FAQ

Frequently Asked Questions

Not exactly. While both involve white blood cells, 'leucosis' is a broader pathological term and in modern usage is most specific to veterinary diseases, particularly in birds. 'Leukaemia' is the standard term for specific cancers of the blood-forming tissues in humans.

In British English, it is pronounced /ljuːˈkəʊsɪs/ (lyoo-KOH-sis). The 'c' is soft, like an 's'.

The term is historically connected to diseases like leukaemia, but in current professional English, it is not the standard term for human conditions. You would use 'leukaemia' or specific diagnostic names instead.

The UK spelling is typically 'leucosis' (with a 'c'), while the US spelling is 'leukosis' (with a 'k'), following the pattern of leukaemia/leukemia.

A pathological increase in the number of white blood cells.

Leucosis is usually technical/medical/veterinary in register.

Learning

Memory Aids

Mnemonic
