Could syphilis be cured after having it for four years? - secondary syphilis more condition_symptoms

Umm i dnt have, but I know someone who thinks they may have atleast four years. If this is the PDB damage already done. But it is perfectly healthy. I know that the treatment is a dose of penicillin [after which] in the phase. And they have a rash, back, chest and abdomen. I think the secondary or latent phase. Help please!
