Laser treatment in the medical cancer field

In recent years, the development of laser therapy medicine is more and more rapid. The application in cancer treatment is also more and more widespread. For example, lasers can remove tumors. High power laser focused direct irradiation of tumors. Cancer tissue becomes vapor and fog. To eliminate cancer. In the future, laser therapy will be more widely used and breakthroughs in the field of cancer.

One of the photosynthetic therapies is to use a drug to make cancer cells very sensitive to light. When the laser is directly exposed to the lesion, the drug will react positively to destroy the cancer cells. The laser therapy is mainly used for the treatment of skin and brain cancer. Doctors say photodynamic therapy, unlike chemotherapy, has the advantage that it does not produce side effects; on the other hand, patients cannot use radiation many times, and lasers can be used more than once.

In the past five or six years, the technology used to treat cancer has been greatly improved, so many different hospitals can use it now, but it is not suitable for the symptomatic treatment of various forms of cancer. At present, the clinical application of laser in tumors is mainly limited to surface tumors (such as skin cancer, penile cancer, etc.) and intraluminal tumors (such as esophageal cancer, rectal cancer, etc.), and the treatment of visceral tumors is still in the exploratory stage.

Looking ahead, Professor Harry Mosley, Director of Bioimaging at Dundee University, UK, said that diagnosis was an exciting area in the field of lasers. Early diagnosis is that we illuminate the body somewhere to observe its response, distinguish subtle changes to feedback whether the patient has cancer, and improve the diagnosis through analysis.

Professor Nick Stone, of the Bioimaging Research Group at Royal Gloucestershire Hospital, confirmed the importance of laser diagnosis. "It will have a very different effect than before, providing a lot of information about abnormal cells in the body," he said. We can use lasers for rapid diagnosis, which will save a lot of money for the British national health insurance system. In order to alleviate the patient's pain, physical tissue examination is no longer needed to determine whether there are signs of lesions. “

At the same time, scientists have gained new perspectives through laser angiography to understand how diseases form and how cells prevent them. Scientists say that knowledge gained through this technology in the future will help doctors customize medicines according to their individual needs. This personalized drug can ensure effective defense against individual cancer with minimal side effects.

Rutherford Appleton Labs has been devoted to the in-depth study of laser equipment. "Laser is a huge sensor," said Dr. Catherine Lancaster of the center. She is now investing in a new development - laser research Scorpion. Medical experts use special tweezers consisting of two lasers to control and move microscopic particles to isolate individual cells. "Lasers can also provide a cheap way to accelerate particles," Dr. Lancaster said. It is possible to reduce the size of conventional accelerators. This portable machine can provide many medical applications, including cancer treatment. Laser will continue to play an important role in future medicine as long as technology continues to develop.
