Tamoxifen is a selective oestrogen receptor modulator widely used in breast cancer treatment, with good survival rates. In the study, women who became pregnant after an early breast cancer diagnosis, including those with estrogen receptor (ER)-positive tumors, did not have a higher chance of cancer recurrence and death than those who did not become pregnant. For some women with breast cancer, taking adjuvant tamoxifen (Nolvadex®) for 10 years after primary treatment leads to a greater reduction in breast cancer recurrences and deaths than taking the drug for only 5 years, according to the results of a large international clinical trial.. It appears that tamoxifen does not alter the age of menopause and women may still get pregnant while on tamoxifen. pregnancy after tamoxifen.

In the study, women who became pregnant after an early breast cancer diagnosis, including those with estrogen receptor (ER)-positive tumors, did not have a higher chance of cancer recurrence and death than those who did not become pregnant. Until the results of the POSITIVE trial are out, for patients who are willing to interrupt ET to become pregnant, counselling on the recurrence risk, multidisciplinary decisions and close follow-up are required.
