Introduction
Biopsy is a commonly used diagnostic method that provides histological evidence and plays an important role in the definitive diagnosis of early gastric cancer. When a gastroscopic examination reveals abnormalities in the gastric mucosa, the physician will take a small tissue sample for biopsy. If the biopsy results show the presence of malignant cells confined to the mucosal layer or submucosal layer without invasion into deeper muscular layers, a diagnosis of early gastric cancer can be made.

Early gastric cancer can generally be diagnosed through biopsy. It is recommended to seek timely medical attention and undergo examinations under the guidance of a professional doctor to clarify your condition.

Biopsy is a commonly used diagnostic method that provides histological evidence and plays an important role in confirming early gastric cancer. When abnormalities in the gastric mucosa are detected during gastroscopy, a small tissue sample will be taken for biopsy. If the biopsy results show the presence of malignant cells confined to the mucosal or submucosal layer without invasion into deeper muscular layers, a diagnosis of early gastric cancer can be made. In such cases, the biopsy results can directly serve as the basis for diagnosing early gastric cancer.

In addition, imaging examinations, including upper gastrointestinal contrast studies and CT scans, help assess the size, location of the lesion, and whether there is lymph node metastasis, but they have relatively low sensitivity for detecting early-stage lesions. Therefore, they are usually used as auxiliary diagnostic methods rather than definitive diagnostic tools. Blood tests can detect whether serum tumor markers are elevated and whether Helicobacter pylori is present. These tests may provide some diagnostic clues but cannot directly confirm gastric cancer.

If diagnosed with early gastric cancer, professional treatment should be carried out according to the doctor's recommendations, including surgery and chemotherapy. With timely treatment, the cure rate for early gastric cancer is relatively high.

How much does a painless gastroscopy cost?
In general, the reference price for a painless gastroscopy ranges from 800 to 3000 yuan. The specific price is influenced by factors such as preoperative examination items, type of anesthetic used, whether pathological biopsy is included, type of examination equipment, and regional cost of living. Actual pricing is recommended to be confirmed with the local hospital. If a painless gastroscopy is required, it is recommended to choose a formal medical institution.

Is lymphoma a tumor?
In general, lymphoma is a malignant tumor originating from the lymphatic system. Therefore, by definition, lymphoma is indeed a type of tumor. If suspicious symptoms appear, prompt medical evaluation is necessary, with definitive diagnosis established through tests such as pathological biopsy. After diagnosis, appropriate treatment should be selected according to medical advice to avoid delays in managing the disease. During treatment, maintain regular作息 (daily routines), and avoid excessive fatigue.

Can I test for Helicobacter pylori after drinking water in the morning?
Whether drinking water in the morning affects Helicobacter pylori testing depends on the testing method and the amount of water consumed. If undergoing a carbon-13 or carbon-14 urea breath test, drinking a small amount of warm water typically does not interfere with the test, but consuming large amounts of water or beverages containing sugar or additives is not recommended. If undergoing a胃镜活检 (gastroscopy biopsy) or serum antibody test, water consumption has minimal impact on test results, and testing can generally proceed.

What is the normal value for Helicobacter pylori?
There is no unified standard for normal values of Helicobacter pylori, and the interpretation depends on the specific testing method used. Clinically common methods include carbon-13 and carbon-14 urea breath tests, as well as gastric biopsy, each having its own reference range. Results beyond the reference range often suggest possible infection. Before undergoing Helicobacter pylori testing, patients should discontinue medications that may interfere with test results, such as antibiotics and proton pump inhibitors, as instructed.

How much does a cone biopsy of the cervix cost?
Under normal circumstances, the principle of cervical conization is to surgically remove a cone-shaped portion of the cervix to treat conditions such as cervical intraepithelial neoplasia. This procedure uses specialized instruments to precisely remove the diseased tissue while endeavoring to preserve the normal cervical structure and minimize impact on fertility. The general reference price for cervical conization ranges from 8,000 to 22,000 yuan per procedure.
