Most people treat themselves instead of seeing a doctor
Each year, more than 38,000 Indians die from a cancer that medicine knows how to prevent and catch early — yet the majority of the population cannot name its most visible warning sign. Colorectal cancer has quietly become one of India's most common malignancies, fed not by biological inevitability but by a confluence of lifestyle shifts, cultural reluctance, and a profound gap in health literacy. The disease asks only to be noticed in time, and time, it turns out, is precisely what fear and embarrassment conspire to waste.
- India records 65,000 new colorectal cancer cases and over 38,000 deaths annually, yet 82% of surveyed citizens cannot identify blood in the stool as a warning sign — the disease is hiding in plain sight.
- Younger adults are increasingly among the diagnosed, shattering the assumption that this is an old person's illness and leaving a generation unprepared to recognize their own risk.
- When symptoms do appear, nearly half of Indians reach for self-medication rather than a doctor, with fear, embarrassment, and time pressure forming a wall between patient and diagnosis.
- Colonoscopy screening — recommended for everyone over 45 — is being avoided en masse due to myths and misinformation, turning a routine procedure into an imagined ordeal.
- Doctors and public health advocates are pushing for awareness campaigns that demystify screening and reframe digestive symptoms as signals worth taking seriously, not managing quietly at home.
India faces a quiet but accelerating crisis in colorectal health. With roughly 65,000 new diagnoses and more than 38,000 deaths each year, the disease now ranks among the country's five most common cancers — yet a nationwide survey of over 10,000 people found that more than four in five Indians did not know that blood in the stool could be an early sign.
The cancer is largely preventable, and when caught early, highly treatable. But the conditions enabling it are spreading: sedentary routines, diets heavy in processed and restaurant food, and a widespread assumption among younger adults that colorectal cancer belongs to old age. More than half of those surveyed did not exercise three times a week, and nearly a third ate packaged or restaurant food almost daily.
When symptoms emerge — changed bowel habits, persistent discomfort, rectal bleeding — the dominant response is avoidance. Nearly 45% of respondents self-medicated for gastric issues, and fewer than 12% consulted a physician. The barriers were named plainly: not enough time, fear of what might be found, and embarrassment about the nature of the symptoms. Over 61% reported experiencing irregular bowel movements, yet most managed the problem privately rather than professionally.
Specialists at Medanta Hospital in Noida stress that the biology of colorectal cancer — polyps forming slowly over years before becoming malignant — makes early screening not just useful but decisive. Current guidelines call for colonoscopy starting at age 45, with earlier and more frequent screening for those with family history. Blood markers and stool tests can also raise early flags. Lifestyle changes remain a meaningful line of defense.
The distance between what is preventable and what is actually prevented is still vast, measured each year in tens of thousands of lives. Closing it will require more than medical guidance — it will require a cultural willingness to take the body's quieter warnings seriously.
Every year, India records roughly 65,000 new cases of colorectal cancer and more than 38,000 deaths from the disease. It is now among the five most common cancers in the country, and globally it ranks third. Yet most Indians do not know the warning signs. A nationwide survey of over 10,000 people found that 82 percent were unaware that blood in the stool could signal the disease's early stages.
The cancer itself is largely preventable and highly treatable when caught early. The problem is not the disease's biology but the gap between what people know and what they need to know. Unhealthy eating patterns, obesity, sedentary living, and poor understanding of gut health have all contributed to rising cases, particularly among younger adults who might assume colorectal cancer is a problem for the elderly. The survey revealed that more than half of respondents did not exercise at least three times weekly, and 30 percent consumed restaurant or packaged food almost daily.
When symptoms appear—blood in stool, changes in bowel habits, persistent digestive discomfort—most people do not go to a doctor. Instead, they treat themselves. The survey found that 44.6 percent of respondents self-medicated for gastric issues, while 43.9 percent turned to home remedies. Only 11.5 percent consulted a physician. The reasons for avoidance were clear: lack of time accounted for 30.6 percent of responses, fear for 27.1 percent, and embarrassment for 23.8 percent. Another 18 percent simply did not think their symptoms warranted professional attention.
When bowel habits changed for weeks, half the respondents reached for over-the-counter medicines. Thirty-five percent attempted to fix the problem through diet and lifestyle changes alone. Fewer than 15 percent saw a doctor. This pattern is particularly troubling given that over 61 percent of those surveyed reported experiencing irregular bowel movements at some point. The reliance on self-management, while sometimes sensible, becomes dangerous when it delays diagnosis of a serious condition.
Dr. Vivek Tandon, Director of Gastrointestinal Surgery and Oncosurgery at Medanta Hospital in Noida, emphasized that understanding how a healthy colon can develop polyps and eventually progress to cancer makes the case for early screening obvious. Yet myths and misconceptions about colonoscopy—the standard screening procedure—keep people away. Dr. Deepak Govil, also at Medanta, noted that many hesitate to undergo the procedure due to lack of awareness or false beliefs about what it entails.
Current guidelines recommend colonoscopy screening for people over 45 years of age, though other tests—blood work, stool analysis—can flag warning signs earlier. Markers related to anemia, carcinoembryonic antigen levels, and the presence of blood in stool can all prompt a doctor to recommend colonoscopy. Those with a family or genetic history of colorectal cancer need more frequent screening. Lifestyle changes—eating well, exercising regularly, avoiding tobacco—significantly reduce risk.
The path forward requires breaking through the barriers that keep people from seeking help. Greater awareness of early warning signs, demystification of screening procedures, and a cultural shift toward treating digestive symptoms seriously could catch more cancers at treatable stages. For now, the gap between what is preventable and what is actually prevented remains wide, measured in thousands of lives each year.

A Conversa do Hearth Outra perspectiva sobre a história
Why does India have such a high rate of colorectal cancer compared to other countries?
It's not that India has the highest rate globally—it's third worldwide. But the combination of rising obesity, dietary changes toward processed foods, and low awareness means cases are climbing, especially in younger people who don't expect to get it.
The survey found that 82 percent didn't know blood in stool was a warning sign. That's staggering. How does that happen?
There's no public health campaign around it. Colorectal cancer isn't discussed the way breast cancer or cervical cancer are. People don't talk about their bowels. The shame and embarrassment are real barriers.
But even when people have symptoms, they don't go to doctors. Why would someone ignore bleeding?
Fear plays a role—what if it's cancer? Embarrassment too. But mostly it's practical: people are busy, they don't have time, they think it will pass. And if it's just occasional, they convince themselves it's not serious.
The survey showed 44.6 percent self-medicate instead of seeing a doctor. Isn't that dangerous?
Absolutely. You might treat the symptom—take an antacid, change your diet—and feel better temporarily. But if there's a polyp or early cancer, you're just masking it while it grows.
What would actually change behavior?
Breaking the myths about colonoscopy is one part. But you also need people to understand that colorectal cancer is preventable. If they knew that screening at 45 could save their life, and that the procedure itself isn't as bad as they imagine, more would do it.
Is there hope in the younger cases being detected?
In a way, yes. If younger people start getting screened and the disease is caught early, survival rates are much higher. But first they have to know they're at risk and that symptoms matter.
