Will eating several kinds of fish raw induce liver cancer? Experts introduce the most effective treatment for liver cancer

Eating several kinds of fish raw can cause liver cancer

Dr. Chamonzo, director of the Cambodian National Center for Parasites, Insects and Malaria Control, said on the 26th that the agency and Japanese researchers have found through collaborative research that eating seven local fish species raw can cause liver cancer.

According to the person in charge, the seven fish are the Indian round-lipped fish, the helmet round-lipped fish, the oblique round-lipped fish and four other carp fish. These fish are distributed in the Tonle Sap River and the Mekong River in Southeast Asia and are freshwater fish that local residents often eat.

Chamenzo told Xinhua that researchers recently discovered a parasite in these fish - liver flukes, which synthesize harmful substances that can inhibit the normal death of human cells and induce tumor growth, leading to liver cancer. He pointed out that eating these fish raw or pickling and fermenting them according to local methods may cause liver flukes to enter the human body and parasitize. The simplest way to prevent it is to only eat cooked fish.

Mut Sinwan, director of the research institute's national intestinal disease prevention and control program, said that eating these fish raw has induced liver cancer not only in Cambodia, but also in Laos, Vietnam, the Philippines, Indonesia and Thailand.

More than half of liver cancer patients in China start with screening to prevent liver cancer

According to the latest epidemiological survey, the number of liver cancer cases worldwide is about 748,000 per year, of which nearly 55% are in China. Experts say that liver cancer can be transformed from chronic viral hepatitis and cirrhosis. Although measures such as hepatitis virus vaccine injection have been taken to reduce the incidence of liver cancer, the incidence of liver cancer remains high due to the rapid mutation of the virus and the existence of immune escape, as well as the emergence of hepatitis C (which has a higher carcinogenicity rate).

Current situation: Liver cancer incidence is gradually getting younger

Experts said that the occurrence of primary liver cancer is related to multiple factors such as viral infection, chemical carcinogens, alcohol, environmental pollution, genetics, etc. In my country, hepatitis B and C virus infection, alcohol and aflatoxin are the most common risk factors for liver cancer.

Which groups of people are at high risk of liver cancer? People with chronic hepatitis B and hepatitis C virus infections, especially those with liver nodules; patients with alcoholic liver disease who drink excessively for a long time; people who like to eat peanuts and other foods that may contain aflatoxin; patients who have liver disease themselves and have liver cancer in their family members, etc. All of the above groups of people are at high risk of liver cancer.

Treatment should be tailored to the patient's individual situation

The treatment of liver cancer should be combined with the patient's physical condition. Liver function is the "capital" of the patient's treatment. Specifically, early-stage liver cancer patients are often treated with surgical resection, while for patients with mid- to late-stage liver cancer, it is necessary to emphasize the combination of multiple treatment methods, including intervention, radiotherapy, chemotherapy and other methods.

It is currently recognized worldwide that surgical treatment is the most effective treatment for liver cancer. If the patient develops the disease in the early or middle stages and has a good liver background, surgical treatment can be considered. For advanced patients, the molecular targeted drug sorafenib is more targeted and can locate the lesion site for treatment without causing too much damage to normal cells. However, the clinical efficacy for advanced cancer patients is not as obvious as expected. For high-risk recurrence patients who have undergone radical surgery, targeted drug therapy is more meaningful for preventing metastasis based on the postoperative pathological response.

Early detection and early treatment can prevent liver cancer

Experts recommend that people at high risk of liver disease should promptly quit smoking and drinking and establish a healthy lifestyle. Generally speaking, if treatment measures are not taken in time, it usually takes about 2 years for liver cancer to develop from cell cancer to natural death. The average time from the onset of cell cancer to the discovery of imaging is about 8 months. If everyone can have regular physical examinations, early detection of liver cancer is possible. Conventional methods include abdominal ultrasound and serum alpha-fetoprotein (AFp) testing. Once an abnormality is found, a more accurate method can be used to confirm the diagnosis. With the development of medical imaging, the detectable liver cancer lesions are getting smaller and smaller. Compared with traditional contrast agents, the new hepatocyte-specific magnetic resonance contrast agent can detect tiny lesions less than 1 cm, which is more conducive to early diagnosis of the disease.
