In a heartbreaking case that has shocked both the public and medical professionals, a family of four siblings was diagnosed with advanced stomach cancer within just a few years of each other. This tragic situation has raised urgent questions about the role of shared lifestyle habits and genetic risk factors. While the family shared the same bloodline, doctors have pointed out that it wasn’t just genetics that led to this devastating outcome — it was also two deadly common habits that many people still overlook.

The siblings, aged between 38 and 52, grew up in the same household, ate the same meals, and lived a modest life in a rural province. One by one, they began experiencing similar symptoms: persistent indigestion, bloating, weight loss, and fatigue. By the time the first brother went to the hospital, he was diagnosed with stage III stomach cancer. The other siblings followed in the months and years after, each receiving a similar diagnosis.

Dr. Natthapon Veerasak, an oncologist who consulted on the case, said, “At first, we thought this was purely genetic. But when we examined their lifestyle habits, we discovered two shared factors that significantly increased their risk — both of which are disturbingly common in our population.”

Deadly Habit #1: High-Salt, Preserved Food Diet

The first habit was their long-term consumption of salty, pickled, and preserved foods. In many Asian households, these foods are staples — salted fish, fermented vegetables, dried meats. While they may be delicious and convenient, they contain high levels of nitrates and salt, which are known to irritate the stomach lining and can eventually lead to chronic gastritis and stomach cancer.

According to Dr. Natthapon, “Salt doesn’t just raise your blood pressure. Over time, it damages the stomach’s protective lining, allowing harmful substances to penetrate and promote cancer development. Combined with nitrates found in preserved foods, the risk is multiplied.”

Deadly Habit #2: Ignoring Digestive Symptoms and Skipping Checkups

The second critical factor was their tendency to dismiss early symptoms. Like many others, they thought indigestion or stomach pain was a minor issue that could be fixed with antacids or traditional remedies. None of the siblings had ever undergone a gastroscopy — a simple but effective procedure that can detect early signs of cancer.

“Stomach cancer is often called the ‘silent killer’ because it develops slowly and doesn’t show strong symptoms until it’s too late,” Dr. Natthapon explained. “People think it’s just acid reflux or gas. By the time they come in, the cancer has already spread.”

This family’s story is a tragic reminder that cancer is not just about genetics — it’s also about daily habits and awareness. Many people unknowingly share the same two risk factors: consuming high-salt, preserved foods regularly, and ignoring chronic digestive symptoms.

So what can we learn from this case?

Doctors recommend significantly reducing the intake of salty and preserved foods. Fresh vegetables, fruits, and lean proteins should take priority. Moreover, anyone over 40, especially those with a family history of gastric diseases, should consider routine screenings like endoscopy.

In conclusion, the case of these four siblings is heartbreaking, but it doesn’t have to be repeated. Awareness, prevention, and early detection are key. While we can’t change our genetics, we can absolutely change our habits — and in doing so, we just might save our lives.
