Life fighting cancer [Effects of shocking experiences experienced by childhood cancer survivors on the human body] I developed osteosarcoma (10 years old) about 40 years ago. At that time, surgical treatment for cancer patients was the main treatment, but now it extends to physical treatment, mental care, and care for the families who support childhood cancer survivors. It has been studied and found that such care is very important and is indispensable from the viewpoint of the cause of the onset of sequelae. Since I am a childhood cancer survivor, I am actually experiencing the fierce family situation at the time of the onset of cancer, my own mental and mental disorders, so I will talk about my own experience. Can be done. From the next time onward, we will post about PTSS [post-traumatic stress symptoms].
