Women with disabilities are one-third more likely to die from their breast cancer than women without disabilities

Why the Disparity?

 After surgery for breast cancer, women with disabilities are less likely to receive: 1

– Radiotherapy

– Axillary lymph node dissection

 They are also less likely to receive:

– Screening mammograms 2

Does lack of exercise play a role?

Coming to Terms

What does disability mean?

Americans with Disabilities Act

A Person Has a Disability if He or She:

 Has a physical or mental impairment that substantially limits one or more of the major life activities of such individual;

 Has a record of such an impairment; or

 Is regarded as having such an impairment 1

1. Americans with Disabilities Act of 1990.

U.S. Surgeon General’s “Call to Action to

Improve the Health and Wellness of Persons with Disabilities”

Disabilities Are…

“…characteristics of the body, mind, or senses that, to a greater or lesser extent, affect a person’s ability to engage independently in some or all aspects of day-today life.”

Disabilities Are Not Illnesses.

“Just as health and illness exist along a continuum, so, too, does disability. Just as the same illnesses can vary in intensity from person to person, so, too, can the same condition lead to greater or lesser limitation in activity from one person to another.”1

1. Office of the Surgeon General. Surgeon General’s Call to Action to Improve the Health and Wellness of Persons with Disabilities . 2005.

Risk Factors

Relative Risk Factors for

Breast Cancer

 Increasing age

 Family history of breast cancer in first-degree relative

 BRCA gene mutations

 Early menarche, late menopause

 Nulliparity or > 35 years old at birth of first child

 No history of breast-feeding

 Personal history of breast cancer or certain noncancerous breast diseases/conditions, including higher breast density

 Being overweight

 Not getting regular exercise

 Long-term use of hormone replacement therapy

 Use of oral contraceptives

 Alcohol consumption (more than one drink a day)

 Treatment-dose radiation to the breast/chest

Factors That Put Women at High Risk

 A BRCA gene mutation

 A very strong family history of breast cancer, such as a mother or sister who was diagnosed with breast cancer at age 40 or younger

 A personal history of breast cancer, LCIS, or atypical hyperplasia

 Past exposure to treatment-dose ionizing radiation during childhood or young adulthood

Risk-Reduction Strategies for

Women with Disabilities

All women should have a breast cancer risk assessment and be offered appropriate risk-management strategies

Identifying High-Risk Women

Encourages Women to:

 Have more rigorous screening

 Be counseled about preventive therapies

Assessment Tools:

Epidemiologic risk-assessment models (e.g., Gail model)

 Genetic testing

The Modified Gail Model

Risk Factors Used In Calculation: 1

 Current age

 Age at menarche

 Age at first live birth or nulliparity

 Number of first-degree relatives with breast cancer

 Number of previous benign breast biopsies

 Atypical hyperplasia in a previous breast biopsy

 Race

1. National Comprehensive Cancer Network (NCCN). Risk factors used in the modified Gail Model; 2007.

The Modified Gail Model

5-year Gail risk < 1.66% = low risk

5-year Gail risk > 1.66% = high risk

NCI’s Breast Cancer Risk

Assessment Tool: www.cancer.gov/bcrisktool

Genetic Testing

 May predict risk more accurately than family history alone 1

 5% –10% of women who develop breast cancer have BRCA gene mutations 1

 Women with BRCA mutations have lifetime risk of 1

– Up to 85% for breast cancer

– Up to 60% for ovarian cancer

 BRCA carriers at highest risk have family history of 2

– Breast cancer diagnosis ≤ age 35

– Contralateral breast cancer

Clinical Options for Managing

Women at High Risk

 Increased surveillance

– Clinical breast exam

– Mammography

– MRI

 Chemoprevention

– Tamoxifen

– Raloxifene

 Prophylactic surgery

Tamoxifen and Raloxifene: Assessing

Risks for Women with Disabilities

 Increased risk of stroke and thromoboembolic events

(women with limited mobility already at risk) 1

 Increased risk of uterine cancer 1

 Other risks: 2

– Cataracts and other eye problems

– Bladder problems

– Vaginal problems

1. Vogel VG, et al., for the National Surgical Adjuvant Breast and Bowel Project (NSABP). JAMA.

2006;295:2727-2741.

2. National Cancer Institute. Reviewed May 13, 2002. Available at www.cancer.gov/cancertopics/factsheet/Therapy/tamoxifen.

Managing Women with Disabilities on Tamoxifen and Raloxifene

 Assess patient’s individual risk for thromoboembolism

 Advise and assist patient with:

– Quitting smoking

– Lowering blood pressure

– Maintaining a healthy weight

– Exercising regularly

 Follow patient closely

Prophylactic Breast Surgery: Assessing

Risks for Women with Disabilities

 Reduces breast cancer risk by 90% in high-risk women 1

 Most high-risk women report satisfaction with decision to have the surgery 2

 Patient satisfaction is more variable regarding cosmetic results and body image 2

Special concern for women with disabilities:

How will the surgery affect my mobility and quality of life?

1. Hartmann L, et al. N Engl J Med . 1999;340:77-84.

2. Lostumbo L, et al. Cochrane Database of Systematic Reviews . 2004;4:CD002748.

Managing Women with Disabilities

Who Chose Prophylactic Surgery

 Discuss with patient how surgery will affect her adaptive and assistive needs

 Make sure patient has sufficient home care after surgery

 Start physical therapy before surgery

 Postsurgical physical therapy essential for restoring function and quality of life

Modifiable Risk Factors

 Being overweight

– Women overweight at age 50:

50% increase in risk 1

 Not getting enough exercise

– 1.25–2.5 hours of brisk walking:

18% decrease in risk 2

 Consuming alcohol daily

– Each 10 g of daily alcohol: 7.2% increase in risk 3

3.Chen WY, et al. Ann Intern Med . 2002;137:798-804.

Women with disabilities often have more difficulty altering modifiable risk factors

Barriers to Increasing

Physical Activities

 Lack of transportation

 Lack of money

 Lack of time

 Inaccessible fitness centers

 Healthcare and fitness professionals who are inexperienced with working with people with disabilities

 Lack of social support

 Fatigue and pain

Barriers to Increasing

Physical Activities

Lack of self-knowledge about capabilities for exercise and/or skills needed to engage in physical activity

 Equip your facility with a weight scale that accommodates wheelchairs

 Refer patients with disabilities to a dietician with experience addressing their unique dietary and exercise issues

National Center on

Physical Activity and

Disability (NCPAD)

www.ncpad.org

Alcohol Use Among Women with Disabilities

 Alcohol use is as prevalent among women with disabilities as among the general female population 1

 Discuss alcohol use and its breast cancer risk with all patients

 Patients at high risk of breast cancer must carefully weigh risks and benefits of moderate alcohol use

1. Li L, Ford JA. Applied Behavioral Sci Rev.

1996;4:99-109.

Summary

 Women with disabilities have same breast cancer risk as other women, but are one-third more likely to die from the disease

 Reasons for this disparity in survival are unknown, but women with disabilities are less likely to undergo standard chemo and/or radiation therapy after breast-conserving surgery and are less likely to have regular screening mammograms

 All women with disabilities should be assessed for their breast cancer risk and offered risk-reduction strategies

 Risk-reduction strategies raise special issues for women with disabilities that need a thorough clinician-patient discussion

 Helping women with disabilities alter modifiable risk factors and adopt a more healthful lifestyle may require special tools and strategies
