Can water pollution cause liver cancer? Five symptoms indicate the arrival of liver cancer

In recent years, the increase in hepatitis B patients has also led to an increase in liver cancer patients. According to statistics, liver cancer is the second most common cancer in China, second only to lung cancer in terms of prevalence. The early symptoms of liver cancer are not very obvious. What are the symptoms of liver cancer? What is the cause of liver cancer?

What are the factors that cause liver cancer?

1. Causes of liver cancer: Long-term consumption of pickled, fried, and smoked foods can induce liver cancer, so in daily life, we should try to reduce the consumption of pickled, fried, and smoked foods such as pickled meat, grilled meat, grilled sausages, salted fish, and pickles.

2. Causes of liver cancer: Polluted drinking water: Polluted water may contain excessive bacteria, viruses, industrial toxins, nitrosamines, heavy metals, organochlorine pesticides, etc., which are also causes of liver cancer. Long-term drinking of water contaminated by polychlorinated biphenyls, chloroform, etc.

3. Eating moldy food can also induce liver cancer: Studies have found that moldy food will produce a toxic metabolite called aflatoxin in its mold, and aflatoxin is the strongest biological carcinogen discovered today. Therefore, people should avoid eating moldy foods such as moldy peanuts, corn, rice, dried potatoes, dried radishes, dairy products, soy products, etc.

4. Trace elements that cause liver cancer: areas with low selenium levels are an important factor in the occurrence and development of liver cancer. The selenium content in serum is negatively correlated with the occurrence, and the incidence of cancer is high.

5. Causes of liver cancer: Heavy drinking: Temporary excessive drinking has a significantly higher risk of liver cancer than non-drinkers. Alcohol poisoning can cause alcoholic fatty liver, alcoholic hepatitis, and alcoholic cirrhosis. In alcoholic hepatitis or cirrhosis, the number of Kupffer cells decreases, which can increase the incidence of liver cancer.

Five symptoms indicate the arrival of liver cancer

1. Weight loss and fatigue

This symptom often occurs in the middle and late stages of liver cancer. It may be that tumor metabolites cause changes in the body's biochemical metabolism, reduce food intake, and in severe cases, cachexia

2. Fever

The fever caused by liver cancer is generally around 37.5'C~38℃, occasionally reaching above 39℃, with irregular fever pattern, often without chills. Fever is more common in the afternoon, and sometimes remittent high fever can also be seen. Fever can be caused by tumor necrosis or its metabolites.

3. Digestive tract symptoms

Common symptoms include decreased appetite, upper abdominal fullness after meals, or even nausea, vomiting or diarrhea.

4. Pain

This is a common symptom of liver cancer patients. The pain is usually located in the liver area. The pain in the liver area of ​​patients with mid-to-late stage liver cancer is usually located in the right rib or under the xiphoid process. The nature of the pain is mostly persistent dull pain, dull pain or stabbing pain. A small number of patients may also have special manifestations of pain. Patients with liver cancer may also have referred pain in other parts of the body. The pain area of ​​some patients is located in the upper and middle abdomen. Most of them are caused by left lobe liver cancer, but sometimes they are misdiagnosed as stomach problems and delayed treatment. Some patients may have right shoulder pain, which is more common in clinical practice in tumors near the diaphragm of the right lobe. Because it involves the diaphragm and causes referred pain in the right shoulder, it is easy to be misdiagnosed as frozen shoulder. When liver cancer metastasizes to other parts, symptoms of metastatic lesions will appear. When it metastasizes to the lungs, chest pain may occur; when it metastasizes to the bones, bone pain may occur. Therefore, when liver cancer patients have chest pain or bone pain, it should be considered that it is caused by liver cancer metastasis.

Clinically, a small number of patients may experience sudden severe pain in the liver area, which is mostly caused by rupture and bleeding of cancerous nodules located on the surface of the liver. If the patient is also accompanied by dizziness, blurred vision, palpitations, and low blood pressure, it mostly indicates that the cancerous nodule has ruptured and is complicated by severe internal bleeding. If this happens, emergency rescue should be carried out in time.

5. Other symptoms

Patients with hepatitis, cirrhosis or invasive tumor growth that causes liver decompensation may have a bleeding tendency, such as nosebleeds, gingival and subcutaneous ecchymosis, etc.; hypoproteinemia may also occur, leading to edema, ascites, abdominal distension, etc.
