Early symptoms of colorectal cancer and gastric cancer

Early symptoms of colorectal cancer and stomach cancer include abdominal pain, indigestion, weight loss, etc. If you find these symptoms, you should seek medical attention in time. Early diagnosis and treatment are the key to improving survival rates.

1. Abdominal pain and discomfort: Abdominal pain is a common early symptom of colorectal cancer and gastric cancer. Colorectal cancer patients may feel dull pain or cramps in the abdomen, while gastric cancer patients may experience upper abdominal discomfort or burning sensation. This pain may be related to the tumor compressing surrounding tissues or causing inflammation. If the abdominal pain persists or worsens, it is recommended to see a doctor for a gastroscopy or colonoscopy as soon as possible.

2. Indigestion: In the early stages of gastric cancer, indigestion symptoms are often present, such as loss of appetite, nausea, and vomiting. Patients with colorectal cancer may experience changes in bowel habits, such as constipation or diarrhea. These symptoms may be related to the tumor affecting digestive function. It is recommended to adjust the diet structure, reduce greasy and irritating foods, increase dietary fiber intake, and take digestive aids when necessary.

3. Weight loss: Unexplained weight loss is a common early symptom of colorectal cancer and gastric cancer. Tumors consume nutrients in the body or affect appetite, leading to rapid weight loss. If the weight drops by more than 5% in a short period of time, it should be taken seriously and relevant examinations should be carried out in time.

4. Other symptoms: Intestinal cancer patients may have bloody stools or black stools, and gastric cancer patients may vomit blood or have anemia. These symptoms indicate possible gastrointestinal bleeding and require immediate medical attention. Some patients may feel weak and tired, which is related to tumor consumption and malnutrition.

5. Diagnosis and treatment: Early diagnosis is the key to improving the cure rate of colorectal cancer and gastric cancer. Common diagnostic methods include gastroscopy, colonoscopy, CT scan, etc. The treatment plan is formulated according to the tumor stage and the patient's condition, and may include surgical resection, chemotherapy, radiotherapy, etc. Surgery is the main treatment for early colorectal cancer and gastric cancer, and chemotherapy and radiotherapy are often used as adjuvant therapy or for advanced patients.

6. Prevention and screening: Regular physical examinations and screening can help detect colorectal cancer and gastric cancer at an early stage. It is recommended that people over 40 years old undergo a gastroscopy or colonoscopy every 1-2 years, especially those at high risk, such as those with a family history, long-term smokers and drinkers. A healthy lifestyle, such as a balanced diet, moderate exercise, quitting smoking and limiting alcohol consumption, can also reduce the risk of disease.

The early symptoms of colorectal cancer and stomach cancer may not be obvious, but once they are discovered, you should seek medical attention in time. Early diagnosis and treatment are the key to improving survival rates. Regular physical examinations, a healthy lifestyle and timely medical treatment can effectively reduce the risk of colorectal cancer and stomach cancer and improve the quality of life.
