Lesions labeled as gastric body IIa and IIc refer to malignant tumors in the gastric body, meaning cancer in that part of the stomach. These are early-stage gastric cancer classifications, indicating the cancer has not spread to distant organs. IIa describes a superficially elevated lesion, while IIc describes a superficially depressed one.

In an endoscopic examination, early gastric cancer can be divided into protruding type (Type I), superficial type (Type II), and excavated type (Type III). The superficial type (Type II) is further divided into three subtypes based on its visual appearance: superficial elevated (IIa), superficial flat (IIb), and superficial depressed (IIc). These three subtypes account for about 76.8% of all early gastric cancers. Among them, IIc is the most common. Its characteristics are a flat base and a shallow depression, which can disrupt the surrounding mucosal pattern. Type I and IIa are collectively known as the polypoid type, while Type III and IIc are known as the ulcerated type.

IIa and IIc are early-stage gastric lesions, confined to the mucosa and submucosa without distant spread. Their symptoms are often not obvious. Clinical signs may appear as the condition develops and can resemble symptoms of a gastric ulcer or gastritis, such as bloating, dull abdominal pain, vomiting, nausea, acid reflux, indigestion, loss of appetite, fatigue, and black stools or occult blood in stool. Patients experiencing these symptoms are advised to seek timely consultation at a正规 hospital for treatments like surgery and chemotherapy. Regular follow-up checks with abdominal CT scans and gastroscopy are important. Maintaining a calm mindset, eating regular meals, and developing good dietary habits are also beneficial for recovery.
