1. A surgical stapling instrument, comprising:
an end effector, comprising:
a first jaw;
a second jaw movable relative to the first jaw to grasp tissue therebetween;
an anvil;
a staple cartridge comprising staples deployable into the tissue, wherein the staples are deformable by the anvil; and
a sensor configured to provide a sensor signal according to a physiological parameter indicative of proximity of the sensor to cancerous tissue; and
a control circuit comprising a processor, wherein the control circuit is coupled to the sensor, and wherein the control circuit is configured to:
receive the sensor signal;
determine a value of the physiological parameter based on the sensor signal;
compare the value of the physiological parameter to a predetermined threshold;
detect a cancerous tissue based on the comparison of the value of the physiological parameter to the predetermined threshold; and
determine, by the processor, a direction to move the end effector based on the cancerous tissue detected by way of the value of the physiological parameter being equal to or outside the predetermined threshold, wherein the direction corresponds to moving the end effector away from the cancerous tissue to a position that is a clear margin away from the cancerous tissue.
