There are two types of initial symptoms. If it occurs in the lower esophagus, the already narrow cardia becomes even narrower, so it is easy to have symptoms similar to those of esophageal cancer; if it occurs in the body of the stomach or on the head side of the stomach, there are generally no conscious symptoms at the beginning, so it is also difficult to diagnose. There is a strange sensation when food passes through, severe pain, a bit of obstruction, and slight heartburn.
Early symptoms of pancreatic cancer: 1. Posterior sternal distension or mild pain. This symptom does not occur continuously, but is intermittent or aggravated after exertion and when eating rapidly.
2.Foreign body sensation when swallowing food. During swallowing, food (especially dry and hard food) passing through the lesion area (the lesion is small) may produce a foreign body sensation, and it is often fixed in one area, and some patients describe the feeling of having something that can never be swallowed. It is easy to be neglected by patients because the symptoms are mild and occur intermittently.
3. Stagnation or stuttering sensation when swallowing. It seems that the patient has the feeling of stagnation and frustration when swallowing food at a certain place for a while.
Intermediate symptoms of pancreatic cancer: Intermediate symptoms of pancreatic cancer are between early symptoms and advanced symptoms, and are progressive in development.
The common symptoms of intermediate stage cardia cancer include moderate cachexia, anemia, edema, generalized failure, metastasis of important organs such as liver, lung, brain and metastasis of abdominal cavity and pelvis, causing pelvic blood, ascites sue bloody ascites, liver failure, coma, gastrointestinal obstruction, etc.
Symptoms during the deterioration period: Anemia, low plasma protein, wasting and even dehydration are seen in patients in the middle and late stages. The presence of abdominal masses, hepatomegaly, ascites signs, and pelvic masses (anal examination) are all signs of inappropriateness for surgery. In advanced cases, in addition to difficulty in swallowing, there may be persistent pain in the upper abdomen and lower back, indicating that the cancer has involved the pancreas and other retroperitoneal tissues, which is a contraindication to surgery. Besides the symptoms of esophageal cancer, there are also all the symptoms of stomach cancer as follows: 1.Swallowing disorder (also when drinking water).
2.Heavy feeling in upper abdomen.
3.Stomach will be painful.
4.Nausea and vomiting.
5.People gradually lose weight.
