What is Radiotherapy?

Radiotherapy is the use of high energy x-rays (called ionising radiation) to treat cancer. Radiotherapy is delivered using a machine called a linear accelerator (LINAC) that directs the radiation beam to treat cancer cells while minimising damage to surrounding tissue.

What cancers do Radiotherapy treat?

External beam radiation therapy is used to treat most types of cancer, including the following:

Head & Neck
Larynx
Lung
Cervix
Bladder
Prostate
Vagina
Rectum
Sarcoma
Bone

How does Radiotherapy work?

Radiotherapy uses high dose radiation to kill cancer cells, hence stopping them from growing and multiplying.

What is the aim of Radiotherapy?

Destroy as many cancer cells as possible while limiting the damage to surrounding normal tissue.
Cure cancers where possible, in combination with other treatments such as chemotherapy and surgery.
Control cancers by shrinking tumours or by stopping them from spreading.
When cure is not possible, radiotherapy may be used to provide pain or symptom relief.

What is the process to start Radiotherapy?

Once you have decided to receive radiotherapy treatment, your doctor will go through a process with you to prepare for treatment.

Your consent will be taken before you start radiotherapy. Your doctor will explain the treatment process, as well as the risks and benefits of radiotherapy. It is important that you understand the information given before signing the consent form. Please ask your doctor if you have any questions.

It may be necessary to have a cast or plastic mask custom-made for you. This helps you stay still during treatment.

How long does the treatment take?

Each radiotherapy treatment session takes about 5-15 minutes. The full course of treatment may range anywhere from 1 day to 9 weeks to complete.

What are the side effects of Radiotherapy?

The side effects of radiotherapy vary from one individual to another. Most side effects are temporary and will gradually resolve within 4-6 weeks after treatment. Your therapy radiographer/ nurse will discuss the side effects you may experience at the beginning of your treatment. Please let your doctor or radiotherapy staffs know if you experience any discomfort.

Note: It is important to ask your doctor if you can use any medicines, creams or remedies other than those prescribed as they may interfere with radiotherapy.

What should I eat during the course of my treatment?

It is recommended that you enjoy a balanced diet and drink plenty of fluids during the course of your treatment.
