s, loss of
appetite, pain in the side, loss of weight, getting tired easily,
feeling run down, rise in temperature in the afternoon, night sweats,
expectoration, and spitting blood. No one, nor even several, of these
symptoms necessarily indicates the presence of tuberculosis; on the
other hand, even the cough is not necessarily present when tuberculosis
actually exists. When one or more of these symptoms appears and
continues, a thorough examination should be made by a doctor;
examination can do no harm, certainly, if tuberculosis is not found, and
if it is, immediate treatment is of the greatest importance. No known
drug or medicine is a cure for tuberculosis. Successful treatment
depends on taking the disease in time and in following the doctor's
advice unremittingly.

CANCER.--The cause of cancer is not known. All the evidence, however,
goes to show that it is neither communicable nor hereditary. Cancer may
occur on the skin, stomach, or other organs; in women it most commonly
occurs in the breast or uterus (womb). In both sexes it occurs most
frequently after 40 years of age. No known medicine will cure cancer;
salves and ointments have no effect. Radium and _x_-ray should not be
relied upon if the cancer can be removed by operation. Safety consists
in removing the growth entirely, and complete removal is possible only
in the early stages.

Early diagnosis is consequently of the greatest possible importance, and
an examination can do no harm in any case. Warts and moles on the skin
may develop into cancer, and should be removed if they show signs of
irritation. Loss of appetite and weight, any disturbance of the stomach
or intestines, and sores that refuse to heal should lead a person to
consult a physician; the same is true of any lump in the breast, and of
irregular or persistent bleeding from the uterus in women over forty.
The fact that pain is not present in cancer until the late stages leads
many persons to neglect the trouble until it is too far advanced for
operation. Time is all-important; hope depends on operation in the early
stages when there is a very great probability of permanent cure.

MENTAL ILLNESS.--Insanity, like cancer, is increasing. Like both cancer
and tuberculosis, hope lies in prevention and early treatment; and like
them both, in its early symptoms it is too often unrecognized or
neglected.

Many people are surprised to learn that known, avoidable causes are
responsible for the condi
