Cancer (General Information)
What is cancer?
Cancer is a disease that results from abnormal growth and division of cells that make up the body's tissues and organs. Under normal circumstances, cells reproduce in an orderly fashion to replace old cells, maintain tissue health and repair injuries.
However, when growth control is lost and cells divide too much and too fast, a cellular mass, or "tumour," is formed.
Tumours are divided into benign and malignant tumours. A metastasis is where a malignant tumour (cancer) spreads to other organs either by the lymphatics or blood vessels. A benign tumour does not metastasise but may be locally aggressive.
Cancer screening is the performance of tests on apparently well people in order to detect a medical condition at an earlier stage.
