Evaluation of Phyllanthus, for Its Anti-Cancer Properties

1.1 Cancer Cancer is a name given to a group of diseases that arise from a single cell when it starts to grow abnormally in an uncontrollable manner to form a group of undifferentiated cells, known as tumour. Tumour can be classified into two categories; benign and malignant. Not all benign tumours are cancerous but all malignant tumours are (Hanahan & Weinberg, 2000). The main difference between these tumours is benign tumour lack the metastatic ability, grows locally and is less harmful. However, some benign tumours can transform into malignant tumours that possess the metastatic ability to invade and spread to other parts of the body via the blood or lymphatic circulation and form secondary tumour and eventually lead to death (Vincent & Gatenby, 2008).
