What is chemotherapy?
The word ‘chemotherapy’ simply means ‘drug treatment’. Chemotherapy uses cytotoxic (anti-cancer) drugs which enter the blood system to destroy cancer cells. A chemotherapy drug can be given either on its own or in combination with other drugs. When more than one drug is given, it is known as a combination chemotherapy regimen. There are over 200 types of cancer and, in the UK, more than 50 chemotherapy drugs are currently licensed. Your consultant will advise you on what chemotherapy drug or combination is right for you.
How does chemotherapy work?
Chemotherapy drugs work by interfering with the ability of cells to divide and grow. The affected cells become damaged and eventually die. As the drugs are carried in the blood, they can reach cancer cells all over the body. Unfortunately, chemotherapy drugs can also affect normal cells, sometimes causing side effects. Unlike cancer cells, normal cells quickly recover, so any damage to them is usually temporary and most side effects will disappear once the treatment is over. Your consultant will discuss the possible side effects with you before you start your treatment.
What is the aim of chemotherapy?
You can be given chemotherapy for different reasons. You may be given ‘curative’ chemotherapy to try and cure the cancer. Chemotherapy may be used if cancer has spread or there’s a risk it will. It may also be used to reduce the risk of cancer coming back after treatment or surgery. Sometimes chemotherapy is used in combination with other treatments such as radiotherapy to make them more effective. In some cases, when the cancer cannot be cured, chemotherapy is used to relieve symptoms, this is known as palliative chemotherapy.
How will I receive my chemotherapy?
Chemotherapy can be delivered intravenously (into the blood stream) or orally via tablet form. The way your chemotherapy is delivered will depend on the drug you are prescribed.
If your chemotherapy is delivered intravenously a small needle will be inserted into your hand or arm for the chemotherapy to be delivered through. You will normally need to stay in the chemotherapy lounge whilst it is being administered.
If your chemotherapy is delivered orally via a tablet you will be given a supply of tablets along with instructions about when and how to take them by your chemotherapy nurses.
How long will my chemotherapy treatment take?
The length of your chemotherapy treatment will depend on your type of cancer. Your consultant will discuss with you how long your treatment course will take.
If you are receiving chemotherapy delivered intravenously this may take several hours. Your chemotherapy nurses will be able to explain how long the procedure will take.
