Cancer remains one of the deadliest diseases across Africa, accounting for a significant number of fatalities annually.
According to the World Health Organization (WHO), the continent records approximately 1.1 million new cancer cases each year, with nearly 700,000 deaths.
The theme for World Cancer Day 2025-2027, “United by Unique,” introduced by the Union for International Cancer Control (UICC), emphasizes a patient-centered approach and innovative solutions to enhance cancer care. Hematologist and Oncologist Dr. Jeff Vacirca, an alumnus of St. George’s University (SGU) School of Medicine in Grenada, West Indies, highlights the importance of understanding cancer risks, early detection, and proactive prevention.
Understanding Cancer Risks
The WHO reports that cancer is among the leading causes of mortality worldwide, contributing to roughly 9.7 million deaths annually. While some risk factors are unavoidable, many can be managed through lifestyle changes. Key contributors to cancer risk include:
- Lifestyle Choices: Tobacco use, excessive alcohol consumption, unhealthy diets, and lack of physical activity.
- Environmental Factors: Exposure to air pollution, ultraviolet radiation, and harmful carcinogens.
- Biological and Genetic Influences: Age, hereditary predisposition, and weakened immune systems.
By recognizing these risks, individuals can take preventive measures to lower their chances of developing cancer.
The Power of Regular Screenings
Early detection significantly improves survival rates by enabling timely intervention. Routine screenings such as mammograms, pap smears, and colonoscopies can identify abnormalities before they develop into severe conditions. For example, detecting breast cancer in its earliest stages can lead to a five-year survival rate of up to 99%, compared to just 27% for cases diagnosed at an advanced stage. Prioritizing routine screenings increases the chances of successful treatment and long-term recovery.
Recognizing Symptoms Early
Cancer symptoms can vary based on the type and stage of the disease, but being vigilant about the following warning signs can lead to early diagnosis and treatment:
- Physical Indicators: Persistent lumps, swelling, chronic cough, breathlessness, changes in bowel habits, unexplained weight loss, fatigue, and unusual bleeding.
- Urinary System Changes: Frequent urination, difficulty urinating, and pain while urinating.
- Other Symptoms: Loss of appetite, unusual breast changes, long-lasting soreness, heartburn, and excessive night sweats.
Seeking medical attention when experiencing these symptoms can facilitate early intervention and improve treatment outcomes.
Preventing Cancer Through Lifestyle Choices
Adopting a proactive approach to health can significantly reduce cancer risks. Dr. Vacirca emphasizes the following preventive measures:
- Healthy Living: Avoid tobacco products, maintain a balanced diet, engage in regular physical activity, and moderate alcohol intake.
- Vaccination: Get vaccinated against HPV and hepatitis B to reduce the risk of virus-related cancers.
- Environmental Awareness: Minimize exposure to ultraviolet radiation, practice sun protection, and reduce contact with indoor and outdoor pollutants.
The Call for Collective Action
As CEO and Chairman of New York Cancer & Blood Specialists and co-founder of OneOncology, Dr. Vacirca stresses the need for collective efforts in cancer prevention. “World Cancer Day serves as a reminder of the devastating effects of cancer in Africa and beyond. By promoting healthier lifestyles, advancing vaccination efforts, and encouraging early detection, we can work together to reduce the burden of this disease and create a healthier future for all.”
Raising public awareness and educating communities on early detection are critical steps toward combating cancer. St. George’s University urges individuals and organizations across Africa to champion cancer education, advocate for regular screenings, and support those affected by the disease. Through unified action, a future with lower cancer-related fatalities is within reach.
