Analysis: Can brain cancer be cured by radiotherapy?

Surgery, radiotherapy, and chemotherapy are the three major methods of cancer treatment currently recognized by the medical community. Radiotherapy mainly refers to the use of various rays of different energies to irradiate tumor tissue in order to inhibit and kill cancer cells. Can brain cancer be cured by radiotherapy? Let's take a closer look:

Sixty to seventy percent of cancer patients need to receive radiotherapy during the treatment process, and radiotherapy contributes more than 40% to tumor cure, including radical radiotherapy for early tumors, neoadjuvant and adjuvant radiotherapy before and after surgery, combined radiotherapy and chemotherapy for locally advanced tumors, palliative treatment for advanced patients, etc.
However, most people are familiar with surgery and chemotherapy, but know little about radiotherapy. "The public has a low level of awareness of radiotherapy, and thinks that radiotherapy is only an auxiliary treatment method. People choose radiotherapy when they are desperate, but they have already missed the best treatment opportunity." Experts said that conventional radiotherapy in the past generally had problems such as low accuracy, too large an irradiated area, and difficulty in irradiating enough, resulting in large toxic side effects and poor treatment results. As a result, patients have a misunderstanding of radiotherapy technology and regard it as a last resort. Often, when the cancer is in the middle or late stages and there are no surgical indicators, they will find the tumor radiotherapy department.
Modern radiotherapy technology has achieved precise positioning, concentrated dose in the target area, and eliminated cancer cells without harming surrounding normal tissues. Radiotherapy can not only accurately kill tumor cells, but also avoid the risks of surgery, significantly improving survival rate and quality of life.
