Early symptoms of pancreatic cancer are not obvious. According to the census data, the following may be the early symptoms of pancreatic cancer: 1. Foreign body sensation when swallowing food. During swallowing, food (especially dry and hard food) passing through the lesion area (the lesion is very small) may produce a foreign body sensation, and it is often fixed in one part, and some patients describe it as a feeling that they can never finish swallowing. Because the symptoms are mild and occur intermittently, it is also easy for patients to neglect.
2.Obstruction: Continuous mucus spitting, which is caused by the infiltration and inflammation of esophageal cancer reflexively causing increased secretion of esophageal glands and salivary glands, and the accumulation of mucus in the esophagus can cause choking and even aspiration pneumonia.
Pain: persistent dull pain behind the sternum or in the scapular area of the back indicates cancer invasion and peri-esophageal mediastinitis, pain caused by pancreatic cancer can occur in the upper abdomen, which is less likely to be removed by surgery.
4.Bleeding: Patients with esophageal cancer and pancreatic cancer may sometimes vomit blood or stool blood, and the tumor may infiltrate large blood vessels and cause fatal hemorrhage.
5.Heartiness: It is often caused by direct invasion of tumor or metastatic lymph nodes compressing the laryngeal nerve, laryngoscopy can help to diagnose.
6.Weight loss and emaciation: Due to the difficulty of eating, nutrition is getting lower and lower, the patient is emaciated, but generally the patient has appetite. Once anorexia occurs, it is often a sign of extensive tumor metastasis.
7.Sense of chest distension or tightness, often accompanied by dryness in the throat. The patient complains that there is a kind of stuffy phenomenon in the front of the chest, which seems to be blocked by an object and makes the tight feeling in the chest, especially when swallowing food, but it does not affect normal life and work.
