Adjuvant chemotherapy for breast cancer and cognitive impairment.

ABSTRACT

Complaints of loss of memory and lack of concentration have been reported by long-term survivors of breast cancer. This mild cognitive impairment (MCI), also called "chemobrain" or "chemofog," has been the subject of a number of studies in the last few years. This cognitive impairment, although usually mild, must be studied to define possible risk factors for its development, and for future research into a preventive or therapeutic treatment approach. Long-term survivors of breast cancer must be followed to detect possible treatment sequelae as soon as possible. Since the number of these long-term survivors has increased in the last years, in part because of more active adjuvant treatments, our knowledge about the long-term side effects of these therapies has also grown.
