Surgery during your period | CION Cancer Clinics
Yes, for most operations it is fine to have surgery during your period. It does not make you bleed more from the cut or stop the anaesthetic working. Tell the admitting nurse, wear a pad rather than a tampon or cup, and mention any hormone tablets. A few operations on the womb or cervix may be timed around your cycle, so ask your surgeon early. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
Is it okay to have surgery during your period?
Yes, for most operations. Having your period is not usually a reason to postpone cancer surgery. Tell the nurse on admission, and the team will plan around it quietly.
Why it rarely changes anything
The bleeding from a period is a normal, expected amount. It does not make you bleed more from the surgical cut. It does not stop the anaesthetic from working. Theatre staff look after women on their period every day, and nothing about it will surprise them.
Why you should still say so
The team needs to know for practical reasons. They will ask you to wear a pad rather than a tampon or a menstrual cup. They will expect some blood when they place a urine tube, called a catheter, and will not mistake it for a problem. And if the date of your last period is unclear, a pregnancy test on admission becomes more important.
What this page cannot tell you
A few operations, mostly on the womb, the cervix or the vagina, may be timed around your cycle. This page cannot tell you whether yours is one of them. Ask your surgeon directly when the date is being set, not on the morning itself.
There is nothing to feel embarrassed about. Saying it once, early, saves you worrying about it all day.The practical part
What will the team actually ask you to do?
None of this is complicated. It helps to know it before you reach the ward.
Use a pad, not a tampon or cup
You may be asleep for hours and cannot change a tampon or cup during that time. Left in too long, a tampon carries a small risk of a serious infection. A pad can be checked and changed by the nurse.
Tell the admitting nurse
Mention it when your details are taken, along with the date your period started. It is written in your notes so everyone in theatre knows.
Also mention
- Very heavy periods or clots
- Any chance you could be pregnant
Pack a few extra things
Carry more pads than you think you need, a few pairs of dark cotton underwear and a small bag for used pads. Some hospitals give disposable underwear for theatre.
Ask for a woman nurse if you prefer
You can ask for a woman nurse to help you change or to check your pad. Hospitals try to arrange this. Saying so early makes it easier.
Not sure whether this applies to you?
Ask an oncologistOn the day
What happens with your period from ward to recovery?
On the ward
You change into a hospital gown and a fresh pad. The nurse asks the date of your last period and may take a urine sample for a pregnancy test. This is routine for women who could become pregnant.
In theatre
Staff are told before you arrive. Once you are asleep they may place a catheter and a clean pad. Your privacy is kept, and you stay covered apart from the area being operated on.
In recovery
When you wake up, the nurse checks your pad along with your wound and drips. Tell them if the bleeding seems much heavier than your usual period, or if you feel faint.
Back on the ward
Ask for help to change until you can get up safely. Stress and anaesthesia can make a period arrive early, late or heavier than usual for a month or so.
When it does matter
When might the team plan around your cycle?
Only in a few situations. In each of them, the decision belongs to your surgeon and anaesthetist, and they will explain their reasons.
Very heavy bleeding or a low haemoglobin
Some women with cancer already have low haemoglobin, the part of the blood that carries oxygen. Heavy periods can lower it further. If your blood test shows this, the team may treat it first or arrange blood, whatever the day of your cycle.
Operations or examinations on the womb and cervix
A surgeon examining or operating inside the womb, cervix or vagina may prefer you are not bleeding heavily, because blood can make it harder to see. Your gynaecological oncologist will tell you if the date needs to fit your cycle.
Tablets to delay a period or for hormones
Many families use tablets to delay a period for a function or a pilgrimage. Hormone tablets, including the contraceptive pill, can raise the risk of blood clots after surgery. Tell the team about any you take or plan to take. Do not start or stop them on your own. The team decides what is safe and when.
Leave a number, we will call you
One field. No form to fill in, and no charge for the call.
On your forms
What do the words on the admission form mean?
- LMP
- Last menstrual period. The date your most recent period started. The nurse will ask for it, so keep it noted on your phone.
- Urine pregnancy test
- A simple test on a urine sample. It is done before many operations for any woman who could be pregnant, and is not a comment on you.
- Catheter
- A thin, soft tube placed in the bladder to drain urine during and after a longer operation. It is usually placed after you are asleep.
- Haemoglobin
- The part of the blood that carries oxygen. A low figure may need treatment before surgery, whatever the cause.
- Clot risk assessment
- A check of how likely you are to form blood clots in the legs after surgery. Hormone tablets are one of the things it asks about.
Commonly believed
What do women and families often believe about this?
"You will bleed much more in the operation if you are on your period."
Bleeding during surgery depends on the operation and on how your blood clots, not on the period itself. If you have a bleeding problem or take blood thinners, that matters far more. Tell the team about both.
"The anaesthetic does not work properly during a period."
There is no good reason to believe this. The anaesthetist sets the medicines by your weight, health and the length of the operation, and watches you closely throughout.
"A woman on her period should not go into the operating theatre."
This is a family or religious belief, not a medical rule. Hospitals operate on women during their period every day. If it weighs on you, talk to the team rather than quietly moving the date.
"A tablet to push the period back is harmless before surgery."
Some of these are hormone tablets, which can raise the risk of clots in the legs after an operation. Ask the surgical team before taking one, even if you have used them before.
Did you know
Chemotherapy or hormone treatment before surgery can make periods irregular, lighter or stop for a while. Tell the nurse if yours have changed. A stopped period does not always mean you cannot become pregnant, which is why the pregnancy test is still done.
Questions we are asked
Common questions about surgery during your period
Will my surgery be cancelled if my period starts?
Usually not. For most cancer operations a period is not a reason to change the date. Tell the nurse when you are admitted so it is noted. If your operation is on the womb, cervix or vagina, ask your surgeon in advance whether they would prefer a different day.
Can I wear a tampon or menstrual cup into surgery?
No. You will be asked to remove it and wear a pad instead. You cannot change a tampon or cup while you are asleep, and one left in too long carries a small risk of a serious infection. A pad lets the nurse check your bleeding easily.
Can I keep my underwear on during the operation?
It depends on the operation. For surgery well away from the pelvis, some hospitals let you keep underwear and a pad on. Others give disposable underwear. For abdominal or pelvic operations it is usually removed after you are asleep. Ask the ward nurse what applies to you.
Why do they want a pregnancy test when I am on my period?
Some bleeding in early pregnancy can look like a period, and anaesthesia, scans and some medicines need extra care in pregnancy. The test is a simple urine check done for any woman who could be pregnant. It is routine and says nothing about you.
I take tablets for heavy periods. Should I stop them?
Do not stop or change them on your own. Some tablets for heavy periods affect how blood clots, and some contain hormones. Bring the strips to your fitness check and tell the anaesthetist. They and your surgeon decide whether to continue, pause or switch, and when.
Will the operation make my next period strange?
It can. The stress of surgery, anaesthesia and time in bed can make the next period come early or late, or be heavier or lighter. This usually settles. Tell your doctor if you bleed very heavily, feel faint, or your periods stay unusual for several months.
My mother feels ashamed to tell a male doctor. What can we do?
She can tell a woman nurse instead, and the nurse will note it in her file. A family member can also mention it at the admission desk. The team only needs the information recorded. She does not have to discuss it with anyone she is uncomfortable with.
Is surgery during a period more painful?
The operation itself is not more painful, because you are asleep or numbed. Period cramps may still be there when you wake up. Tell the nurse about them along with your wound pain, so the pain relief you are given covers both.
