A method of milk extraction system may include massaging a posterior of a breast. Massaging and collecting milk may optionally be performed simultaneously. A posterior massager may also be used and/or mounted separately from a collection unit. In some embodiments the massager may be used to improve milk collection and/or alleviate breast ailments for example engorgement, plugged ducts, and/or mastitis. A collection flange may include an air inlet manifold, to mix air and milk. Optionally as air is drawn along a tube by a vacuum, milk may be entrained in the airstream and brought towards a collection vessel. The system may include automated tracking of milk production and/or consumption.
