The harm of fever caused by gallbladder cancer

What harm can gallbladder tumors cause? In recent years, gallbladder tumors have become a disease that endangers society and human health, and it has brought great distress and pain to humans. So, what are the harms of gallbladder tumors? The following is a detailed introduction to the harms that gallbladder tumors can cause.

What harm can gallbladder tumors cause? 1. Gallbladder stones. Gallbladder cancer is closely related to gallstones. In Europe and the United States, 54.3% to 100% of gallbladder cancer patients have gallbladder stones, while in China, the figure is 20% to 82.6%. From the perspective of gallstones, 1.5% to 6.3% of cholelithiasis patients have gallbladder cancer. Other studies have shown that the risk of gallbladder cancer in patients with gallstones is 4 to 5 times higher than that in patients without gallstones. The earlier the age of gallstone onset, the greater the risk of gallbladder cancer. The risk of gallbladder cancer in patients with gallstones larger than 1 cm in diameter is 10 times greater than that in patients with gallstones smaller than 1 cm in diameter.

2. Chronic cholecystitis Chronic cholecystitis is related to gallbladder cancer. Gallstones, chronic cholecystitis and gallbladder cancer often coexist. Gallbladder mucosa can evolve into carcinoma in situ through metaplasia, hyperplasia or polypoid changes. Studies have shown that the progression time from atypical hyperplasia of the gallbladder to advanced cancer is about 15 years.

3. Gallbladder adenoma Gallbladder adenoma is divided into papillary adenoma, tubular adenoma, and tubulopapillary adenoma. Gallbladder adenoma is characterized by pedunculated and solitary, and is now recognized as a precancerous lesion of the gallbladder. It is generally believed that the canceration rate is about 10%. If combined with gallstones, the risk of canceration increases; if the tumor diameter is more than 10mm, the possibility of canceration is high.

4. Gallbladder adenomyosis Gallbladder adenomyosis is a proliferative disease characterized by hyperplasia of the gallbladder mucosa and muscle layer, forming intramural diverticula, cysts, etc. In the past, it was believed that gallbladder adenomyosis had no possibility of canceration, but in recent years, there have been reports of gallbladder cancer on the basis of gallbladder adenomyosis in Japan, France and other countries.

5. Malformation of the pancreatic-biliary junction Malformation of the pancreatic-biliary junction, that is, the confluence of the pancreatic and bile ducts is a congenital malformation of the digestive system. The most reasonable explanation for the mechanism of abnormal pancreatic duct confluence causing gallbladder cancer is the reflux of pancreatic juice. The mechanism of pancreatic juice causing gallbladder cancer may be that the lecithin in the bile is hydrolyzed by the phosphate A2 in the pancreatic juice to produce defatted lecithin, which has the effect of damaging the cell membrane. It accumulates in the gallbladder wall and stimulates the gallbladder epithelium, causing epithelial cells to degenerate, atypically proliferate and even become cancerous.

6. Animal experiments on industrial carcinogens show that nitrogen toluene, nitrosamines, etc. can cause gallbladder cancer.

7. Female hormones The 3rd National Cancer Survey in the United States found that the age-adjusted incidence of gallbladder cancer per 100,000 population per year was 1.1 for males and 2.2 for females, while in Japan it was 0.7 for males and 1.5 for females. Therefore, some people speculate that this may be related to the estrogen level in the body.

8. The occurrence of other gallbladder cancers is also related to age. Primary gallbladder cancer mostly occurs in middle-aged and elderly people aged 50 to 70. Weight exceeding normal by 20% to 30% can increase the risk of gallbladder cancer. Studies have shown that a body mass index greater than or equal to 24 is a high-risk factor for gallbladder cancer.
