Treatment using laser is a medical treatment that uses light that is focused while on the other hand laser stands for light amplification by stimulated emission of radiation. The laser light is tuned to specific wavelengths that allows to be focused into powerful beams. Laser light intensity is too high that it can be used to shape diamonds or even cut steel. Laser therapy has various uses in the medical field. Some of the functions include; relieving symptoms of cancer, removing kidney stones, improving vision, treating hair loss due to aging, shrinking and destroying tumors and treating pain that include back and nerve pain.
In terms of relieving symptoms of cancer, laser treatment is useful in the early stages of some cancers such as basal cell skin cancer, vulvar cancer, cervical cancer, penile cancer, vaginal cancer and non-small cell lung cancer. In addition to the uses of laser therapy include a sealing effect on some areas that require sealing. The areas to be sealed include; lymph vessels, blood vessels and nerve endings. In order to help prevent blood loos then blood vessels are sealed. Lymph vessels are sealed in order to reduce swelling and limit the spread of tumor cells. The use of laser treatment to seal nerve endings is done to reduce pain after surgery.
Aside from the medical field, laser treatment has its uses in the cosmetic industry. The functions of laser treatment cosmetically include; removing hair, removing tattoos, lessen the appearance of wrinkles and remove warts, birthmarks, moles and sunspots.

Treatment using laser under general anaesthesia has resulted to some potential health risks. Potential health risk include pneumonia, heart attack, stroke and confusion after waking from operation. Accessibility of laser treatment is quite hard as they are very expensive. Carbon dioxide lasers, erbium, ablative and non-ablative, fractional lasers, alexandrite and IPL these are examples of cosmetic lasers.
Work stations like hospitals are equipped with key tools and equipment for laser therapy to be successful. It is necessary for laser treatment companies and hospitals to take their staff for seminars so as to keep them updated on how to use new advanced technology.
