Many people think that colorectal cancer is a disease of middle-aged and elderly people, and young people will not get it. Is that true? In fact, young people should also be alert to colorectal cancer, adjust their lifestyle and prevent colorectal cancer. Case story: Xiao Li, 28 years old, has been suffering from mild anemia during her physical examination in recent years. She has no obvious symptoms of discomfort. She thinks nothing should happen, so she doesn't care about it. This year, Xiaoli felt dizzy from time to time and tired at work, so she went to the hospital for treatment. The result of fecal occult blood test was++. The doctor further arranged colonoscopy and finally diagnosed colon cancer. The doctor immediately arranged hospitalization and surgery for Xiaoli. Colorectal cancer is one of the most common malignant tumors in the world, with incidence rate and mortality ranking second and third among all malignant tumors respectively. The incidence rate of colorectal cancer in China is increasing year by year, ranking the third among all malignant tumors. In large cities such as Beijing and Shanghai, the incidence rate of colorectal cancer is higher, and it has jumped to the second place of all malignant tumors. Previous studies have shown that colorectal cancer does occur at a high rate after the age of 50, but in recent years there is a clear trend of rejuvenation of colorectal cancer. Moreover, young people are not as alert to cancer as middle-aged and elderly people, and do not care about the symptoms, so the diagnosis time is late. Compared with middle-aged and elderly people, colorectal cancer in young people tends to have a high degree of malignancy, rapid progress, easy recurrence and metastasis after surgery, and poor prognosis. Although the early warning of colorectal cancer is hidden, there are still clues to follow. Don't ignore it. Intestinal cancer often leads to changes in defecation habits, such as changes in defecation time, more or less stool, changes in stool thickness, diarrhea or constipation. Because of the contact friction between the tumor and feces, the tumor surface breaks and causes bleeding. If the tumor is close to the anus, the blood will be bright red. If the tumor is far away, the blood stool will be dark red, which is often mistaken for hemorrhoids and delays treatment. Because of the growth of the tumor, the feces cannot pass smoothly, which may cause abdominal distension and abdominal pain. In addition, intestinal cancer will lead to long-term chronic blood loss, and patients will show anemia related symptoms, such as dizziness, panic, fatigue, etc. Even if you get colon cancer, don't be afraid. The treatment of colorectal cancer has developed rapidly, including surgical treatment and drug treatment. With the popularization of minimally invasive technology, the proportion of minimally invasive surgery for colorectal cancer is getting higher and higher. Only a few small holes in the stomach can solve the problem. In recent years, there are also robot surgery systems. The emergence of specimen taking surgery through natural cavity has further reduced the surgical trauma and accelerated the rehabilitation of patients. Immunotherapy research has also made rapid progress. For colorectal cancer with unstable microsatellites or missing mismatch repair genes, immunotherapy has significantly improved the survival chances of patients compared with traditional chemotherapy. The prevention of colorectal cancer should start from every bit of daily life, especially young people should not be regarded as the capital of health. First, cultivate a healthy lifestyle. Reduce the intake of red meat and processed meat, increase the intake of fruits and vegetables, take proper intake of nuts and dairy products, and control the intake of sodium; Second, quit smoking and stay away from second-hand smoke; Third, avoid drinking heavily and frequently; Control weight to avoid obesity and diabetes. Those who have obesity or diabetes should lose weight or control diabetes in time; In addition, it is necessary to adapt
