Women's experience of breast cancer is complex, affecting all aspects of life during and after treatment. Patients' perspectives about common impairments and functional limitations secondary to breast cancer treatment, including upper extremity motion restriction, lymphedema, fatigue, weight gain, pain, and chemotherapy-induced peripheral neuropathy, are addressed. Women often report being uninformed regarding these side effects and surprised that they do not always disappear after treatment, but remain part of their lives. Breast cancer patients express strong, unmet needs for education, information, and intervention for these side effects. Evidence suggests that rehabilitation and exercise are effective in preventing and managing many physical side effects of breast cancer treatment. Nevertheless, few women are referred to rehabilitation during or after treatment, and fewer receive baseline assessments of impairment and function to facilitate early detection of impairment and functional limitations. The prospective surveillance model of rehabilitation will serve the needs of women with breast cancer by providing education and information about treatment side effects, reducing the incidence and burden of side effects through early identification and treatment, and enhancing access to timely rehabilitation. Integration of exercise as a component of the model benefits patients at every phase of survivorship, by addressing individual concerns about exercise during and after treatment and highlighting the important contribution of exercise to overall health and survival. The prospective surveillance model of rehabilitation can meet the evident and often expressed needs of survivors for information, guidance, and intervention-thus addressing, and potentially improving, overall quality of life for individuals diagnosed with and treated for breast cancer. Women's experience of breast cancer is complex, affecting all aspects of their lives during and after treatment. Although each woman's experience with breast cancer is unique, they share common perspectives related to the physical and functional side effects of breast cancer treatment. Activity limitation, upper extremity motion restriction, lymphedema, fatigue, pain, and chemotherapy-induced peripheral neuropathy (CIPN) are well-documented concerns of breast cancer survivors.1-5 Impairments such as limited range of motion, pain, and fatigue appear to be inter-related, and may have an additive effect. Women note that upper extremity issues, fatigue, pain, depression, and body image disturbance tend to compound each other and impact quality of life.6-9 Less information is available about women's concerns regarding other treatment side effects addressed in this supplement (eg, arthralgias, osteoporosis, and cardiotoxicity). This may be because of lack of awareness of these potential long-term side effects, as research about their prevalence and time course is more recent. Cumulatively, these observations provide strong evidence of an unmet need for cancer patients gene...
