Is gallbladder cancer metastasized to the liver contagious?

Gallbladder tumors are the first among malignant tumors in the gallbladder of the human body. Others include carcinoid, sarcoma, giant cell adenocarcinoma, primary malignant melanoma, etc. Primary gallbladder cancer is relatively rare in clinical practice and has not attracted people's attention for a long time. According to domestic textbooks, it only accounts for about 1% of all cancers. Due to the widespread development of imaging examinations such as B-ultrasound and CT, gallbladder cancer has gradually been recognized and the detection rate has increased. So is gallbladder cancer contagious? The following experts will give you a detailed introduction:

Generally speaking, viruses are contagious, but the infectivity of different viruses varies. After viral infection, only 1% to 1‰ of people develop clinical symptoms, while more people do not develop symptoms and are in a latent infection state. Whether or not a person develops symptoms after viral infection is closely related to the body's defense function. If the body's defense function is strong, even if there is a viral infection, the person may not develop the disease for life. It has been determined that more than 100 viruses can cause more than 30 types of tumors in animals. Some viruses can also cause human tumors. In this way, there is an objective material basis for the possibility of tumor transmission. Viruses or such virus particles have also been found in human Burkitt's lymphoma, nasopharyngeal carcinoma, breast cancer, leukemia, cervical cancer, and melanoma.

In addition, since gallbladder cancer has no specific and typical symptoms in the early stage and is difficult to diagnose, the treatment effect of gallbladder tumors is poor. The main symptoms of advanced gallbladder cancer are right upper abdominal pain, jaundice, a hard mass in the right upper abdomen, and weight loss. The appearance of jaundice indicates that there has been lymph node metastasis and obstruction of the extrahepatic bile duct. The tumor can no longer be surgically removed. Jaundice may also occur if there is combined with stone obstruction. Gallbladder tumors spread directly to the stomach and duodenum, which can cause gastric pyloric obstruction. Gallbladder cancer metastasizes early and widely, with liver metastasis being the most common.

Biological immunotherapy is the fourth new treatment method after surgery, radiotherapy and chemotherapy, and is a powerful supplement to traditional treatment methods. The principle of biological immunotherapy is to extract immature immune cells from cancer patients, use the latest international biotechnology to cultivate them in vitro, and then infuse them back into the patient's body. It can effectively kill tumor cells and stimulate the body to produce anti-tumor immune response. Its important significance is to inhibit the recurrence and metastasis of tumor cells, improve the quality of life of patients, and prolong the survival of patients.

Biological immunotherapy has been recognized as the fourth largest cancer treatment method after surgery, chemotherapy and radiotherapy for its advantages such as safety, effectiveness, no toxic side effects, and ability to significantly improve patients' quality of life and increase survival. It is the most active and promising treatment method in the comprehensive cancer treatment model in the 21st century.
