Chest pain may also extend to the shoulder and arm. Coughing and hoarseness for more than 6 weeks should be considered as laryngeal cancer, thyroid cancer, esophageal cancer or lung cancer. 2.Abdominal distension and pain, inexplicable abdominal distension should be borne in mind for ovarian cancer. Severe pelvic distention and pain may also be a common symptom of fibroids, ovarian cysts and other reproductive system diseases. In addition, inexplicable stomach pain or bloating after meals may be a sign of stomach cancer. 3.Chronic heartburn Long-term heartburn (heartburn) should be investigated whether it is caused by excessive stomach acid, and then the possibility of esophageal cancer and liver cancer should be investigated. 4.
