'It's probably something I ate': Why doctors say this common assumption can sometimes delay a cancer diagnosis

Most people have done it.

A burning sensation after dinner? Take an antacid.

Feeling bloated after a weekend feast? Blame the food.

Constipation for a few days? Promise to drink more water and move on.And most of the time, that approach works.But sometimes, the body whispers long before it screams.Cancer is rarely dramatic in its early stages.

It often hides behind symptoms so ordinary that they become part of daily life.

That is why doctors repeatedly stress one thing: it is not the symptom itself that should worry people, but how long it stays, how it changes, and whether it starts behaving differently from what is normal."Almost everyone has reached for an antacid after a heavy meal or blamed bloating on 'something they ate.' Most of the time, these are harmless, everyday digestive complaints that improve with simple lifestyle changes or over-the-counter medications," said Dr Swasthik KS, Consultant - Gastro and Liver Transplant Surgery, KMC Hospital, Mangalore.Yet, he points to a pattern that gastro surgeons often see."Many patients live with these symptoms for months, and sometimes even years, before a diagnosis of stomach, colorectal, or pancreatic cancer finally provides an explanation."The doctor makes an important distinction."The important point is that acidity, bloating, or constipation do not cause cancer.

Rather, in some cases, cancer can present with symptoms that people have become accustomed to ignoring.

The real concern lies not in the symptom itself, but in how it behaves over time."According to the US National Cancer Institute, persistent indigestion, abdominal discomfort and changes in bowel habits can sometimes be warning signs that deserve medical attention, although many non-cancerous conditions can cause them too.Doctors are often less concerned about a single episode of acidity or constipation and more interested in what has changed.Dr Swasthik explained, "For example, acidity that develops for the first time after the age of 45, particularly in someone with no previous history of acid reflux, should not be dismissed if it fails to improve with routine medications.

Instead of repeatedly relying on antacids, further evaluation may be necessary.

In many such cases, an upper gastrointestinal endoscopy can help identify the underlying cause."It is not the occasional bad day that raises concern.

It is when something new becomes the new normal.People often joke about bloating.

Yet doctors pay close attention when it refuses to go away."The medical community needs to investigate persistent bloating because it serves as a medical warning.

The medical field needs to evaluate cases of long-lasting bloating which occurs with early satiety after meals and unexpected weight loss and visible abdominal changes.

The symptoms present a distinct pattern which differs from temporary digestive trouble," said Dr Swasthik.Feeling full after eating only a small amount, unexplained weight loss, and abdominal swelling can occur in several conditions.

In some cases, they may also be associated with cancers involving the pancreas, liver, stomach or colon.

The key word is persistent.People usually notice blood in stools.

But subtle changes often slip under the radar.Dr Swasthik said, "People tend to miss important warning signs when they experience changes in their bowel movements.

A person who develops new constipation or experiences alternating periods of constipation and diarrhea or has stools which become thinner than their usual pattern should consider these symptoms as signs of colon disease.

People should pay attention to the symptoms which continue for more than one week."The US Centers for Disease Control and Prevention notes that colorectal cancer may cause changes in bowel habits, abdominal pain, constipation, diarrhoea and unexplained weight loss.

Sometimes, people may have no symptoms at all.A stool that becomes consistently pencil-thin, constipation that appears out of nowhere, or a feeling that the bowel never empties completely deserves attention, especially if these changes persist.There is one pattern that ties these seemingly unrelated symptoms together."The pattern which connects all of these warning indicators shows that changes need to continue.

Any new digestive symptom appearing after the age of 45 to 50, lasting longer than three to four weeks, failing to respond to standard treatment, or occurring alongside unexplained weight loss, anemia, blood in the stool, or loss of appetite should prompt a thorough medical evaluation," said Dr Swasthik.He adds an important message that should reassure people rather than frighten them."The situation does not require people to feel unnecessary fear about their health because they experience acidity or bloating which can indicate cancer.

The majority of these symptoms arise from common medical conditions which present no risk of cancer.

The financial expense for patients who choose to receive immediate medical treatment proves to be more affordable than the costs which stem from waiting too long to get diagnosed with cancer."This article includes expert inputs shared with TOI Health by:Dr Swasthik KS, Consultant - Gastro and Liver Transplant Surgery, KMC Hospital Mangalore.Inputs were used to explain why seemingly common digestive complaints such as acidity, bloating, and constipation should not always be brushed aside, and why persistent or unusual symptoms warrant timely medical evaluation to rule out serious conditions, including certain cancers.
