The first section reveals the mystery of tumor
Is precancerous lesion cancer? Don't treat minor ailments as diseases.
Mr. Zhang is a software engineer. He is usually very busy at work, and overtime is common. He often can't eat on time, and often he doesn't have time to eat, so he fools with instant noodles. A while ago, I always felt sick, belching, fullness or dull pain in my upper abdomen, and my appetite was greatly reduced. I went to the hospital and the result was chronic atrophic gastritis. Mr. Zhang didn't take this examination result to heart, because he has suffered from stomach trouble since college, and now he still forgets to eat and sleep as before.
Half a year passed quickly and his symptoms got worse. When Mr. Zhang went to the hospital for another examination, the doctor told him that he had stomach cancer. Mr. Zhang can't believe the facts in front of him. He told the doctor that six months ago, I just had chronic atrophic gastritis. How did it become cancer? The doctor said that chronic atrophic gastritis may be a precancerous reaction. Mr. Zhang said angrily, since I had cancer at that time, why didn't you tell me? Doctors say precancerous lesions and cancer are not the same thing.
Experts answer: Is precancerous lesion cancer?
& ampyacute No, precancerous lesions are not cancer, but they may become cancer if they are not cured for a long time.
There are differences between precancerous lesions and cancer.
Precancerous lesions are neither cancer nor the early stage of cancer. There is an essential difference between the two. Under the long-term effect of different carcinogenic factors, the number of normal cells in the body first increased, but the cell morphology did not change at this time, which was called "simple proliferation" pathologically. Subsequently, with the increase of the number, the difference between the cell morphology and the original tissue cell morphology will gradually increase, and it will enter the precursor stage of cancer, that is, precancerous lesions.
Precancerous lesions must be transformed into cancer under certain conditions. And different tumors, this probability is also high or low. Fortunately, because all malignant tumors have precancerous lesions, if they can be found and treated in time, most precancerous lesions will "pull back from the brink" and turn the corner, and only a few precancerous lesions will continue to develop into cancer. The most common precancerous lesions are as follows: mucosal leukoplakia, mainly oral cavity, digestive tract, vagina and other tissues and mucosal leukoplakia. Chronic gastritis, atrophic gastritis. Cervical erosion, mainly severe cervical erosion. Cystic hyperplasia of breast. Senile solar keratosis. Pigmented xeroderma. Gastrointestinal polyps, especially familial and multiple polyps. Some benign tumors. Once the precancerous lesion is diagnosed, it must be treated actively. Don't let this go, but you should go to the specialist clinic of the general hospital for examination and diagnosis in time and review it on time.
Difference between Precancerous Lesions and Precancerous Symptoms in Popular Science Class
Histologically, it is determined that abnormal lesions may directly develop into cancer and it is not easy to return to normal. This abnormal lesion is called precancerous lesion. Precancerous lesions do not necessarily develop into cancer, but are a sign that the possibility of malignant transformation of lesions increases. This does not mean that all cancers must go through the precancerous stage.
Precancerous state or disease refers to a clinical state with increased cancer risk. In the process of its occurrence and development, there may be some precancerous lesions with canceration potential. For example, atrophic gastritis is not a precancerous lesion, but its gastric mucosa epithelium may have abnormal hyperplasia, the latter is called precancerous lesion, and the former is called precancerous state or disease, which is very important for us to explain the condition for patients.
People susceptible to cancer
Who are the susceptible groups of cancer? Who is easy to get cancer? Cancer is mostly caused by bad diet and living habits, and people with familial and hereditary diseases of cancer are also prone to cancer. The results of long-term research and investigation by American scientists and medical scientists confirm that the following ten kinds of people are more susceptible to cancer! Theoretically speaking, everyone can get cancer, but medical surveys have confirmed that people in the following situations are more likely to get cancer, so we should take preventive measures as soon as possible. Actively preventing cancer is the most effective weapon against cancer.
(1) Be sure to drink very hot strong tea.
Drinking strong tea water with high temperature (above 70 degrees Celsius) often will not only burn the esophagus and form chronic ulcers, but also the tannins in tea will be deposited on the injured parts, which will stimulate the injured esophageal epithelial cells and lead to chronic ulcers that will not heal for a long time and lead to cancer. (2) Cancer cells that often stay up late are formed by mutation during normal cell division. Night is the most vigorous period of cell division. If you don't get enough sleep at night, your immunity will decline, and the mutated cells will not be easily removed in time, which may lead to cancer. People who stay up late often smoke and drink coffee to refresh themselves, and it is easy for more carcinogens to enter the human body. (3) Urine containing one or several carcinogens can stimulate bladder epithelium and make it cancerous. There are many harmful substances in feces, such as carcinogens such as hydrogen sulfide, fecal odor, cholesterol metabolites, secondary cholic acid and so on. If you often stimulate the intestinal mucosa, it will also lead to cancer. (4) Allergy American scientists surveyed nearly 40,000 people. Those who have asthma and are allergic to certain drugs or chemical reagents are more likely to develop cancer than those who are not allergic. Women with allergic history are 30% more likely to develop breast cancer than normal people; Men with allergic history are 40% more likely to develop prostate cancer than normal people. (5) Low serum cholesterol. Some experts in the United States believe that people with low serum cholesterol have a higher incidence of colon cancer. People with serum cholesterol below 1 10mg/dl have a higher risk of colon cancer than normal people. (6) Experts from Harvard University in the United States found that the proportion of people who eat livestock meat such as pigs, cows and sheep every day is 2.5 times higher than those who only eat a small amount of meat several times a month; The risk of pancreatic cancer also increases with the increase of meat intake. (7) Cancer genetics, the children of cancer patients, believes that the occurrence of human cancer has a great relationship with genetic factors, and the risk of cancer in the offspring of cancer patients is significantly higher than that of the general population. (8) The data of one spouse suffering from cancer shows that the phenomenon of both spouses suffering from cancer at the same time or successively is gradually increasing, which is called "marital cancer". Experts believe that the same bad lifestyle is its bane. (9) Hypertension Although hypertension can't directly cause cancer, their pathogenesis is the same. Obesity, alcoholism, smoking and excessive salt will not only raise blood pressure, but also induce cancer. Therefore, active prevention and treatment of hypertension can also reduce the risk of cancer. (10) vitamin deficiency Swiss experts believe that people with less protective vitamins are prone to cancer. People who lack vitamin A and beta carotene have a threefold increase in the risk of lung cancer; Vitamin C deficiency will increase the risk of esophageal cancer and gastric cancer by 2 times and 3.5 times respectively. Among people with vitamin E deficiency, the incidence of lip cancer, oral cancer, skin cancer, cervical cancer, gastric cancer, intestinal cancer and lung cancer will increase.
