(1) The World Health Organization has proposed eight early warning signs of cancer, which are important references for early detection of cancer.
(1) Unexplained bleeding from nose, ear, bladder or intestine, (e.g. nasopharyngeal cancer, bladder cancer, kidney cancer, prostate cancer, colon cancer); (2) Wounds that do not heal persistently, especially wounds that occur on their own without trauma, and swelling that does not subside persistently (e.g. skin cancer, oral cancer, testicular cancer); (3) Abnormal menstruation, heavy bleeding, bleeding outside the menstrual period, abnormal and increased vaginal discharge, especially in middle-aged and elderly women (e.g. ovarian cancer , cervical cancer, endometrial cancer); Liu Xiaofeng, Department of Gastroenterology, General Hospital of Jinan Military Region
④ hard nodes or lumps in any part of the body, such as hard nodes found in the breast, skin and tongue, and lumps in the abdomen, especially those with irregular shape, indicating that they are not smooth and may gradually increase in size, should be paid special attention to (e.g. breast cancer, tongue cancer, skin cancer, liver cancer may show the above symptoms).
⑤ persistent abnormal digestion, which may be accompanied by progressive wasting and poor appetite (e.g. stomach cancer, liver cancer)
⑥significant changes in warts or moles (e.g. malignant melanoma)
⑦ persistent hoarseness (e.g. lung cancer, laryngeal cancer), dry cough (e.g. lung cancer) and difficulty in swallowing (e.g. esophageal cancer, gastric cancer, pharyngeal cancer), burning, pain and foreign body sensation behind the sternum after eating, which may be progressively aggravated (e.g. esophageal cancer, gastric cancer, pharyngeal cancer)
(8) Unexplained weight loss: recent continuous weight loss is a common symptom of most tumor patients (e.g. liver cancer, pancreatic cancer, lung cancer, esophageal cancer, gastric cancer).
(2) The Chinese Academy of Medical Sciences proposed the “ten symptoms” of cancer.
(1) Lumps on any part of the body, such as breast, neck or abdomen, especially if they are gradually increasing in size.
(2) Ulcers on any part of the body, such as the tongue, cheek mucosa, skin, etc., without trauma, especially those that do not heal for a long time.
③Irregular vaginal bleeding or increased discharge (leucorrhea) in women of middle age or older.
④Dullness, burning pain, foreign body sensation or progressive aggravation of dysphagia behind the sternum when eating.
(⑤A dry cough or blood in sputum that does not heal for a long time.
⑥Prolonged indigestion, progressive loss of appetite, and weight loss without identifying a clear cause.
(7) Change in stool habit or blood in stool.
(8) Nasal congestion, epistaxis, severe headache or with diplopia.
(⑨) Sudden enlargement or rupture of the nevus, bleeding, loss of the original hair.
⑩ Painless hematuria.
