Mammogram

What is the
test?
A mammogram is an x-ray of the breast used either
to screen for breast cancers that are too small
to be felt or to help determine if a lump felt
in the breast is caused by cancer or something
else. Mammography detects 85%-90% of breast cancers,
including tiny cancers that may measure less
than a quarter-inch. Generally, a lump can't
be felt until it's at least twice that size.
Most authorities agree that women should have
a mammogram every year starting at age 40; all
agree it should be done annually after age 50.

How
do I prepare for the test?
Avoid using deodorant or powder on your underarms
or breasts on the day of your mammogram because
they can make the x-ray picture hard to interpret.

What
happens when the test is performed?
Most mammograms are done at a hospital radiology
department or in a radiology office.You undress
from the waist up. Two pictures are usually taken
of each breast-one from the side and one from
the top. Before each picture is taken, your breast
will be pressed briefly and firmly but gently
between two flat plates for about 10 seconds
so that the tissue is spread out. This is necessary
for the x-ray to show a clear view of all areas
of the breast. You may find this part of the
procedure uncomfortable, but it doesn't last
long. If certain areas of the breast don't show
up clearly in the x-rays, the radiologist may
need to take additional views.

What
risks are there from the test?
Essentially none. Mammography uses very low
levels of radiation. There is no damage done
to the breast when it is pressed flat for the
pictures.

Must
I do anything special after the test is over?
No.

How
long is it before the result of the test is
known?
Some mammogram centers will give you a preliminary
report within 10 or 20 minutes, but most take
a few days to issue a final report. If the mammogram
suggests the presence of a mass or cyst, your
doctor will recommend additional tests, such
as a breast ultrasound, to collect more information.
