Mycobacteria are the unique group of bacteria that are currently used in antitumoral immunotherapy. Speciically, intravesical instillation of viable cells of Mycobacterium bovis Bacillus Calmete-Guérin (BCG), after transurethral resection of non-muscle invasive bladder cancer, is the most eicacious treatment for avoiding recurrence and progression of the disease. BCG has been used for the last 35 years for bladder cancer treatment, but other mycobacteria or mycobacteria components are currently

Those are, for instance, cell wall extracts or heat-killed forms from BCG or other mycobacteria such as Mycobacterium phlei or Mycobacterium indicus pranii (MIP) or even viable cells from non-pathogenic mycobacteria such us Mycobacterium brumae. A review of the literature in which mycobacteria components, non-viable mycobacteria, and viable mycobacteria have been used for these diferent cancers will be performed. In this chapter, the function of mycobacteria as antitumor agents will be then analyzed, awarding the audience a broad knowledge of one of the beneicial applications of mycobacteria, which are usually introduced as dangerous microorganisms.
