Liver cancer
Is primary liver cancer contagious?
Primary liver cancer refers to malignant tumors that occur in the liver and are not metastasized from other parts of the body. Such liver cancer itself is not contagious. However, if liver cancer patients have other infectious diseases, transmission may be possible. Most primary liver cancers are related to liver cirrhosis following hepatitis, with hepatitis B being the most common. If accompanied by hepatitis B, it can be contagious, but it usually doesn't spread through regular daily contact. The main transmission routes for hepatitis B are through blood, mother-to-child transmission, and sexual transmission. This means that as long as the patient's blood does not injure someone else, contagion is generally unlikely, so there is no need for excessive worry.
Will Hepatitis B "big three yang" turn into liver cancer?
Patients with severe hepatitis B, if not treated in time or improperly or for an inadequate duration, may progress to develop liver cirrhosis. A portion of those with cirrhosis might then develop liver cancer. Therefore, patients with severe hepatitis B could potentially develop liver cancer if left untreated or not properly treated. Therefore, once diagnosed with hepatitis B, particularly severe forms, prompt and standardized treatment should be sought to achieve an antiviral response against hepatitis B and prevent the occurrence of liver cirrhosis and liver cancer.
The difference between primary liver cancer and secondary liver cancer.
Primary liver cancer generally refers to tumors whose cancer cells originate from the liver itself or from the intrahepatic bile ducts. Secondary liver cancer usually refers to cancer that has metastasized to the liver from other parts of the body, which is the main difference between the two. Additionally, primary liver cancer might progress rapidly, potentially resulting in a short survival time, especially in cases of large, inoperable tumors, where most survival times range from half a year to about a year. In contrast, secondary liver cancer might have a longer survival time, and initial symptoms are generally milder. Also, tumor markers like alpha-fetoprotein (AFP) tend to be higher in primary liver cancer, whereas in secondary liver cancer, this marker may be normal.
How is liver cancer diagnosed?
In clinical practice, if a patient has a history of chronic hepatitis B and imaging tests, such as an enhanced CT or MRI of the liver, suggest a radiological appearance of liver cancer, combined with an AFP level greater than 400 persisting for four weeks, these conditions can support a clinical diagnosis of liver cancer. However, for a confirmed diagnosis, a liver biopsy guided by ultrasound or CT must be performed. The definitive diagnosis of liver cancer relies on identifying cancer cells through pathological examination.
What to do if vomiting occurs in liver cancer?
Liver cancer is divided into two main pathological types, the first being hepatocellular carcinoma, which is the most common, and the other being cholangiocellular carcinoma. Clinically, vomiting is also a common symptom of liver cancer. For symptomatic treatment, we can provide gastric protection and administer antiemetic drugs such as stomach comfort, but these are only symptomatic treatments and do not cure the root cause. The key is still to treat the liver cancer itself, as the symptoms will only alleviate once the cancer is under control. For advanced hepatocellular carcinoma, targeted therapies like sorafenib are available. If it is cholangiocellular carcinoma, and symptoms like vomiting and jaundice appear, which may be obstructive symptoms, then a surgical procedure in hepato-biliary surgery to drain the bile can be performed, which can also alleviate the symptoms of vomiting. (Medications should be used under the guidance of a doctor.)
The difference between primary liver cancer and secondary liver cancer
Primary liver cancer, also commonly referred to as liver cancer, originates in the liver itself and is not transferred from other parts of the body. Secondary liver cancer occurs when the primary tumor originates in another location and then metastasizes to the liver, causing hepatic space-occupying lesions; this is referred to as secondary liver cancer. The main difference between the two types is their origin. Additionally, primary liver cancer is often solitary but may develop intrahepatic or distant metastases as the disease progresses. In cases of secondary liver cancer, multiple intrahepatic metastatic lesions may be discovered at the onset. Moreover, primary liver cancer may often display an elevated alpha-fetoprotein tumor marker, whereas this marker might be normal in secondary liver cancer.
Can primary liver cancer be treated?
Primary liver cancer is also treatable. Generally, if the primary liver cancer is small and has not widely metastasized, surgical resection can be considered, mainly involving hepatectomy and lymph node dissection. Postoperative comprehensive treatment including chemotherapy and radiotherapy is also applied. For primary liver cancer, interventional chemotherapy, as well as methods like cryotherapy, microwave, and ablation can be considered to control the progression of the disease. Additionally, oral targeted therapy such as sorafenib can be used. If primary liver cancer is widely metastasized at the time of detection, there generally aren’t very effective treatment options, and the average survival period might be around six months, with poor treatment outcomes.
Can primary liver cancer patients eat eggs?
Patients with primary liver cancer can also eat eggs, as there are no specific prohibitions against it. Eggs are a high-protein food. While many people worry that eating eggs might increase the burden on the liver, there is actually no need for concern. If a patient has a good appetite and can eat well, consuming some eggs to increase protein intake can help enhance body resistance and support antitumor treatment. In addition to eggs, liver cancer patients should also consume other high-quality proteins such as fish and protein powder. These are all beneficial. Of course, the choice should also be based on the patient's own preferences. Additionally, it is advisable to drink plenty of water and eat fresh vegetables and fruits.
What can people with primary liver cancer eat?
Primary liver cancer, commonly referred to as liver cancer, is a type of malignant tumor of the digestive system. As for diet, there are generally no specific prohibitions. However, it is recommended to stick to a light and easily digestible diet. High-protein foods and high-quality proteins, such as fish, eggs, and protein powder, are very good options. It is best to avoid spicy, pickled, smoked, or grilled foods, as these are not conducive to health. Also, any food that is clearly moldy should definitely be avoided. The main causes of primary liver cancer include infection with aflatoxin and contaminated drinking water, which are two main causes of primary liver cancer. Other causes, like hepatitis virus infections, are also major contributors to primary liver cancer.
Can an MRI detect liver cancer?
Magnetic resonance imaging (MRI) can detect liver cancer. MRI has a high resolution for soft tissues and can multi-dimensionally present the water content and fat content in liver cancer, producing specific signals. MRI can clearly show the size, signal, shape, and the surrounding tissues of liver cancer. It can even detect small liver cancers as tiny as three millimeters and is a preferred method of imaging, more precise than CT.
