The American Cancer Society summarized the physical signs of cancer in the early stages: non-stop coughing, long-term oral ulcers, indigestion, lymph node swelling, hoarseness, sudden weight loss, constipation, diarrhea, bloody stools, and inexplicable pain. \x0d\Signal 1: Coughing non-stop, blood in the sputum\x0d\Be alert to whether it is lung cancer. \x0d\\x0d\Typical signs of lung cancer are irritating cough, blood in sputum, chest pain, etc. About 2/3 have stubborn irritating cough. This kind of irritating cough cannot be alleviated by antibiotics. It usually results in intermittent coughing up bloody sputum or blood-streaked sputum, or a cough with a large amount of foamy sputum, accompanied by laryngeal wheezing, chest tightness, shortness of breath and other symptoms. \x0d\\x0d\If the above symptoms persist for 2 to 3 weeks and do not relieve, it is recommended to seek medical treatment. \x0d\\x0d\Signal 2: Long-term oral ulcers and white spots on tongue\x0d\\x0d\Be wary of oral cancer. \x0d\\x0d\Oral ulcers usually heal on their own within 10 days. Ulcers that do not heal for a long time may be tuberculous ulcers or cancer. If the ulcer is accompanied by repeated bleeding and unexplained numbness, burning, and dryness, and does not heal for more than two weeks, you should be vigilant. \x0d\\x0d\Oral leukoplakia is a precancerous lesion characteristic of epithelial abnormality, which also needs attention. \x0d\Signal 3: Indigestion, dysphagia\x0d\ Be wary of esophageal cancer, stomach cancer, and laryngeal cancer. \x0d\\x0d\If you have long-term unexplained persistent indigestion, you need to consider the possibility of gastric cancer. \x0d\Long-term dysphagia. Substernal pain and foreign body sensation in the esophagus occur when eating. Vegetable leaves, fragments or rice grains are attached to the wall of the esophagus even without eating. After swallowing food, the food will feel as if it goes down slowly or even stay in the esophagus. Within the period of time, you should undergo chest X-ray or gastroscopy as soon as possible. \x0d\Signal 4: Lymph node mass\x0d\Be alert to lymphoma. \x0d\Lymph nodes are immune organs, and swelling is generally related to various types of inflammation. However, if a lump appears, it may be a sign of serious diseases such as lymphoma, AIDS, and tuberculosis. \x0d\If the lymph nodes have been swollen for a short time, feel soft to the touch, and feel pain or tenderness, they are generally benign. \x0d\If the lymph nodes in the neck, armpit or groin remain swollen for a long time, are hard and fixed, have uneven surfaces, no pain or tenderness, and gradually increase in size, you should be alert to the possibility of tumors. \x0d\Signal 5: Hoarse voice\x0d\Be wary of laryngeal cancer and thyroid cancer. \x0d\The early symptoms of laryngeal cancer are atypical and have many similarities with pharyngitis. \x0d\If symptoms such as hoarseness, sore throat, irritating dry cough, blood in the sputum, foreign body sensation in the throat, etc. occur, and symptomatic treatment does not improve, or the symptoms persist for more than 1 month, a detailed laryngoscopy should be performed . \x0d\Thyroid cancer rarely has typical symptoms in its early stages. Hoarseness of the voice is a sign of thyroid cancer, and a B-ultrasound examination of the neck should be performed promptly. \x0d\Signal 6: Sudden weight loss\x0d\\x0d\Be wary of pancreatic cancer, stomach cancer, esophageal cancer, and lung cancer. \x0d\Weight is a "weather vane" of health. If your diet and exercise have not changed, but your weight has dropped by about 10% within one or two months, accompanied by anorexia, diarrhea, constipation, etc., you should be wary of the above-mentioned cancers. However, there are many diseases that can cause sudden weight loss, so it is best to ask a doctor for comprehensive judgment. \x0d\Signal 7: Constipation, diarrhea, blood in the stool\x0d\Be wary of colon cancer and rectal cancer. \x0d\Changes in stool shape, color and defecation regularity are the most direct early manifestations of colorectal cancer. \x0d\For people over 40 years old, if you have loose stools, mucus stools, pus and blood stools, or blood in the stools, which are bright red or jam-colored, and have long-term lower abdominal discomfort, such as abdominal distension, abdominal pain, borborygmire or dull pain, and there is Unexplained anemia, weight loss, weakness, and palpable masses in the abdomen require prompt medical attention. \x0d\However, blood in the stool is a clinically complex symptom, which may also be caused by hemorrhoids, upper gastrointestinal bleeding, etc. If you only find blood in the stool, don't panic, just seek medical attention in time. \x0d\Signal 8: Inexplicable pain\x0d\Be wary of bone cancer and testicular cancer. \x0d\Pain is a symptom of many types of cancer, which is more common in the middle and late stages. Pain may occur in the early stages of bone cancer and testicular cancer. \x0d\The pain in the early stage of bone cancer is characterized by fixedness and persistence, especially at night, and is getting worse day by day. When you feel pain and swelling in your back, limbs, joints, etc., and you cannot find trauma, inflammation, wind and cold, etc., you should be vigilant.

\x0d\\x0d\The pain of testicular cancer is often local dull pain, distending pain, and the pain is not very strong. When you touch the testicles, you can find asymmetry, an increase in the size of the affected side, and a sinking feeling.
