” The basics of stomach cancer: the origin and development of the mystery “
Stomach cancer is a serious and dramatic disease. Understanding its origins and development can help us to better understand it and provide a basis for early prevention.
I. Origin of stomach cancer
The occurrence of stomach cancer is a complex process, often beginning with some abnormal changes in episothelimular cells.
Our gastric mucous membranes are like a “ outer coat” to protect our stomachs, and normally the upper skin cells will be replaced in an orderly fashion, with new cells being born to replace older ones and maintaining the health of the stomach mucous membranes.
However, there are a lot of “bad guys” coming to mess up, causing cell anomalies. Among them, the fungus is a “big villain.” It survives in the stomach and releases toxic substances and enzymes that damage the upper skin cells of the gastric mucous membranes and make DNA in the cells more mutagenic. Once DNA has mutated, it’s like the cell’s “command centre” is in a state of disarray, and the cells may grow wildly and uncontrolledly, taking the first step towards cancer.
In addition to the fungus, bad eating habits are also “triggered”. For example, there are many long-term diets of high salt, smoke and pickled foods that contain carcinogens such as nitrite. nitrite can also turn into nitrazine in the acidic environment of the stomach, which is a strong carcinogen that directly strikes the upper skin cells of the stomach mucous membranes and causes cell malformation.
Moreover, genetic factors cannot be ignored. If someone in the family had stomach cancer, the other relatives would have a higher risk of stomach cancer than the average. This is because some mutations of genes may be transmitted by genetic means, allowing future generations to carry with them, from the outset, the “disturbation” of stomach cancer.
II. Development of stomach cancer
As the upper skin cells of the stomach mucous membrane begin to become cancer cells, stomach cancer is on its way to development.
In the beginning, cancer cells may be just “settled” on the surface of the stomach mucous membranes, which is early stomach cancer. At this stage, the extent of the disease is usually small and the symptoms are not evident. Patients may only occasionally feel uncomfortable with the abdominal, or have a feeling of indigestion, which can easily be ignored as common gastrointestinal problems, as many early stomach cancer patients miss out on the opportunity to discover.
Over time, cancer cells will not be isolated, and they will gradually “go” to the lower, mucous and even the membranes of the stomach. Once the limits of the gastric mucous membranes have been broken and immersed in the surrounding tissues, stomach cancer enters a period of progress. At this point in time, the symptoms of the patient, such as more visible pain in the upper abdomen, loss of appetite for food, declining weight and possibly blackness, can no longer be justified.
And there’s one thing cancer cells can do is transfer. They can circulate through lymphs to the lymph knots around their stomachs, which swell up. Further, the blood circulation can run to other parts of the body, such as liver, lungs, bones, etc. Once a remote transfer occurs, the treatment becomes more difficult and the patient ‘ s prognosis becomes poor.
Overall, stomach cancer is a step-by-step process from its origin to its development. With this knowledge, we can devote more attention to prevention in our daily lives, such as the development of good eating habits, active treatment of cholesterol infections, etc. If there are suspicious stomach symptoms, we can go to the hospital in time to detect and cure stomach cancer at an early stage and to protect our health.
