TRANSCRIPT
Cancer occurs when cellsin a part of the body begin
to grow uncontrollably. Normal cells divide and and grow in an orderly
fashion, but cancer cellsdo not. They continue to
grow and crowd out normal cells.
Different kinds of cancers
can behave very differently. They grow at
different rates and respond to different
treatments.
Sometimes cancer cells break away from a tumor
and spread to other parts of the body
through the blood and lymph system. They can settle in new places and
form new tumors.
When this happens, it is called metastasis.
Cancer that had spread in this way is called
metastatic cancer. As cancer spreads to other parts of the body, it is still named after the body part of origin.
Breast cancer is a malignant tumor that starts from cells of the
breast. It is found mostly in woman, but men can
get breast cancer as well.
A woman’s breast is made up of glands that
make breast milk, ducts, fatty and connective
tissue, blood vessels, and lymph vessels. Most
breast cancers begin in the cells that line the
ducts.
BREAST CANCER AWARENESS
The lymph system is important because it is
one of the ways in which breast cancers can
spread. Lymph nodes are small, bean-shaped
collections of immunes system cells that are
connected by lymphatic vessels.
Lymphatic vessels are like smalls veins, except they carry a clear fluid called lymph away from
the breast. Breast cancer cells can enter lymphatic
vessels and begin to grow in lymph nodes.
Most lymph vessels of the breast lead to lymph
nodes under the arm. Theses are called
axillary nodes. If breast cancer cells reach the underarm lymph nodes and continue to grow,
they cause the nodes to swell.
It is important to know whether cancer cells have spread to lymph nodes because if they have, there is a higher chance that the cells
have also gotten into the bloodstream and spread
to other places in the body.
Most lumps are benign. This means they are not
cancerous. Benign breast tumors are
abnormal growths, but they do not spread
outside of the breast and are not life threatening.
Some benign breast lumps can increase a
woman’s rick of getting breast cancer.
Most lumps are caused by fibrocystic changes.
Carcinoma: Used to describe a cancer that
begins in the lining later of organs such as the
breast. Nearly all cancers are known as
carcinoma.
Adenocarcinoma: Type of cancer that starts in glandular tissue. The
ducts and lobules of the breast are glandular tissue, so the cancer
starting in these areas are sometimes called
adenocarcinomas.
Carcinoma in situ: Early stage in cancer, when it
is still only in the layer of cancer where it began. In breast cancer, in situ means that the cancer
cells are only in the ducts or lobules. They have not spread into deeper tissues in the
breast.
Invasive carcinoma: Has already grown beyond the layer of cells where
it started.
Sarcoma: Cancers that start from connective tissues such as muscle
tissue, fat tissue, or blood vessels. Sarcomas
of the breast are very rare.
There are many types of breast, though some of them are uncommon.
Ductal carcinoma in situ: Most common types of
noninvasive breast cancer. DCIS means that the cancer is only in the ducts. It has not spread through the walls of the ducts into the tissue of
the breast. At this stage, the cancer can be cured.
Lobular carcinoma in situ: Begins in the milk-making glands but does not go through the wall of the lobules. Having
LCIS increases a woman’s rick of getting
cancer later. It is important that women
have regular mammograms.
Invasive ductal carcinoma: Most
common breast cancer. It starts in a milk
passage or duct, breaks through the wall of the duct, and invades the tissue of the breast.
From there it may be able to spread to other
parts of the body.
Invasive lobular carcinoma: Starts in the milk glands or lobules. It can spread to other parts
of the body.
Inflammatory breast cancer: This uncommon type of invasive breast
cancer accounts for about 1% to 3% of all
breast cancers. There is usually no single lump or tumor. It makes the skin
of the breast look red and feel warm.
It also gives the skin a thick, pitted appearance that looks a lot like an
orange peel. The affected breast may
become larger or firmer, tender or itchy.
In its early stages, inflammatory breast
cancer is mistaken for an infection.
Certain changes in DNA can cause normal breast cancer cells to become
cancerous. Some inherited DNA changes can increase the risk for developing cancer and are responsible for the
cancers that run in some families.
Most breast cancer DNA changes happen in single
breast cells during a woman’s life rather than having being inherited.
These are called acquired changes.
A risk factor is anything that affects a person’s
chance of getting a disease such as cancer. Different cancers have different risk factors.
Some risk factors, such as smoking, drinking, and diet are linked to things a person does.
Risk factors don’t tell us everything. Having a risk factor, or even several,
doesn’t mean that a person will get the disease. Some women who have one or
more risk factors never get breast cancer, and most women who get breast
cancer don’t have any risk factors.
Gender: Being a woman is the main
risk for breast cancer. Men can
also get the disease, but it is about 100
times more common in women then men.
Age: The chance of getting breast
cancer goes up as a woman gets older. About 2 out of 3
women are age 55 or older when the cancer is found.
Genetic Risk Factors: About 5-10% of breast cancers are thought to be linked to inherited mutations in certain genes. Women with these gene changes
have up to 80% chance of getting breast cancer in their
lifetimes.
Family History: Breast cancer risk is higher among those whose close blood relatives have this
disease; they can be from the mother’s or
the father’s side.
Personal History of Breast Cancer: A
woman with cancer in one breast has a greater chance of
getting a new cancer in the other breast
or in another part of the same breast.
Race: White women are slightly more likely than African-American women, but African-American women are more likely to die of
this cancer. Part of the reason seems to be because they have
faster growing tumors.
Dense Breast Tissue: This means there is more glandular tissue and less fatty tissue. Women with denser breast tissue have
a higher risk of breast cancer. It can also make it harder for doctors to
spot problems on mammograms.
Menstrual Periods: Women who began
having periods early, before age 12, or who went through
menopause after the age of 55 have a slightly increased
risk.
Earlier Breast Radiation: Women
who have had radiation treatment
to the chest area earlier in life have a
greatly increased risk of breast
cancer.
DES Exposure: DES is a drug once used to lower the risk of miscarriage. It is
now known to increase the risk of
breast cancer for the mother and the child
in the womb.
Not having children or having them later in life: Having a slightly higher risk for breast cancer, women who have no had children or had a child after
age 30. Being pregnant more than
once at early age reduces the number
some.
Recent use of birth control pills: Women who are using birth
control have a greater risk of breast cancer
than women who have never used it.
Therefore, before taking the pill, talk to your doctor about the
risks.
Alcohol: Use of alcohol is clearly linked to an
increased risk of getting breast cancer.
Having one drink a day decreases the risk only a small amount. Having 2-5 drinks a
day have 1½ times the risk of women who drink no alcohol.
Being overweight or obese: This is linked to a higher risk of breast cancer, especially if the weight gain took
place during adulthood. Also, the
risk seems to be higher if the fat exists
in the waist area.
Lack of exercise: Reduces breast
cancer risk. The only question is how much exercise is
needed. As little as 1 hour and 15 minutes to 2 hours per week reduces the risk by
18%.
Lowering your risk: The only way to lower you risk is by changing those factors that can be changed. Limit use
of alcohol, exercise regularly, and keep a healthy weight, you are decreasing your
risk.
Other than skin cancer, breast
cancer is the most common cancer
among women in the United States. After lung cancer, it is the
second leading cause of death.
In the past few years, 182,460 women in the
United States have been found with
invasive breast cancer. About 40,480 women die from the disease a year, and about 2 ½
million are survivors of the disease.
What Cancer Cannot DoCancer is so limited...
It cannot cripple love, It cannot shatter hope, It cannot corrode faith,
It cannot eat away at peace, It cannot destroy confidence,
It cannot kill friendship, It cannot shut out memories,
It cannot invade the soul, It cannot reduce eternal life, It cannot quench the spirit, It cannot lessen the power
of the resurrection.Anonymous
