Mistaken for acidity or gallstones: Why pancreatic cancer is often detected late

Pancreatic cancer rarely announces itself loudly. It whispers. It hides behind symptoms that seem ordinary. A little acidity after meals. A dull backache. A feeling of fullness that does not actually go away.Many people dismiss these signs. Doctors treat them as common digestive problems. And, they are. But sometimes, they are not.Pancreatic cancer is among the most serious cancers worldwide. According to the Indian Journal of Medical Sciences, pancreatic cancer cases have been steadily rising in urban regions. Globally, data from the World Health Organisation shows it remains one of the leading causes of cancer-related deaths because it is usually diagnosed late.Why does this happen so often?“Pancreatic cancer is often challenging to detect early, not because it lacks warning signs, but because those signs are subtle and easily mistaken for common digestive issues like acidity or gallstones,” says Dr Ashwani Kumar Sharma, Vice Chairman – Manipal Comprehensive Cancer Centre & Onco Robotic Surgeries, North-West Cluster.The pancreas sits deep inside the upper abdomen, behind the stomach. It does not form visible lumps in the early stages. Instead, it creates discomfort that feels familiar.Dr Sharma explains, “There has been a constant increase in patients with symptoms such as acid reflux, difficulty in digesting, back pain, or a sensitive stomach area, symptoms that are usually linked to gastritis or gallstones. Unfortunately, in some cases, these symptoms can actually be the signs of pancreatic cancer.”A person may take antacids. The burning reduces. The pain eases. Life moves on. And that is where the delay begins.One of the most confusing symptoms is pain in the upper abdomen that spreads to the back.“One of the signs of pancreatic cancer could be a pain in the upper abdominal area that radiates to the back and is considered a gallbladder stone issue,” Dr Sharma notes.Gallstones are common in India. So are digestive complaints. When pain appears in the right upper abdomen, doctors suspect gallbladder disease first. It makes sense clinically. But if scans are delayed or symptoms persist without clear cause, precious time can be lost.The pain may come and go. That makes it even harder to take seriously.Jaundice can also mislead. Many cases of jaundice are caused by gallstones blocking the bile duct. But pancreatic tumours can block the same duct.Dr Sharma points out, “Moreover, a lot of people suffer from jaundice, which is mainly attributed to gallstones.”When yellowing of the eyes appears along with weight loss, loss of appetite, dark urine, or pale stools, the concern should rise. These signs often indicate obstruction of bile flow. In pancreatic cancer, this obstruction may mean the tumour has grown enough to block nearby structures.By this stage, the disease is advanced.The harsh truth is this: pancreatic cancer tends to show clearer symptoms only when it has already progressed.Dr. Sharma explains that by the time “weight loss, persistent pain, jaundice, or weakness become apparent, the cancer may have already progressed to a point where the treatment options are very restricted.”Data from the Frontiers shows that five-year survival rates remain low largely because most cases are diagnosed at stage III or IV. Late detection is not due to ignorance. It is due to biology. The pancreas lies hidden. Early tumours grow quietly. Some symptoms deserve closer attention, especially if they persist beyond a few weeks:Temporary relief with acidity medicines does not always mean the problem is solved. If symptoms return repeatedly or worsen, further tests such as imaging scans or blood tests may be necessary.“If digestive symptoms persist beyond a few weeks, worsen over time, or are accompanied by weight loss or jaundice, further evaluation is essential. The earlier the diagnosis, the effective the treatment can be,” says Dr Sharma.Early-stage pancreatic cancer, though rare, can sometimes be treated with surgery. In selected cases, chemotherapy and radiation are added. Dr Sharma also notes, “Robotic surgery in pancreatic cancer offers a minimally invasive technique with early return to work and minimal complications.”When detected early, surgery offers the best chance of control. But only about 15-20 percent of patients are eligible for surgery at diagnosis. That number reflects how silently the disease advances.Not every episode of acidity hides cancer. Most do not. But persistent, unusual, or worsening symptoms deserve attention. The real challenge is balance. Panic helps no one. But delay can cost time that cannot be recovered.Pancreatic cancer is detected late because it imitates common digestive troubles, responds briefly to simple medicines, and stays hidden deep inside the body. Awareness does not mean fear. It means paying attention.Sometimes, the difference between a routine acidity problem and something more serious lies in how long it lasts, how it changes, and whether it comes with unexplained weight loss or jaundice. That is where timely medical advice becomes critical.Medical experts consulted This article includes expert inputs shared with TOI Health by: Dr Ashwani Kumar Sharma, Vice Chairman – Manipal Comprehensive Cancer Centre & Onco Robotic Surgeries, North-West ClusterInputs were used to explain why pancreatic cancer is often mistaken for common conditions like acidity or gallstones, leading to delayed diagnosis.
