Definition of Cancer

What is cancer?

The body is made up of trillions of living cells. Normal body
cells grow, divide, and die in an orderly way. During the early
years of a person's life, normal cells divide faster to allow the
person to grow. After the person becomes an adult, most cells
divide only to replace worn-out, damaged, or dying cells.
Cancer begins when cells in a part of the body start to grow
out of control. There are many kinds of cancer, but they all
start because of this out-of-control growth of abnormal cells.

Breast Cancer Screening
The Data





Not counting some kinds of skin cancer, breast cancer
in the United States is:
The most common cancer in women, no matter your
race or ethnicity.
The most common cause of death from cancer among
Hispanic women.
The second most common cause of death from cancer
among white, black, Asian/Pacific Islander, and
American Indian/Alaska Native women.

The Data
2011 estimates for US Women


230,480 new cases of invasive breast cancer were expected
to be diagnosed
in 2011
57,650 new cases of carcinoma in situ (CIS) were expected to
be found (CIS is non-invasive and is the earliest form of breast
cancer).

About 39,520 deaths from breast cancer were expected in

Who is at risk?

Research has found several risk factors that may increase your
chances of getting breast cancer, including:
Getting older.
Being younger when you first had your menstrual period.
Starting menopause at a later age.
Being older at the birth of your first child.
Never giving birth.
Not breastfeeding

Who is at risk?

Personal history of breast cancer or some non-cancerous breast
diseases.
Family history of breast cancer (mother, sister, daughter).
Treatment with radiation therapy to the breast/chest.
Being overweight (increases risk for breast cancer after
menopause).
Long-term use of hormone replacement therapy (estrogen and
progesterone combined).
Drinking alcohol (more than one drink a day).
Not getting regular exercise

Symptoms


Breast cancer symptoms vary widely — from
lumps to swelling to skin changes — and many
breast cancers have no obvious symptoms at
all. Symptoms that are similar to those of
breast cancer may be the result of noncancerous conditions like infection or a cyst.

Screening

Diagnosis is a process than can take several
weeks .Breast self-exam (BSE) should be part
of your monthly health care routine, and you
should visit your doctor if you experience
breast changes. BSE is recommended for
women beginning in their twenties.
Screening

Between ages 20-30 years you should have a
clinical breast exam done by a health provider
every 3 years.
Screening


If you're over 40 or at a high risk for the
disease, you should also have an annual
mammogram and physical exam by a doctor.
The earlier breast cancer is found and
diagnosed, the better your chances of beating
it.
http://www.breastcancer.org/symptoms/
Screening

Mammogram. A mammogram is an X-ray of the breast.
Mammograms are the best method to detect breast cancer early
when it is easier to treat and before it is big enough to feel or
cause symptoms. Having regular mammograms can lower the
risk of dying from breast cancer. If you are age 50 to 74 years,
be sure to have a screening mammogram every two years. If
you are age 40–49 years, talk to your doctor about when and
how often you should have a screening mammogram.

Prostate Cancer

About the Prostate


The prostate is a gland found only in males. It is
located in front of the rectum and below the urinary
bladder. In younger men, it is about the size of a
walnut, but it can be much larger in older men.
The prostate's job is to make some of the fluid that
protects and nourishes sperm cells in semen, making
the semen more liquid. Just behind the prostate are
glands called seminal vesicles that make most of the
fluid for semen. The urethra, which is the tube that
carries urine and semen out of the body through the
penis, goes through the center of the prostate
American Cancer Society

Who is at risk?

Age
The chances of having prostate cancer rises rapidly after 50
2 out 0f 3 men over the age of 65 are found to have prostate
cancer.

Race/ethnicity
Prostate cancer occurs more often among African American men
More likely to be diagnosed at an advanced stage
African American men are 2-3 times more likely to die from prostate cancer
than white men
American Cancer Society
http://www.cancer.org/Cancer/ProstateCancer/DetailedGuide/prostate-cancer-what-is-prostate-cancer
Who is at risk?

Family History
Having a father or brother with prostate cancer more than doubles a man’s risk
of developing the disease

Genes
Recently studies have found some common genes variations have been linked
to a higher risk of prostate cancer, however, gene testing for most genes
changes is not yet avaialble

Diet
The exact role of diet in prostate cancer is not clear.

Who is at risk?

Obesity
Relationship unknown-no firm conclusions

Smoking
Relationship unknown-no firm conclusions

Sexually Transmitted Infections
Relationship unknown-no firm conclusions
Vasectomy
Men who have had a vasectomy before the age of 35 may have a
slightly higher risk of developing prostate cancer
Symptoms




In the early stages there are usually no
symptoms.
In the more advanced stages-urinary frequency
especially at night
In the very advanced cases-blood in urine or
impotence
The symptoms can also be consistent with
other conditions other than prostate cancer
Screening for Prostate Cancer

Screening should take place at age 50 for men
with an average risk for prostate cancer and
age 45 for men at high risk this includes
African American men and men who have a
first degree relative who had the disease at an
earlier age.


Screening for Prostate Cancer



Screening includes a digital rectal examination
and prostate-specific antigen (PSA) blood test.
Men with a PSA less than 2.5 may only need
to be retested every 2 years
Men with a PSA greater than 2.5 should be
tested yearly.
Cervical Cancer




Described by Papanicolaou in 1940’s
Malignant transformation of cervical epithelial cells
Begins in “Transformation Zone” “TZ”
between original cervical canal glands & squamous
cells lining the outer cervix
“Squamocolumnar junction” or SCJ
Invasive cervical cancer final stage in a series of
abnormal changes in cervical cells

Lung Cancer
Lung Cancer Data

Lung cancer is the leading cause of cancer death in the U.S. It is the most
common cancer in men and women combined, after skin cancer. Lung
cancer (both small cell and non-small cell) is by far the leading cause of
cancer death for both men and women. More people die of lung cancer than
of colon, breast, and prostate cancers combined. Lung cancer is fairly rare
in people under the age of 45.

The average lifetime chance that a man will develop lung cancer is about 1
in 13. For a woman it is 1 in 16. These numbers include both smokers and
non-smokers. For smokers the risk is much higher, while for non-smokers
the risk is lower.


Lung Cancer Data



The American Cancer Society's most recent
estimates for lung cancer (both small cell and
non-small cell) in the United States are for
2012:
About 226,160 new cases of lung cancer (both
small cell and non-small cell)
About 160,340 deaths from lung cancer
Who is at Risk?
Smoking is by far the leading risk
factor causing 8 out 10 cases of lung
cancer.

Symptoms

The most common symptoms of lung cancer are:
A cough that does not go away or gets worse
Chest pain, often made worse by deep breathing, coughing, or laughing
Hoarseness
Weight loss and loss of appetite
Coughing up bloody or rust-colored sputum (spit or phlegm)
Shortness of breath
Feeling weak or tired
Infections such as bronchitis and pneumonia that don’t go away or keep coming
back
New onset of wheezing

Screening

Until recently, no lung cancer screening test had been shown
to lower the risk of dying from this disease. Studies of 2
possible screening tests, chest x-ray and sputum cytology, did
find that these tests detected lung cancers at an early stage, but
neither test helped patients live longer. For this reason, major
medical organizations have not recommended routine
screening with these tests for the general public or even for
people at increased risk, such as smokers. Recently, though, a
different lung cancer screening test has been shown to help
lower the risk of dying from this disease.
