systemic therapy will be planned by a medical oncologist. This is a cancer
doctor who specializes in drug treatments.
Before you start your systemic therapy, you may need to have some tests. For example:
- Teeth cleaned and checked: systemic therapy may make your mouth dry and sore. It is important to have your mouth and teeth checked before starting treatment.
- Check your heart: some systemic therapy drugs can damage your heart. Your health care team may ask you to get an electrocardiogram to check how well your heart is working.
Systemic therapy can affect your fertility (your ability to get pregnant, stay pregnant or get someone else pregnant). There may be things you can do to protect your fertility. Some of these things need to be done before treatment. If this is important to you, talk to your health care team before you start your treatment.
Having systemic therapy
Most people get systemic therapy in regular intervals called cycles. For example, you may have treatment one day every three weeks. The time between your treatment is a rest period. This allows your body to heal and recover from any side effects.
The entire course of your treatment, from the first treatment to the last, may be a few months or longer.
Your health care team will talk to you about your treatment cycles and course.
You may get systemic therapy in one of four ways:
A needle attached to a tube is put into your vein. The drug treatment travels through the needle into your vein.
If you get treatment this way, we will give you an appointment date and time. A nurse will give you the treatment. The nurse will also talk with you about your treatment and any side effects you may have.
IV treatment can take anywhere from several minutes, to several hours, to a full day. It depends on your treatment.
Some drug treatments are pills that you swallow.
If you get treatment this way, we will give you an appointment date and time to meet with a BC Cancer pharmacist. The pharmacist will explain your treatment, talk about side effects and give you the pills you need.
If you get treatment this way, a nurse, or another
member of your health care team, will give you an injection. This is when a
needle is put into a part of your body, such as your arm, and the drug
treatment is injected.
Some patients may go home with a continuous IV infusion pump. This is a portable pump that is connected by a tube to a needle in your vein. It allows you to have your treatment at home. This way, you do not have to stay at the hospital or clinic. Not all IV drug treatments can be delivered this way.

When having cancer treatment, it is important that you or your partner do not get pregnant.
Cancer treatments, like radiation and systemic therapy (chemotherapy, immunotherapy, hormone or targeted therapy) may damage eggs, an embryo (very early part of pregnancy), a fetus (unborn baby), or sperm.
If you can get pregnant, your healthcare team will offer to do a pregnancy test before treatment starts. This test is done with your agreement.
What could happen if I get pregnant during treatment?
- You may have to consider stopping treatment.
- You may not be able to have certain treatments or tests.
- Some cancer treatments may damage the egg, sperm, or embryo (especially during the first 3 months). The health of the person having the child may also be affected.
- You may have a miscarriage (fetus or embryo dies) or the baby may have damage (the baby's brain or body may be affected).
It is important to prevent pregnancy while you are getting cancer treatment and often for some time after treatment. Talk to your healthcare team about when it's safe to get pregnant after treatment.
If you or your partner can become pregnant, it is important to use effective birth control when having vaginal sex.
Some hormonal birth control (such as the birth control pill, patch or injection) may not work during cancer treatment.
Your healthcare team can talk with you about what types of birth control are safe to use during your treatment. They can also talk about any concerns you have about preventing pregnancy before, during and after your cancer treatment.
No. It is very important to talk with your health care team about your specific treatment and if you have any questions or concerns.
If you are able to get pregnant and think you might be pregnant, your doctor may order a blood test. This blood test will check to see if you are pregnant.
If you think that you could be pregnant any time during your treatment, please tell your health care team right away. They will ask you to do a blood or urine pregnancy test.
Systemic therapy treatments may be in your body fluids. If your partner comes in contact with your bodily fluids containing treatment drugs during sex, they may harm your partner or fetus.
We recommend using barrier devices (condoms, dental dams) throughout your treatment during oral, vaginal or anal sex. You should use these devices for at least 48 hours after your last treatment. This will prevent your partner from being exposed to any medication that may be in your body fluids.
