Stomach cancer the silent killer. Below are the signs and symptoms

According to the World Health Organization, cancer is the leading cause of death worldwide, killing approximately 9.6 million people. Colon cancer, or colon cancer, is one of the most common types of cancer. In 2018, 1.03 million people were infected and 783,000 died in the same year. It is a disease of concern, especially as it is more common in Asia. In Singapore, colon cancer is the sixth most common cancer among Singaporean men and the eighth most common cancer among women. This means that 1 in 50 men will develop colorectal cancer in their lifetime.

In addition, colon cancer is often asymptomatic in its early stages. Even if these symptoms are present, doctors in particular do not immediately suspect gastritis, because these symptoms are not diagnostic for common diseases that affect the stomach, such as GERD and gastritis. By the time the diagnosis was confirmed, the cancer had already advanced to an advanced stage. Therefore, colon cancer is often referred to as the ā€œsilent killer.ā€

Who is at risk of developing this cancer and what can be done to prevent it? This article will explain everything you need to know.

How does colon cancer develop?
The stomach is part of the digestive system and serves as a food storage facility. It connects the esophagus to the small intestine and aids digestion. Colorectal cancer occurs when cells in the intestinal wall grow and divide without stopping. Eventually, these cells become scaly and inflammatory, and the cancer invades deeply into the colon wall.

What are the signs and symptoms of colon cancer?
As mentioned earlier, pancreatic cancer does not show any obvious signs or symptoms in its early stages. When running, they include:

Pain in the upper abdomen
anorexia nervosa
Unexplained weight loss
Frequent loss of appetite and heartburn
Feeling very full after eating
He was freaking out, and he was screaming the whole time
chronic abdominal pain
Black urine or bloody urine
As you can see, these symptoms are very similar to other situations and are not very unique. Therefore, it is important to consult a doctor if any of the above symptoms appear, especially if they recur.

Who is at risk of colorectal cancer?
You can get stomach cancer if:

Family history of stomach cancer
Most colorectal cancers are sporadic, but about 10% are familial. Studies have shown that people with colon cancer are three times more likely to have a family history of cancer, which is the highest rate in adults except for ovarian cancer.
History of Helicobacter pylori infection
I wrote a more detailed article on Helicobacter pylori, but people with Helicobacter pylori infection are actually more likely to get stomach ulcers and cancer. This risk is greater if you are male and over the age of 55.
Previous history of gastrointestinal lymphoma and gastroesophageal reflux disease
Although most types of polyps do not increase the risk of colon cancer, adenomas can sometimes turn into precancerous polyps.
Chronic chronic gastritis
A diet high in salty and processed foods
Low fiber diet
In addition, men 55 and older who smoke are most at risk.

How is stomach cancer diagnosed in Singapore?
There are several ways to detect colon cancer. I usually do diagnostic tests such as a colonoscopy, endoscopy, and/or CT scan, upper GI series, positron emission tomography, or MRI scan. Gastroscopy allows the patient to see the esophagus, stomach, and upper small intestine. I will also take a biopsy (a sample of a cell) and send it to a lab for cancer screening.

When cancer is diagnosed, diagnostic imaging, such as X-rays, is done to determine the location of the cancer and how far it has spread.
