• an apparatus for simultaneously accessing two or more ductal networks in a breast, said apparatus comprising:
• a manifold having an inlet for receiving fluid and at least two outlets;
• at least two individual ductal access probes, each ductal access probe having a lumen connected to a respective one of said at least two outlets and configured for insertion through an orifice of a ductal network;
• and a collection tube connected to at least one probe for receiving biological material from within the breast;
• and
• instructions including steps for using said apparatus, said instructions comprising the steps of:
• a) introducing a respective one of said ductal access probes into each of at least two of the ductal networks in the breast through a ductal orifice of each of said respective ductal networks;
• b) delivering a substance to at least two of the ductal networks;
• and
• c) collecting a ductal fluid sample from the at least two ductal networks using a plurality of said ductal access probes.
