Liver cancer and pancreatic cancer are common malignant tumors of the digestive system in the elderly. Due to the poor responsiveness of the elderly to the diseases, the early symptoms of the diseases are not obvious, and when the diseases are detected, they are already in the middle and late stages, which affects the treatment of the diseases. How to detect liver cancer and pancreatic cancer early for elderly patients? The following warning signs should be highly valued by all. 1. About half of the patients have continuous or intermittent vague pain in the upper abdomen or liver area (lower right chest), while pancreatic cancer sometimes has more intense pain, and the pain can involve the waist and back, and the pain worsens at night. 2. Gastrointestinal symptoms: such as poor appetite, significantly reduced diet, and even nausea and vomiting, which are common symptoms of gastrointestinal tumors. 3. Elderly people have lost weight recently, and their weight can drop 10-20 pounds or more within 1-2 months. The lack of strength (weakness) of the whole body is also a common manifestation of malignant tumor. 4.Yellow eyes and skin, yellow urine, medically called “jaundice”. 5. Other symptoms may include unexplained low fever, with body temperature not exceeding 38 degrees. Diarrhea, abdominal distension, pallor (anemia), etc. may be signs of liver cancer and pancreatic cancer. If elderly people have the above symptoms, especially those who are at high risk, such as those with a history of chronic hepatitis, family members with digestive tract tumors, long-term heavy smoking and drinking, long-term greasy diet, obesity, etc., they should go to the hospital for examination in time. In addition, liver cancer and pancreatic cancer may not have any conscious symptoms in the early stage, so it is more important to have a health checkup, which is recommended 1-2 times a year.
