Leukaemia is a type of cancer affecting blood cells and does not occur in epidemic form.
Epidemics refer to a widespread occurrence of an *infectious disease* in a community at a particular time. Cholera and Plague are historical infectious diseases that have caused major epidemics in India. Swine flu (H1N1) is a viral infectious disease that has also caused outbreaks in India.
While cancer rates can vary regionally or over time, it is not an infectious disease and does not spread from person to person in a way that causes epidemics. The term “epidemic” is specific to infectious diseases.
