1. A treatment support device comprising:
an irradiation unit configured to irradiate a medical agent with treatment light in treatment for killing cancer cells by irradiating the medical agent with the treatment light of a predetermined wavelength, the medical agent including a fluorescent material administered to a body of a subject;
a fluorescence detector configured to detect fluorescence emitted by the fluorescent material of the medical agent excited by irradiation of the treatment light;
a change calculator configured to acquire a change degree of a fluorescence signal detected by the fluorescence detector in a first time range within a treatment time;
a determination calculator configured to determine whether or not a progress of the treatment is in a steady state, based on at least a fact that the change degree of the fluorescence signal within the first time range acquired by the change calculator has fallen within a predetermined range of the change degree; and
an operation controller configured to control a predetermined operation related to a fact that the treatment is in the steady state when it is determined by the determination calculator that the progress of the treatment is in the steady state.
