Global gastric cancer testing market expected to grow at 5% Compound Annual Growth Rate (CAGR) over 2020 to 2027. Cancer begins in the body when the cells in the body grow without any control. Cells present in any part of the body can develop cancer, which tend to spread to the other parts of the body. Gastric cancer is a type of cancer that starts in the stomach. The gastric cancer is also called as the stomach cancer. The progression of this cancer is slow. The advancement in the growth of the tumor leads serious complications. The treatment depends on the stage of the cancer. The early diagnosis helps in improving the survival rates. Cancer is caused by uncontrolled abnormal cell proliferation that has the ability to spread and invade other sections of the body. Changes in the gene cause a single cell or a few cells to expand and replicate, which is when cancer begins. This could lead to the growth of a tumour, which is an abnormal mass of tissue. The creation of cancer cells in the stomach lining is known as gastric cancer or stomach cancer. Diet and stomach disorders are both risk factors for gastric cancer. Indigestion and stomach pain or discomfort are signs of gastric cancer. The global gastric cancer testing market is expected to develop due to an increase in the incidence of gastrointestinal tumours, lymphoma, and adenocarcinoma, as well as an increase in alcohol use, smoking, and the geriatric population. However, the global gastric cancer testing market is expected to be hampered by tight government regulations and high testing costs.
