Most patients say that even if the painful treatment is very effective, it is often difficult to stick to it. So when patients choose a treatment plan, the first look at the effect, the second is an intuitive feeling of their own. The director also said, “Does it hurt like radiation therapy? How do I know that radiotherapy is working here? There are too many patients asking such questions, and often we are very busy and need to communicate with patients about more important treatment issues. In this regard, in order for patients and doctors to maximize each other’s time, it was decided to make a simple science for everyone, just like the director said, “The most asked questions by patients are the ones we didn’t do well”! 1.The specific process of radiotherapy Before entering the treatment room, you will need to change your clothes. While the treatment itself will only take a few minutes, the installation of the molds and your positioning on the machine may take longer and the treatment may last 15-20 minutes. The treatment room room will be in a semi-dark state. A thick metal shield similar to lead will be placed between the machine and the untreated body part to protect your body. A rubber-like material or special wax may also be placed on your skin to ensure that the skin is exposed to the radiation dose accurately calculated by the computer. When you and the machine are in the correct position, the technician will go to an adjacent room to operate the machine. You will be alone in the treatment room, but can talk to the technician through the intercom and they will be able to see you through the TV screen or window. You will be able to breathe normally during the treatment, but to ensure the effectiveness of the treatment, you will need to remain as still as possible while the machine is working. If the treatment needs to be done from different angles, the technician will move the machine several times. You need to remain still while the machine is rotating on the treatment table. The technician will tell you when you can move. If you feel uncomfortable, please tell the technician in time. 2.Does it hurt during the process Generally speaking, radiotherapy is painless. During the treatment, you will not see or feel anything except the humming of the machine. Waiting for radiation therapy to start may be difficult, you can do some activities to distract yourself or pass the time. The radiation machines are large and may be a little scary for you to see for the first time. Some people are a little afraid of radiation therapy when they first start treatment, but once they get to know the medical staff and become familiar with the procedure, their nervousness, anxiety and fear will be much lessened. 3.How do I know the radiation therapy is working? Cancer cells start to die during the radiation therapy, and the process may last for weeks or months after the treatment is over. You will need to have a follow-up appointment or other tests after radiation therapy. The diagnosis and test results will tell you if the cancer is gone, but sometimes the cancer can come back in the same area of the body or in a different area, so the results may not be confirmed for some time after treatment is finished. If palliative treatment is given with radiation therapy, relief of the associated symptoms is a sign that the treatment is working, which again may take a few weeks.
