'leukemia-free' originates from the word 'leukemia,' which comes from Greek 'leukos' meaning 'white' and 'haima' meaning 'blood,' combined with 'free' indicating absence.

'Leukemia' was first used in the 19th century to describe a condition involving an excess of white blood cells. The term 'leukemia-free' emerged as medical treatments advanced, allowing patients to be declared free of the disease.

Initially, 'leukemia' referred to a medical condition involving white blood cells. The term 'leukemia-free' evolved to describe a state of being free from this condition.
