Cancer, a topic that people talk about, used to be far away from us, but nowadays, he is getting closer and closer to us. Some scientists report that tumor is as common as the flu. As a doctor in the oncology department of a tertiary hospital, most of my contacts are cancer patients. Some people may ask me why I choose this profession, will I feel depressed when I see one by one lives being attacked by cancer and finally taken away by death and you can do nothing about it? My friends around me also tease me that I am the end of life. It is true that cancer treatment is still a process of exploration and research, although there are currently surgery, chemotherapy, radiotherapy and new drug targeted therapy, but for most cancer patients, it is still only to extend their life and improve their life treatment, cancer is a chronic disease, the treatment process is very painful, and some cancer patients may have cancer cells spread and metastasize after discovery, which makes treatment more difficult. It is even more difficult to treat. For most people who do not know much about cancer, having cancer means that they are not far from death, they are very afraid, desperate and helpless inside. Through their eyes, I deeply felt their inner torment and struggle. They desperately hoped that the doctor would tell them that he was fine and could be cured, but I could not afford to give this answer, even if I lied to him, because I deeply felt the horror of treating cancer. Whenever I was asked about this, I would always guide him to think about this disease positively and sunny, and I would explain to them in detail about some patients who survived for a long time after treatment, for example, so-and-so is a nasopharyngeal cancer who is still doing well after 17 years of radiotherapy; so-and-so is a lymphoma who is doing well every time he comes to the hospital for examination after treatment, no different from normal people. I dare not tell them that those advanced malignant cancer can not live long and very painful things, because it is a doctor, I have to save lives and help the injured, I have to see the patients well, I have to care about their hearts, I can not let them even I can not grasp this a life-saving straw. Speaking of which, I deeply feel that I am really helpless as a doctor. What should I do if I already have cancer? Fear, dread, despair and struggle will lead to the collapse of your spirit and willpower. When even the last line of defense of your body has been overcome, cancer cells will devour our body even more recklessly. Therefore, cancer patients should face their illness frankly, be strong, optimistic and confident, adjust their mindset, divert their attention, listen to music more often, and use music to arouse their hope for life, memories of the past, feelings of life, and release of helplessness or bad emotions, while maximizing the improvement of their quality of life. We should pay attention to rest, moderate exercise, avoid fatigue, improve nutrition, diversify and balance the diet, and follow the needs of the disease to improve the immunity of cancer patients and fight against the invasion of cancer cells by “evidence-based diet” according to the weather, climate and living habits. Actively cooperate with the doctor’s treatment, regularly check the body, and dynamically observe the body condition. Adjust your body to the best condition to resist the disease.
