World Cancer Day 2025: Raising Awareness & Reducing Risk
Observed on February 4th, World Cancer Day is a global initiative led by the Union for International Cancer Control (UICC) to promote awareness, encourage prevention, and improve access to cancer treatment. This day emphasizes the importance of early detection, lifestyle modifications, and medical advancements in reducing the impact of cancer.
While some cancers are more prevalent than others, many can be prevented through healthy habits such as maintaining a balanced diet, exercising regularly, avoiding tobacco, and undergoing routine screenings. Read on to discover the most common types of cancer and how you can lower your risk.
10 Most Common Cancers & Ways to Reduce Risk
1. Breast Cancer
Among the most frequently diagnosed cancers in women, breast cancer risk can be reduced by maintaining a healthy weight, staying physically active, limiting alcohol intake, and undergoing regular screenings like mammograms for early detection.
2. Lung Cancer
Smoking is the primary cause of lung cancer, but exposure to air pollution, secondhand smoke, and radon gas also increases risk. Quitting smoking and minimizing exposure to environmental pollutants can significantly lower the chances of developing the disease.
3. Colorectal Cancer
A diet rich in fiber, reducing consumption of processed meats, and maintaining an active lifestyle can help prevent colorectal cancer. Regular screenings, such as colonoscopies, are essential for detecting precancerous polyps early.
4. Prostate Cancer
Primarily affecting older men, prostate cancer risk can be reduced through a balanced diet rich in fruits, vegetables, and omega-3 fatty acids. Regular checkups and early detection through PSA (Prostate-Specific Antigen) tests play a crucial role in managing the disease.
5. Stomach Cancer
Infection with H. pylori bacteria, excessive salt intake, and consumption of smoked foods increase the risk of stomach cancer. A diet rich in fruits, vegetables, and whole grains can help reduce the likelihood of developing this cancer.
6. Liver Cancer
Hepatitis B and C infections, heavy alcohol consumption, and obesity are major risk factors for liver cancer. Vaccination against hepatitis and limiting alcohol intake are key preventive measures.
7. Cervical Cancer
Cervical cancer is primarily caused by the human papillomavirus (HPV). The risk can be lowered through HPV vaccination, regular Pap smears, and practicing safe sex.
8. Oesophageal Cancer
Risk factors for oesophageal cancer include acid reflux (GERD), smoking, and excessive alcohol use. Maintaining a healthy weight, avoiding tobacco and alcohol, and treating acid reflux can significantly reduce the risk.
9. Skin Cancer
Excessive UV exposure is the leading cause of skin cancer, particularly melanoma. Using sunscreen, avoiding tanning beds, and performing regular skin checks are key preventive strategies.
10. Pancreatic Cancer
Smoking, obesity, and chronic pancreatitis are known risk factors for pancreatic cancer. A diet rich in fruits, vegetables, and whole grains, combined with avoiding smoking and heavy alcohol use, can help lower the risk.
While genetics may play a role in some cancers, making lifestyle changes such as eating a balanced diet, staying active, avoiding smoking and alcohol, undergoing regular screenings, and getting vaccinated can significantly reduce the risk of many types of cancer.
