1, the early symptoms of cancer
1, heartburn Chronic heartburn and mild nausea may be the early manifestations of gastric cancer. If these symptoms are still not relieved after taking antacids, and your appetite is less than usual, and you feel abdominal distension after meals, it is recommended to seek medical advice in time, because this shows that you may have gastroesophageal reflux, which will increase the risk of precancerous lesions of laryngeal cancer.
2. Shortness of breath. Shortness of breath may be a manifestation of lung cancer. If you cough for several weeks, whether it is dry cough or sputum in cough, it may be an early sign of lung cancer. It is recommended to see a doctor in time, take X-rays and have a CT examination.
3. flu-like symptoms. Unexplained fever may mean cancer. Most cancers will have a fever at some stage, usually when the cancer cells have metastasized from their original location to other parts of the body. The early symptoms of lymphoma are particularly similar to influenza, such as persistent fever and pain.
4, hoarse voice. If your symptoms of upper respiratory tract infection have disappeared or the allergic season has passed, but your voice is still hoarse for more than 2 weeks, especially if your symptoms continue to deteriorate, it is recommended to have a check-up. Hoarseness or laryngitis may be the external manifestation of laryngeal cancer, lung cancer and even thyroid cancer. In many cases, hoarseness may also be the only symptom of esophageal cancer.
5, arm pain. If the pain in the arm and the inside of the arm becomes more and more serious as time goes by, it is probably caused by swollen lymph nodes and nerve compression, which is one of the symptoms of lung cancer. This kind of pain is not like muscle ache, but fixed in a certain position, similar to neuralgia or arthritis pain.
6. Abdominal distension. Compared with men, abdominal distension is a common physiological phenomenon in women. However, if it still happens regularly every month except around the menstrual period, especially if you still feel abdominal distension after not eating much, it is recommended to go to the hospital for B-ultrasound and other examinations in time. Because abdominal distension is one of the common symptoms of ovarian cancer.
7. Dysuria. Men with dysuria, whether unable to urinate or urinating less, often take it for granted that it is prostatic hypertrophy. But in fact, dysuria may also be a common symptom of prostate cancer. It is recommended to seek medical attention in time, and the diagnosis can be made through prostate specific antigen and other tests.
8. Fatigue. Weakness and fatigue are symptoms of many cancers, especially leukemia. The American Cancer Society reminds that if you still feel exhausted after getting enough sleep and little pressure, it is recommended to have a general physical examination as soon as possible.
