Penning trap mass measurements of neutron-deficient Cd isotopes {sup 99-109}Cd have been performed with the ISOLTRAP mass spectrometer at ISOLDE/CERN, all with relative mass uncertainties below 3{center_dot}10{sup -8}. A new mass evaluation has been performed. The mass of {sup 99}Cd has been determined for the first time, which extends the region of accurately known mass values toward the doubly magic nucleus {sup 100}Sn. The implication of the results on the reaction path of the rp process in stellar x-ray bursts is discussed. In particular, the uncertainty of the abundance and the overproduction created by the rp-process for the mass A=99 are demonstrated by reducing the uncertainty of the proton-separation energy of {sup 100}InS{sub p}({sup 100}In) by a factor of 2.5.
