How high is the incidence of bile duct cancer?

The incidence of bile duct cancer is on the rise worldwide. The cause of the disease is unclear, and it is related to people's neglect of health care and dietary structure. People who eat too much seafood and fish have a higher chance of getting the disease than ordinary people. So, how high is the incidence of bile duct cancer? Let's take a look at the following introduction.

Cancer experts give you the following information on the incidence of bile duct cancer:

In the past two decades, the incidence of bile duct cancer has shown a clear upward trend. In Japan, where bile duct cancer is prevalent, the mortality rate for male patients has increased from 3.3/100,000 in 1972 to 5.3/100,000 in 1992, and for female patients from 3.5/100,000 to 5.3/100,000. The mortality rate has also increased in countries such as Sweden, Finland, and Italy. However, the mortality rate has decreased in women in countries such as Israel, the Netherlands, the United States, Canada, and the Federal Republic of Germany.

Cancer experts say that gallbladder cancer ranks first among malignant tumors of the gallbladder, and others include sarcoma, carcinoid, primary malignant melanoma, giant cell adenocarcinoma, 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.

Cancer experts point out that the incidence of gallbladder cancer has obvious regional differences. In India, Gupta reported that the incidence of gallbladder cancer accounts for 3.6% of all cancers and 31.8% of digestive tract malignancies, while in the United States, it is located after the rectum, colon, pancreas and stomach in digestive tract tumors, accounting for 3% of digestive tract tumors. The incidence of gallbladder cancer in women is 2 to 4 times higher than that in men. It is more common in people aged 50 to 70, and 90% of them are over 50 years old.

The above is an introduction to the incidence of bile duct cancer. I hope it will be helpful to you.
