• When is a mammogram appropriate?• When is an ultrasound appropriate?• What is the difference between a targeted and a
screening ultrasound?• When is an MRI appropriate?• What is the standard screening tool for breast
cancer?• At what age should screening start?• What significance does pain have in reference to
breast cancer symptoms?

Breast Cancer
• Most common cancer in women (except skin cancer)
• 2nd leading cause of cancer death in women (lung cancer 1st)
• In 2007, 211,990 women in U.S. were dx with invasive breast cancer
• 40,110 will die from the disease• There are slightly more than 2 million
women in the US living with breast cancer

Estimated Breast cancer 2009
• Female
• 192,370 new cases• 40,179 deaths
• male
• 1910 new cases• 440 deaths
![Page 6: Breast Problems08](https://reader038.vdocument.in/reader038/viewer/2022102700/548b081db47959bb0a8b46c0/html5/thumbnails/6.jpg)
• Incidence of breast cancer increasing 1% per yr since the 1940’s
• Mortality rate has been decreasing probably due to early detection and better Tx

Impact of mammography
• 40% of cancers are detected by mammography alone
• 10 % are detected by palpation alone

• Survival is related to node status • Node status correlates with tumor size• Of Cancers < 1 cm – 15% are node pos• Of cancers > 1 cm - 30 % are node pos• Mammography detects smaller tumors• (average size palp tumors is 2 cm) • (average size mammo detected tumors
1cm)

Risk Factors
• Gender (75% of women who devel breast cancer have no other risk factor)
• Aging- risk increases with age (18% dx in women in their 40s , 77% of women > 50 when dx)
• Genetic factors –only 5-10% true hereditary breast cancer with BRCA, BRCA 2 or other mutation.(if pos, 35-85% chance of devel breast cancer in lifetime)
![Page 15: Breast Problems08](https://reader038.vdocument.in/reader038/viewer/2022102700/548b081db47959bb0a8b46c0/html5/thumbnails/15.jpg)
Risk factors
• Family history: male relatives with breast cancer count
• Family history of ovarian /breast (2 or more relatives
• Ashkenazi jewish heritage
• Family hx of Cowdens or LI-Fraumeni syndromes
![Page 16: Breast Problems08](https://reader038.vdocument.in/reader038/viewer/2022102700/548b081db47959bb0a8b46c0/html5/thumbnails/16.jpg)
Risk factors
• Personal history breast cancer(3-4 fold increase in devel 2 nd cancer)
• Hx radiation to breast• Previous bx showing atypia• Early menarche, late menopause• DES therapy – slight increased risk• No children or 1st child after 30• Oral contraceptive use –slight increase
![Page 17: Breast Problems08](https://reader038.vdocument.in/reader038/viewer/2022102700/548b081db47959bb0a8b46c0/html5/thumbnails/17.jpg)
Risk factors
• Race –white slightly more likely to devel cancer than black, but black more likely to die from cancer (more likely to be dx at later stage)
• Hormone replacement tx
• Alcohol –increased risk
• Obesity –increased
• Physical activity decreases risk
![Page 18: Breast Problems08](https://reader038.vdocument.in/reader038/viewer/2022102700/548b081db47959bb0a8b46c0/html5/thumbnails/18.jpg)
? Risk factors
• Environmental
• antiperspirants
![Page 19: Breast Problems08](https://reader038.vdocument.in/reader038/viewer/2022102700/548b081db47959bb0a8b46c0/html5/thumbnails/19.jpg)
No assoc increased risk
• Underwire bras
• Smoking
• Induced abortion
• Breast implants
• Night work

Protective effect
• Long island breast cancer study- women who take aspirin daily have a 30% reduction in breast cancer risk for hormone receptor positive tumors only (these have a better prognosis)
• Finding by questionaire• Aspirin reduces Aromatase production which
suppresses estrogen production• Acetominophen and ibuprophen had no effect• American Medical Association (Vol. 291, No. 20:• 2433-2489)

Workup of breast problems
• Asymptomatic vs symptomatic
![Page 22: Breast Problems08](https://reader038.vdocument.in/reader038/viewer/2022102700/548b081db47959bb0a8b46c0/html5/thumbnails/22.jpg)
Screening
• How often should women be screened
• What to do in high risk patients
• Patients with a hx of breast cancer
![Page 23: Breast Problems08](https://reader038.vdocument.in/reader038/viewer/2022102700/548b081db47959bb0a8b46c0/html5/thumbnails/23.jpg)
Asymptomatic women (screening)
• American cancer society guidelines:
• Yearly mammography starting at age 40 for as long as the woman is in good health
![Page 24: Breast Problems08](https://reader038.vdocument.in/reader038/viewer/2022102700/548b081db47959bb0a8b46c0/html5/thumbnails/24.jpg)
< 40 and no family history
• Screening not recommended

< 40 and mother or sister with premenopausal breast cancer
• Begin screening with mammography and ? Ultrasound/MRI 5 -10 years prior to dx of relative
![Page 26: Breast Problems08](https://reader038.vdocument.in/reader038/viewer/2022102700/548b081db47959bb0a8b46c0/html5/thumbnails/26.jpg)
• In 2003 only 70 % of women in the U.S. reported having had a mammogram in the last 2 years.
![Page 27: Breast Problems08](https://reader038.vdocument.in/reader038/viewer/2022102700/548b081db47959bb0a8b46c0/html5/thumbnails/27.jpg)

Screening ultrasound
• At this time, screening ultrasound is not recommended
• Ongoing ACR trial – multiinstitutional involving women at high risk for breast cancer (mostly patients with personal history of breast cancer)
![Page 54: Breast Problems08](https://reader038.vdocument.in/reader038/viewer/2022102700/548b081db47959bb0a8b46c0/html5/thumbnails/54.jpg)
ACRIN 6666 ultrasound trial
• 2007 – preliminary results
• Use of us would increase detection yield by 4.2 per 1000 women screened, regardless of breast density
• Downside –increase in number of biopsies performed
![Page 55: Breast Problems08](https://reader038.vdocument.in/reader038/viewer/2022102700/548b081db47959bb0a8b46c0/html5/thumbnails/55.jpg)

Screening MRI
• ACS guidelines- in addition to mammography
• BRCA1 or BRCA2
• Lifetime risk of breast cancer 20% or higher

MRI
• Expensive

• Many false positive

Breast development
• Begins during adolescence
• surge of estrogen responsible for devel of ducts
• progesterone necessary for devel of lobules
![Page 64: Breast Problems08](https://reader038.vdocument.in/reader038/viewer/2022102700/548b081db47959bb0a8b46c0/html5/thumbnails/64.jpg)
• Palpable breast masses are uncommon is children
• most masses have a benign etiology
• surgery can arrest breast development

Causes of palp masses in children
• Breast bud• cyst• fibroadenoma• phylloides• lymph node• galactocoele• duct ectasia• abscess• gynecomastia
• Primary breast cancer rare(<.2% cancers in pts <20)
• metastatic disease– late finding– rhabdomyosarcoma– leukemia– lymphoma
