rom the cancer. In Johns Hopkins' Hospital forty-seven per cent
of all patients with cancers of the breast operated upon remained well for
three years or more, and seventy-five per cent of this forty-seven per
cent were cured, being in the most favorable condition for cure at the
time of the operation. But where conditions are not favorable at the time
of the operation, many patients have a return of the cancer even after the
three years of apparent cure have elapsed.

What is Cancer?--A cancer is a growth of cancerous cells in a network of
connective tissue. The cause of cancer is not known. It has not been
proved to be communicable and the majority of investigators of this
subject believe that it is not caused by a germ. Nor is it thought to be
inherited. Out of 8,000 cases of cancer at Middlesex Hospital, London, no
evidence of heredity was found. Until the cause of cancer is known, it
cannot be prevented. The only safeguard lies in an early diagnosis of the
condition and an immediate operation. Eminent investigators are carrying
on extensive research and thousands of dollars are being spent annually to
ascertain, if possible, what is the cause of this dread disease, and it is
confidently believed that final success will crown this labor.

When to Suspect Cancer and What to Do.--External or Exposed
Cancer.--Cancer of the exposed or surface parts of the body, such as the
skin of the lip, nose, cheek, forehead, temples, etc., is more readily
recognized than internal cancer, and is therefore more liable to early
operation and prompt cure. One rarely sees these forms of cancer in an
advanced stage, because such cases are readily seen and recognized by
physicians in the early stage of development, when operation can be
sufficiently early to effect a lasting cure.

The least malignant of all cancers is that kind which first exhibits
itself by a hardening of the skin, forming a nodule looking pimple or a
mole and having a dark red color, due to tortuous blood vessels, upon the
sides of the nose near the eyes, upon the cheek bones, forehead or
temples. This form of epithelioma is called rodent ulcer, flat epithelioma
or cancroid and sometimes does little harm for many years, but should
receive the attention of a physician familiar with cancer and its
eradication.

Deep or squamous cancer occurs on the lip, the tongue or the forehead or
wherever the mucous membrane joins the skin, and is characterized by a
hard, deep-seate
