Gastric cancer is one of the leading causes of cancer death worldwide. Because its early symptoms are often not obvious, many patients have already entered the late stage when they are discovered, which makes the treatment of gastric cancer more difficult. However, with the advancement of medical technology, early diagnosis and timely treatment have significantly improved the survival rate of gastric cancer patients.
The importance of early diagnosis
The early symptoms of gastric cancer are often hidden and may only be some stomach discomfort, such as acid reflux, bloating or mild indigestion. These symptoms are easy to be ignored, so regular stomach examinations are essential. Gastroscopy is considered to be the most effective screening method at present, which can help doctors detect early changes in the stomach, such as gastric ulcers, polyps or tumors.
In addition, people at high risk of gastric cancer, such as patients with long-term gastritis, gastric ulcers, family history, etc., should regularly undergo gastroscopy and other auxiliary examinations, such as CT, ultrasound, etc., so as to intervene when the cancer is still in the early stage.
Treatment methods
The treatment of gastric cancer usually includes surgery, chemotherapy, radiotherapy and targeted therapy. Depending on the patient's condition, the doctor will choose the appropriate treatment method according to the stage of cancer and the patient's health status.
Surgical treatment:
For early-stage gastric cancer, surgical removal of the tumor is the most effective treatment. The goal of surgery is to remove the cancerous tissue in the stomach and ensure the patient's gastric function. For some larger tumors, partial or total gastrectomy may be required.
Chemotherapy and radiotherapy:
For patients with advanced gastric cancer who cannot undergo surgery, chemotherapy and radiotherapy are the main treatments. Chemotherapy can kill cancer cells through drugs, while radiotherapy controls the growth of cancer cells through high-energy radiation. The two are often used in combination to achieve better treatment effects.
Targeted therapy and immunotherapy:
In recent years, targeted therapy and immunotherapy have made significant progress. Targeted therapy inhibits the growth and spread of cancer cells by targeting specific molecules of cancer cells; while immunotherapy identifies and eliminates cancer cells by activating the patient's own immune system. Although these new therapies are still under study, they have become an important supplement to gastric cancer treatment.
Prevention and lifestyle changes
Healthy diet: Reducing the intake of high-salt, high-fat foods and increasing the intake of fruits and vegetables can help reduce the risk of gastric cancer.
Quitting smoking and limiting alcohol: Smoking and excessive drinking increase the risk of gastric cancer. Patients are advised to reduce or avoid these two habits.
Regular check-ups: Regular gastroscopy is essential for early detection of gastric cancer, especially for high-risk groups.
