The haemotological parameters namely Mean corpuscular, Mean corpuscular haemoglobin, Mean corpuscular haemoglobin concentration, Haemotocrit, Haemoglobin, Red blood corpuscles, Red cell distribution, Erythrocytes and Monocyte are decreased when compare to control but Platelet, Mean platelet volume, Total white blood corpuscular and Lymphocyte count are decreased among the three groups of cancer patients.
