Chemotherapy
Chemotherapy is the use of drugs to kill cancer cells.
What is chemotherapy?
Chemotherapy uses drugs to kill cancer cells. Chemotherapy is used to:
- Help cure some cancers
- Shrink a cancer before surgery, to make it easier to remove
- Kill any cancer cells that remain after surgery
- Help radiotherapy to work better
- Help stop cancer from spreading, slow its growth, or destroy cancer cells that have spread to other parts of your body
- Treat cancer that has come back after treatment
How does chemotherapy work?
Chemotherapy drugs affect how a cancer cell divides and grows. Chemotherapy damages genes inside the cancer cell, preventing them from growing. Chemotherapy affects healthy cells too, but cancer cells are more sensitive to chemotherapy because they divide more frequently.
Healthy cells usually repair the damage caused by chemotherapy but cancer cells cannot and so they eventually die.
Before you begin chemotherapy
- Ask about possible side-effects.
- Check if you need to do anything to prepare for treatment. For example, getting dental work done or having any recommended.
- Join our chemotherapy education programmes for people who are due to begin chemotherapy. Details below.
Drugs used in chemotherapy
There are many types of chemotherapy drugs that can be given individually or in combination.
These combinations used by your doctor are often known by a word made up from the first letters of the drug names. For example the combination of cyclophosphamide, epirubicin and fluorouracil is called 'CEF'.
If you know the name of your chemotherapy drug, visit the Health Products Regulatory Authority’s website where you will find more information about:
- What the drug is
- How it is given
- Possible side-effects
How is chemotherapy given?
Chemotherapy is usually given in a course of treatments. A treatment course often takes between 3 to 6 months, but it can be more or less than that.
A course is made up of cycles. A cycle is the day or days of your treatment, followed by a rest period, when you have no treatment and your body is recovering. Your cancer doctor will explain the number of cycles you need to treat the cancer. It will depend on your type of cancer and the drug or drugs you are receiving.
Usually you will not need to stay in hospital overnight if you’re having chemotherapy, but for some treatments you will need to stay in hospital.
Chemotherapy is given in different ways, depending on the cancer type and the drugs being used. It may be given to you through:
- A drip (intravenous infusion) into the bloodstream through a vein – drugs are diluted in a large bag of liquid and go in slowly over several hours.
- An injection into the bloodstream (usually through a vein). The drugs are injected into a drip by a nurse. It can last from a few minutes to 20 minutes.
- Tablets or capsules taken by mouth (oral therapies). Read more about oral therapies
- By injection into the fluid around the spine and brain (intrathecal chemotherapy)
- Directly into an organ, such as the liver
- Directly into a body cavity, e.g., the bladder (intracavity chemotherapy)
- Applied as a cream to the skin (topical chemotherapy)
- By injection into a muscle (intramuscular chemotherapy)
- Under the skin (subcutaneous chemotherapy)
Chemoradiation
Taking certain chemotherapy drugs can make the cancer cells more sensitive to radiation (radiosensitisers). This helps the radiotherapy to work better. Having chemotherapy and radiotherapy together is called chemoradiation.
Side-effects
Different chemotherapy drugs can cause different side-effects. Your doctor and specialist nurse will talk to you about the drugs you’ll be having and possible side-effects.
Always tell your doctor or nurse about any side-effects you have. Your doctor can give you drugs to help control some side-effects. After your treatment is over, most side-effects start to improve.
You may find it helpful to keep a record of your side-effects. This can help you talk to your doctors and nurses and find the best way to manage them.
