Mucinous carcinoma in an octogenarian: Treatment and management of breast cancer in the elderly

Age is a risk factor for breast cancer in females, and over 60% of female breast cancer deaths occur in those aged 65 and older. As the population in the United States continues to age, it is expected that there will be a commensurate increase in the number of women diagnosed with breast cancer, making understanding of effective treatment and management of breast cancer in the elderly essential. Here, we review the treatment and management of early breast cancer in the elderly. We report a case of invasive mucinous carcinoma in an 80-year-old female detected on routine clinical breast exam by her primary care physician. Mucinous carcinoma of the breast is a type of rare invasive neoplasm that generally carries an excellent prognosis. Following an ultrasound-guided core needle biopsy, a right breast needle localized segmental mastectomy was performed and the patient was prescribed an aromatase inhibitor for hormone-receptor positive tumor. After a follow-up of 8 years, the patient remains free of recurrence or metastasis and vibrantly living meaningful daily life.
