ubt that something like this does take place.
There is a relation between malformations due to imperfect development
of the embryo and tumors, the two conditions occurring together too
frequently to be regarded as mere coincidence. Also tumors may occur
in parts of the body in which there is no tissue capable of forming
structures which may be present in the tumors. The theory, however, is
not adequate, but it may be among the factors.

The problems concerned in the nature and cause of tumors are the most
important in medicine at the present time. No other form of disease
causes a similar amount of suffering and anxiety, which often extends
over years and makes a terrible drain on the sympathy and resources of
the family. The only efficient treatment for tumors at the present
time is removal by surgical operation, and the success of the
operation is in direct ratio to the age of the tumor, the time which
elapses from its beginning development. It is of the utmost importance
that this should be generally recognized, and the facts relating to
tumors become general knowledge. Tumors form one of the most common
causes of death (after the age of thirty-five one in every ten
individuals dies of tumor); medical and surgical resources are, in
many cases, powerless to afford relief and the tumor stands as a bar
to the attainment of the utopia represented by a happy and comfortable
old age, and a quiet passing. Every possible resource should be placed
at the disposal of the scientific investigation of the subject, for
with knowledge will come power to relieve.
