One of the latest treatments is laser therapy :
One of the latest treatments in the field of medicine is laser therapy. LASER is actually a short form for "light amplification by stimulated emission of radiation". In understandable terms it means simply that light radiation is focussed so precisely that it becomes powerful enough to even cut stone.
How can this power be useful in the medical field?
How can this power be useful in the medical field? In experienced hands laser becomes a most efficient tool which can cut through body tissues with such exactitude that any damage to the surrounding tissues is completely avoided. Thus there is less pain, less swelling, less blood loss and lesser scarring. This translates into easier, quicker and better healing for the patient.
Uses of laser in treatment are manifold :
The uses of laser in treatment are manifold. Lasers are used for surgeries to zap away precancerous growths, tumours, polyps, warts on the skin. They are used to cut away unreachable portions of tissues as in the brain, prostrate or other organs. With lasers, blood vessels and lymph vessels can be sealed to prevent blood loss and stop the spread of cancers.
In the hands of a trained and skilled surgeon lasers can be used to perform almost any surgical procedure. Surgeons use them to cut, coagulate, ablate, and remove tissue. They can perform complex surgeries all the while reducing blood loss, post operative pain, chances of infections, spread of cancer and better wound healing.
Laser surgery is often standard for surgeries or procedures of the heart, teeth, skin, eyes, ears, nose, throat, stomach, intestines, on the brain and nervous system, in women's diseases, on the urinary system and in treatment of cancers.
Lasers can be used to correct refractive errors in the eyes, for cataract surgery and to repair a detached retina. Laser therapy can also be used to treat chronic pain as in sciatica or in cancers. Laser treatment of the skin includes permanent hair removal, removal of acne scars, birthmarks, tattoos, sunspots, wrinkles and other blemishes.
Lasers are also used to treat many cancers including those of the cervix, vagina, vulva, penis, certain cancers of the skin and lungs. Some other conditions in which laser therapy can be used are ablation of tumours, angina, cold and canker sores, gum disease, tooth decay, ectopic pregnancy, endometriosis, fibroid tumors, kidney stones, gallstones, astigmatism, migraines, benign enlargement of prostate, nosebleeds, ovarian cysts, ulcers and varicose veins.
What are the different types of lasers treatments?
There are several different types of lasers, using solid, liquid or gas. The three types of lasers most often used in medical treatment are the carbon dioxide or CO 2 laser used mainly for surgeries, the Nd: YAG laser used to penetrate deeper into tissues and the Argon laser used for eye surgery and superficial skin disorders. With light-sensitive dyes the Argon laser can also shrink or dissolve tumors, called photodynamic therapy or PDT.
In modern medicine, lasers with better precision and safety, are being increasingly deployed for a vast array of pathologies. From life-threatening diseases to distressing cosmetic defects, laser therapy has led to great advancements in treatment of diseases benefitting both patients and doctors.
