Why Early Detection Of Gastric Cancer Can Save Your Life

Gastric cancer may be the seventh most common cancer in Singapore [1], but most patients are diagnosed at an advanced stage. This may mean that the tumour has already spread to the surrounding lymph nodes. In this case, surgery can still remove the tumour and the affected lymph nodes, but because of the advanced stage, the patient will require chemotherapy after surgery. Sometimes the cancer may be so advanced that it has already spread to other organs in the body like, for example, the liver or the peritoneal cavity. In such cases, surgery can no longer remove all the cancer cells in the body and chemotherapy is used to control the cancer and its symptoms.[2]

In either situation, prognosis is poor when gastric cancer is diagnosed at an advanced stage [3]. That is why although it is the seventh most common cancer, gastric cancer is the fourth cause of cancer death in Singapore.

Early detection can save your life

The only way to improve this situation is for gastric cancer to be detected at an early stage. However, early-stage gastric cancer can have very few symptoms. These symptoms may be subtle and easily confused with common day to day gastrointestinal disorders [4].

Symptoms such as

  • upper abdominal discomfort
  • bloating
  • pain

that does not seem to improve with a short course of medication by the family physician should warrant further investigation including endoscopy of the stomach. Endoscopy is a simple procedure which can be performed under sedation without any discomfort.


When gastric cancer is detected at an early stage, treatment is less invasive and is more effective. The cancer can be removed using endoscopy without the need to remove the stomach. In situations when the cancer is detected early but is not suitable for endoscopic removal, minimally invasive surgery techniques can now be performed to remove part of the stomach with the cancer. The smaller wounds result in less wound pain after surgery with faster recovery. [5]

The Singapore Cancer Society (SCS) is a community-based voluntary welfare organisation dedicated to minimising the impact of cancer through public education, screening, patient services, financial assistance, research and advocacy.

As a self-funded charity, SCS is dependent on public donations to provide quality services to cancer patients, their families and the community at large. SCS was established in 1964, registered as a Society in 1984 and was accorded IPC (Institution of a Public Character) status as a charity in 1995 by the Ministry of Health.
