General Information
Although breast
cancer prophylaxis, including monthly breast self-examination, yearly
clinical breast examination and regular screening mammography, can not
prevent breast cancer development, the cause of which is unknown, it may
detect breast cancer in early, metastases free stages, while the tumour is
small enough to be successfully treated.
Although breast
cancer in women under 35 years of age is rare, and its incidence increases
after 50, no one can give you a guarantee that you will not find yourself
among those who are affected by it, so arm yourself with a tool that may
help you survive.
Facts
-
Each
year, worldwide, there are about one million new cases of breast cancer
and around five hundred thousand women die from it.
-
The
lifetime risk (from birth to death) of developing breast cancer for a
woman in United States is one out eight, in Canada - one out in nine.
-
Eighty
percent of women who develop breast cancer have no family history of the
disease.
-
Cancer is
the leading cause of death among women ages 40 to 79 and of those women,
who have cancer; breast cancer is the main killer at ages 20 to 49
years, and lung cancer ranks first at age 50 years and older.
-
Breast
cancer continues to lead in incidence among women, close to twice as
many new cases as lung cancer; however lung cancer will continue as the
leading cause of cancer death in 2009 among women living in North
America.
-
In 2009
year an estimated 192,370 new cases of invasive breast cancer will be
diagnosed among women in the United States and additional carcinoma in
situ (CIS) - a noninvasive and earliest form of breast cancer, accounts
for about 62,280 new cases each year. In 2009 an estimated 22,720
women will be diagnosed of breast cancer in Canada
-
Breast
cancer also occurs in men. An estimated 1,910 cases of invasive breast
cancer will be diagnosed in men in this year in US and 180 in Canada
-
In 2009,
about 40,170 women and 440 men will die from breast cancer in the United
States. In Canada an estimated 5350 women and 50 men will die from it in
2009
-
On
average, every week 437 Canadian women will be diagnosed with breast
cancer and 104 will die from it
-
Women
living in North America have the highest rate of breast cancer in the
world.
-
More than
95 percent of women whose breast cancer is found and treated in the
early stage have a chance of surviving.
At this time there are slightly over 2 million breast cancer survivors
in the United States. In Canada 1.0% of the female population are
survivors of breast cancer, diagnosed within the previous 15
years.

Risk Factors
Risk for developing breast cancer is individual. It depends on a combination
of lifestyle and personal traits known as "risk factors." The following risk
factors are strongly related to the disease and can alert you and your
physician to the need for careful follow-up:
-
Personal
history of breast cancer. Women who have had breast cancer face an
increased risk of getting breast cancer in their other breast.
-
Genetic
alterations. Hereditary breast cancer makes up approximately 5% to 10%
of all breast cancer. Some altered genes related to breast cancer are
more common in certain ethnic groups. Changes in certain genes (BRCA1,
BRCA2, and others) increase the risk of breast cancer.
Men who have an altered gene related to breast cancer also have an
increased risk of developing this disease.
Tests have been developed that can detect altered genes. These genetic
tests are sometimes done for members of families with a high risk of
cancer.
-
A family history of breast cancer, especially in your
mother, sister(s), or daughter(s)
-
Age - in general, the older you are, the greater your
risk
-
First menstrual period at an early age (before age
12)
-
Late menopause
(after age 55)
-
Hormone
replacement therapy for long periods of time
-
Never having borne a child
-
Having your first child after age 30
-
A history of benign breast disease that required
biopsies
-
Other breast conditions: lobular carcinoma in situ (LCIS)
or atypical hyperplasia.
-
Radiation therapy. Women whose breasts were exposed to radiation during
radiation therapy before age 30, especially those who were treated with
radiation for Hodgkin's disease, are at an increased risk for developing
breast cancer
-
Breast tissue that is dense on a mammogram.
Because only a direct relationship between breast cancer development
and certain characteristics called risk factors can only be found in a
certain percentage of women (20-30 %), debating them is not only common but
also important since the idea behind prophylaxis is, in reality, about
lowering the level of breast cancer development, especially by controlling
those factors which can be influenced.
If you think you
may be at risk, you should discuss this concern with your doctor. Your
doctor may be able to suggest ways to reduce your risk and can plan a
schedule for checkups.
