A method of removing material from a patient and placing a marker within the patient, comprising the step of:
- providing a tissue removing device including a tubular element having an opening through which tissue is removed, the tissue removing device also having a solid marker;
- introducing the tissue removing device into a patient;
- placing tissue in the device through the opening;
- cutting the tissue which has entered the device through the opening to separate the a tissue mass from the surrounding tissue;

A method of removing tissue from a patient and marking tissue which remains within the body, comprising the steps of:
- providing a tissue removing device having an opening and a tissue marking element, the tissue marking element including a container having an outlet, the container containing a flowable substance;
- introducing the tissue removing device into a patient so that the opening is adjacent to a tissue area of interest in a patient;
- passing a tissue mass through the opening and into the tissue removing device;
- severing the tissue mass from surrounding tissue so that the tissue mass is at least partially contained in the tissue removing device;
- and
- forcing the flowable substance through the outlet of the tissue marking element, the flowable substance being deposited in tissue thereby marking the tissue.
