  We extend the study of the recently discovered Yangian symmetry of massive
Feynman integrals and its relation to massive momentum space conformal
symmetry. After proving the symmetry statements in detail at one and two loop
orders, we employ the conformal and Yangian constraints to bootstrap various
one-loop examples of massive Feynman integrals. In particular, we explore the
interplay between Yangian symmetry and hypergeometric expressions of the
considered integrals. Based on these examples we conjecture single series
representations for all dual conformal one-loop integrals in D spacetime
dimensions with generic massive propagators.
