What Is Breast Cancer Back
To Home Page
Warning:
This
is of vital importance. Often you will read that age is a factor
as a cause of cancer.
This
is true... however, there is never enough emphasis as to why. Age is
a factor because
the
older you get, the more susceptible to cancer you become... since your
immune system
who'se
job is to kill off cancer cells, has become severely weakened by all
sorts of toxins,
parasites,
pesticides, chemicals etc., so keep this in mind as you browse this
site.
If
you were to look up "breast" in the dictionary, you'd find
that it relates to the chest area. The reason
for such a broad definition is that both males
and females have chests and hence breasts, and both
males and females can get breast cancer.
The difference, however, between male
and female breast cancers and why women are more at
risk of developping breast cancer
is simply because of their make-up. Womens breasts is a gland designed
to make milk. The lobules in the breast make
the milk, which then drains through the ducts to the nipple.
Like all parts of your body, the cells
in your breasts usually grow and then rest in cycles. The periods
of growth and rest in each cell are controlled
by genes in the cell's nucleus. The nucleus is like the
control room of each cell. When your genes
are in good working order, they keep cell growth under
control. But when your genes develop an abnormality,
they sometimes lose their ability to control the
cycle of cell growth and rest. Breast
cancer then, is an uncontrolled growth of breast cells.
If that wasn't enough, the cancer has
the potential to break through normal breast tissue barriers and
spread to other parts of the body. While cancer
is always caused by a genetic "abnormality"
(a "mistake" in the genetic material),
only 5–10% of cancers are inherited from your mother or father.
Instead, 90% of breast cancers
are due to genetic abnormalities that happen as a result of the aging
process and shall I dare say "life
in general" or the "abuse of life in genneral".
While there are things every woman can
do to help her body stay as healthy as possible
(such as eating a balanced diet, not smoking,
minimizing stress, and exercising regularly), breast
cancer is never anyone's fault. Feeling
guilty, or telling yourself that breast cancer happened
because
of something you or anyone else did, is counter-productive.
There are different stages of breast
cancer and they can be briefly categorized as follows:
Stage 0 - This stage is used to describe non-invasive
breast cancer. There is no evidence of cancer
cells breaking out of the part of the breast
in which it started, or of getting through to or invading
neighboring normal tissue.
Stage I - This stage describes invasive
breast cancer (cancer cells are breaking through to
or invading neighboring normal tissue)
in which the tumor measures up to 2 centimeters, and no lymph nodes
are involved.
Stage II - This stage describes invasive
breast cancer in which the tumor measures at least
2
centimeters, but not more than 5 centimeters,
OR cancer has spread to the lymph nodes under the arm
on the same side as the breast cancer.
Affected lymph nodes have not yet stuck to one another or to
the surrounding tissues, a sign that the cancer
has not yet advanced to stage III. (The tumor in the
breast can be any size.)
Stage III - Stage III is divided into
subcategories known as IIIA and IIIB.
Stage IIIA - Stage IIIA describes invasive
breast cancer in which the tumor measures larger than
5 centimeters, OR there is significant
involvement of lymph nodes. The nodes clump together or stick to
one another or surrounding tissue.
Stage IIIB - This stage describes invasive
breast cancer in which a tumor of any size has spread
to the breast skin, chest wall, or internal
mammary lymph nodes (located beneath the breast right under the
ribs, inside the middle of the chest). Stage
IIIB includes inflammatory breast cancer, a very uncommon
but very serious, aggressive type of breast
cancer.
The most distinguishing feature of inflammatory
breast cancer is redness involving part or all of the
breast. The redness feels warm. You may
see puffiness of the breast's skin that looks like the peel of a navel
orange ("peau d'orange"), or even
ridges, welts, or hives. And part or all of the breast may be enlarged
and hard. A lump is present only half of the
time. Inflammatory breast cancer is sometimes misdiagnosed
as a simple infection.
Stage IV - This stage includes invasive
breast cancer in which a tumor has spread beyond the
breast, underarm, and internal mammary
lymph nodes, AND a tumor may have spread to the supraclavicular
lymph nodes (nodes located at the base of the
neck, above the collarbone), lungs, liver, bone, or brain.
"Metastatic at presentation"
means that the breast cancer has spread beyond the
breast and nearby
lymph nodes, even though this is the
first diagnosis of breast cancer. The reason for this
is that the primary breast
cancer was not found when it was only inside the breast. Metastatic
cancer is considered
stage IV.
