Prevalence of Cancer in Nigeria
Cancer prevalence in Nigeria has steadily increased over the years. This trend is attributed to factors such as an aging population, changes in lifestyle, and improved diagnostic capabilities. Breast and cervical cancer in women, and prostate cancer in men, are the most common types of cancer. The rising prevalence highlights the importance of comprehensive cancer control programs in the country..
Cancer in Nigeria Statistics
Cancer statistics in Nigeria reveal concerning trends. For example, breast cancer is the most common cancer in women, while prostate cancer is more common in men. The high mortality rate associated with late-stage diagnosis and limited access to treatment facilities is a major source of concern. Furthermore, the financial burden of cancer treatment places additional strain on individuals and families.
Incidence of Cancer in Nigeria
The number of new cases diagnosed with cancer in Nigeria is referred to as the incidence. As the incidence of cancer rises, so does the demand for oncology services such as screening, diagnosis, and treatment. The healthcare system, on the other hand, faces challenges such as insufficient funding, a lack of specialized facilities, and a shortage of trained personnel. To reduce the incidence and impact of cancer in Nigeria, efforts to improve early detection and access to quality care are critical.
HISTORY OF CANCER
cancer has been a persistent presence. The earliest known record of cancer dates back to around 1600 BC in the Edwin Smith Papyrus of ancient Egypt, specifically mentioning breast cancer. The Greek physician Hippocrates classified various types of cancer using the term "karkinos," which referred to the crab-like appearance of tumors. Galen, another prominent physician, attributed the name "cancer" to the disease's resemblance to a crab due to the protrusions of the tumor and the distended veins surrounding it. The term "karkinos" was later translated into Latin as "cancer" by Celsus, who also recommended surgical intervention for treatment. However, Galen opposed surgery and advocated for the use of purgatives instead, and this approach prevailed for many centuries.
In the 15th, 16th, and 17th centuries, dissection became an acceptable practice among doctors, leading to advancements in understanding the causes of diseases. Wilhelm Fabry, a German professor, proposed that breast cancer resulted from a clot in a mammary duct, while Francois de la Boe Sylvius, a Dutch professor, believed that cancer and other diseases were caused by chemical processes and acidic lymph fluid. Sylvius' contemporary, Nicolaes Tulp, considered cancer to be a contagious poison that spreads gradually.
During the year 1761, Doctor John Hill made the connection between inhaling tobacco and the development of nasal cancer, while in 1775, Surgeon Percivall Pott observed a high occurrence of cancer affecting the scrotum among chimney sweeps. The advent of the microscope in the 18th century allowed for the discovery of the spread of cancer cells, known as metastasis, from the primary tumor to other locations through the lymph nodes. This understanding was initially formulated by English surgeon Campbell De Morgan between 1871 and 1874.
Causes of Cancer in Nigeria
Several factors contribute to cancer development in Nigeria. Smoking, excessive alcohol consumption, and a diet high in processed foods can all increase the risk. Infections such as hepatitis B and C, as well as human papillomavirus (HPV), have also been linked to certain types of cancer. Environmental factors such as chemical exposure and genetic predisposition also play a role.
TYPES OF CANCER:
Cancer manifests in various forms, affecting different organs and systems within the human body. Let's explore some of the most prevalent types of cancer and their characteristics:
- Breast Cancer: Predominantly affecting women but also occurring in men, breast cancer originates in the breast tissue and may spread to nearby lymph nodes and other parts of the body if not detected and treated early.
- Lung Cancer: Primarily caused by smoking but also resulting from exposure to environmental pollutants, lung cancer originates in the lungs and can spread rapidly, emphasizing the importance of early detection.
- Prostate Cancer: Developing in the prostate gland, part of the male reproductive system, prostate cancer is one of the most common types of cancer in men and typically progresses slowly.
- Colorectal Cancer: Affecting the colon or rectum, colorectal cancer often arises from polyps. Regular screenings can help identify and remove polyps before they become cancerous.
- Skin Cancer: Skin cancer occurs when abnormal skin cells proliferate uncontrollably, usually due to excessive exposure to ultraviolet (UV) radiation. Protecting the skin from sun damage and regularly examining moles or skin abnormalities are essential preventive measures.
These examples represent only a fraction of the cancer types that can occur throughout the body. Each type has its own unique characteristics, risk factors, and treatment options. If you experience any unusual symptoms or have concerns, consulting with a healthcare professional for proper evaluation and diagnosis is crucial.
CAUSES AND RISK FACTORS OF CANCER:
Understanding the causes and risk factors associated with cancer is essential for prevention and early detection. While cancer can be influenced by a combination of genetic and environmental factors, some common risk factors include:
1. Genetic Factors: Certain inherited gene mutations, such as BRCA1 and BRCA2 genes associated with breast and ovarian cancer, can increase the risk of developing specific types of cancer.
2. Environmental Exposures: Exposure to carcinogens like tobacco smoke, asbestos, certain chemicals, and radiation can contribute to cancer development.
3. Lifestyle Choices: Unhealthy habits such as smoking, excessive alcohol consumption, a poor diet lacking fruits and vegetables, a sedentary lifestyle, and obesity can increase the risk of various cancers.
4. Age and Family History: Advancing age and a family history of cancer can elevate the likelihood of developing the disease.
5. Infectious Agents: Certain infections caused by viruses, bacteria, or parasites, such as human papillomavirus (HPV), hepatitis B and C, and human immunodeficiency virus (HIV), are linked to an increased risk of specific cancers.
It's important to note that having one or more risk factors does not guarantee the development of cancer. Conversely, individuals without apparent risk factors can still develop cancer. Understanding the risk factors helps in adopting preventive measures and leading a healthier lifestyle.

2. Screenings and Check-ups: Regular screenings and check-ups can detect cancer or pre-cancerous conditions at early stages when treatment is often more effective. Common screening methods include mammograms, Pap smears, colonoscopies, and prostate-specific antigen (PSA) tests.
3. Vaccinations: Vaccines, such as the HPV vaccine, can protect against certain cancer-causing infections.
4. Environmental Awareness: Minimizing exposure to environmental carcinogens, such as wearing protective clothing and using sunscreen to shield the skin from harmful UV rays, is crucial.
5. Self-Examination: Performing regular self-examinations, such as breast self-exams or skin checks, can help identify any changes or abnormalities that require further evaluation by a healthcare professional.
DIAGNOSIS FOR CANCER
1. Imaging tests: These include X-rays, CT scans, MRI scans, ultrasound, and PET scans. These tests help visualize the internal structures and identify any abnormalities or tumors.
2. Biopsy: A biopsy involves the removal of a sample of tissue or cells from the suspected tumor or affected area. The sample is then examined under a microscope to determine if cancer is present and to identify its type.
3. Blood tests: Certain blood tests can help detect specific tumor markers or abnormal levels of certain substances in the blood that may indicate the presence of cancer.
4. Endoscopy: Endoscopic procedures involve using a thin, flexible tube with a camera and light attached (endoscope) to examine the inside of the body, such as the digestive tract or respiratory system, and obtain tissue samples if necessary.
5. Genetic testing: Genetic tests can identify specific gene mutations or genetic alterations that may increase the risk of developing certain types of cancer or help in the diagnosis and treatment planning.
6. Cytology tests: Cytology tests involve examining cells collected from body fluids or secretions, such as Pap smears to detect cervical cancer or sputum samples for lung cancer.
These diagnostic methods help healthcare professionals confirm the presence of cancer, determine its type and stage, and develop an appropriate treatment plan.
