Early Detection and Prevention: Understanding Precancerous Lesions and Common Diseases

[Voice of Hope June 14, 2023](Editor: Li Wenhan) Early detection and early treatment is one of the most effective ways to prevent and treat cancer, and some common diseases in life are actually “precancerous lesions”. What is a “precancerous lesion”? In fact, some pathological conditions that may appear in the body before the occurrence of cancer may develop into cancer after a little development.

It is generally believed that Helicobacter pylori settles and infects after reaching the gastric mucosa through the mouth, causing chronic and superficial gastritis after several weeks or months, and developing into duodenal ulcer, gastric ulcer and chronic atrophic gastritis after several years or decades. Chronic atrophic gastritis is the most dangerous factor leading to gastric cancer.

The most common cause of atrophic gastritis is Helicobacter pylori infection, which is a high risk factor for gastric cancer. Therefore, although it cannot be said that suffering from atrophic gastritis will definitely develop into gastric cancer, people with atrophic gastritis do belong to the high-risk group of gastric cancer. Therefore, once atrophic gastritis is found, everyone must actively treat it, especially those who have Helicobacter pylori infection themselves, so as to prevent atrophic gastritis from continuing to develop into gastric cancer.

Many gastrointestinal cancers evolve from polyps, especially adenomatous polyps of the colon, which have a higher rate of canceration.

A GI polyp is any visible overgrowth of tissue that protrudes from the mucosal surface of the GI tract into the lumen. Polyps include adenomatous polyps, inflammatory polyps, hyperplastic polyps, and neoplastic polyps. As the volume of adenomatous polyps grows, the cancerous rate also increases, and the total cancerous rate is 10% to 20%. Therefore, once a polyp is discovered, even a small adenoma, it should be removed in time.

Clinically, many patients with cirrhosis of the liver are dragged out due to prolonged liver disease. Patients with liver disease often think that asymptomatic is not serious, and that they can be treated or not, or they just take some liver-protecting drugs and let the disease develop, and it is too late to regret when it develops to advanced liver cirrhosis. There are also some patients, although they realize that they must receive treatment, they tend to go to the other extreme and go to the doctor in a hurry. Many patients are stuck in the quagmire of folk remedies and secret remedies and cannot extricate themselves, which not only delays the timing of treatment, but also aggravates the condition. These behaviors are not advisable.

Chronic hepatitis generally has such a development process, “liver disease → liver cirrhosis → liver cancer”, the onset of this process is hidden, and it is generally not easy to detect in the early stage. Therefore, patients with liver disease must pay attention to regular examination and treatment.

Cervicitis is generally divided into acute cervicitis and chronic cervicitis, and chronic cervicitis has a certain relationship with cervical cancer.

Chronic cervicitis is mostly an infection caused by pathogens invading the cervix after childbirth, abortion or surgery. It is not to say that patients with cervicitis will definitely lead to cervical cancer. If patients with chronic cervicitis are persistently infected with high-risk human papillomavirus (HPV), they are prone to cervical cancer. Among them, high-risk human papillomaviruses Symptovirus refers to HPV16 and HPV18.

There are many classifications of enteritis. First of all, I want to emphasize to everyone that not all enteritis will develop into cancer, but if it is chronic ulcerative colitis, everyone must pay great attention to it, because studies have shown that the risk of malignant tumors in patients with ulcerative colitis is significantly increased High.

Many patients with ulcerative colitis do not pay enough attention to their disease. They often take medicine intermittently without regular treatment, treating the symptoms but not the root cause, resulting in recurrent inflammation, which in turn induces canceration. Therefore, for ulcerative colitis, we must pay enough attention to it and carry out regular treatment.

Pancreatitis is also a very common disease. Many people know that acute pancreatitis is “terrible” in pain. But many people don’t know that if pancreatitis is not properly treated and prevented, chronic pancreatitis will form, and finally chronic pancreatitis will recur, causing repeated damage to pancreatic tissue, then the probability of suffering from pancreatic cancer will increase significantly. Therefore, if you find pancreatitis, you must actively treat it, and at the same time take preventive measures in your daily life to prevent repeated attacks of pancreatitis.
