How to prevent liver cancer? It’s best to pay attention to two symptoms of liver cancer

Liver cancer is a type of malignant tumor. It refers to a malignant tumor that occurs in the liver, including primary liver cancer and metastatic liver cancer. When people talk about liver cancer, they are mostly referring to primary liver cancer. So how can we prevent liver cancer?

Symptoms of Liver Cancer

1. Digestive tract symptoms and liver symptoms

When patients reach the late stage, digestive tract symptoms are extremely obvious. Lack of appetite and nausea and vomiting make it impossible for liver cancer patients to eat normally, which may be related to the pain, discomfort, constipation, and emotional tension and depression caused by liver cancer. When the tumor stimulates the diaphragm, stomach, and lower esophagus, nausea and hiccups may occur. At the same time, due to the side effects of chemotherapy and other therapies or tumors stimulating the digestive system and nervous system, vomiting, mental depression and other symptoms may occur. Pain in the liver area is the most common symptom of patients with advanced liver cancer. In the late stage of liver cancer, the liver capsule is often infiltrated by lesions, and more severe needle-like or dull and persistent pain in the liver area may occur. When accompanied by rupture of liver cancer nodules, it can cause severe pain, acute abdomen and other clinical manifestations, which is often one of the causes of death from liver cancer.

2. Difficulty breathing and intracavitary effusion

Some patients with liver cancer will experience dyspnea in the late stage, and it is quite serious. There are many reasons for dyspnea in the late stage: ascites, which can lead to decreased diaphragmatic mobility and affect respiratory function; cachexia, which may cause severe pneumonia; lung metastasis of the tumor, lung parenchymal necrosis, respiratory failure, etc. Malignant cavity effusion is an important complication of malignant tumors. In the late stage of liver cancer, malignant cavity effusion occurs in the thoracic and abdominal cavities, peritoneal cavity, pericardial cavity, etc. If not handled properly, it can lead to rapid deterioration and death.

How to prevent liver cancer in daily life

1. Pay attention to drinking water safety

A. Some drinking water is often contaminated by polychlorinated biphenyls, chloroform, etc.; B. Blue-green algae growing in ponds are strong carcinogenic plants; C. Infection with Clonorchis sinensis can stimulate the proliferation of bile duct epithelium and lead to primary bile duct cancer.

2. Pay attention to prevent hepatitis

Experts say that hepatitis is an important factor leading to liver cancer. Using hepatitis vaccines to prevent hepatitis and liver cancer has become one of the most promising ways to prevent liver cancer, but it is estimated that it will take decades to see results. It has been proven that hepatitis B vaccines are effective in preventing hepatitis. However, from a comprehensive perspective, the prevention of HCV and HDV still needs to be considered.

3. Throw away moldy food at home

Especially moldy corn and peanuts, because these foods contain aflatoxin. The metabolite of aflatoxin, aflatoxin B1, can cause liver cancer. It is recommended to eat more fresh food.

4. Pay attention to proper selenium supplementation

To prevent liver cancer, we should also pay attention to proper selenium supplementation. For people with low selenium, selenium-enriched yeast, selenium polysaccharides, selenium-enriched salts, etc. should be used to supplement selenium and increase blood selenium levels.

5. Regular physical examination is the simplest way to detect liver cancer early

Regular physical examinations are recommended, especially for high-risk groups (patients with hepatitis B or C), who should ideally undergo alpha-fetoprotein (AFp) testing or B-ultrasound every six months to check for cancer.
