Abstract
We present a general overview of the structure and evolution of massive stars of masses ≥12 M ⊙ during their presupernova stages We think it is worth reviewing this topic owing to the crucial role of massive stars in astrophysics especially in the evolution of galaxies and the universe We have performed several test computations with the aim to analyze and discuss many physical uncertainties still encountered in massivestar evolution In particular we explore the effects of mass loss convection rotation 12Cαγ16O reaction and initial metallicity We also compare and analyze the similarities and differences among various works and ours Finally we present useful comments on the nucleosynthesis from massive stars concerning the sprocess and the yields for 26Al and 60Fe
