Boron Neutron Capture Therapy (BNCT for short), which is effective in the treatment of squamous cell carcinoma, recurrent head or neck cancer and other diseases. 1. Squamous cell carcinoma: It is a malignant tumor of squamous epithelial origin, including squamous cell carcinoma of the lung, squamous cell carcinoma of the esophagus, and squamous cell carcinoma of the eyelid. In these diseases, the use of Boron Neutron Capture Therapy can achieve therapeutic effect through nuclear fission, releasing an extremely strong ability to kill cancer cells. 2. Recurrent head or neck cancer: it refers to a kind of malignant tumor disease that occurs in head and neck tissues, including ear, nose and throat, thyroid gland, etc.. The malignant tumors in these parts are complicated and the condition is easy to recur, so boron neutron capture therapy can be adopted. Through this method, cancer cells can be effectively killed without harming the surrounding healthy tissues. Boron Neutron Capture Therapy is intended for adults and is not suitable for children. During the treatment period, you need to go to the hospital for regular checkups to know how the cancer cells are controlled, and then adjust the treatment plan appropriately.
