If cancer of the lip or oral cavity is found, more tests will be done to find
out if cancer cells have spread to other parts of the body. This process is
called staging, and it helps the doctor plan the patient’s treatment. The
following stages are used for cancer of the lip and oral cavity:
Stage I: The cancer is no more than two centimeters (about one inch)
and has not spread to lymph nodes in the area. (Lymph nodes are small bean-shaped
structures that are found throughout the body; they produce and store infection-fighting
cells.)
Stage II: The cancer is more than two centimeters but less than four
centimeters (less than two inches) and has not spread to lymph nodes in the
area.
Stage III: Either of the following may be true:
The cancer is more than four centimeters.
The cancer is any size but has spread to only one lymph node on the same
side of the neck as the cancer. The lymph node that contains cancer measures
no more than three centimeters (just over one inch).
Stage IV: Either of the following may be true:
The cancer has spread to tissues around the lip and oral cavity. The lymph
nodes in the area may or may not contain cancer.
The cancer is any size and has spread to more than one lymph node on the
same side of the neck as the cancer or to lymph nodes on one or both sides
of the neck or to any lymph node that measures more than six centimeters (over
two inches).
The cancer has spread to other parts of the body.
Recurrent: Recurrent cancer is cancer that has come back (recurred)
after it has been treated. It may come back in the lip or oral cavity or in
another part of the body.
For specific cancers in the lip and oral cavity, the following treatments may
be used:
Lip Cancer

testing micrographic surgery followed by radiation therapy.
Stage II: Treatment may be surgery, external and/or internal radiation therapy,

About the Treatments and Side Effects
There are two primary treatments for patients with cancer of the lip and oral
cavity:
Chemotherapy is being tested in clinical trials. Hyperthermia
is a new treatment used for some patients.
Because the lips and mouth are needed to eat and talk, patients may need special
help adjusting to the side effects of the cancer and its treatment. The doctor
will consult with several kinds of doctors who can help determine the best treatment
for the patient. Trained medical staff can also help the patient recover from
treatment and adjust to new ways of eating and talking. The patient may need
plastic surgery or help learning to eat and speak if a large part of the lip
or mouth is taken out.
Surgery
Surgery is a common treatment for cancer of the lip and oral cavity. The doctor
may remove the cancer and some of the healthy tissue around the cancer. The
doctor may also remove the lymph nodes in the neck (lymph node dissection).
A new type of surgery called micrographic surgery is being tested for early
cancers of the lip and oral cavity. During this surgery, the doctor removes
the cancer and then uses a microscope to look at the area to make sure there
are no cancer cells left. This allows the doctor to target the cancer while
leaving as much normal tissue as possible in place.
Side effects of surgery: The side effects of surgery depend on the location
of the tumor and the type of operation, among other factors. Although patients
are often uncomfortable during the first few days after surgery, this pain can
usually be controlled with medicine. The recovery period after an operation
varies from patient to patient.
Radiation Therapy
Radiation therapy is the use of high-energy x-rays to kill cancer cells and
shrink tumors. Radiation may come from a machine outside the body (external
radiation therapy) or from putting materials that produce radiation (radioisotopes)
through thin plastic tubes into the area where the cancer cells are found (internal
radiation therapy). If the patients stops smoking before starting radiation
therapy, he or she will have a better chance of surviving longer.
Side effects of radiation therapy: The most common side effects of radiation
therapy are tiredness, skin reactions in the treated areas (such as a rash or
redness), and loss of appetite. Radiation therapy may also cause a decrease
in the number of white blood cells that help protect the body against infection.
Most of these side effects can be treated or controlled and in most cases they
are not permanent.
Chemotherapy
Chemotherapy is the use of drugs to kill cancer cells. Most anticancer drugs
are injected into a vein (IV) or a muscle; some are given by mouth. Chemotherapy
is a systemic treatment, meaning that the drugs flow through the bloodstream
to nearly every part of the body to kill cancerous cells. It is generally given
in cycles: A treatment period is followed by a recovery period, then another
treatment period, and so on.
If a doctor removes all the cancer that is visible at the time of the operation,
the patient may be given chemotherapy after surgery to kill any remaining cells.
Chemotherapy that is given after surgery to remove the cancer is called adjuvant
chemotherapy. Chemotherapy given before surgery to try to shrink the cancer
so it can be removed is called neoadjuvant chemotherapy.
Side effects of chemotherapy: Chemotherapy drugs generally fight rapidly
dividing cells in the body. Cells that divide rapidly include both the targeted
cancer cells and healthy cells in the blood, digestive tract, and hair follicles.
Depending on which anticancer drugs a patient receives, he or she may experience
symptoms when healthy cells are damaged along with the cancer cells. If healthy
blood cells are destroyed by chemotherapy, the patient may be more susceptible
to infections, bruising or bleeding, and fatigue. When cells in the hair roots
or digestive tract are affected by anticancer drugs, the patient may have hair
loss, nausea, vomiting, or mouth sores. Not all chemotherapy patients develop
all of these side effects, and the symptoms usually go away during the recovery
period or after the treatments are done. Doctors can prescribe medicines and
other treatments to control most of the symptoms.
Hyperthermia
Hyperthermia is a new treatment being tested in certain patients. It uses a
special machine to heat the body for a certain period of time to kill cancer
cells. Because cancer cells are often more sensitive to heat than normal cells,
the cancer cells die and the cancer shrinks.
