Stomach cancer screening systems aid in the development of a treatment plan. The information needed to assess the stage of stomach cancer can be gathered using the following six tests:

  1. ß-hCG, CA-125, and CEA assays :

The dimensions of ß-hCG (beta-human chorionic gonadotropin), CA-125, and CEA (carcinoembryonic antigen) in the blood can be measured with these tests. These chemicals are released into the circulatory system by both aberrant and healthy cells. They can be an indicator of gastric tumour growths or other problems if they are seen in higher than normal amounts.

2. X-ray of the chest:

An X-ray beam is a sort of energy beam that may pass through the body and onto film, producing images of internal organs. This one is aimed at the internal organs and bones of the chest.

3. CAT or CT scan:

Imagine a computer connected to an X-ray equipment capturing a series of detailed photographs of different places inside the body from various angles. To help the organs or tissues show up more clearly, add dye that can be injected into a vein or ingested.

4. Endoscopic ultrasound:

An endoscope is a thin, lighted tube that is inserted into the body and emits high-energy sound waves (also known as ultrasound) that reflect off inner tissues or organs and produce echoes. The echoes form a sonogram, which is a picture of body tissues. Endosonography is another name for this surgery.

5. Laparoscopy :

Small incisions are created in the abdomen's wall, and a laparoscope — a flimsy, lighted tube — is put into one of the wounds to examine the organs inside and look for symptoms of disease. During a biopsy, various devices may be placed into the same or different incisions to remove lymph nodes or examine tissues.

6. PET scan:

A PET scan is a method that involves injecting a small quantity of coloured sugar into a vein to detect aberrant tumour cells in the body. The PET scanner then revolves around the body on an axis, creating a picture of where glucose is used in the body. Because abnormal tumour cells are more active and take up more glucose than normal cells, they can seem brighter in the image.
