Impact of Primary Care Delay on Progression of Breast Cancer in a Black African Population: A Multicentered Survey
Table 2
Distribution of interval lengths and risk of tumor size migration: The mean and median of the primary care interval were longer than the patient interval. Risk of stage migration increased as the patient stayed longer in the primary care interval.
