A cancer diagnosis moves fast but your fertility decisions might need to move faster.
One moment you're living your normal life. The next, you're sitting in a clinic trying to process words like "staging" and "treatment timeline" while your whole world quietly reorganizes itself around a diagnosis.
In the middle of all that, there's a question that almost never gets asked, at least not soon enough...
"What does this mean for my chances of having kids one day?"
It's not that your doctor doesn't care. It's that cancer care is urgent, and fertility can feel like a problem for future-you. But for the roughly 8,000 young Canadians diagnosed with cancer each year, that future question can have a very present deadline, one that closes the moment treatment begins.
Why Treatment Can Affect Your Fertility
Chemo, radiation and surgery don't just target cancer cells. Depending on the type and dosage, they can affect your reproductive system too (temporarily or permanently).
Certain chemotherapy drugs (especially a group called alkylating agents) are particularly hard on eggs and sperm. Radiation near the pelvis can damage the ovaries, uterus or testes. Some surgeries involve removing reproductive tissue entirely.
It's frustrating but you often won't find out how your fertility was affected until years later, when you're actually trying to conceive.
The Conversation That's Probably Not Happening
According to the Canadian Partnership Against Cancer, fewer than half of cancer patients in their reproductive years have ever talked to their doctor about fertility.
Part of that is on the system, oncology clinics are stretched thin and fertility can feel like a secondary concern. Some providers assume patients aren't thinking about kids or feel awkward bringing it up. But the clinical guidelines from both ASCO and the Canadian Fertility and Andrology Society are pretty clear: this conversation should happen at diagnosis, before treatment starts.
If your oncologist hasn't brought it up, you're allowed to ask!
What Your Options Actually Look Like
The good news is that there are real, proven options and they're more accessible than most people realize.
Egg freezing is one of the most common routes for people with ovaries. You take hormone injections for 10–14 days to stimulate egg production, the eggs are retrieved and frozen, and when you're ready down the road, they can be thawed, fertilized, and transferred.
Embryo freezing is similar, but the eggs are fertilized before freezing. Common if you have a partner.
Sperm banking is fast and straightforward option. A sample is frozen before treatment begins and stored for future use. This can often be done within days.
Ovarian tissue cryopreservation is a newer option where ovarian tissue is removed and frozen before treatment, then reimplanted later. It's especially useful if there isn't time for a full egg retrieval cycle, or for younger patients who haven't gone through puberty yet.
What makes sense for you depends on your type of cancer, your age, and how quickly treatment needs to start. A fertility specialist can help you figure out what's actually possible given your timeline.
Understanding Timing
Egg retrieval takes a few weeks and sperm banking can happen in days. Either way, these decisions need to happen before treatment starts. That's why getting a referral to a fertility specialist early matters so much. Some clinics, including CReATe Fertility in Ontario, hold dedicated slots each week specifically for oncology patients so there's no waiting. If you're in this situation, asking for an urgent referral is completely reasonable.
The Cost Reality
Fertility preservation isn't covered under most provincial health plans in Canada and that's an unfair barrier. That said, many clinics and pharmaceutical companies offer reduced fees for cancer patients, and there are charitable organizations that help cover costs.
Questions to Ask Your Doctor Now
If you or someone close to you has just been diagnosed, here's what to bring up with the oncology team:
- Will this treatment affect my fertility and is that likely to be temporary or permanent?
- Is there time to pursue fertility preservation before treatment starts?
- Can you refer me to a fertility specialist urgently?
- Are there financial assistance programs I should know about?
If You're Already on the Other Side of Treatment
Survivorship is its own complicated chapter. More people are beating cancer than ever before but it comes with questions nobody fully prepares you for, including what starting a family looks like now.
If you didn't get to preserve fertility before treatment, it's still worth talking to a reproductive specialist. Depending on what you went through, natural conception may still be possible or there may be other paths forward worth exploring. Tracking your cycle post-treatment can also give you and your doctor useful information about how your reproductive system has recovered.
