How is radiation therapy for brain cancer performed?

In recent years, brain cancer has gradually risen again, and brain cancer screening has been elevated to a position that needs attention. Humans are afraid of death, but when it is really irreversible, they are powerless. There are countless people who have died from cancer, and brain cancer is one of the killers. People who are usually very careful and cautious will find symptoms in the early stage, but some people do not have any symptoms in the early stage, so it is best to check regularly. Clinically, it is found that most brain cancer patients have reached the middle and late stages when they show obvious symptoms. Here, we remind the majority of friends who are related to brain cancer to pay attention.

Radiation therapy

Radiation therapy uses radiation or gamma rays or high-speed neutron rays to kill tumor cells.

Radiation therapy is the most common adjuvant treatment for tumors, and is usually started 1 to 2 weeks after surgery. Radiation therapy mainly uses the fact that tumor cells are sensitive to radiation and are easily damaged by radiation to kill tumor cells. Generally, the treatment takes about four to eight weeks, and the size of the irradiation range and the dose are determined based on the different tumor pathological diagnoses, degree of differentiation, and imaging medical examination results. Radiation therapy is an effective method for many malignant tumors and deep benign tumors that cannot be safely removed. Currently, radiation therapy has developed into a form-dependent or positioning method, including linear accelerator radiation therapy, gamma-ray positioning radiosurgery, photon knife, etc. However, some malignant brain tumors still require large-scale brain radiation therapy or whole-skull and spine radiation therapy.

A study published by Texas Anderson Cancer Center in 2008 pointed out that patients who undergo stereotactic radiosurgery (SRS) and whole brain radiation therapy (WBRT) have greater side effects and risks of damage to their learning and memory.

The above is a brief introduction to "How to conduct radiotherapy for brain cancer?" For people who are related to the pathogenic factors of brain cancer, it is recommended to take preventive measures for brain cancer and carry out specific treatment according to the doctor's instructions. I hope that patients can recover soon! If you have other questions about brain cancer, please consult our experts online or call for consultation.
