A 45-year-old woman with oestrogen-receptor positive breast cancer is prescribed tamoxifen 20 mg daily after a total mastectomy. What is the most appropriate counselling point for this patient?

• A. Tamoxifen should be taken daily to reduce the risk of the cancer returning
• B. Tamoxifen is best taken with a large meal to improve absorption
• C. Tamoxifen cures breast cancer with a short course
• D. Tamoxifen should be stopped if hot flushes occur

Answer: (A)

Tamoxifen is given as ongoing adjuvant therapy to block estrogen’s effect on any remaining breast cancer cells. Taking it daily helps reduce the risk of recurrence after surgery and can improve long-term outcomes in estrogen-receptor–positive disease. The benefit builds up over months to years, so the emphasis for a patient is consistent, long-term adherence rather than a short course. It isn’t a cure delivered in a brief treatment period, and there’s no requirement to take it with a large meal. Hot flushes can occur, but this doesn’t mean the drug should be stopped; if side effects become troublesome, they can be managed while continuing therapy.
