Many cancers are late stage once they are found. In fact, before the onset of cancer, the body will show many hints, each of which is a chance given by the body to prevent cancer. The 1st signal: long-term fatigue and weakness Mild fatigue ↓ Deep fatigue ↓ Internal variation of organs ↓ Cancer Under normal circumstances, feeling fatigue can be adjusted by taking a good rest, but chronic fatigue that cannot be adjusted for a long time will destroy the body’s immunity and the cancer cells latent in the body will grow rapidly, especially digestive system tumors. A lot of medical research shows that digestive system tumors are closely related to chronic fatigue and constipation. The 2nd sign: persistent cough Cough ↓ lung nodules ↓ lung cancer If pathogenic bacteria are not expelled they will enter the upper whistle and bronchial tubes, and the body activates its defense – coughing to cough out the pathogenic bacteria. And we think that coughing is a disease and immediately take cough medicine and a lot of antibiotics, which presses the pathogenic bacteria that were to be expelled back into the body, so the body’s defense system enters the third step. Occasional coughs are normal, but a cough that is not cured for a long time must be taken care of. When a cough lasts more than two weeks and does not improve with medication, a chest X-ray is recommended to check the lungs. The 3rd sign: indigestion, long-term heartburn Indigestion ↓ gastritis, gastric ulcer ↓ gastric cancer Prolonged and persistent indigestion may be a sign of cancer in the esophagus, throat, stomach, etc. Heartburn is a burning sensation behind the sternum, often occurring about an hour after a meal. If you suffer from heartburn, abdominal pain, stomach ulcer for a long time, which cannot be relieved even after taking pain and acid relieving drugs, pain or fullness after eating, and continuous and gradual loss of appetite, this is mostly an early symptom of stomach cancer or esophageal cancer. The 4th sign: abdominal distension Continuous abdominal distension ↓ pelvic inflammatory disease ↓ ovarian cancer Gastrointestinal symptoms such as abdominal distension and loss of appetite often occur due to the pressure of ovarian tumor. Menopausal women who often feel bloated and have loss of appetite, and no gastrointestinal diseases are found by gastroenterological examination, need to be examined in time at this time. The 5th sign: abdominal pain ↓ chronic pancreatitis ↓ pancreatic cancer Frequent abdominal pain, especially at night, and even more when lying down, and this pain is often difficult to explain. It may be an early sign of pancreatic cancer. Medical data shows that patients with chronic pancreatitis are nearly 100 times more likely to develop pancreatic cancer than normal people. The 6th sign: recurrent oral ulcers Recurrent oral ulcers ↓ white spots on mucous membrane ↓ oral cancer Fixed ulcers on oral mucous membrane (including upper and lower lips, tongue, gums, etc.) that do not heal after 3 to 4 weeks of treatment should be alerted to leukocephalus or even oral cancer. Smokers should pay special attention to the white patches on the mouth and tongue, which may be the precursor of oral cancer – mucosal leukoplakia. The 7th sign: diarrhea, blood in stool Blood in stool ↓ intestinal polyps ↓ intestinal cancer Blood in stool is often confused with hemorrhoids, but it is probably a symptom of intestinal cancer. In addition to blood in stool, if the tumor grows near the anus, it may also show symptoms such as thinner and more frequent stools, and even cause difficulty in stool. Patients with colon polyps should have regular colonoscopy, the purpose of which is to detect early whether the polyps are malignant. The 8th sign: persistent fever persistent fever ↓ weakened immunity ↓ leukemia low fever fever is more common in our daily life, many people will have such symptoms after a cold, but not only the cold will have fever symptoms, some malignant diseases, such as leukemia patients also often have repeated low fever fever phenomenon. Patients with leukemia always have a low-grade fever during the development of the disease, mostly repeated irregular fever, but also patients with high fever of 39℃ or even 40℃ or more. The fever is often accompanied by symptoms of whistling infection such as nasal congestion, runny nose, cough and sputum. Or urinary tract infection symptoms such as frequent and urgent urination, which often cause misdiagnosis. The 9th sign: hematuria Hematuria ↓ bladder tumor ↓ bladder cancer There is no discomfort in the body, but the urine is yellow with blood color, many people think it is “fire”. Unbeknownst to us, this is a danger sign of bladder cancer. Most of the bladder tumors are malignant bladder cancer, but benign tumors are very rare, but whether benign or malignant, they can manifest as painless and visible hematuria. It is easy for patients to take it lightly because there is no pain and other discomfort, and as a result, the treatment is delayed.
