Summary
Brief summary (as posted)
The increased likelihood of survival can be explained by numerous factors, such as improvements in breast cancer screening and advances in diagnosis and treatment and aging. This phenomenon is associated with comorbidity due to cancer treatment and external factors like aging or lifestyle. Little is known about how these women follow-up their disease, their pattern of use of health resources and their met and unmet needs. Studying the health needs of these women is a cancer-related priority for Cancer Organizations.The project is aimed at: 1) Describing the comorbidities and patterns of use of primary and specialized care in women who have survived a breast cancer for at least five years; 2) Comparing the comorbidities and patterns of use of long time breast cancer survivors with women without a cancer diagnosis; and 3) Estimating the use of resources in long time survivors of breast cancer adjusted for survival-time and comorbidities.
