Hormone therapy is the use or manipulation of hormones natural or synthetic to treat disease. For example in prostate cancer some frequently used hormones are Eulexin and Flutamide. Hormone therapy is used in three ways:

Radiation therapy is the use of high-energy penetrating rays or
subatomic particles to treat or control cancer. Radiation can
be given in two ways, externally by a special machine, or internally,
by placing radioactive substances in the body. External radiation
is more commonly used and sometimes both methods are used.

Sometimes cancer patients experience bone pain, SVC
(superior vena cava) syndrome, or other symptoms that may or may not be
curative. If this happens radiation oncologists
may prescribe treatment and/or medication to alleviate the symptoms.
is the treatment or control of cancer using anticancer drugs,
highly toxic medications that destroy cancer cells by interfering
with their growth or by preventing their reproduction. Often times
these drugs are combined so that they are more effective in cancer
treatment. Some known combinations are cytarabine and doxorubicin
or doxorubicin and carmustine. Chemotherapy is also used to prolong
life when a cure is improbable and to relieve symptoms.
Biological therapy uses the immune system, either directly or
indirectly, to fight cancer or to lessen side effects that may
be caused by some cancer treatment. Biological therapies used
to treat cancer restore the body's natural cancer defense mechanisms,
reverse the process that changes a precancerous cell into a cancerous
cell, and prevent cancer cells from spreading to other parts of
Surgical removal of cancerous tumors is divided into several types
each serving their own individual purpose. They are as follows:
Staging surgery is performed to determine the extent of disease.
Based on the findings after this surgery, the oncologists selects
the procedure that would be most appropriate for this stage of
the disease. Staging is also used to eliminate radical procedures
such as hysterectomies, and prostatectomies.
Definitive surgery tries to remove as much of the tumor as possible. During this procedure the entire tumor as well as surrounding tissue are removed to try to prevent metastases. If done in the early stages, this surgery can cure some cancers.
Usually for patients with family history of cancer, or increased
risk of developing cancer, tissue where tumor is thought will
develop is removed.
Palliative surgery relieves symptoms in advanced stages of cancer
when medication does not work. Some procedures involved surgical
interruption of nerve pathways due to pain.
Besides the removal of the cancerous tumors many of the therapies
have side effects. Some are nausea, constipation, diarrhea, hair
loss, and vomiting. As a result, doctors have developed ways to
alleviate some of these side effects either through medication
or by following these simple steps:
-eat slowly and chew well
-eat dry foods like toast, dry cereal, and crackers
-drink clear unsweetened beverages
-breathe through mouth when feeling nausea
-try a clear liquid diet to give bowels a rest
-drink fluids to replace those lost
-eat smaller amounts of food more often
-avoid highly spiced foods a sweets
-avoid milk and milk products
-drink a lot of fluid
-eat high fiber foods
-keep up normal level of activity; exercise if possible
Sometimes the side effects are handled surgically such as the
reformation of breast after a mastectomy or the reconstruction
of a patient's face after face or neck treatment.

Apr 23, 2014 - The treatments for localized prostate cancer -- prostatectomy, brachytherapy, and external radiation -- have varied side effect profiles, and these should be taken into consideration in the selection of a treatment, according to a study published online June 9 in the Journal of the National Cancer Institute.
