A Journey With Breast Cancer
A Journey with Breast Cancer What is Cancer? The body is made up of many
types of cells. Normally, cells grow and divide to produce more cells only when
the body needs them. This is an orderly process which keeps the body healthy.
Sometimes cells keep dividing when new cells are not needed. They may form a
mass of extra tissue called a growth or tumor. Benign tumors are not a threat to
life but malignant tumors are cancer. Cells in these tumors can invade and
damage nearby tissues and organs. The fear is that cancer cells can break away
from a malignant tumor and enter the bloodstream or lymphatic system. That is
how breast cancer spreads and forms other tumors in the body. The spread of
cancer is called metastisis. (Dollinger, Rosenbaum and Cable, 1991).
Understanding the breasts Each breast has 15 to 20 overlapping sections called
lobes. There are many smaller lobules, which end in dozens of tiny bulbs that
can produce milk. The lobes, lobules and bulbs are all linked by thin tubes
called ducts. These ducts lead to the nipple in the center of a dark area of
skin called the areola. Fat fills the spaces around the lobules and ducts. The
breast does not have muscles tissue but muscles lie under each breast and cover
the ribs. Each breast contains blood vessels and vessels that contain lymph. The
lymph vessels lead to small bean shaped organs called lymph nodes. Clusters of
lymph nodes are found near the breast under the arm, above the collarbone and in
the chest. They are also found in other parts of the body. (Dollinger, Rosenbaum
and Cable, 1991). Types of breast cancer According to Dollinger, Rosenbaum and
Cable (1991), the most common type of breast cancer begins in the lining of the
ducts It is called ductal carcinoma. Lobular carcinoma arises in the lobules.
They explain that when breast cancer spreads outside of the breast, cancer cells
are often found in the lymph nodes under the arm. If it reaches these nodes it
may mean that cancer cells have spread to other parts of the body, other lymph
nodes or other organs. It may have spread to the bones, liver or lungs. When
cancer spreads, it is called metastatic breast cancer. The median duration of
survival for women with metastatic disease is two to three years. Malignant
cells are transported via the lymphatic system.
Distant metastasis occurs when
the cancerous tumor cells break away from the primary tumor and spread to other
sites in the body. (McEvilly and Hassey, 1998). Risk factors for breast cancer
According to the National Cancer Institute (1999), research has shown that the
following conditions place a woman at increased risk for breast cancer: Personal
history of breast cancer - Women who have had breast cancer face an increased
risk of getting breast cancer again. Genetic alterations - Changes in certain
genes (BRCA1, BRCA2, and others) make women more susceptible to breast cancer.
In families in which many women have had the disease, gene testing can show
whether a woman has specific genetic changes known to increase the
susceptibility to breast cancer. Family history- A woman's risk for developing
breast cancer increases if her mother, sister, daughter or two or more other
close relatives, such as cousins, have a history of breast cancer, especially at
a young age. Certain breast changes - Having a diagnosis of atypical hyerplasia
or lobular carcinoma in situ (LCIS) or having had two or more breast biopsies
for benign conditions may increase a woman's risk for developing cancer. Breast
density - Women age 45 and older whose mammograms show at least 75 per cent
dense tissue are at increased risk. Dense breasts contain many glands and
ligaments, which makes breast tumors difficult to see and the dense tissue
itself is associated with developing breast cancer. Radiation therapy - Women
whose breasts were exposed to radiation during their childhood, especially those
who were treated with radiation for Hodgkin's disease, are at an increased risk.
Late childbearing - Women who had their first child after the age of 30 have a
greater chance of developing breast cancer than women who had their children at
a younger age. Early menstruation - Women who started menstruating at an early
age (before age 12), experienced menopause late (after age 55), never had
children, or took hormone replacement therapy or birth control pills for long
periods of time. Each of these factors increases the amount of time a woman's
body is exposed to estrogen. The longer this exposure, the more likely she is to
develop breast cancer. In most cases, doctors cannot explain why a woman
develops breast cancer. Studies show that most women who develop breast cancer
have none of the risk factors listed above. Also, women with known risk factors
may never develop breast cancer (Dollinger, Rosenbaum and Cable, 1991). Early
detection When breast cancer is found and treated early, the chances for
survival are better. Women can take an active part in the early detection by
having regular mammograms and breast exams. Self examination is also very
important. Mammograms can often detect cancer before it is felt. It can also
show calcium deposits which may be an early sign of cancer.
