Cancer is a complex disease, caused by a combination of genetic, environmental and behavioral factors. However, one of the most obvious and documented aspects is the link between age and increased cancer risk. The older one gets, the greater the likelihood of developing cancer. This relationship has been observed in numerous epidemiological studies and is one of the keys to understanding how to prevent, diagnose, and manage cancer in the elderly population.
Why does age increase the risk of cancer?
- Accumulation of genetic mutations
Over the course of a lifetime, the cells in our bodies divide millions of times. Each division is an occasion when errors in DNA duplication can occur. Most of these errors are corrected automatically, but over time some mutations can accumulate. When these affect genes involved in controlling cell growth and division, the risk of tumor transformation increases.
- Decline in cellular and immune functions
With age, the body gradually loses efficiency in DNA repair mechanisms and in the recognition of abnormal cells. The immune system-responsible for anti-cancer surveillance-also weakens, making it more difficult to eliminate potentially cancerous cells.
- Chronic Inflammation and Oxidative Stress
Aging is often accompanied by a state of chronic low-grade inflammation, which can promote cancer development. In addition, age-related oxidative stress damages genetic material and cellular structures, contributing to genomic instability.
- Prolonged exposure to carcinogens
Over a lifetime, exposure to carcinogens such as cigarette smoke, environmental pollutants, UV rays, alcohol and processed foods accumulates. The effect of these agents is not immediate, but can manifest itself after decades with the appearance of cancer.

What can be done to reduce the risk?
Age, in itself, is not modifiable, but other factors can be acted upon to lower cancer risk:
- Healthy lifestyle: eat a balanced diet, exercise regularly, maintain an adequate body weight and sleep well.
- Primary prevention: avoid tobacco use, reduce alcohol consumption, protect yourself from the sun and limit exposure to toxic substances.
- Regular check-ups: adhere to screening programs (mammography, colorectal, Pap test, etc.) and have periodic check-ups (such as our urinary cytology exam).
- Chronic disease management: conditions such as diabetes, obesity or hypertension can affect cancer risk and should be monitored.

Bladder carcinoma
Older age-related cancers include bladder cancer, which predominantly affects men over the age of 60. This tumor is often underestimated, but it represents one of the most common urologic malignancies.
Primary prevention-quitting smoking, hydrating properly, avoiding exposure to chemicals at work-is therefore essential even at younger ages. After age 50-60, it is important to pay attention to signs such as blood in the urine (hematuria), even in the absence of pain, and report them promptly to the doctor. Although there is no mass screening for bladder cancer, early diagnosis allows more effective and less invasive treatments.
