In the 1970s, Jiashan County, Zhejiang Province used to be a high incidence area of colorectal cancer. After years of follow-up research and unremitting efforts by medical experts, the county’s colorectal cancer incidence and mortality have dropped significantly.
What is the reason behind the high incidence of colorectal cancer? What are the effective ways to fight colorectal cancer? Let’s see the expert team of the Second Affiliated Hospital of Zhejiang University School of Medicinehow to overcome difficulties.
colorectal cancer high-incidence area
Jiashan

Jiashan County, Zhejiang Province is located in the core area of the Yangtze River Delta urban agglomeration. The first national population death survey data shows that the incidence and mortality of colorectal cancer in Jiashan, Zhejiang are 6 times the national average, ranking first among county-level cities in the country. In the 1970s, Professor Zheng Shu from the Second Affiliated Hospital of Zhejiang University School of Medicine led a team to come here.
After years of research and efforts, the colorectal cancer mortality rate in Jiashan County dropped by nearly 84% compared to the 1970s< /span>. The expert team has also accumulated a wealth of information and data, and finally formed a policy and outline for early screening and early diagnosis of colorectal cancer in my country.
Recognizing Colorectal Cancer
colorectal cancer Also known as colorectal cancer, it is a malignant tumor that occurs in the colon or rectum. In my country, the incidence and mortality of colorectal cancer are increasing year by year. If colorectal cancer is not treated in time, it will lead to complications such as bleeding, perforation, stenosis, obstruction, and tumor metastasis.
Compared with other malignancies, colorectal cancer progresses slowly, especially in the precancerous stage. Therefore, early detection, early diagnosis and early treatment of colorectal cancer is very important.
Colorectal Cancer in Jiashan County
Causes of High Incidence
Long-term Drinking river water containing
carcinogens
hebang water< /span>. Scientists have found that river water contains microcystins, which can damage the liver, gallbladder and intestinal mucosa if consumed for a long time, and cause diseases such as colorectal cancer. With the efforts of the expert team, Jiashan County took the lead in launching a tap water project in Zhejiang Province to improve the quality of drinking water for residents. This has also promoted the development of local follow-up sewage treatment and water source treatment.
Long term consumption
Pickled vegetables and cured meats
width HUU4RwlpGsAjcDM7rB6iapBt4IdN54f5″>< /img> Pickled vegetables and cured meat are very popular among local residents in Jiashan, and they are also common dishes on the table of ordinary people. Sauerkraut and other pickles have high nitrite content, and nitrite will become ammonium nitrite after being absorbed by the human body, which is recognized by the World Health Organization as a carcinogen. Cured meat is processed red meat. Red meat is rich in saturated fatty acids, and excessive intake can affect human health. Cured meat also contains carcinogens such as ammonium nitrite, aromatic hydrocarbons, and heterocyclic amines, which can increase the risk of colorectal cancer. The expert team vigorously promotes healthy eating habits locally, eats more fresh vegetables and fruits, and tries to avoid food containing carcinogens.
Building a Defense System
Fighting Colorectal Cancer
Stool occult blood test
p>fecal occult blood test is an effective method for non-invasive screening of colorectal cancer. Small amounts of bleeding from the gastrointestinal tract due to causes such as inflammation, tumors, or mucosal damage can be found.
Digital Anal Exam
In my country, most colorectal cancers occur in rectal span>, 60% of them occurred in the position where the finger can touch 7-8 cm from the anal verge. A digital anal exam can detect most rectal cancers. In the 1970s and 1980s, colonoscopy was not widely used in my country, and fecal occult blood examination, Digital rectal examination is a very effective method for detecting lesions that can be used by primary hospitals.
60cm Colonoscope
60 cm colonoscopy It arrived, but at that time, it was already a very advanced inspection method. It could see nearly half of the intestines under direct vision, which greatly improved the detection rate of intestinal cancer.
Cure Colorectal Cancer
With “Modern Weapons”
span>With the continuous development of minimally invasive technology, laparoscopy has also developed from plain and high-definition to today’s3D. The operation of the operation is more precise, and the minimally invasive method can help fast recovery.Senior colorectal cancer patientsIt is no longer a surgery surgery off-limits.
With the continuous development of early screening and diagnosis of colorectal cancer in China, a team of medical experts will accumulate a large number of screening tests from Haining and Jiashan, Zhejiang. The experience has been extended to 16 provinces and municipalities across the country. At present, the incidence and mortality of colorectal cancer in Haining and Jiashan areas have dropped significantly, and the incidence and mortality of colorectal cancer in other regions of the country participating in screening have also shown a downward trend. It is expected that in the next 5 to 10 years, the incidence and mortality of colorectal cancer in China will gradually decline.
