invasiveness1937

1937 R. W. Fairbrother Text-bk. Med. Bacteriol. vii. 69 The term invasiveness is sometimes erroneously used as synonymous with virulence; it, however, applies strictly to the power of the organism to invade the tissues of the host.

1949 Cancer Res. 9 559/1 Evidence was found indicating that the invasiveness of the cancer cells depended on their lessened adhesiveness.

1967 R. A. Willis Pathol. Tumours (ed. 4) ix. 149 The factors determining invasiveness are still uncertain. Continued excessive proliferation is one of them.

1970 R. Passmore & J. S. Robson Compan. Med. Stud. II. xviii. 28/1 Virulence may involve invasiveness or toxigenicity; some pathogenic organisms are typically invasive, e.g. the causative organisms of typhoid fever.
