The review considers the testing of some exotic hypotheses about the properties of the nucleon in a nuclear medium in phenomena of traditional nuclear physics. The hypothesis of nucleon swelling proposed to explain the EMC effects is considered in detail. The consequences of this hypothesis for the charge densities and cross sections for scattering of fast electrons and protons by nuclei are analyzed. Also considered are the Nolen--Schiffer anomaly, the Coulomb sum rule for inelastic electron scattering, {ital y} scaling, and some other nuclear processes. It is shown that one can estimate the possible scale of nuclear exotics by analyzing many of these phenomena. Thus, examination of high-precision data on the elastic scattering of electrons with energy 500--700 MeV using density distributions calculated on the basis of the self-consistent theory of finite Fermi systems yields a restriction on the amount of nucleon swelling: {alpha}={delta}{ital r}{sub {ital N}}/{ital r}{sub {ital N}}{approx lt}10%. A similar analysis for protons with energy 0.8--1.0 GeV using Glauber theory gives {alpha}{approx lt}6%. An even more stringent restriction, {alpha}{approx lt}3%, follows from data on {ital y} scaling in {sup 56}Fe.
