Gastric cancer is a relatively common gastrointestinal malignancy nowadays, which progresses from early stage to advanced stage in about six months to two years, if relatively fast. But to be precise, there is actually no specific time. Each person has different conditions, different treatment methods, and different biological characteristics of the tumor, and all of them have different progression times. As long as there are uncomfortable symptoms in the stomach, it is recommended to go to the hospital for gastroscopy as soon as possible. If stomach cancer is found, it should be treated by surgery as early as possible to control the progress of the disease, which usually will not develop into advanced stage. Stomach cancer surgery is a relatively mature surgery, even if it is not treated at the first time, post-operative treatment with radiotherapy and chemotherapy as well as combined with Chinese herbal medicine will still have better results. Nowadays, the survival data shows that about half of the progressive gastric cancer can be cured, but of course, it still depends on the individual’s health and condition, and those with good health and strong resistance will recover better.
