BREAST CANCER SCREENING
GROUP 41
SHAMS ATRASH
WHAT ARE SCREENING TESTS?
• Screening refers to tests and exams used to find a disease in people who don’t have
any symptoms.
• Early detection means finding and diagnosing a disease earlier than if you’d waited
for symptoms to start.
• Although breast cancer screening cannot prevent breast cancer, it can help find
breast cancer early, when it is easier to treat.
Early detection is
best protection! 
Factors to assess risk category:
• Age
• Genes
• Family history
• Breast density
 The algorithm in which we start screening all
relies on the risk category that the individual’s is in
• Women aged 40 to 44 years should have the choice to start breast cancer screening once a year
with mammography if they wish to do so.
(The risks of screening as well as the potential benefits should be considered)
• Women aged 45 to 49 years should be screened with mammography annually.
• Women aged 50 to 54 years should be screened with mammography annually.
• women aged 55 years and older, screening with mammography is recommended once every
two years or once a year.
• Women aged 75 years or older with average risk should continue screening with mammography
as long as their overall health is good and they have a life expectancy of 10 years or more
• Women with dense breasts: Evidence is insufficient to recommend for or against yearly MRI
screening.
Women with average risk
WOMEN WITH HIGH RISK OF DEVELOPING BREAST
CANCER!
Women who are at high risk for breast cancer based on certain factors should get
a breast MRI and a mammogram every year, typically starting at age 30.
• Have a lifetime risk of breast cancer of about 20% to 25% or greater.
• Have a known BRCA1 or BRCA2 gene mutation.
• Have a first-degree relative (parent, brother, sister, or child) with a BRCA1 or BRCA2 gene
mutation, and have not had genetic testing themselves
• Had radiation therapy to the chest when they were between the ages of 10 and 30 years
• Have Li-Fraumeni syndrome, Cowden syndrome, or Bannayan-Riley-Ruvalcaba syndrome, or have
first-degree relatives with one of these syndromes
 Bannayan–Riley–Ruvalcaba syndrome (BRRS) is a rare overgrowth
syndrome and hamartomatous disorder with occurrence of multiple
subcutaneous lipomas, macrocephaly and hemangiomas.
Mutation of the PTEN gene underlies this syndrome, as well as Cowden syndrome, Proteus syndrome,
and Proteus-like syndrome, these four syndromes are referred to as PTEN Hamartoma-Tumor
Syndromes.
MAMMOGRAMS
• Mammograms are low-dose x-rays that can help find breast cancer, 2
main types of breast changes found with a mammogram
are calcifications and masses.
• machine has 2 plates that compress or flatten the breast to spread
the tissue apart. This gives a better picture and allows less radiation
to be used.
• More pictures are taken during a diagnostic mammogram with a
focus on the area that looked different on the screening
mammogram.
• mammogram report will also contain an assessment of your breast
density, Dense breasts are not abnormal, but they are linked to a
higher risk of breast cancer. Dense breast tissue can also make it
harder to find cancers on a mammogram. ( with aging density
usually is less, high density calls for using ultrasound).
• https://youtu.be/XzAgfCIX2JY
MAMMOGRAM POSSIBLE FINDINGS
Calcifications: tiny calcium deposits within the breast tissue. They look like small white spots
on a mammogram. They may or may not be caused by cancer. There are 2 types of
calcifications.
• Macrocalcifications: are larger calcium deposits that are most likely due to changes
caused by aging of the breast arteries, old injuries, or inflammation, are typically related to
non-cancerous conditions and don’t need to be checked for cancer with a biopsy,(more
common as women get older).
• Microcalcifications: are tiny specks of calcium in the breast, they are more of a concern
than macrocalcifications, but they don’t always mean that cancer is present.
•  In most cases, microcalcifications don’t need to be checked with a biopsy. But if they have
a suspicious look and pattern, a biopsy will be recommended to check for cancer.
• Masses: an area of dense breast tissue with a shape and edges that make it look different
than the rest of the breast tissue,Masses can be many things, including cysts (non-
cancerous, fluid-filled sacs) and non-cancerous solid tumors (such as fibroadenomas), but
they may also be a sign of cancer.
• A cyst and a solid mass can feel the same, can also look the same on a mammogram, thus
the doctor must be sure it’s a cyst or not so a breast ultrasound is made, Another option is
to use a needle to aspirate fluid from the area.
Breast density in mammograms
More of the breast is made of
dense glandular and fibrous
tissue (described as
heterogeneously dense). This
can make it hard to see small
tumors in or around the dense
tissue.
Breasts are extremely
dense, which makes it hard
to see tumors in the tissue.
Breasts are almost
all fatty tissue.
There are scattered
areas of dense
glandular and fibrous
tissue.
BI-RADS ASSESSMENT CATEGORY
• BI-RADS 0 refers to the need of redoing
a new mammogram or even an
ultrasound.
• BI-RADS 3 refers to the need of an near
follow up within 6 months.
• BI-RADS 4/5 they needs taking biopsy for
conformation.
• BI-RADS usually for follow up the
effectivity of a treatment given for a
breast cancer patient (follow up).
BREAST ULTRASOUND
• Breast ultrasound uses sound waves to make a computer
picture of the inside of the breast.
• It can show certain breast changes, like fluid-filled cysts, that
are harder to identify on mammograms.
• Used in women with dense breast.
• Ultrasound is useful because it can often tell the difference
between fluid-filled cysts and solid masses.
• Ultrasound can also be used to help guide a biopsy.
• Ultrasound is widely available, easy to have, and does not
expose a person to radiation. It also costs less than a lot of
other options.
• Automated breast ultrasound (ABUS) is an option that uses
a much larger transducer to take hundreds of images that
cover nearly the entire breast. When ABUS is done, a
second handheld ultrasound is often needed to get more
pictures of suspicious areas.
Hyperechoic – more echogenic (brighter) than
normal
Hypoechoic – less echogenic (darker) than
normal
Isoechoic – the same echogenicity as another
tissue
Anechoic – The term is usually used in
medicine ,when discussing images of body
parts that appear black on.

BREAST MAGNETIC RESONANCE IMAGING (MRI)
• A breast MRI uses magnets and radio waves to take pictures of the breast. MRI is used along with
mammograms to screen women who are at high risk for getting breast cancer.
• breast MRIs may appear abnormal even when there is no cancer, they are not used for women at average risk.
• help measure the size of the cancer, look for other tumors in the breast, and to check for tumors in the
opposite breast.
• not every woman who has been diagnosed with breast cancer needs a breast MRI.
• screening MRI is recommended along with a yearly mammogram.
• Before the test, you need to have a contrast solution (dye) injected into your arm through an intravenous line
• MRI is not a replacement for mammography
• https://www.youtube.com/watch?v=S16eUPbZ1Zo
CT-SCAN + PET
• is an X-ray technique that gives doctors information about the
body’s internal organs in 2-dimensional slices, or cross-sections.
• Before the test, you need to have a contrast solution (dye) injected
into your arm through an intravenous line
• CT scans are not used routinely to evaluate the breast
• CT scans to examine other parts of the body where breast cancer
can spread, such as the lymph nodes, lungs, liver, brain, spine.
• CT scans is used during treatment to see whether or not the cancer
is responding.
• positron emission tomography: a form of radioactive sugar (called
FDG) is put into a vein and travels throughout the body. Cancer
cells absorb high amounts of this sugar. A special camera then
takes pictures that show the areas where the sugar collected
throughout the body. A PET scan is often combined with a CT scan
(known as a PET/CT scan)
NEWER AND EXPERIMENTAL BREAST IMAGING
TESTS
• Molecular breast imaging (MBI)
• Positron emission mammography (PEM)
• Contrast-enhanced mammography (CEM)
• Optical imaging tests
• Electrical impedance imaging (EIT)
• Elastography
MOLECULAR BREAST IMAGING (MBI)
• is a type of nuclear medicine imagining test for the
breast.
• A radioactive chemical is injected into the blood, and
a special camera is used to see into the breast. This
test is being studied mainly as a way to follow up
breast problems (such as a lump or an abnormal
mammogram), or to help determine the extent of
breast cancer that has already been diagnosed.
• It’s also being studied as a test that can be used
along with mammograms to look for cancer in
women with dense breast.
• Due to exposing the whole body to radiation, so it’s
unlikely this test would be used for screening every
year.
POSITRON EMISSION MAMMOGRAPHY (PEM)
• is very similar to a PET SCAN, A form of sugar attached to a radioactive particle is injected into the blood
to detect cancer cells. A PEM scan may be better able to detect small clusters of cancer cells within the
breast.
• As with MBI, it exposes the whole body to radiation, so it’s unlikely to be a test that could be used
every year for breast cancer screening.
• contrast dye containing iodine is injected into a vein a few minutes before two sets of mammograms
are taken.
• The contrast can help the x-rays show any abnormal areas in the breasts.
• This test can be used to get a better look at areas that appear abnormal on a standard mammogram, or
to help assess the extent of a tumor in women just diagnosed with breast cancer. Studies are now
comparing it to breast MRI in these settings, as well as possibly for use in screening women with dense
breasts.
• If it proves to be as good as MRI, CEM could become more widely used because it is quicker to do and is
less expensive than MRI.
Contrast-enhanced mammography (CEM)
OPTICAL IMAGING TESTS
• pass light into the breast and then measure the light that returns or passes through the tissue. The
technique does not use radiation and does not require breast compression. Studies going on now are
looking at combining optical imaging with other tests like MRI, ultrasound, or 3D mammography to help
look for breast cancer.
• scans the breast for electrical conductivity.
• It’s based on the idea that breast cancer cells conduct electricity differently from normal cells.
• The test passes a very small electrical current through the breast and then detects it on the skin of the
breast.
• This is done using small electrodes that are taped to the skin.
• EIT does not use radiation or compress the breasts.
• This test can be used to help classify tumors found on mammograms.
• But at this time there hasn’t been enough clinical testing to use it for breast cancer screening.
Electrical impedance imaging (EIT)
ELASTOGRAPHY
• It’s based on the idea that breast cancers tend to be firmer and stiffer than the surrounding breast
tissue.
• For this test, the breast is compressed slightly, and the ultrasound can show how firm a suspicious area
is.
• This test might prove to be useful in telling if the area is more likely to be cancer or a benign tumor.

Breast cancer screening

  • 2. WHAT ARE SCREENING TESTS? • Screening refers to tests and exams used to find a disease in people who don’t have any symptoms. • Early detection means finding and diagnosing a disease earlier than if you’d waited for symptoms to start. • Although breast cancer screening cannot prevent breast cancer, it can help find breast cancer early, when it is easier to treat. Early detection is best protection! 
  • 3. Factors to assess risk category: • Age • Genes • Family history • Breast density  The algorithm in which we start screening all relies on the risk category that the individual’s is in
  • 4. • Women aged 40 to 44 years should have the choice to start breast cancer screening once a year with mammography if they wish to do so. (The risks of screening as well as the potential benefits should be considered) • Women aged 45 to 49 years should be screened with mammography annually. • Women aged 50 to 54 years should be screened with mammography annually. • women aged 55 years and older, screening with mammography is recommended once every two years or once a year. • Women aged 75 years or older with average risk should continue screening with mammography as long as their overall health is good and they have a life expectancy of 10 years or more • Women with dense breasts: Evidence is insufficient to recommend for or against yearly MRI screening. Women with average risk
  • 5. WOMEN WITH HIGH RISK OF DEVELOPING BREAST CANCER! Women who are at high risk for breast cancer based on certain factors should get a breast MRI and a mammogram every year, typically starting at age 30. • Have a lifetime risk of breast cancer of about 20% to 25% or greater. • Have a known BRCA1 or BRCA2 gene mutation. • Have a first-degree relative (parent, brother, sister, or child) with a BRCA1 or BRCA2 gene mutation, and have not had genetic testing themselves • Had radiation therapy to the chest when they were between the ages of 10 and 30 years • Have Li-Fraumeni syndrome, Cowden syndrome, or Bannayan-Riley-Ruvalcaba syndrome, or have first-degree relatives with one of these syndromes  Bannayan–Riley–Ruvalcaba syndrome (BRRS) is a rare overgrowth syndrome and hamartomatous disorder with occurrence of multiple subcutaneous lipomas, macrocephaly and hemangiomas. Mutation of the PTEN gene underlies this syndrome, as well as Cowden syndrome, Proteus syndrome, and Proteus-like syndrome, these four syndromes are referred to as PTEN Hamartoma-Tumor Syndromes.
  • 6. MAMMOGRAMS • Mammograms are low-dose x-rays that can help find breast cancer, 2 main types of breast changes found with a mammogram are calcifications and masses. • machine has 2 plates that compress or flatten the breast to spread the tissue apart. This gives a better picture and allows less radiation to be used. • More pictures are taken during a diagnostic mammogram with a focus on the area that looked different on the screening mammogram. • mammogram report will also contain an assessment of your breast density, Dense breasts are not abnormal, but they are linked to a higher risk of breast cancer. Dense breast tissue can also make it harder to find cancers on a mammogram. ( with aging density usually is less, high density calls for using ultrasound). • https://youtu.be/XzAgfCIX2JY
  • 7. MAMMOGRAM POSSIBLE FINDINGS Calcifications: tiny calcium deposits within the breast tissue. They look like small white spots on a mammogram. They may or may not be caused by cancer. There are 2 types of calcifications. • Macrocalcifications: are larger calcium deposits that are most likely due to changes caused by aging of the breast arteries, old injuries, or inflammation, are typically related to non-cancerous conditions and don’t need to be checked for cancer with a biopsy,(more common as women get older). • Microcalcifications: are tiny specks of calcium in the breast, they are more of a concern than macrocalcifications, but they don’t always mean that cancer is present. •  In most cases, microcalcifications don’t need to be checked with a biopsy. But if they have a suspicious look and pattern, a biopsy will be recommended to check for cancer. • Masses: an area of dense breast tissue with a shape and edges that make it look different than the rest of the breast tissue,Masses can be many things, including cysts (non- cancerous, fluid-filled sacs) and non-cancerous solid tumors (such as fibroadenomas), but they may also be a sign of cancer. • A cyst and a solid mass can feel the same, can also look the same on a mammogram, thus the doctor must be sure it’s a cyst or not so a breast ultrasound is made, Another option is to use a needle to aspirate fluid from the area.
  • 8. Breast density in mammograms More of the breast is made of dense glandular and fibrous tissue (described as heterogeneously dense). This can make it hard to see small tumors in or around the dense tissue. Breasts are extremely dense, which makes it hard to see tumors in the tissue. Breasts are almost all fatty tissue. There are scattered areas of dense glandular and fibrous tissue.
  • 9. BI-RADS ASSESSMENT CATEGORY • BI-RADS 0 refers to the need of redoing a new mammogram or even an ultrasound. • BI-RADS 3 refers to the need of an near follow up within 6 months. • BI-RADS 4/5 they needs taking biopsy for conformation. • BI-RADS usually for follow up the effectivity of a treatment given for a breast cancer patient (follow up).
  • 10. BREAST ULTRASOUND • Breast ultrasound uses sound waves to make a computer picture of the inside of the breast. • It can show certain breast changes, like fluid-filled cysts, that are harder to identify on mammograms. • Used in women with dense breast. • Ultrasound is useful because it can often tell the difference between fluid-filled cysts and solid masses. • Ultrasound can also be used to help guide a biopsy. • Ultrasound is widely available, easy to have, and does not expose a person to radiation. It also costs less than a lot of other options. • Automated breast ultrasound (ABUS) is an option that uses a much larger transducer to take hundreds of images that cover nearly the entire breast. When ABUS is done, a second handheld ultrasound is often needed to get more pictures of suspicious areas.
  • 11. Hyperechoic – more echogenic (brighter) than normal Hypoechoic – less echogenic (darker) than normal Isoechoic – the same echogenicity as another tissue Anechoic – The term is usually used in medicine ,when discussing images of body parts that appear black on. https://radiologyassistant.nl/breast /ultrasound/ultrasound-of-the- breast#breast-cancer
  • 12. BREAST MAGNETIC RESONANCE IMAGING (MRI) • A breast MRI uses magnets and radio waves to take pictures of the breast. MRI is used along with mammograms to screen women who are at high risk for getting breast cancer. • breast MRIs may appear abnormal even when there is no cancer, they are not used for women at average risk. • help measure the size of the cancer, look for other tumors in the breast, and to check for tumors in the opposite breast. • not every woman who has been diagnosed with breast cancer needs a breast MRI. • screening MRI is recommended along with a yearly mammogram. • Before the test, you need to have a contrast solution (dye) injected into your arm through an intravenous line • MRI is not a replacement for mammography • https://www.youtube.com/watch?v=S16eUPbZ1Zo
  • 13. CT-SCAN + PET • is an X-ray technique that gives doctors information about the body’s internal organs in 2-dimensional slices, or cross-sections. • Before the test, you need to have a contrast solution (dye) injected into your arm through an intravenous line • CT scans are not used routinely to evaluate the breast • CT scans to examine other parts of the body where breast cancer can spread, such as the lymph nodes, lungs, liver, brain, spine. • CT scans is used during treatment to see whether or not the cancer is responding. • positron emission tomography: a form of radioactive sugar (called FDG) is put into a vein and travels throughout the body. Cancer cells absorb high amounts of this sugar. A special camera then takes pictures that show the areas where the sugar collected throughout the body. A PET scan is often combined with a CT scan (known as a PET/CT scan)
  • 14. NEWER AND EXPERIMENTAL BREAST IMAGING TESTS • Molecular breast imaging (MBI) • Positron emission mammography (PEM) • Contrast-enhanced mammography (CEM) • Optical imaging tests • Electrical impedance imaging (EIT) • Elastography
  • 15. MOLECULAR BREAST IMAGING (MBI) • is a type of nuclear medicine imagining test for the breast. • A radioactive chemical is injected into the blood, and a special camera is used to see into the breast. This test is being studied mainly as a way to follow up breast problems (such as a lump or an abnormal mammogram), or to help determine the extent of breast cancer that has already been diagnosed. • It’s also being studied as a test that can be used along with mammograms to look for cancer in women with dense breast. • Due to exposing the whole body to radiation, so it’s unlikely this test would be used for screening every year.
  • 16. POSITRON EMISSION MAMMOGRAPHY (PEM) • is very similar to a PET SCAN, A form of sugar attached to a radioactive particle is injected into the blood to detect cancer cells. A PEM scan may be better able to detect small clusters of cancer cells within the breast. • As with MBI, it exposes the whole body to radiation, so it’s unlikely to be a test that could be used every year for breast cancer screening. • contrast dye containing iodine is injected into a vein a few minutes before two sets of mammograms are taken. • The contrast can help the x-rays show any abnormal areas in the breasts. • This test can be used to get a better look at areas that appear abnormal on a standard mammogram, or to help assess the extent of a tumor in women just diagnosed with breast cancer. Studies are now comparing it to breast MRI in these settings, as well as possibly for use in screening women with dense breasts. • If it proves to be as good as MRI, CEM could become more widely used because it is quicker to do and is less expensive than MRI. Contrast-enhanced mammography (CEM)
  • 17. OPTICAL IMAGING TESTS • pass light into the breast and then measure the light that returns or passes through the tissue. The technique does not use radiation and does not require breast compression. Studies going on now are looking at combining optical imaging with other tests like MRI, ultrasound, or 3D mammography to help look for breast cancer. • scans the breast for electrical conductivity. • It’s based on the idea that breast cancer cells conduct electricity differently from normal cells. • The test passes a very small electrical current through the breast and then detects it on the skin of the breast. • This is done using small electrodes that are taped to the skin. • EIT does not use radiation or compress the breasts. • This test can be used to help classify tumors found on mammograms. • But at this time there hasn’t been enough clinical testing to use it for breast cancer screening. Electrical impedance imaging (EIT)
  • 18. ELASTOGRAPHY • It’s based on the idea that breast cancers tend to be firmer and stiffer than the surrounding breast tissue. • For this test, the breast is compressed slightly, and the ultrasound can show how firm a suspicious area is. • This test might prove to be useful in telling if the area is more likely to be cancer or a benign tumor.
