Many people have this question: “I had a polyp a few years ago, why is it now a tumor?”. In fact, many times, tumors are developed from some diseases that we often ignore. In fact, many times, tumors are developed from some diseases that we often ignore, and these minor diseases are what we call “precancerous lesions” in medical science. Because of our indulgence, we give time and space for tumors to develop and finally let them become a big problem. If you see them in the future, you should be careful and take precautions. The first, hepatitis China is one of the areas with a high prevalence of hepatitis B, many people for “hepatitis A”, “hepatitis B”, “big three yang”, “small three yang “These terms are familiar. However, what you may not know is that about 90% of liver cancer patients in China have a history of hepatitis B virus infection. Hepatitis virus causes hepatocellular malignancy mainly by interfering with the replication of DNA (ribonucleic acid) in normal cells and activating oncogenes. Long-term chronic inflammation also causes fibrosis of liver tissues, leading to cirrhosis, which in turn induces liver cancer. Therefore, when you find hepatitis, don’t indulge it and review it regularly, otherwise one day it will be so powerful that you will be helpless. Chronic ulcerative diseases Many young people and office workers often say they have stomach problems, but, very often, they either put up with it and pass, and really can’t put up with it and take some “stomach pills” and get over it. However, this kind of indulgence is really dangerous. Some studies show that gastric ulcer can develop into gastric cancer, and the proportion of gastric ulcer developing into gastric cancer is increasing year by year because of our indulgence. Therefore, when there are irregular episodes of pain or persistent vague pain, the effect of anti-ulcer drugs is not obvious, repeated vomiting of blood, persistent black stools or tarry stools, you should go to the hospital to check the stool occult blood test, a gastroscopy, and possibly a pathological section, to give a conclusion to the “stomach disease”. Third, gastrointestinal polyps Many people know they have intestinal polyps, but few people pay attention to it. However, some polyps can become cancerous! Adenomatous polyps are recognized as precancerous lesions, and the general development time from adenomatous polyps to cancer is about 5~10 years. So, that’s why “I had a polyp a few years ago, but now it’s a tumor?”. Therefore, for people aged 40~50 years old, the time to develop cancer is about 5~5 years. Therefore, for people aged 40-50, if they have never had gastroscopy, it is necessary to check once, and if polyps are found, their nature should be judged, and if they are adenomatous polyps, they should be treated early to eliminate future problems. The majority of patients with chronic atrophic gastritis have no obvious conscious symptoms, sometimes they just feel a sense of fullness, or a vague pain, digestion is not very good. This is why many people ignore it and just take some so-called “stomach medicine” when they have an attack. In atrophic gastritis, the surface of the gastric mucosa is repeatedly damaged, resulting in the atrophy or even disappearance of the intrinsic mucosal glands and the common pathological change of thickening of the mucosal muscle layer. Due to the atrophy or disappearance of the glands, the gastric mucosa has varying degrees of thinning and is often accompanied by intestinal epithelial hyperplasia, inflammatory reactions and atypical hyperplasia, some of which can be carcinogenic. For this reason, if you find any of the above symptoms, you should go to the hospital for relevant examinations and active treatment, and you should not ignore them, as the price you pay will be much higher once the cancer becomes a reality. V. Reflux esophagitis If you often have symptoms of heartburn and regurgitation, or keep coughing badly and have a negative chest examination, you should consider the possibility of gastroesophageal reflux disease. And when suffering from GERD, pay special attention to the presence of Barrett’s esophagus. What is Barrett’s esophagus? It is because gastroesophageal reflux destroys the normal squamous epithelium, which can lead to the formation of a chemoepithelial columnar epithelium that is more resistant to digestive juices, and on the basis of this lesion peptic ulcers, esophageal strictures, intestinal epithelial chemosis heterogeneous hyperplasia, etc. often occur, up to adenocarcinoma. Studies have shown that patients with Barrett’s esophagus have 10-20 times higher risk of developing esophageal cancer than normal people. For this reason, if the above symptoms occur, it is important to consider the possibility of GERD and have a gastroscopy to assess whether there is Barrett’s esophagus, and if so, it needs to be treated actively at an early stage to prevent deterioration. Sixth, cystic hyperplasia of the breast Some female patients often have painful swelling of one or both breasts, and lumps can be felt by touch. The pain is usually more pronounced before menstruation and relieved after menstruation. For this reason, many patients choose to just get over it and let it go. Unbeknownst to them, cystic breast enlargement can greatly increase the chance of breast cancer, and may even be accompanied by breast cancer at the same time. Therefore, patients with these symptoms should be alerted to the possibility of breast cancer. If cystic breast enlargement is found, it should be treated actively and reviewed every 3-6 months, and should not be allowed to develop. Thyroid nodules Often patients say that they feel a hard lump in their neck, but they don’t find anything uncomfortable, so they don’t pay much attention to it, but this lump may be a thyroid nodule. Epidemiological studies have found that thyroid nodules can be found in about 5% of women and 1% of men in iodine-rich areas. Of these many nodules, about 5% to 15% may be thyroid cancer. For this reason, if you find symptoms of appeal, please go to the hospital for a checkup and consider medication or surgery according to the doctor’s judgment, and do not leave it alone. VIII. Long-term human papillomavirus infection of the cervix Human papillomavirus (HPV) infection is one of the high-risk factors for women to develop cervical cancer. Long-term infection will lead to abnormal cell proliferation on the surface of the cervix, which may induce cervical cancer. Therefore, it is recommended that women who are sexually active should undergo HPV genetic testing at the age of 30. If the result is negative, the test should be repeated every 3 years; if it is positive, a cervical smear should also be done and if abnormal cervical cells are found, treatment should be given immediately and not wait. Conclusion: In life we often lack care for our body because of various reasons such as busy work, thus indulging in the development of some diseases that eventually endanger ourselves. For this reason, it is recommended that we should not ignore minor illnesses and pains, as a thousand miles of dike collapses in an anthill, do not leave the disease untreated because it is small. Indulge in the development of disease, which itself is a “disease”!
