In Fig. 4e,f of this Article, the plotted tumour volumes are incorrect due to an error in the formula used to convert length and width measurements into volume. The formula used was ((length*width)^2)*(22/7)*(1/6), and this should have read (length*(width^2))*(22/7)*(1/6). The resulting smaller tumour volumes do not change the original conclusions. The correct version of Fig. 4 appears below.
