Clinically, there is a cancer that is almost impossible to detect early, and the vast majority of the nearly 110,000 newly diagnosed patients each year have entered the advanced stage.
Because of its extremely high degree of malignancy, not sensitive enough to radiotherapy and chemotherapy and other treatment methods, so the prognosis effect after entering the advanced stage is extremely poor, patients may die of it in just a few weeks and months, this cancer is also known as the "king of cancer" in the clinic, it is the legend: pancreatic cancer!
The difficulty of early detection of pancreatic cancer is directly related to the specific location and function of the pancreas. Because it is in the deepest part of the upper abdominal cavity, close to the stomach, liver and other organs, the function involves digestion.
Therefore, don't say that it does not have any symptoms in the early stages, even if there are symptoms, patients will often think that they have stomach disease or liver disease, and then ignore the examination.
As everyone knows, if you have the following symptoms in the near future, beware of pancreatic cancer to report the signal:
1. Digestive abnormalities: The pancreas is divided into internal and external double secretion function, its exocrine function is to produce pancreatic juice, and pancreatic juice contains a variety of digestive enzymes, and its function is to neutralize stomach acid, assist the intestine to absorb fat, protein and other substances.
Therefore, when pancreatic cancer develops to a certain stage, patients will appear similar to the performance of chronic gastrointestinal diseases, the most common of which is the obvious decline in appetite, the patient's each meal has a significant decrease, and it is easy to appear nausea, vomiting, bloating and other manifestations after meals.
After eating a large amount of fat or protein foods, diarrhea, constipation and other symptoms can also occur;
2. Abdominal pain: If you often feel inexplicable pain in the upper abdomen recently, manifested as vague pain, dull pain or tingling, and there is no relief after taking drugs for the treatment of stomach disease, painkiller drugs cannot solve the problem, this may be a manifestation of the arrival of pancreatic cancer.
A large number of studies have shown that pain is the most important symptom of pancreatic cancer, whether it is the head or tail of the pancreas, it may produce pain sensations.
This pain is concentrated in the middle and upper quadrants, left and right upper abdomen, and a small number of patients may also have left and right lower abdomen or full abdominal pain;
3. Symptoms of wasting: pancreatic cancer and other malignant tumors are different, because the function of the pancreas is very special, and the development rate of pancreatic cancer is relatively fast, so in the early stage of pancreatic cancer, patients may have cachexia manifestations;
One of the most typical symptoms is the obvious emaciation, in just a few months, patients can lose more than ten kilograms, and sometimes there will be symptoms similar to diabetes, so that patients mistakenly think that they are suffering from diabetes;
4. Jaundice symptoms: any area of the pancreas may become cancerous, the most common of which is pancreatic head cancer.
When the pancreatic head becomes cancerous, the cancer cells will not only infiltrate towards the lower end of the common bile duct, but also the cancer may compress the common bile duct, resulting in bile that cannot be discharged normally into the duodenum;
Progressive jaundice infaction then progresses, and patients may develop yellowing of the face, sclera, and skin and mucous membranes throughout the body, accompanied by abnormal symptoms such as dark yellow urine and clay colored stools.
In addition, some pancreatic cancers also develop symptoms of jaundice after they have advanced stages, which are mostly related to liver metastasis.
As can be seen from the above, the early detection of pancreatic cancer is indeed very difficult, because its symptoms are not typical enough, and it is easy to be confused with liver disease and chronic stomach disease.
Therefore, for people with a family history of pancreatic cancer, a history of acute and chronic pancreatic diseases, a history of obesity and a history of diabetes, etc., the vigilance of pancreatic cancer should be improved, and the doctor should be examined in time after symptoms appear.
