Materials and Methods: Female patients who met the following inclusion criteria were included in this study: First, diagnosis of any type of cancer at grade 1 only, second, a measurement of RBC and Hb, RBC count less than 4.5 M μL1 and haemoglobin Hb level less than 11.5 g μL1. Results: Among this study, breast cancer was the common type, followed by female genital tract, colorectal and the least common type is head and neck. Significantly, the highest number of anaemia cases detected were in the colorectal cancer group (32%), followed by the breast group with 29%), the female genital tract (27%) and the head and neck cancer group with about 12%).
