The presenting features of 526 patients referred to an open access 'lumps and bumps' clinic were reviewed to try and identify whether the four cardinal features of soft tissue malignancy were in fact predictive of this. The features investigated were: size bigger than 5 cm, pain, increase in size, depth beneath the deep fascia. All of these factors were found to be associated more frequently with malignancy than a benign state. Using the summed weights of evidence method we have constructed a graph which will allow prediction of whether a lump is likely to be malignant or not.
