Breast Cancer - How To Succeed
Overview
When a group of cells display uninhibited growth, which refers to
division beyond the normal limits, this phenomenon is commonly referred
to as cancer. Other characteristics include an attack and destruction
of surrounding tissues, and the spread to other locations in the body
via lymph or blood, which is known as metastasis.
These
malignant, which refers to a severe and progressively worsening
disease, properties of cancers differentiate them from benign tumors,
which are self-limited and do not invade or metastasise.
A tumor refers to a swelling or lesion formed by an unusually high
growth of cells and occurs with most cancers. However, some, like
leukemia, do not produce tumors.
Breast cancer becomes established, initially, in the cells of the
breast in men and women. On a worldwide basis, the second most
established form of cancer, after lung cancer, is that of breast
cancer. It represents 10% of all cancers relating to both sexes. It is
the fifth most common cause of cancer death.
The most common type of cancer specifically related to women,
globally, is that of breast cancer. It occurs at more than twice the
rate of that of colorectal cancer and cervical cancer and about three
times that of lung cancer. Further, in the case of women, deaths from
breast cancer, worldwide, is approximately 25% more than that from lung
cancer.
In a study in 2005, it was found that breast cancer produced 502,000
deaths worldwide. To get this into context, this represents about 7% of
all cancer deaths, and nearly 1% of all recorded deaths. Further, there
has been a substantial increase, globally, in breast cancer since the
1970s. This statistic, it is suggested, may be associated with modern
lifestyles in the western world.
On a global basis, the occurrence of breast cancer differs
significantly according to region. It is less widespread in
less-developed countries and more so in the further-developed
countries. In the twelve designated regions of the world, the annual
incidence rates per 100,000 women are as follows: Eastern Asia, 18;
Southern Central Asia, 22; sub-Saharan Africa, 22; South-Eastern Asia,
26; North Africa and Western Asia, 28; South and Central America, 42;
Eastern Europe, 49; Southern Europe, 56; Northern Europe, 73; Oceania,
74; Western Europe, 78; and in North America, 90.
The United States has the highest incidence rates of breast cancer
in women, globally. A study has shown 141 cases among white women and
122 among African American women. Also in the US, breast cancer amongst
women is the most prevalent cancer. After lung cancer, it produces the
second highest occurrence of deaths from all cancers.
There is a 12.5% chance of women in the US developing invasive
breast cancer within their lifetime. Further, there is a 3% chance that
the breast cancer that they may contract will actually cause their
death. A forecast has suggested that, in 2007, breast cancer would be
the cause of 40,910 deaths in the US. This would represent some 7% of
cancer deaths, and almost 2% of all deaths.
For the last few years, both the incidence and death rates from
breast cancer in the US have been in decline. In 2005, a study
conducted in the US by the Society for Women’s Health Research
concluded that breast cancer remains the disease that causes the most
concern. This is an interesting outcome since heart disease is a much
more widespread determinant when considering all deaths among women.
Breast cancer is also prevalent in men. This is due to the fact that
the breast is composed of identical tissues in respect of both genders.
However, it must be remembered that the manifestation of breast cancer
in men is some 100 times less common than that in women. Conversely,
men with breast cancer are considered to have the same statistical
survival rates as women.
