Watch out! These eight conditions may be "precancerous lesions".
In fact, some of the pathological conditions that may occur in the body before the occurrence of cancer? 1. Atrophic gastritis-- gastric Cancer Li Xinquan, Chief physician of Hematology and Oncology Department of Tsinghua Chang Gung Memorial Hospital, introduced in the Health Times in 2018 that "several years or decades later, it developed into duodenal ulcer, gastric ulcer, chronic atrophic gastritis and so on. Chronic atrophic gastritis is the most dangerous factor for gastric cancer, and the most common cause of atrophic gastritis is Helicobacter pylori infection. Therefore, although it cannot be said that atrophic gastritis will certainly develop into gastric cancer, people with atrophic gastritis do belong to the high-risk group of gastric cancer. Clinically, many patients with liver cirrhosis are dragged out of liver disease for a long time. Patients with liver disease often think that asymptomatic is not serious, so patients with liver disease must pay attention to regular examination and treatment. "it does not mean that patients with cervicitis will definitely lead to cervical cancer. If patients with chronic cervicitis are persistently infected with high-risk human papillomavirus (HPV).
Cancer, in fact, is not immediately acquired. Depending on the type of cancer, some often take several years or even more than a decade to develop. Therefore, timely detection of "precancerous lesions" is very important.
What is "precancerous lesion"? In fact, some of the pathological conditions that may occur in the body before the occurrence of cancer, "step forward" may develop into cancer.
1. Atrophic gastritis-gastric cancer
According to an article published in the Health Times in 2018 by Li Xinquan, chief physician of the Department of Hematology and Oncology at Tsinghua Chang Gung Memorial Hospital, it is generally believed that Helicobacter pylori arrives at the gastric mucosa through the mouth and then settles down, causing chronic and superficial gastritis weeks or months later. Years or decades later, it develops into duodenal ulcer, gastric ulcer, chronic atrophic gastritis, and chronic atrophic gastritis is the most dangerous factor for gastric cancer.
Liu Bin, a radiologist at Luzhou traditional Chinese Medicine Hospital in Sichuan Province, reported in the People's Daily Health issue in April 2021 that the most common cause of atrophic gastritis is Helicobacter pylori infection, which is a high risk factor for gastric cancer. So although it can not be said that atrophic gastritis will definitely develop into gastric cancer, people with atrophic gastritis do belong to the high-risk group of gastric cancer. Therefore, once it is found that it is atrophic gastritis, we must actively carry out treatment, especially in people with Helicobacter pylori infection.
two。 Gastrointestinal polyps-gastrointestinal cancer
Many gastrointestinal cancers evolve from polyps, especially adenomatous colonic polyps, with a higher canceration rate.

Xia Zhongsheng, chief physician of the Department of Gastroenterology at Sun Yat-sen Memorial Hospital of Sun Yat-sen University, told the Yangcheng Evening News in 2015 that gastrointestinal polyps refer to any visible overgrowing tissue protruding from the surface of the gastrointestinal mucosa into the cavity. Polyps include adenomatous polyps, inflammatory polyps, proliferative polyps and neoplastic polyps. As the volume of adenoma polyps grows, the canceration rate increases, with a total canceration rate of 10% to 20%. Therefore, once polyps are found, even small adenomas should be removed in time.
3. Liver cirrhosis-liver cancer
"clinically, many patients with liver cirrhosis are dragged out of liver disease after a long period of treatment." Jin Yisheng, chief physician of hepatobiliary surgery at Sichuan West China Institute of Hepatology, said in an interview with Zhengzhou Evening News in 2012 that patients with liver disease often think that they are asymptomatic and can be treated or not, or they only take some drugs to protect the liver and protect the liver, allowing the disease to develop. It's too late to regret the development of advanced liver cirrhosis.
Professor Jin Yisheng said that chronic hepatitis generally has such a development process, "liver disease → cirrhosis → liver cancer", this process is concealed and is generally difficult to detect in the early stage. Therefore, patients with liver disease must pay attention to regular examination and treatment.
4. Chronic cervicitis-cervical cancer
Cervicitis is generally divided into acute cervicitis and chronic cervicitis, and chronic cervicitis has a certain relationship with cervical cancer.
Yu Zhuo, deputy director of the Department of Hematology and Oncology at Tsinghua Chang Gung Memorial Hospital, reported in the Health Times in 2018 that chronic cervicitis is mostly an infection caused by pathogen invasion after delivery, miscarriage or surgical injury to the cervix. It has a variety of manifestations, such as cervical erosion, cervical hypertrophy, cervical polyps, cervical gland cysts and cervical valgus. This is not to say that patients with cervicitis will certainly lead to cervical cancer. Patients with chronic cervicitis are prone to cervical cancer if they are continuously infected with high-risk human papillomavirus (HPV). Among them, high-risk human papillomavirus refers to HPV16 and HPV18.
5. Ulcerative colitis-colorectal cancer
There are also many categories of enteritis. Liu Bin, a radiologist at Luzhou Hospital of traditional Chinese Medicine in Sichuan Province, introduced in the People's Daily Health issue in April 2021. First of all, I would like to emphasize that not all colitis will develop into cancer, but if it is chronic ulcerative colitis, we must attach great importance to it, because studies have shown that patients with ulcerative colitis have a significantly higher risk of developing malignant tumors.
Many patients with ulcerative colitis do not pay enough attention to their own diseases, often take medicine intermittently, do not carry out formal treatment, cure the symptoms but not the root cause, leading to repeated attacks of inflammation, and then induce canceration. Therefore, for ulcerative colitis, we must cause enough attention to carry out formal treatment.
6. Chronic pancreatitis-pancreatic cancer
Pancreatitis is also a very common disease, and many people know that acute pancreatitis is painful. Liu Bin, a radiologist at Luzhou Hospital of traditional Chinese Medicine in Sichuan Province, said in the People's Daily Health issue in April 2021 that many people do not know that if pancreatitis is not properly treated and prevented, chronic pancreatitis will occur again and again, resulting in repeated damage to pancreatic tissue, then the probability of developing pancreatic cancer will increase significantly. Therefore, if pancreatitis is found, we must actively treat it and at the same time take preventive measures in daily life to prevent recurrent pancreatitis.
7. Oral ulcer that has not healed for a long time-oral cancer
Ji Qinghai, chief physician of head and neck surgery at the affiliated Cancer Hospital of Fudan University, pointed out in the Health Times in 2015 that long-lasting oral ulcers may be precancerous lesions of oral cancer. In addition, such as mucosal erythema, mucosal leukoplakia, submucosal fibrosis, verrucous hyperplasia and so on may be "precancerous lesions" of oral cancer.
Precancerous lesions such as long-term untreated, or irritants always exist, such as residual roots, dentures, and so on, such lesions are highly likely to turn into oral cancer.
8. Borderline nevus-melanoma
Borderline nevus is more likely to become cancerous than other nevus because it is easy to rub in the palm, foot, vulva and so on. Once it is found that the shape of the nevus is irregular, the boundary is blurred, the color is different, the dizziness or the volume increases slowly, and the skin is slightly raised or thickened, you should see a doctor in time, which is probably the development trend of precancerous lesions.
