What are the early symptoms of cardia cancer?

Like other tumors, the cause of cardia cancer is unknown. It may be related to dietary factors, environmental factors, genetic factors and Helicobacter pylori infection. In addition, there are precancerous changes such as chronic atrophic gastritis, gastric ulcer, gastric polyps, gastric mucosal epithelial cell metaplasia and gastric mucosal epithelial dysplasia. The early symptoms of cardia cancer are also very strange!

There are two situations in which the early symptoms of cardia cancer appear: 1. If it occurs in the lower esophagus, the already narrow cardia will become narrower, so it is easy to have symptoms very similar to esophageal cancer; 2. If it occurs in the body of the stomach or the head of the stomach, there are generally no subjective symptoms in the early stage. In the early stage, there is a strange feeling or severe pain when food passes, or a slight heart pain.

The above symptoms can be felt when swallowing, and when swallowing harder food, it feels like it is falling directly into the stomach. This is especially true when drinking hot or cold liquids, and the first mouthful is the most obvious. If you have cancer, once the above symptoms appear, they will always exist. Non-cancer patients with similar symptoms will have these symptoms that appear and disappear, not regularly, and with varying degrees of severity. Symptoms of worsening include difficulty swallowing, a heavy feeling in the abdomen, stomach pain, nausea, vomiting, and gradual weight loss.

The symptoms of mid-stage cardiac cancer are between those of early and late stages, and are progressive. The most widely accepted view is that cardiac cancer originates from the cervical stem cells of the cardiac gland, which can form adenocarcinomas with characteristics of the cardiac or glandular epithelium due to their multidirectional differentiation potential.

Most of the light microscopy, electron microscopy and histochemical studies of cardiac cancer have found that they are mixed types, which is a strong support for this view. Atypical hyperplasia is a precancerous lesion of cardiac cancer. It is also a key pathological process shared by the above-mentioned ulcers, polyps, and atrophic gastritis related to the onset of cardiac cancer. They may become cancerous only when they undergo atypical hyperplasia changes, and most of the colonic metaplasia has the nature of atypical hyperplasia.

This is all about the early symptoms of cardia cancer. I hope the above content can help you. If you have other questions, please consult online experts!
