If you are diagnosed with this cancer, your physician may recommend undergoing cancer colon laser treatment instead of a surgical procedure. Laser light is applied to cut cancerous tissue with high level of accuracy, as it involves a focused laser beam. There are three types of lasers applied to treat cancer cells: argon, carbon dioxide (CO2), and neodymium (yttrium aluminum garnet [Nd: YAG]).
While argon laser and CO2 laser can only incise the skin’s surface to eradicate tumors without penetrating into deeper layers, Nd:YAG laser is capable to exterminate cancers in internal organs like cancers in the large intestine, uterus, and esophagus.
Laser-induced interstitial thermotherapy (LITT)
This laser therapy is also known as interstitial laser photocoagulation to treat the cancer. An endoscope, a thin and flexible tube, is inserted through the anus. The cancer surgeon will insert an endoscope to scrutinize the large intestine. The endoscope is connected with an optical fiber and inserted into a tumor. Laser emits light through the endoscope and optical fiber, burns off the cancer cells, and eventually exterminates them. As the treatment applies heat, cancer cells find it difficult to live. The therapy uses Nd:YAG laser because it can pass through a curved optical fiber into the targeted tissue.
