Does laser cause cancer? Is laser treatment safe?
First things first, what is laser? Laser is tech acronym for Light Amplification by Stimulated Emission of Radiation. It is fundamentally different from other light sources and is utilised in various purposes such as barcode scanning, genetic studies, cosmetic surgery, etc. Nowadays, it has more uses in hair transplant surgeries, body laser treatment and facelifts to improve the look of patients disfigured during accidents, injuries or serious burns.

Does this treatment cause cancer?
This is one question that lingers in the minds of many people. There is no definite answer to this question since the long-term consequences of laser therapy have not yet been studied. Experiments conducted in human skin anomalies have shown some changes after laser hair removal. Therefore, scientists suggest that caution should be observed while undertaking cosmetic laser therapy for those with a personal/family history of skin cancer until more comprehensive research concludes that such changes cannot cause cancer.

How does it work?
Laser therapy makes use of mild radiation in the form of a highly concentrated light source which produces a tiny laser beam. In case of hair removal, the beam kills the hair follicles halting further growth of hair from such follicles. The technology does not use the harmful wavelengths found in sunlight. Some of the stronger sunlight radiations have been proven to damage DNA within cells and even cause cancer.
What are its major uses?
The mild radiation in laser surgery is different from the strong radiation, e.g. (x-rays and nuclear radiation) which are also known carcinogens, i.e. cancer-causing substances. Some of the key benefits are as follows:
- Removal of unwanted hair removal
- Other cosmetic treatments such as removal of tattoos
- Some dental procedures like the treatment of root canal infections.
- Prostate, eye and skin surgery
- Kidney stones, i.e. the concentration of some salts in the kidney that block the flow of fluids, can also be eradicated through this technology.
- Most cancer treatments including skin cancer use laser therapy to kill the cancerous tumours.
How safe is laser treatment?
The following are factors that enhance the safety of laser treatment to the patient.
- There is less bleeding during the procedure
- There is less pain since the CO2 laser beam seals nerve fibres
- There is less risk of infection since the procedure kills bacteria
- Quick recovery time due to less bleeding, swelling and pain
India as a center for laser surgery
India is quickly becoming a popular destination for laser hair therapy. Indian residents are nowadays going for cosmetic procedures more than ever especially the youth and young professionals. This trend has primarily been driven by western culture as well as modern life patterns.
Likewise, many people from all over the world travel to India for laser hair therapy. For this reason, there is a high demand for laser hair removal specialists in India. It is also common knowledge that appearance immensely affects an individual’s body image and how others feel about the person.
In conclusion, laser treatment has shown some great promise for improving various skin and cosmetic hair surgeries. However, caution still needs to be observed to avert the potentially dangerous effects it can cause.
