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, with more than twice as many new cases as lung
cancer; however lung cancer will
continue as the leading cause of cancer death in 2007 among women living
in North America.
-
In 2007 year an estimated 178,480 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 62,030 new
cases each year. In Canada over 22,300 women will be diagnosed of
breast cancer
-
Breast cancer also occurs in men. An
estimated 2,030 cases of invasive breast cancer will be diagnosed in men
in this year in US and 170 in Canada
-
In 2007, about 40,460 women and 450 men
will die from breast cancer in the United States. In Canada this year
5300 women and 50 men 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.
