What symptom is gastric cancer diffuses

summary

My father-in-law often goes out to socialize and drinks because of his work, so his stomach has been very bad. Recently, his stomachache is getting worse and worse, and his liver and lung are also uncomfortable. We took him to the hospital for examination. The doctor said it was gastric cancer, and it has begun to spread. Let's talk about the spread of gastric cancer.

What symptom is gastric cancer diffuses

First: direct invasion and spread: gastric cancer can directly invade adjacent organs or tissues with lymphatic metastasis. When gastric cancer infiltrates into the gastric wall, it can invade blood vessels and lymphatic vessels and form tumor thrombus. Cancer tissue can also invade the natural lumen, such as the lower end of esophagus, duodenum, omentum, transverse colon, pancreas and liver.

Second: lymph node metastasis: generally according to the order of lymph drainage, from near to far, from shallow to deep, there can also be jumping or metastasis, that is, when there is no metastasis in the near lymph node, the distant lymph node has metastasized. For example, the lymph source of the stomach is connected with the left supraclavicular lymph node, and the cancer cells can be retrogradely transferred to the left supraclavicular lymph node through the thoracic duct, especially called vischow lymph node, indicating gastric cancer It has distant metastasis.

Third: hematogenous dissemination: it mostly occurs in the late stage of gastric cancer, the most common organ involved is the liver, followed by the lung. Once cancer cells enter the circulation, they can form metastases in bone, brain, adrenal gland, kidney, spleen, thyroid and skin. Liver metastases of gastric cancer are mostly metastasized through portal blood, forming multiple nodular metastases in the liver. Sometimes liver metastasis is the first symptom of gastric cancer, and the treatment of intrahepatic lesions is generally poor. Intraperitoneal implantation: gastric cancer invading serosa can fall off to the abdominal cavity and cause implantation. It can be seen in abdominal cavity, mesentery, intestinal wall and pelvic cavity.

matters needing attention

Gastric cancer spread can directly invade the surrounding blood vessels, lymphatic vessels, esophagus, lymph nodes will also have metastasis, to the late stage will cause blood group spread, at this time treatment is also very difficult, so it is recommended that patients find gastric discomfort should be timely treatment, early detection, early treatment, to control the disease as soon as possible.
