Liver cancer, that is, primary liver cancer, refers to the malignant tumor caused by hepatocytes or intrahepatic bile duct epithelial cells, which is one of the common malignant tumors in China, and its mortality rate ranks second among malignant tumors.
Liver pain, fatigue, anorexia, and weight loss are the most characteristic clinical symptoms of liver cancer, and most of the patients who come to the clinic once symptoms appear have entered the middle and advanced stages of the disease, and the clinical manifestations of liver cancer at different stages are obviously different.
Pain in the liver area is the most common clinical symptom of liver cancer, which is intermittent or persistent, dull or swollen pain, and is caused by the rapid growth of the cancer and the tightening of the liver capsule. The tumor invades the diaphragm, and pain may radiate to the right shoulder or right back. Tumors that grow backward to the right can cause pain in the right lower back. Sudden, severe abdominal pain and signs of peritoneal irritation suggest subcapsular hemorrhage or abdominal rupture of the cancerous nodule. In addition, gastrointestinal symptoms such as gastric insufficiency, dyspepsia, nausea, and vomiting are easily overlooked due to lack of specificity. Ascites or portal cancer thrombus can cause symptoms such as bloating and diarrhea. A small number of patients in advanced stages may present with cachexia, which is characterized by fatigue, emaciation, and general weakness. Fever may also occur, usually low-grade, occasionally above 39°C, persistent or afternoon low-grade fever or flaccid high-fever. Fever is associated with the absorption of necrotic products from cancer. Sometimes biliary tract infection can be complicated by cancer compressing or invading the bile ducts.
Bitter mouth is a subjective feeling, is one of the manifestations of bad breath, there are many reasons for bitter mouth, such as poor oral hygiene, dry mouth or dehydration, long-term smoking, lack of vitamin B12, zinc and drug factors (rifampicin, captopril, lithium preparations, tumor chemotherapy drugs, etc.), in most cases, bitter mouth has nothing to do with hepatobiliary diseases, and liver cancer will not have bitter mouth symptoms in the early stage.
Colorectal cancer, including colon cancer and rectal cancer, is a common malignant tumor of the digestive tract, colorectal cancer** has not yet been identified, but it may be related to diet and environment (high fat, low dietary fiber), colorectal polyps, chronic inflammation of the large intestine (Crohn's disease, schistosomiasis, chronic amoebic enteropathy, etc.), genetic factors, radiation, nitrosamine compounds, primary and acquired immunodeficiency and other factors.
The clinical manifestations vary depending on the location of the cancer. Chronic progressive intestinal obstruction is prone to occur in left-sided colon cancer, and most patients have intractable constipation, which can also be accompanied by increased frequency of bowel movements, mild or absent vomiting, abdominal distention, abdominal pain, and bowel sounds. When the cancer ruptures, the outside of the stool can be stained with blood or mucus, and even pus may be discharged. Obstruction of the proximal bowel can ulcerate and even cause perforation due to prolonged significant distention, ischemia, and hypoxia. In addition, massive intestinal bleeding and intra-abdominal abscess formation may occur. In the case of right-sided colon cancer, there may be diarrhea, constipation, diarrhea alternating with constipation, abdominal distention, abdominal pain, abdominal tenderness, abdominal mass, and progressive anemia. In the late stage, complications such as intestinal perforation and localized abscess may occur.
Rectal cancer is characterized by increased frequency of stools, thinning of stools with mucus and blood, and tenesmus or a feeling of unclean bowel movements. When the cancer spreads around the rectum and invades the sacral plexus, severe pain may occur. If the cancer involves the prostate or bladder, symptoms such as urinary frequency, urgency, painful urination, poor urination, and blood in the urine can occur, and a fistula leading to the bladder or in women can form.
The diagnosis of colorectal cancer should not only be based on the number of bowel movements, but also refer to other clinical manifestations, combined with tumor markers, digital rectal examination, colonoscopy, barium swallowography, B-ultrasound and other examination methods, and the diagnosis is generally not difficult. Do not judge by yourself and delay diagnosis and treatment.
Gastric cancer refers to malignant tumors originating from the epithelial cells of the gastric mucosa, mainly gastric adenomas. Gastric cancer accounts for more than 95% of malignant tumors of the stomach. Gastric cancer is one of the most common malignant tumors in China, and its incidence varies greatly between different regions, the north is higher than the south, the rural area is higher than the city, the incidence and mortality of gastric cancer in men are higher than those in women, and 55 to 70 years old is the highest incidence age.
Early gastric cancer is mostly asymptomatic, and some patients may have symptoms of dyspepsia. Advanced gastric cancer may present with epigastric pain, postprandial exacerbations, anorexia, anorexia, fatigue, and weight loss. When gastric cancer develops complications or metastasizes, some special symptoms may occur, such as dysphagia, nausea, vomiting, hematemesis or melena, followed by anemia. Metastasis of gastric cancer to the liver can cause right upper quadrant pain, jaundice and/or fever, radiating pain in the back when invading the pancreas, cough, hiccups, hemoptysis when metastasizing to the lungs, and pleural effusion and dyspnea due to pleural involvement. Therefore, there is no significant change in the color of bowel movements in gastric cancer patients, and black stool may appear when ulcerative gastric cancer bleeds.
Changes in stool color can help make an initial diagnosis of the disease and guide further investigations. If the stool is red or the surface is stained with blood, you can consider bleeding close to the location of **, such as fissure, hemorrhoids, rectal polyps, etc.;If it is a black stool, or a black and shiny (tarry stool), you can consider bleeding in a higher position, such as gastric bleeding, duodenal bleeding, etc.;If the stool is bloody or like jam, the possibility of infection can be considered;If it is off-white or clay-like, hepatobiliary disease may be considered. Don't panic because of the abnormal color of the stool, you need a better test to tell.
