Metastasis-specific (a) and overall (b) survival curves of breast cancer patients with and without visceral metastasis. Kaplan–Meier plots of patients show that tumours with visceral metastasis had worse survival outcomes than the tumours without visceral organ metastasis. Patients who had visceral metastasis had shorter survival time from detection of metastasis to last event and from the initial diagnosis of the disease to last event (p = 0.009 and 0.073, respectively)
