The colony‐inhibition test has been used to demonstrate cellular immunity against spontaneous murine mammary tumors, both in autochthonous, mammary tumor virus (MTV)‐carrying BALB/cfC3H and in immunized, MTV‐free, BALB/c mice. Immunity could be demonstrated in nearly all cases against a mammary tumor with lymph‐node cells from mice which had experienced that tumor. One of eight tumors tested with lymph‐node cells from BALB/cfC3H mice which had spontaneously developed mammary tumors showed evidence of immunological cross‐reactivity, while seven of thirteen tumors did so when tested with immune cells from MTV‐free BALB/c mice. The data, therefore, indicate the presence of at least two types of tumor‐specific antigen (s) in mouse mammary tumors — a common one and an antigen specific for each neoplasm.
