Correct answer: B – Formation of new, abnormal growth of tissue
Neoplasia is defined as the formation of new, abnormal growth of tissue. The term comes from "neo" (new) and "plasia" (growth or formation).
Correct answer: C – Swelling in inflammation
The term "tumour" originally meant swelling in inflammation before it came to be associated with neoplastic growths. It derives from the Latin word for swelling.
Correct answer: B – Latin word for crab
Cancer comes from the Latin word for crab. It is the common term for all malignant tumours, possibly named because of the crab-like spreading pattern of some cancers.
Correct answer: C – -oma
Benign neoplasms are typically designated with the suffix "-oma" added to the cell of origin, such as fibroma, lipoma, or chondroma.
Correct answer: B – Lipoma
A benign neoplasm of adipose (fat) tissue is called a lipoma. The suffix "-oma" indicates it is benign, and "lipo-" refers to fat.
Correct answer: C – Sarcoma
Malignant neoplasms of mesenchymal origin are usually called sarcomas, such as liposarcoma (malignant fat tumor) or fibrosarcoma (malignant fibrous tumor).
Correct answer: B – Carcinoma
Malignant neoplasms of epithelial origin are called carcinomas, such as squamous cell carcinoma or basal cell carcinoma.
Correct answer: A – Adenoma
A benign neoplasm of glandular epithelial origin is called an adenoma (solid) or cystadenoma (if it forms large cysts).
Correct answer: C – Adenocarcinoma
A malignant neoplasm of glandular epithelial origin is called an adenocarcinoma, indicating both its glandular nature and malignant behavior.
Correct answer: B – Papilloma
A papilloma is a benign neoplasm characterized by finger-like or warty projections, commonly seen on skin or mucosal surfaces.
Correct answer: B – 10 million
In the year 2000, there were 10 million new cancer cases globally, with 6 million cancer deaths that year.
Correct answer: C – 18.1 million
In 2020, there were 18.1 million new cancer cases globally, showing a significant increase from 10 million in 2000.
Correct answer: C – 1 in 6
In 2020, cancer caused 10 million deaths globally, accounting for 1 in 6 deaths worldwide, highlighting its massive public health impact.
Correct answer: C – 37,000
In Kenya in 2012, there were 37,000 new cancer cases and 28,500 deaths from cancer.
Correct answer: C – 3rd leading cause
In Kenya in 2018, cancer was the 3rd leading cause of death, with 47,887 new cases and 32,987 deaths.
Correct answer: B – Oncology
Oncology is the study of tumors, derived from the Greek word "oncos" meaning tumor. It encompasses the study of cancer diagnosis, treatment, and prevention.
Correct answer: B – Fibroma
A benign neoplasm of fibrous connective tissue is called a fibroma. The malignant counterpart would be a fibrosarcoma.
Correct answer: C – Chondroma
A benign neoplasm of cartilage is called a chondroma. The malignant version is called chondrosarcoma.
Correct answer: C – Melanoma
Melanoma is oddly named because despite having the "-oma" suffix typically used for benign tumors, it is actually malignant. Seminoma is another example of unusual nomenclature.
Correct answer: B – Epidemiology
Epidemiology deals with the study of disease distribution, patterns, and determinants in populations, including cancer incidence, prevalence, and risk factors.
Correct answer: A – Aetiology
Aetiology (or etiology) is the study of disease causation, examining factors that cause or contribute to the development of neoplasms.
Correct answer: C – Pathogenesis
Pathogenesis refers to the mechanism or sequence of events by which a disease develops, including the molecular and cellular changes that occur.
Correct answer: B – Liposarcoma
A malignant neoplasm of fat (adipose) tissue is called a liposarcoma. The benign counterpart is a lipoma.
Correct answer: B – Squamous cell carcinoma
Squamous cell carcinoma arises from squamous epithelium and is a malignant neoplasm of epithelial origin, commonly found in skin, lung, and other organs.
Correct answer: B – 10,887
New cancer cases in Kenya increased from 37,000 in 2012 to 47,887 in 2018, an increase of approximately 10,887 cases, representing about a 29% increase.
