1. A multi-axis tumor marker system comprising:
a) a catheter having a proximal and a distal end with a distal end opening;
b) a marker extension configured to retain a marker and extend from the distal end opening of the catheter for depositing said marker;
wherein the marker is deposited along multiple axes radially about a tumor to define a boundary of margin tissue for excision;
wherein the marker extension comprises an axial marker-extension configured to extend axially from the distal end opening of the catheter to deposit said marker along a catheter axis;
wherein the axial marker-extension is configured to deposit said marker on a distal end of said boundary of said margin tissue to produce a distal marker; and
a plurality of radial marker-extensions, each extending within the catheter and containing a radial marker;
wherein each of the plurality of radial marker-extensions is configured to extend radially out from the distal end opening of the catheter when pushed out from said distal end opening; and
wherein each of the plurality of radial marker-extensions is configured to deposit said radial marker on a radial boundary of said margin tissue; and
wherein a zero degree radial marker-extension of the plurality of radial marker-extensions is configured to extend in a zero degree radial direction from the distal end opening and wherein a 180 degree radial marker-extension of the plurality of radial marker-extensions is configured to extend substantially 180 degrees from the zero degree radial marker-extension; and
a 90 degree radial marker-extension of the plurality of radial marker-extensions that is configured to extend substantially 90 degrees from the zero degree radial marker-extension and further comprising a 270 degree radial marker-extension of the plurality of radial marker-extensions that is configured to extend substantially 270 degrees from the zero degree radial marker-extension.
