Diagnosing
Breast Cancer
Early
diagnosis is important in breast cancer treatment and survival.
The
odds of surviving are better the earlier the cancer is found and
treated.
Staging
of breast cancer refers to the size of the tumor and whether the
tumor has moved outside of the breast. Lower stages mean a smaller
tumor that has infected less other tissue. These statistics from
the American Cancer Society show how finding a breast cancer tumor
at an early stage can improve your chances of survival.

Remember
that statistics are averages and not a prediction of your future.
Many people who are diagnosed with breast cancer at Stage IV will
live for decades and pass on from some other cause. However, the
earlier a cancer is detected, the better the odds are to wind up
in the survivors group.

Tools
For Diagnosis
- A
MAMMOGRAM is a type of x-ray that creates an image of the breast
on film or paper. It can help determine whether a lump is benign
or cancerous. In fact, it can sometimes detect cancer in the breast
before a lump can be felt. The National Cancer Institute (NCI)
suggests that beginning at age 40, all women should have a mammogram
every 1 to 2 years. When a woman reaches 50, she should have a
mammogram each year. A doctor may also recommend a mammogram if
any sign or symptom of breast cancer is found, regardless of age.
Several
other methods also are being studied. None is now reliable enough
to be used alone, but they may be helpful when combined with approved
methods.

- DUCTAL
LAVAGE is a minimally invasive method of searching for abnormal
cells inside the milk ducts, where most breast cancer begins.
If abnormal cells are found, it provides physiological evidence
of significantly increased breast cancer risk. Determining whether
abnormal (or "atypical") cells are present can help
high-risk women and physicians weigh the risks and benefits of
options such as closer surveillance and risk reduction drug therapy.

- DIAPHANOGRAPHY,
or TRANSILLUMINATION, shines a light through the breast to show
its inner features. This technique is based on the principle that
different types of tissues (i.e., cancerous and normal tissues)
will manifest different patterns of light scatter and absorption;
therefore, the transmission of light through the breast will vary
in identifiable ways.

- THERMOGRAPHY
or DIGITAL INFRARED IMAGING measures the heat patterns in the
breast to produce an image. This procedure was approved by the
U.S. Food and Drug Administration (FDA) in 1982 as a supplement
to mammography in helping to detect breast cancer.

- ULTRASOUND
uses high-frequency sound waves forming
a pattern of echoes that are electronically translated into a
visual image to
get an image of the breast. The
sound waves (ultrasound) are bounced off tissues and the echoes
are converted into a picture (sonogram). Ultrasonography
can help determine if a lump is a cyst or a solid mass. It is
usually used along with palpation and mammography.
