Stage II gastric cancer is in the middle stage, between early and advanced stages. Stage II gastric cancer has infiltrated into the mucosa or submucosa.
Gastric cancer is one of the most common malignancies of the stomach and is associated with peptic ulcers, atrophic gastritis, and prolonged consumption of pickled and smoked foods, but sometimes it runs in families as well. Stomach cancer is generally divided into four stages. Stage I and II generation are early gastric cancer, stage III is progressive gastric cancer and stage IV is advanced gastric cancer. Stage II gastric cancer refers to the tumor has infiltrated into the mucosa and submucosa layer of the gastric wall, but there is local lymph node metastasis beyond 3cm from the primary focus of gastric cancer, or the local tumor has infiltrated into the basal subplasma layer of the gastric wall and there is lymph node metastasis within 3cm from the primary focus, or the tumor has grown into the plasma layer of the gastric wall, but there is no lymph node metastasis. In general, there are no obvious symptoms of early gastric cancer. As the disease progresses, symptoms such as distension and discomfort in the upper abdomen, indigestion, weight loss, and blood in the stool will gradually appear.
Stage II gastric cancer is earlier than stage III or IV gastric cancer, and the treatment effect will be more pronounced than stage III or IV.
