Cancer, uncontrolled cells' growth, is the leading cause of death worldwide. 1 It was estimated that cancer causes more deaths than all coronary diseases or all strokes. 2 Almost 8.2 million people die as a result of cancer each year, accounting for about 13% of all deaths.

This disparity is attributed partly, to early detection and access to advanced diagnostic modalities and cancer therapies. 5 Nigeria has the highest cancer deaths in Africa with 10,000 people dying every year. 1 Although many observers believed that there could be as high as 500,000 new cancer cases annually in Nigeria, the World Health Organisation report that 100,000 new cases are being reported annually. 6 It is projected that by
