We compared the health-related quality of life, impact of the disease, risk perception of recurrence and dying of breast cancer, and understanding of diagnosis of patients with ductal carcinoma in situ (DCIS) and invasive breast cancer 2-3 years after treatment. We included all women (N = 211) diagnosed with DCIS or invasive breast cancer TNM stage I (T1, N0, and M0) in three community hospitals in the southern part of The Netherlands in the period 2002-2003. After verifying the medical files, 180 disease free patients proved eligible for study entry, 47 of whom had DCIS and 133 stage I invasive breast cancer. one-hundred and thirty-five patients returned a completed questionnaire (75% response). No significant differences were found between women with DCIS and invasive breast cancer on the physical and mental component scale of the RAND SF-36, nor on the WHO-5, which assesses well-being. In contrast, women with DCIS reportedly had a better physical health, better sex life and better relationships with friends/acquaintances than women with invasive breast cancer. Despite their better prognosis, the DCIS-group had comparable perceptions of the risk of recurrence and dying of breast cancer as women with invasive breast cancer. However, this did not appear to affect their well-being significantly.
