Bengaluru, Nov 10: A breast cancer diagnosis can bring several difficult decisions for women, particularly those who hope to become mothers in the future. While treatment and recovery remain the immediate priorities, concerns about fertility and the possibility of pregnancy after cancer treatment are also important considerations.
However, a breast cancer diagnosis does not automatically mean the end of a woman's chances of motherhood. The impact on fertility depends on several factors, including the woman's age, type of cancer and treatment involved.
Dr Mangala Devi KR, Consultant – Obstetrics and Gynaecology at Manipal Hospital, Old Airport Road, said breast cancer itself does not directly damage the ovaries or reproductive organs, but certain treatments can affect reproductive health and reduce the chances of natural conception.
"Breast cancer does not necessarily mean the end of a woman’s reproductive journey," she explained.
Chemotherapy can damage ovarian follicles, which contain immature eggs. Depending on the medicines used and the woman's age, this may reduce ovarian reserve, cause temporary infertility or lead to permanent loss of ovarian function. Some women may also experience premature menopause.
The impact of treatment varies from person to person. Younger women may have a better chance of recovering ovarian function, but age alone cannot determine the outcome.
Hormone therapy also requires careful pregnancy planning. Tamoxifen and aromatase inhibitors, commonly prescribed for hormone-sensitive breast cancers, can affect menstrual cycles. Pregnancy is generally avoided while taking these medicines.
Women who wish to have children in the future are advised to discuss fertility preservation before starting chemotherapy, wherever possible.
Available options include egg freezing, in which unfertilised eggs are retrieved and stored for future use, and embryo freezing, where retrieved eggs are fertilised with sperm before the resulting embryos are frozen. Ovarian tissue freezing, which involves removing and storing a portion of ovarian tissue for potential future use, may also be considered in selected cases.
Women with hormone-sensitive breast cancer may undergo specialised ovarian stimulation protocols using medicines such as letrozole to limit estrogen exposure during the fertility preservation process.
Pregnancy may still be possible after breast cancer treatment. However, the appropriate time depends on the cancer diagnosis, treatment received, risk of recurrence and the woman's reproductive health.
Women undergoing long-term hormone therapy should discuss their pregnancy plans well in advance. In selected cases, doctors may consider temporarily interrupting treatment under close medical supervision.
Stopping medication independently can compromise cancer treatment and should never be considered an option, doctors caution.
One of the major challenges is that fertility discussions sometimes take place only after treatment decisions have already been made. Early counselling can help women understand the available options and make informed decisions before starting cancer treatment.
"Fertility preservation is about more than freezing eggs or embryos. It is about preserving choice, supporting quality of life and helping women make informed decisions about their future," Dr Mangala Devi said.
An early discussion involving an oncologist and fertility specialist can help women explore their options without unnecessarily delaying cancer treatment. The objective is not to guarantee motherhood, but to ensure that the possibility of having children in the future is not overlooked.
