so be used in removing tumors with small attachments.
This not only stops the bleeding but forms a firm scab, under which healing
may occur rapidly. Those tumors that can not be removed by the above
methods may be treated with caustics or acids, such as sulphuric acid,
hydrochloric acid, caustic potash, arsenic, silver nitrate, or chromic
acid, but it is difficult to limit the action of these drugs. The
injection, into the tumor, of such chemicals as anilin dyes, alcohol,
acetic acid, citric acid, or ergotin, is of doubtful value, as is also the
injection of the germs of erysipelas--thought by some to be a specific.
Certain specific tumors, such as actinomycosis and botryomycosis, may be
successfully treated by the internal administration of potassium iodid,
together with the injection into the tumor or the painting of its surface
with either Lugol's solution or the tincture of iodin. The most reliable
means of treating tumors is by extirpation with cutting instruments.
Dissect the tumor from the surrounding tissue, ligating all the larger
blood vessels, and tearing the tissues with the fingers rather than cutting
with a knife. The bleeding may be stopped with a hot iron. The after
treatment is the same as for any ordinary wound of similar size.
DESCRIPTION OF INDIVIDUAL TUMORS.
Although a full list of the tumors that may be found in bovines has been
given above, there are a number that warrant a detailed description, and
the following mention will be made of the most important of them:
MYOMA.
These tumors are after the type of muscle. They are sharply circumscribed
and, as a rule, are very hard, a condition owing usually to combination
with fibroma and are then known as fibromyoma. In fact, the clinical
differentiation between myoma and fibroma is almost impossible. Myomas are
found in the uterus, vagina, stomach, intestines, gullet, and bladder of a
bovine animal. They grow very large, but, as a rule, are benign. Treatment
should consist of their removal.
NEUROFIBROMA.
A true neuroma built up of nerve fibers and nerve cells is infrequent, if
it ever occurs, in cattle. False neuromas, or neurofibromas, are knotty,
spreading tumors of the size of a large potato, which are developed within
the nerve sheaths and composed of nerve fibers and connective tissue bands
interlaced. The commingling of these varied fibers is often so intricate
that separation is practically impossible. This tumor is most frequent
