We present the results of a three-year Johnson V and Stromgren uvbybeta photometric study about the delta Sct star BR Cnc. The Fourier analysis of the data suggests four pulsation frequencies for this variable: f_1=24.978, f_2=11.358, f_3=11.808 and f_4=27.914/d. Amplitude variations from year to year are found for each of the frequencies. The most relevant physical parameters of BR Cnc are also derived.
