"British Journal of General Practice" published a study from the University of Keele, UK, which summarized eight key signals of cancer.
The new research host, Dr. Mark Shapley, and colleagues carefully analyzed 25 cancer studies from the United Kingdom, the United States, the Netherlands, Belgium, Australia, Denmark, and Germany, and finally concluded the following "8 key signals of cancer":
1. Rectal bleeding (predicts senile bowel cancer)
2. Iron deficiency anemia (may be a sign of colon cancer)
3. breast lump (may be breast cancer)
4. Rectal examination reveals possible cancer (probable prostate cancer)
5. Blood in the urine (may indicate a cancer related to the urinary tract)
6. Coughing blood (potential lung cancer risk)
7. Postmenopausal bleeding (gynecological-related cancer may occur)
8. Swallowing difficulties (esophageal cancer may occur)
Dr. Shapley said that patients should seek a cancer expert for diagnosis as soon as they have any of these symptoms. The discovery of these key symptoms helps to diagnose a large number of cancer cases early, thereby helping patients seize the opportunity of treatment and improve the cure rate and survival rate. Doctors should determine if a particular cancer is present based on the patient's age and key symptoms. For example, a 21-year-old woman with iron-deficiency anemia is extremely unlikely to have bowel cancer, but if this symptom appears in a 60-year-old man, it is more likely to be a major signal of bowel cancer.
Researchers also say that there are currently more than 200 known cancers, and doctors are unlikely to know all cancers. Therefore, when there is an abnormality in the body, patients must go to the hospital for necessary cancer screening or regular screening. Early diagnosis and early treatment can improve the quality of life of cancer patients.
