His wife, Taylor Johnson, announced the news through an emotional Instagram post on Monday, revealing that he passed away at 4:45 pm after a prolonged battle with the disease.

Marcel, who was a father of five, was diagnosed with cancer in August 2025. Throughout his treatment, he had been documenting his health journey and sharing updates with his followers on social media.

His death has once again drawn attention to cancer diagnoses among younger adults and the importance of recognising potential warning signs early.

In an interaction with HT Lifestyle, Dr Vishal Khurana, principal director and head of gastroenterology and hepatobiliary sciences at Metro Hospital, Faridabad, discusses the warning signs of stomach cancer in young adults, the possible risk factors and who may be more vulnerable to the disease.

"Worldwide, stomach cancer rates have actually been falling overall. However, among people under 50, cases are rising in some regions, and these cancers tend to be more aggressive. There is no single clear explanation for this trend yet. Several factors may be contributing to it, including untreated Helicobacter pylori (H. pylori) infection, smoking, diets high in salt, pickled, smoked and processed foods, obesity, alcohol consumption and family history," says Dr Khurana.

He further highlights that delayed diagnosis is another major concern among younger patients. "In young people, symptoms are often dismissed as acidity, indigestion or stress. As a result, the disease may not be detected until it has progressed. Persistent digestive complaints should not always be treated as routine acidity, particularly when they do not respond to standard treatment," he explains.

According to Dr Khurana, stomach cancer can present with symptoms that are easily mistaken for common gastrointestinal problems. However, certain persistent or unusual symptoms warrant medical attention.

Dr Khurana emphasises that persistent acidity should not be managed with repeated self-medication. "My simple advice is that acidity that does not settle with the usual treatment deserves a proper medical check-up, not another antacid. Symptoms such as unexplained weight loss, bleeding, anaemia or difficulty swallowing should never be ignored, regardless of a person's age," he says.

While not all cases of stomach cancer can be prevented, certain lifestyle changes and timely medical interventions may help reduce the risk. Dr Khurana recommends the following precautions:

"People should not ignore persistent symptoms or rely on self-medication for prolonged periods. If warning signs appear, a medical evaluation is essential. Depending on the symptoms and individual risk factors, a gastroenterologist may recommend an endoscopy to investigate the underlying cause," Dr Khurana concludes.
