Penning trap mass measurements of neutron-deficient Cd isotopes 99-109Cd have been performed with the ISOLTRAP mass spectrometer at ISOLDE/CERN, all with relative mass uncertainties below 3 · 10-8. A new mass evaluation has been performed. The mass of 99Cd has been determined for the first time, which extends the region of accurately known mass values toward the doubly magic nucleus 100Sn. 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 100In Sp(100In) by a factor of 2.5.
