We investigate the utility of the K/sup +/ meson as a probe of effective-size modifications (''swelling'') of nucleons in the nuclear medium. The K/sup +/-nucleus elastic and total cross sections are found to be sensitive to the density-dependent effective masses of the vector mesons (rho,..omega..) whose exchange is responsible for the dominant part of the low-energy K/sup +/-nucleon interaction. This density dependence is estimated in several ways and used to construct a K/sup +/-nucleus optical potential. Such a model is consistent with the K/sup +/+/sup 12/C data at 800 MeVc, and provides a physical picture of the ''swelling'' mechanism in terms of the medium modifications of the meson cloud of the nucleon.
