Cancer remains one of the most significant health challenges of later life. Globally in 2022, approximately 20 million new cancer cases were recorded and about 9.7 million deaths, underscoring the growing burden of disease. Globally, 64 percent of the 19.3 million new cancer cases reported in 2020 occurred in people aged 60 years and older, accounting for 71.3 percent of all cancer-related deaths.
In India, the situation is equally urgent, with the incidence of cancer among older adults (aged 60 +) projected to rise by 13.5 per cent by 2025 compared to 2020. These facts highlight that age is the single most important risk factor for cancer development.
This article explains what cancer means, the common warning signs older adults and their families should recognize, how risk builds up, and the steps individuals and families can take to reduce the risk of cancer and detect it earlier.
What Is Cancer
Cancer starts when some cells in the body stop behaving the way they should. Usually, cells grow, divide, repair damage, and die on a fixed schedule. But when their internal controls fail, these cells begin to multiply without order or limit.
Over time, this uncontrolled growth can create a lump, disturb how an organ functions, or spread to other parts of the body through the blood or lymphatic system.
Because these changes often happen slowly and silently, many people notice symptoms only when the disease has already progressed, which is why paying attention to early signs is important.
Cancer is not one single illness; rather, it is a group of diseases that can start in almost any part of the body. Among older adults in India, the most common types include lung, breast, colorectal, prostate, and oral cancers, the last of which is especially linked to tobacco chewing and betel-nut use.
Although each cancer behaves differently, they all begin with the same underlying problem: cells that grow in a way the body can no longer control.
Why Cancer Risk Increases with Age
Cancer becomes more common with age because the body carries the weight of everything it has lived through.
Decades of exposure to tobacco in any form, polluted air, poor diet, infections, or workplace hazards gradually leave small marks on cells. One or two of these marks may not seem significant, but over a lifetime, they accumulate and increase the likelihood of harmful changes.
As the years pass, the body’s natural repair systems also slow down. The mechanisms that once removed abnormal cells or kept inflammation under control become less efficient. This makes it easier for damaged cells to slip through unnoticed and grow in ways they should not.
Most older adults also live with conditions such as diabetes, obesity, high blood pressure, or chronic lung disease. These illnesses create additional stress inside the body, reducing resilience and making it harder to respond to early cancer changes.
For many seniors in India, the story is shaped by the environments they spent their lives in. Cooking for decades on chulhas with biomass fuels, working in unregulated factories, living around high pollution, or having limited access to screening and preventive healthcare, all these experiences quietly increase cancer risk over time.
Age itself is not the cause. It is the accumulation of a lifetime of exposures, stresses, and slowed repair. Understanding this helps families support older adults with empathy rather than fear.
Cancer Symptoms That Older Adults Should Not Ignore
Some warning signs to watch for include:
- Unexplained weight loss or loss of appetite
- Persistent fatigue or lack of energy despite rest
- A new lump or swelling in any body part
- Changes in bowel or bladder habits (for example, persistent constipation or blood in urine)
- A persistent cough or hoarseness that does not resolve
- Unusual bleeding or bruising without clear cause
- Skin changes: new growths, sores that don’t heal, changes in existing moles
- Difficulty swallowing or a persistent indigestion
- Unusual pain, discomfort or persistent infection in one area
- Loss of interest in usual activities, prolonged low mood combined with physical symptoms
Symptoms Common in Older Adults for Specific Cancer Types
Certain cancer types appear more frequently in older adults and often present with specific patterns that families should understand:
- Lung Cancer: Persistent cough, new or worsening breathlessness, chest pain, hoarseness, or repeated chest infections.
- Colorectal Cancer: Blood in stool, persistent changes in bowel habits, unexplained weight loss, and anemia.
- Prostate Cancer: Difficulty urinating, blood in urine or semen, pain in the hips or back in advanced cases.
- Breast Cancer: New breast lumps, nipple discharge, changes in breast shape or skin texture.
- Oral Cavity Cancer (especially in India): Non-healing sores in the mouth, white or red patches, persistent mouth pain, difficulty chewing or swallowing, and a history of tobacco or betel-nut use.
Key Factors That Increase Risk
Cancer risk builds from a combination of lifelong influences. Some are related to age and biology, while others can change with lifestyle and environment.
Factors related to age and biology
- Changes in DNA repair as the body grows older
- Weakened immune response with age
- Family history of specific cancers
- Inherited genetic conditions that increase risk
- Previous radiation or chemotherapy exposure for past illnesses
Factors related to environment and lifestyle
- Tobacco use in any form, including smoking and chewing
- Long-term alcohol use
- Diets low in fruits, vegetables, and fiber
- High intake of red or processed meats
- Limited physical activity and long periods of sedentary behavior
- Obesity or weight gain over the years
- Chronic infections such as HPV, hepatitis B, or H. pylori
- Indoor smoke from biomass cooking fuels
- Exposure to pollution, industrial fumes, or hazardous materials
- No screening for cancers like breast, colorectal, or cervical cancer
How Cancer Is Diagnosed
Diagnosis begins with listening to the symptoms, the timeline, the changes families have noticed, and the concerns the older adult may not express easily.
A doctor will usually start by understanding when the symptoms began, how they progressed, and whether there are any long-term exposures or family history that may increase risk.
From there, evaluation may include:
- Physical examination, focusing on the areas related to symptoms
- Blood tests to look for anemia, infection markers, or organ changes
- Ultrasound, X-ray, or CT scans to identify any abnormal growths
- Endoscopy or colonoscopy, if symptoms involve the digestive system
- Mammography or breast ultrasound for breast changes
- Biopsy is when a lump or suspicious area needs confirmation
Prevention And Protective Habits That Lower Cancer Risk
Reducing cancer risk in later life comes from caring for the body in simple, steady ways. These habits support healthier cells, calmer inflammation and better overall resilience.
Avoid Tobacco in All Forms
Tobacco is one of the strongest known causes of cancer in India. Cigarettes, bidis, gutka, khaini, and betel quid with tobacco all damage cells in the mouth, throat, lungs, and several internal organs. Stopping use at any age helps reduce the harm that continues to build inside the body.
Regular Physical Activity
Movement helps regulate weight, blood sugar, hormones, and digestion. A simple routine, such as a morning or evening walk, gentle stretching, or basic strengthening exercises, supports better long-term health. Regular physical activity also reduces inflammation, which plays a role in the development of several cancers.
Balanced Eating for Cell Protection
A diet rich in vegetables, fruits, whole grains, dals, nuts and seeds provides antioxidants and fiber that protect cells. Limiting very salty foods, processed meats, deep-fried items, and sugary drinks reduces unnecessary stress on the body. These adjustments help maintain a healthier weight, which is important because obesity is linked to multiple cancers.
Manage Chronic Conditions
Long-standing illnesses such as diabetes, hypertension, thyroid disorders, obesity, and chronic lung disease can weaken the body’s natural defenses. Regular check-ups, taking medicines as prescribed, and following dietary and lifestyle advice help reduce internal inflammation and improve overall resilience.
Awareness of Screening and Early Detection
Screening tests for breast, colorectal, cervical, and prostate cancers help identify changes long before symptoms appear. Early detection allows for simpler and more effective treatment. Many older adults avoid screening due to fear or confusion, which is why calm family support and clear information make a real difference.
Emotional Stability and Social Support
Stress, loneliness, and reduced emotional engagement weaken overall resilience. Maintaining social connections, participating in daily routines, and seeking emotional support when needed indirectly strengthen the body’s natural defenses.
Infection Prevention Where Relevant
Some cancers are linked to long-standing infections. Vaccines such as hepatitis B and HPV reduce the risk of liver and cervical cancers. Discussing vaccination with a doctor helps determine what is suitable for the individual.
Points To Remember
- Cancer becomes more common with age because of long-term changes in cells and immunity.
- Early symptoms may look mild or resemble normal ageing. Paying attention makes a difference.
- Unexplained weight loss, persistent fatigue, lumps, skin changes, prolonged cough, and unusual bleeding are important warning signs.
- Long-term tobacco use, alcohol, poor diet, pollution, and infections significantly raise the risk.
- Screening helps detect several cancers early, especially breast, colorectal, and cervical cancers.
- Balanced meals, regular movement, and good management of chronic illnesses support better health.
- Families play a key role in recognizing changes and guiding timely medical care.

Frequently Asked Questions (FAQs)
The main categories include:
Carcinomas (begin in organs or glands such as the breast, lung, colon, prostate).
Sarcomas (begin in bone, muscle, fat, or connective tissue).
Leukemias (cancers of blood-forming tissues).
Lymphomas (cancers of the immune system’s lymphatic tissues).
Although symptoms vary by type, the following signs deserve attention when they persist: unexplained weight loss, fatigue, new lumps, skin changes, non-healing sores, unusual bleeding, persistent cough, changes in bowel or bladder habits, difficulty swallowing, hoarseness, repeated infections, night sweats, unexplained pain, bloating, appetite loss, persistent indigestion, frequent fevers, breathlessness, change in stool appearance, and swelling in limbs.
Cancer begins when a cell develops damage in its DNA that affects how it grows and divides. Over time, these damaged cells multiply instead of repairing themselves or dying, eventually forming a tumor or spreading to other parts of the body.
Around 90 percent of cancers are linked to factors outside of inherited genetics. These include tobacco use, poor diet, obesity, alcohol, infections, environmental exposures, pollution, radiation, and long-term lifestyle patterns.
No, but unexplained weight loss that continues for weeks should be assessed.
Family history increases risk for certain cancers, but lifestyle and environment also play a major role.
Not always. Growth rate varies by cancer type, overall health and genetic factors.
Yes. Screening tests such as mammography, stool tests for colorectal cancer, low-dose CT for high-risk smokers, and oral cancer checks are generally safe. The doctor will consider age, existing health conditions, and comfort before recommending tests.
Yes. Many cancers do not appear in standard blood work. Blood tests help show changes in organs or detect specific markers, but imaging or biopsies are often needed for confirmation when symptoms persist.
Gentle reassurance works better than pressure. Many older adults hesitate because they fear discomfort, results or the idea of being unwell. What helps most is calm, steady support:
Start with a simple conversation about why the test was advised and how early detection can make care easier.
Offer to accompany them, handle the logistics or speak to the doctor on their behalf if they feel overwhelmed.
Normalize the experience, explaining that screening is a routine health step, not an indication that something is already wrong.
Provide small, practical comforts, such as arranging transport, planning a relaxed day or giving them time to ask questions.
Acknowledge their fear without dismissing it, because being heard often reduces anxiety.
