can be targeted by selecting the proper wavelength of the laser. Laser therapy is a type of local
treatment, which means it treats a specific part of your body.
More extensive comparative studies of up-to-date surgical procedures, regarding the duration of surgery
when a laser is used versus a scalpel, are missing so far. Using an electrotome can provide sufficient
hemostasis during the tissue cut as well, but electrocontractility of the underlying muscle tissue cause a
reduced accuracy of the surgical cut compared to laser resections
