Concepts of territory and organization in normal tissue and their relation to neoplasia,of malignant cell behaviour. During embryonic development, a single cell, the fertilized egg, gives rise to the complex, appropriately organized arrays of differentiated cells that form the tissues of the body. Furthermore, in the embryo, the development of specific tissues involves invasion. For in

The role of the host in facilitating and controlling the development and spread of cancer, Apart from such hormonal effects the major emphasis on the role of the host in the development of cancer has in the past been on the elimination of cancer cells. Facilitation of the growth of cancer by host processes must not, however, be forgotten.

Concepts of carcinogenesis,published ten years ago. His principal theme was ‘the general concept of neoplasia as a sequential developmental process’. This led to the definition of three groups of lesions. Group A (non-neoplastic) is exemplified by ‘freckles and other familiar consequences of over-exposure of skin to sunlight’

Genetic mechanisms in carcinogenesis,material of a cell are part of a multistep pathway leading to malignancy. That genetics plays some role in cancer development has been known for a long time from observations of certain families in which malignancies are clearly inherited.. In addition, the observation that both inherited and non-in

Concepts of territory and organization in normal tissue and their relation to neoplasia,ay also spread to establish secondary growths in the process of metastasis. For example, breast carcinomas can give rise to secondary tumours in distant tissues, including brain and bone. In establishing this typical pattern of metastasis, the malignant cells leave the confines of the epithelium in

The International Union against Cancer (UICC) recognises over 200 distinct neoplastic diseases.; individuals vary enormously in their susceptibility to different types of cancer, in the rate of progression of their diseases, and in
