Question

What is leukaemia?

Options

• Cancer arising from glandular tissues

• Cancer arising from epithelial tissues

• Cancer of blood-forming tissues, often involving abnormal white blood cells

• Cancer involving the lymphatic tissues

Answer 1

Leukaemia is a major cancer type affecting blood-forming tissues, characterised by the abnormal proliferation of white blood cells. Unlike solid tumours, leukaemia involves the blood system itself, leading to overproduction of immature or abnormal blood cells that impair normal immune function.
