Breast
cancer
Breast cancer is cancer that forms in the cells of the breasts.
After skin cancer, breast
cancer is the most common cancer diagnosed in women in the United States.
Breast cancer can occur in both men and women, but it's far more common in
women.
Substantial support for
breast cancer awareness and research funding has helped created advances in the
diagnosis and treatment of breast cancer. Breast cancer survival rates have
increased, and the number of deaths associated with this disease is steadily
declining, largely due to factors such as earlier detection, a new personalized
approach to treatment and a better understanding of the disease.
Types
Angiosarcoma
Ductal carcinoma in situ
(DCIS)
Inflammatory breast cancer
Invasive lobular carcinoma
Lobular carcinoma in situ
(LCIS)
Male breast cancer
Paget's disease of the
breast
Recurrent breast cancer
Symptoms
Nipple changes
Signs and symptoms of breast
cancer may include:
A breast lump or thickening
that feels different from the surrounding tissue
Change in the size, shape or
appearance of a breast
Changes to the skin over the
breast, such as dimpling
A newly inverted nipple
Peeling, scaling, crusting
or flaking of the pigmented area of skin surrounding the nipple (areola) or
breast skin
Redness or pitting of the
skin over your breast, like the skin of an orange
When to see a doctor
If you find a lump or other
change in your breast — even if a recent mammogram was normal — make an
appointment with your doctor for prompt evaluation.
Causes
Doctors know that breast
cancer occurs when some breast cells begin to grow abnormally. These cells
divide more rapidly than healthy cells do and continue to accumulate, forming a
lump or mass. Cells may spread (metastasize) through your breast to your lymph
nodes or to other parts of your body.
Breast cancer most often
begins with cells in the milk-producing ducts (invasive ductal carcinoma).
Breast cancer may also begin in the glandular tissue called lobules (invasive
lobular carcinoma) or in other cells or tissue within the breast.
Researchers have identified
hormonal, lifestyle and environmental factors that may increase your risk of
breast cancer. But it's not clear why some people who have no risk factors
develop cancer, yet other people with risk factors never do. It's likely that
breast cancer is caused by a complex interaction of your genetic makeup and
your environment.
Inherited breast
cancer
Doctors estimate that about
5 to 10 percent of breast cancers are linked to gene mutations passed through
generations of a family.
A number of inherited
mutated genes that can increase the likelihood of breast cancer have been
identified. The most well-known are breast cancer gene 1 (BRCA1) and breast
cancer gene 2 (BRCA2), both of which significantly increase the risk of both
breast and ovarian cancer.
If you have a strong family
history of breast cancer or other cancers, your doctor may recommend a blood
test to help identify specific mutations in BRCA or other genes that are being
passed through your family.
Consider asking your doctor
for a referral to a genetic counselor, who can review your family health
history. A genetic counselor can also discuss the benefits, risks and
limitations of genetic testing to assist you with shared decision-making.
Risk factors
A breast cancer risk factor
is anything that makes it more likely you'll get breast cancer. But having one
or even several breast cancer risk factors doesn't necessarily mean you'll
develop breast cancer. Many women who develop breast cancer have no known risk
factors other than simply being women.
Factors that are associated
with an increased risk of breast cancer include:
Being female. Women are much
more likely than men are to develop breast cancer.
Increasing age.
Your risk of breast cancer increases as you age.
A personal history of breast
conditions. If you've had a breast biopsy that found lobular carcinoma in situ
(LCIS) or atypical hyperplasia of the breast, you have an increased risk of
breast cancer.
A personal history of
breast cancer. If you've had breast cancer in one breast,
you have an increased risk of developing cancer in the other breast.
A family history of
breast cancer. If your mother, sister or daughter was
diagnosed with breast cancer, particularly at a young age, your risk of breast
cancer is increased. Still, the majority of people diagnosed with breast cancer
have no family history of the disease.
Inherited genes that
increase cancer risk. As discussed above, certain
gene mutations that increase the risk of breast cancer can be passed from
parents to children. The most well-known gene mutations are referred to as
BRCA1 and BRCA2. These genes can greatly increase your risk of breast cancer
and other cancers, but they don't make cancer inevitable.
Radiation exposure. If
you received radiation treatments to your chest as a child or young adult, your
risk of breast cancer is increased.
Obesity. Being obese
increases your risk of breast cancer.
Beginning your period
at a younger age. Beginning your period before age 12 increases
your risk of breast cancer.
Beginning menopause
at an older age. If you began menopause at an older
age, you're more likely to develop breast cancer.
Having your first
child at an older age. Women who give birth to
their first child after age 30 may have an increased risk of breast cancer.
Having never been
pregnant. Women who have never been pregnant have a
greater risk of breast cancer than do women who have had one or more
pregnancies.
Postmenopausal
hormone therapy. Women who take hormone therapy
medications that combine estrogen and progesterone to treat the signs and
symptoms of menopause have an increased risk of breast cancer. The risk of
breast cancer decreases when women stop taking these medications.
Drinking alcohol.
Drinking alcohol increases the risk of breast cancer.
Prevention
Making changes in your daily
life may help reduce your risk of breast cancer. Try to:
Ask your doctor about
breast cancer screening. Discuss with your doctor
when to begin breast cancer screening exams and tests, such as clinical breast
exams and mammograms.
Talk to your doctor about
the benefits and risks of screening. Together, you can decide what breast
cancer screening strategies are right for you.
Become familiar with
your breasts through breast self-exam for breast awareness.
Women may choose to become familiar with their breasts by occasionally
inspecting their breasts during a breast self-exam for breast awareness. If
there is a new change, lumps or other unusual signs in your breasts, talk to
your doctor promptly.
Breast awareness can't
prevent breast cancer, but it may help you to better understand the normal
changes that your breasts undergo and identify any unusual signs and symptoms.
Drink alcohol in
moderation, if at all. Limit the amount of alcohol you
drink to no more than one drink a day, if you choose to drink.
Exercise most days of
the week. Aim for at least 30 minutes of exercise on
most days of the week. If you haven't been active lately, ask your doctor
whether it's OK and start slowly.
Limit postmenopausal
hormone therapy. Combination hormone therapy may
increase the risk of breast cancer. Talk with your doctor about the benefits
and risks of hormone therapy.
Some women experience
bothersome signs and symptoms during menopause and, for these women, the
increased risk of breast cancer may be acceptable in order to relieve menopause
signs and symptoms.
To reduce the risk of breast
cancer, use the lowest dose of hormone therapy possible for the shortest amount
of time.
Maintain a healthy
weight. If your weight is healthy, work to maintain
that weight. If you need to lose weight, ask your doctor about healthy
strategies to accomplish this. Reduce the number of calories you eat each day
and slowly increase the amount of exercise.
Choose a healthy diet.
Women who eat a Mediterranean diet supplemented with extra-virgin olive oil and
mixed nuts may have a reduced risk of breast cancer. The Mediterranean diet
focuses mostly on plant-based foods, such as fruits and vegetables, whole
grains, legumes, and nuts. People who follow the Mediterranean diet choose
healthy fats, such as olive oil, over butter and fish instead of red meat.
Breast cancer risk
reduction for women with a high risk
If your doctor has assessed
your family history and determined that you have other factors, such as a
precancerous breast condition, that increase your risk of breast cancer, you
may discuss options to reduce your risk, such as:
Preventive
medications (chemoprevention). Estrogen-blocking
medications, such as selective estrogen receptor modulators and aromatase
inhibitors, reduce the risk of breast cancer in women with a high risk of the
disease.
These medications carry a
risk of side effects, so doctors reserve these medications for women who have a
very high risk of breast cancer. Discuss the benefits and risks with your
doctor.
Preventive surgery.
Women with a very high risk of breast cancer may choose to have their healthy
breasts surgically removed (prophylactic mastectomy). They may also choose to
have their healthy ovaries removed (prophylactic oophorectomy) to reduce the
risk of both breast cancer and ovarian cancer.
