People always feel that the increased levels of estrogen and progesterone during pregnancy will promote breast cancer recurrence and metastasis. However, many studies have shown that after getting breast cancer, even if you get pregnant again, it will not cause breast cancer to relapse and metastasize, which will affect the survival and prognosis.

An article published in the Journal of Clinical Oncology (IF: 24.008), an authoritative oncology journal, showed that after breast cancer treatment, pregnancy is safe and feasible. Pregnancy can even improve the overall survival of breast cancer patients. Increase the risk of recurrence and metastasis of estrogen receptor-positive breast cancer patients.

The team also made a follow-up report in 2017: Through long-term follow-up observation, whether it is estrogen receptor positive or negative, pregnancy will not affect the survival rate of breast cancer patients, and for estrogen receptor negative breast cancer patients In other words, pregnancy can improve their overall survival rate.

The study found that compared with patients who did not get pregnant after breast cancer treatment, patients who gave birth after treatment reduced the risk of death by 44% and the risk of disease recurrence by 27%.

The risk of premature delivery of the fetus will increase by 45%, and the risk of Caesarean section will increase by 14%. It is worth noting that the remaining pregnancy complications and congenital defects of the fetus have not increased significantly.

Therefore, strict contraception is recommended during the 5~10 years of endocrine therapy; after surgery and chemotherapy, it is recommended to get pregnant again after 2~3 years, because after surgery The incidence of recurrence and metastasis is relatively high within three years.

For patients who have fertility needs but are still under treatment, oocyte freezing, embryo freezing, ovarian tissue cryopreservation and transplantation, immature oocyte in vitro maturation preservation and ovarian function inhibition drugs can be considered.

Young breast cancer sisters, don’t be depressed, you can still have the opportunity to be a mother after the treatment is over!
