Can a pregnancy blood test detect stomach cancer?

Can a pregnancy blood test detect stomach cancer? The early symptoms of stomach cancer are not obvious and are generally difficult to detect, which makes people worried. Especially pregnant women are very worried. So, can a pregnancy blood test detect stomach cancer? How to diagnose it specifically?

Blood tests can determine whether there are any abnormal indicators in your body. If there is a medical site in your body, then blood tests can determine on a small scale whether this medical site secretes something in the body. This can be detected by blood tests. However, it is impossible to know for sure whether there is a tumor. Therefore, blood tests are not very effective in detecting gastric cancer. In short, blood tests alone cannot completely determine whether it is cancer, including gastric cancer.
To further confirm whether you have gastric cancer, patients still need to go to a regular hospital for some examinations and diagnoses, such as these:
1. X-ray barium meal examination. The application of digital X-ray gastrointestinal contrast technology is still a common method for diagnosing gastric cancer. Air-barium double contrast is often used to make a diagnosis by observing the mucosal phase and the filling phase. The main change of early gastric cancer is abnormal mucosal phase, and the morphology of advanced gastric cancer is basically consistent with the gross classification of gastric cancer.
2. Fiberoptic gastroscopy. Directly observing the location and range of gastric mucosal lesions and obtaining lesion tissue for pathological examination is the most effective method for diagnosing gastric cancer. Using a fiberoptic gastroscope with an ultrasound probe to perform ultrasound detection imaging of the lesion area helps to understand the depth of tumor infiltration and whether there is invasion and metastasis of surrounding organs and lymph nodes.
3. Abdominal ultrasound. In the diagnosis of gastric cancer, abdominal ultrasound is mainly used to observe the infiltration of the stomach's adjacent organs (especially the liver and pancreas) and lymph node metastasis.
