During recent years much has been written concerning Malignant disease in early life, and many cases published. Most of these, however, refer to neoplasms of a sarcomatous nature, but the number of recorded cases of carcinoma and epithelioma in the young is comparatively rare. This is to a large extent accounted for by the fact that should a malignant growth occur in a young subject, it is most frequently of the nature of a sarcoma.
In using the term "cancer" in what is to follow I refer to neoplasms of a carcinomatous or epitheliomatous nature only and do not include sarcomas.
Even in standard text books on the subject of diseases of children, and in those dealing specially with the subject of malignant disease little or nothing is to be found concerning cancer in young subjects.
