Venn diagram depicting the four largest symptom groups in 2316 breast cancer patients. The three shaded groups in red were not investigated due to small numbers: breast lump and non-breast symptoms (n = 12), non-lump breast symptoms and non-breast symptoms (n = 7), and breast lump, non-lump breast symptoms, and non-breast symptoms (n = 1). The full symptom taxonomy is presented in Fig. A.2. in the Supplementary material (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
