The TOTEM (TOTal cross section, Elastic scattering and diffraction dissociation Measurement at the LHC) experiment at LHC, has been designed to measure the total proton-proton cross-section with a luminosity-independent method, based on the optical theorem, and study the elastic and diffractive scattering at the LHC energy. This method relies on the capability of the simultaneous measurements of inelastic and elastic rates; in the TOTEM experiment this is possible thanks to two forward inelastic telescopes, covering the pseudorapitidy range $3.1 < |\eta | < 6.5$, and Roman Pot detectors, that can be inserted down to few hundred microns to the beam centre. In this contribution the status and evolution of the TOTEM experiment will be described along with its latest physics results.
