Fiber laser technology in medicine
Fiber laser technology has become one of the most powerful instruments in medicine, including cancer treatment. Laser therapy uses an intensely focused laser beam to destroy or shrink cancer cells. It can remove tumors while preserving healthy tissue. The therapy targets a specific part of the body to prevent further disease progression.
Tumor cells absorb light at different wavelengths compared to healthy cells. Selecting the appropriate fiber laser wavelength allows effective destruction of tumor cells.
Application of fiber laser therapy
Fiber laser treatment is mainly used in surgery, especially in complex operations with high patient risk.
Surgical applications
Fiber laser systems reduce pain, swelling, and bleeding. They allow specialists to seal lymphatic vessels, nerve endings, and blood vessels, minimizing complications during and after surgery.
Use across cancer stages
Fiber lasers can be applied at various cancer stages. They help limit the spread of cancer cells, treat precancerous cells on organ surfaces, and alleviate symptoms of advanced cancer. Fiber laser modules can destroy portions of tumors.
Endoscopic fiber catheter method
Fiber laser therapy is now often delivered via a flexible endoscopic fiber catheter. This narrow tube monitors internal tissues and delivers light directly to the therapy site. Specialists can destroy or cut tumors with precise laser beams.
Advantages and disadvantages
Compared to conventional surgery, fiber lasers have several advantages. They more accurately seal cut tissues, causing less damage. Patients experience reduced pain and scarring. Operations take less time, recovery is faster, and some procedures can be performed in a doctor’s office rather than a hospital.
Despite these benefits, fiber laser therapy has some drawbacks. It is more expensive than conventional tools, though specialized equipment is often cost-effective due to convenience. Laser therapy requires trained personnel, which can be a challenge for hospitals. The effects may not always be long-lasting, sometimes requiring repeat procedures. Overall, fiber laser systems provide more benefits than drawbacks, improving safety and convenience for patients and doctors.
