Medical Guide

What worries most people before a first chemotherapy session is that they do not know what it looks like. They have heard about it for years without ever seeing it, and what they picture is usually harder than what actually happens in the treatment room. In practice the session follows a set order: tests beforehand, a short preparation, a drip given into a vein while the nursing team watches, then home the same day in most cases. In this guide, we explain what happens in a chemotherapy session step by step, how long it takes, and what to expect afterwards.

What is chemotherapy and how does it work in the body?

Chemotherapy is a group of medicines that target rapidly dividing cells, cancer cells above all. It differs from radiotherapy in that it is not aimed at one place. It travels through the blood to the whole body, which is why it is often used when cells may be present beyond the original tumour site.

These medicines are given in more than one way depending on the treatment protocol:

• Infusion into a vein, which is the most common route
• Injection under the skin or into a muscle
• Tablets taken by mouth
• Delivery into a specific body cavity in selected cases

This guide covers chemotherapy in cancer care. The single chemotherapy injection sometimes used for an ectopic or molar pregnancy is a different use of one of these medicines, with a completely different protocol and follow-up.

What is the difference between a dose, a session, and a cycle?

Three words come up constantly in clinic and are easy to confuse:

• The dose: the amount of medicine calculated for you, usually from your weight and height
• The session: one visit in which that dose is given at the hospital
• The cycle: the session plus the rest period that follows it, until the next session

So when a doctor says the protocol is six cycles every 21 days, that means six sessions with three weeks between each one. In some protocols a single cycle contains more than one session, such as a session every week for three weeks followed by a rest week.

What happens before the session? Tests and preparation

The session does not begin the moment you arrive. In most hospitals it is preceded by a short assessment to confirm that your body is ready for the dose and that your test results allow it to be given on schedule.

Usual preparation includes:

• A complete blood count to check white cells, platelets, and haemoglobin
• Liver and kidney function tests
• Weight and height measurement for dose calculation
• A review of your medicines and any symptoms after the previous session
• Extra tests for some protocols, such as an ECG or an echocardiogram

Your doctor may postpone the session by a few days if your white cell count is low. That delay is a deliberate treatment decision to protect you from infection, not a sign that the treatment is failing.

How does a chemotherapy session work step by step?

The session usually follows a fixed order, and you will notice it repeats almost identically every time:

1. 1Checking in and reviewing test results with the treating doctor
2. 2Preparation of the dose in the oncology pharmacy once it is approved
3. 3Insertion of a cannula into a vein, or accessing an implanted port if you have one
4. 4Pre-medication such as anti-sickness medicines, a corticosteroid, and an antihistamine
5. 5Slow infusion of the medicine while nursing staff monitor blood pressure, pulse, and the cannula site
6. 6A saline flush through the vein once the infusion finishes
7. 7Removal of the cannula, discharge instructions, and the date of the next session

During the infusion you sit in a comfortable chair or lie on a bed, and in most centres you can read, listen to something, or talk with the person who came with you. The session is not surgery and needs no anaesthetic, and in most protocols you go home the same day.

How long does a chemotherapy session take?

The duration varies a great deal by medicine and protocol. Some medicines are given over half an hour, some need two or three hours, and some protocols run for six hours or more in a single day.

It helps to plan around the whole day rather than the infusion time alone, because the day also includes:

• Waiting for blood test results
• Pharmacy preparation of the dose after the results are approved
• Pre-medication given before the main drug
• An observation period afterwards, which may run from thirty minutes to an hour

For that reason it is best to set aside a full day for the first session. After that you will know the real rhythm of your own sessions and can plan around it.

Is a chemotherapy session painful?

The infusion itself does not hurt. The only expected pain is the sting of the cannula going in, a brief moment much like any blood test. After that the medicine enters the vein without any sensation of pain for most patients.

There is one sensation you should never ignore: burning, pain, or swelling at the cannula site during the infusion. This can mean the medicine is leaking outside the vein and the infusion needs to be stopped straight away. Tell the nurse at that moment rather than waiting for the session to end.

What is the difference between red and white chemotherapy?

Red and white are not medical categories. They are a common patient description of the colour of the fluid in the syringe. Some medicines are clearly red and some are colourless, and the difference comes from the chemistry of the drug itself rather than from its strength.

What is worth knowing about these labels:

• Colour does not mean one dose is stronger than another
• The protocol is chosen by tumour type and stage, not by the colour of the drug
• Some red medicines can turn urine reddish for a day or two after the session, which is expected

If the colour change lasts longer than that, or comes with pain or burning, it is worth telling your treating team.

What should you expect in your first chemotherapy session?

The first session is usually longer than the ones that follow, because the team is watching how your body responds to the medicine for the first time. The infusion rate may be slower, and the observation period afterwards may be extended.

What helps most on that particular day:

• Bring someone with you to the first session.
• Wear comfortable clothing that is loose at the arms.
• Bring your medicine list and previous reports.
• Ask for a contact number in case symptoms appear after you leave.
• Do not drive yourself home afterwards.

Reassuringly, most people leave the first session feeling it was calmer than they had imagined, and tiredness, if it comes, usually starts a day or two later rather than in the moment.

When do side effects start after the session?

Side effects do not all appear at once, and each has its own rough timing:

• Nausea may begin within hours of the session, and anti-sickness medicines are given to reduce it
• Tiredness most often on the second and third day
• Mouth soreness after several days in some protocols
• White cell counts reaching their lowest point around 7 to 14 days, then recovering
• Hair loss, if it happens, two to three weeks after the first session rather than immediately

How strong these effects are varies from person to person and from protocol to protocol. Mild symptoms do not mean the treatment is weak, and severe ones do not mean it is stronger.

What should you eat and drink before and after the session?

You are not usually asked to fast before a chemotherapy session. A light meal beforehand is generally better, because a completely empty stomach can make nausea worse during the infusion.

Practical advice for the day of the session and the two days after:

• Drink plenty of water before and after the session unless your doctor advises otherwise.
• Split your food into small frequent meals rather than two large ones.
• Avoid very rich or heavily spiced food on the day itself.
• Take your anti-sickness medicines on schedule instead of waiting for nausea to start.
• Tell the team if food tastes different or swallowing becomes difficult.

If you cannot eat or drink for more than a day after the session, contact the hospital rather than waiting for your next appointment.

Why are sessions repeated every week or every 21 days?

The gap between sessions is not empty waiting. It is part of the treatment. The medicine also affects some healthy fast-dividing cells, such as bone marrow, the lining of the mouth, and the digestive tract, and the rest period gives those cells time to recover before the next dose.

The number of sessions and their timing depend on:

• The type and stage of the tumour
• The goal of treatment, whether before surgery, after it, or to control the disease
• How the tumour responds in the assessments done during treatment
• How well the body tolerates the doses, and the test results between sessions

So the number of sessions or their dates may change during the treatment journey. That is a normal adjustment to the plan rather than a setback.

When should you call the hospital immediately after a session?

Some symptoms can wait until the next appointment and some cannot. The most important of all is fever, because a raised temperature after chemotherapy can signal an infection at a time when immunity is low.

Call the hospital straight away if any of these appear:

• A temperature of 38 degrees Celsius or higher, or shivering and chills.
• Repeated vomiting or diarrhoea that stops you drinking fluids.
• Unexplained bleeding or bruising, or bleeding from the nose or gums.
• Shortness of breath, chest pain, or a racing heartbeat.
• Redness, swelling, or pain at the cannula or port site.
• Mouth ulcers that stop you eating or drinking.

In these situations specifically, do not wait until morning or until the next scheduled session. Early treatment here is both easier and safer.

How much does a chemotherapy session cost in Egypt?

Costs vary widely and there is no single figure that fits every patient. They depend on the medicine used, the number of doses, the length of the protocol, the tests and scans needed between sessions, and supportive medicines such as injections to raise immunity.

For that reason it is better to ask about the cost of the full protocol rather than the cost of one session. The second question gives an incomplete picture of what you will actually need over the months of treatment.

How can you prepare for your session calmly?

Anxiety before a first session is normal, and it is usually fear of the unknown more than fear of the procedure itself. After one or two sessions the day becomes familiar, and preparing for it gets much easier.

What you can do now:

• Write your questions down before the appointment instead of relying on memory on the day.
• Ask for the name of the protocol, the expected number of sessions, and how long each one takes.
• Pack a small bag with water, a light snack, and something to occupy you during the infusion.
• Keep the department emergency number saved in your phone.
• Record your symptoms after each session to discuss at the next visit.

If you cannot afford the tests or the treatment, you can contact Ayady 4040 Hospital, which provides cancer treatment free of charge to patients who cannot pay.

Reassurance here does not come from imagining the session. It comes from knowing the steps as they really are.
