What are the early symptoms of lung cancer? The 4 most obvious early symptoms of lung cancer

Digestive tract symptoms: decreased appetite, upper abdominal fullness after meals. Flatulence, indigestion, nausea, etc. are common digestive tract symptoms of liver cancer, among which loss of appetite and abdominal distension are the most common. Diarrhea is also a common digestive tract symptom of liver cancer. It has been reported both at home and abroad. The incidence is high and it is easy to be mistaken for chronic enteritis. Portal hypertension and intestinal dysfunction caused by portal vein or hepatic vein cancer thrombus can cause abdominal distension and increased bowel movements. Abdominal distension can also be caused by ascites.

In life, I believe everyone must be familiar with lung cancer, and its incidence rate is very high. Many people think that lung cancer is a disease that is difficult to cure. In fact, the cure rate of lung cancer is still very high if it is discovered in the early stage. Therefore, we must have a certain understanding of lung cancer, understand its early symptoms, and achieve early detection and early treatment. So what are the early symptoms of lung cancer?

Early symptoms of liver cancer

1. Digestive tract symptoms: decreased appetite, upper abdominal fullness after meals. Flatulence, indigestion, nausea, etc. are common digestive tract symptoms of liver cancer, among which loss of appetite and abdominal distension are the most common. Diarrhea is also a common digestive tract symptom of liver cancer. It has been reported both at home and abroad. The incidence is high and it is easy to be mistaken for chronic enteritis. Portal hypertension and intestinal dysfunction caused by portal vein or hepatic vein cancer thrombus can cause abdominal distension and increased bowel movements. Abdominal distension can also be caused by ascites.

2. Fever: A considerable number of liver cancer patients will sweat and have fever. Most fevers are low to moderate, and a few patients may have high fevers, above 39°C, generally not accompanied by chills. The fever of liver cancer is mostly cancer fever, which is caused by the release of pyrogens into the blood circulation after tumor tissue necrosis.

3. Weight loss and fatigue: Liver cancer patients often feel more fatigued than other tumor patients, which is similar to patients with chronic hepatitis. The cause of fatigue is unknown. It may be due to digestive disorders, nutritional absorption disorders leading to insufficient energy, or liver cell damage and decreased liver function, resulting in metabolic disorders, certain toxins cannot be inactivated in time, or necrosis of liver cancer tissue releases toxic substances. Weight loss is also a common symptom of liver cancer patients, which is due to damaged liver function.

4. Lower limb edema: Patients with liver cancer and ascites often have lower limb edema, which can occur at the ankles in mild cases and spread to the entire lower limbs in severe cases. Clinically, some patients have severe lower limb edema, and fluid can seep out of the thigh skin. The main cause of lower limb edema is ascites compressing the lower limb veins or cancer thrombus blocking them, which obstructs venous return.
