When it comes to tumor, I believe no one will like it, but you have to admit that sometimes it is really far away from us, but sometimes it is very close to us, so it is more positive to do some understanding and let yourself to prevent it than to avoid it. Today, I am going to tell you about a tumor with low incidence – gallbladder cancer. You may feel from the name that you seldom hear about it. However, it is the first malignant tumor of gallbladder: sarcoma, carcinoid tumor, giant cell adenocarcinoma, etc. What kind of gallbladder cancer? The gallbladder, located behind the liver under our right rib cage, has the function of storing and concentrating bile. Gallbladder cancer mostly occurs in women and usually has no obvious symptoms in the early stage, some of them have the symptoms of chronic cholecystitis. Of course, gallbladder cancer is also associated with benign gallbladder diseases and often coexists with stones, and it is generally believed that the chronic irritation of stones is the main factor leading to gallbladder cancer. Since it is difficult to diagnose gallbladder cancer in early stage, once obvious symptoms appear, it is mostly in middle and late stage, therefore, when chronic gallbladder disease exists, it is important to pay attention to regular examination. Early symptoms of gallbladder cancer Although there are no specific symptoms in early stage of gallbladder cancer, there are traces for gallbladder cancer in combination with chronic diseases of gallbladder, so pay attention to gallbladder when the following symptoms exist: 1. pain in right upper abdomen: since gallbladder cancer coexists with gallbladder stones, the symptoms between the two are similar, mostly persistent pain in right upper abdomen, which may have paroxysmal intensification radiating to right shoulder or even waist and back. 2, indigestion, because the bile of gallbladder is involved in digestion, most of the gallbladder cancer patients in the early stage will show signs of small flower, not like greasy, vomiting, belching, and eating without adding. It is caused by the insufficient function of gallbladder to digest fatty substances. 3.Jaundice, the symptom of jaundice mostly appears in the late stage of gallbladder cancer, of course, a small number of patients can also appear in the early stage of gallbladder cancer. It may become persistent, progressive aggravation or intermittent attacks. It is caused by obstruction caused by tumor invasion of bile duct. It is mostly accompanied by wasting, weakness, yellow staining of skin and mucous membrane, as well as itching of skin and other symptoms. 4.Fever and mass: When patients have chills and fever as well as palpable right upper abdominal mass, they are mostly in advanced stage. Given that the early detection rate of gallbladder cancer is not high, it is recommended to have regular checkups for chronic diseases of the gallbladder if they meet the following points: 1. patients with gallstones for more than 5 years; 2. female gallbladder stone patients over 50 years old; 3. patients with gallbladder stones larger than 2 cm in diameter; 4. patients with gallbladder atrophy and thickened wall; 5. gallbladder polyps larger than 1 cm; 6. patients with stones in the neck of the gallbladder The stone is embedded in the neck of gallbladder. If gallbladder cancer is detected at an advanced stage, the surgical resection rate is low and the 5-year survival rate after surgery is less than 5%, therefore, we must pay attention to early prevention and diagnosis and treatment!
