Figure 2From: Excessive milk production during breast-feeding prior to breast cancer diagnosis is associated with increased risk for early eventsKaplan-Meier estimate of breast cancer-free survival in relation to milk production. a. Kaplan-Meier estimate of breast cancer-free survival in relation to four categories of milk production (P=0.011). The number of patients at each follow-up is indicated. Since this is an ongoing study, the number of patients decreases with each follow-up. b. Kaplan-Meier estimate of breast cancer-free survival in relation to ‘excessive milk production’ (P=0.001). In this figure ‘excessive milk production’ is compared to the three categories with lower milk production. The number of patients at each follow-up is indicated. Since this is an ongoing study, the number of patients decreases with each follow-up.Back to article page
