Chemotherapy acts on fast-dividing cells like cancer but also can affect normal cells hence can cause some side-effects.

Prehabilitation

Prehabilitation enables people with cancer to prepare for treatment by promoting healthy behaviours and prescribing exercise, nutrition and psychological interventions where appropriate to a patient’s needs.   It should be started as early in the patient pathway as is possible, ideally soon after diagnosis, and as well in advance of treatment as possible for maximum benefit.

This is a common term used to refer to a person’s overall sense of wellbeing and satisfaction with life.  While discussing a diagnosis or the treatment options, most doctors discuss how the cancer treatment will affect one’s daily functions, or their ‘quality of life’.

R

Radical

Radical treatment aims to completely cure the disease or control the growth of a tumour. Treatment with curative intent.

Radiotherapy

Radiotherapy uses precise, carefully measured doses of high energy x-rays to treat cancer. Cancer cells are more sensitive to radiation than normal cells. The x-rays either destroy the cancer cells or stop them from growing. Radiation also damages normal cells in or around the area being treated causing side effects, but these will usually recover and heal after treatment. The aim of treatment is to destroy the cancer cells while avoiding and protecting the healthy cells as much as possible.

Radiologists

Doctors who specialise in diagnosing and treating injuries and disease using medical imaging like x-rays, CT scans, MRI scans.

Radiology

An area of medicine that uses imaging technology to diagnose and treat disease.  It can be diagnostic or offer interventional radiology.

Remission

When cancer is being controlled by the treatment.

Remote Monitoring

This is when patients undergoing cancer treatment are monitored in their own homes.  The oncology remote patient monitoring service, sometimes referred to as a cancer virtual ward, monitors and provides support at home to patients who are undergoing chemotherapy and immunotherapy.  The patient will sometimes have an online portal or app to use which links into the hospital.

S

SACT (Systemic Anti-Cancer Therapy)

A group of drugs used in the treatment of cancer by travelling through the body and act on cancer cells, these treatments work on cancer cells anywhere blood is flowing. They can shrink cancer, reduce the chance of cancer coming back or to help boost the effectiveness of radiotherapy. There are several different types including chemotherapy, immunotherapy, hormone therapy and targeted therapy.

Screening tests

Cancer screening tests are used to detect cancer early or find changes in cells that could become cancerous if not treated.  These tests are only available for some types of cancer like colorectal, breast and some gynaecological cancers.

Secondaries

When cancer has spread to another area from the primary site.

Side effects

Supported Self-Management

Being involved in managing your own health.  Understanding what is important to you, knowing what you can do about it, finding out what other help is available.  This will help you to feel more in control of what is happening around you.

Surgery

An operation under a general or local anaesthetic, whereby a surgeon can remove part of or all of the cancer, to repair tissue or to take samples to help diagnose cancer types.

Surveillance scans

Scans done at set intervals to make sure the treatment has been effective or that there is no evidence of your cancer returning. This may be a CT scan or MRI for example.  The results of these will be discussed with you as part of your planned follow up appointments.

Survivorship

Living well after cancer treatment focusing on health and wellbeing.

T

Tumour

An abnormal mass, lump or swelling.  A tumour that is not cancerous is benign, while a cancerous tumour is malignant.

Tumour markers

Substances that can be found in blood, urine, stools, tumour or other bodily fluids that can indicate the presence of cancer or certain benign conditions.  

U

Ultrasound Scan (USS)

An Ultrasound scan uses high frequency sound waves to create an image of the inside of the body. The ultrasound machine uses a small probe that is placed on the skin, there are also smaller probes that can be used internally. A small amount of gel will be applied to the skin over the area the probe will be placed.

V W X Y Z

Vaginal/vulvar cancer

Xray

An invisible electromagnetic energy beams to produce images of internal tissues, bones and organs.  A type of photograph taken of a body part for investigations of symptoms.

You

Remember that you are the most important person in your cancer journey and that the staff are there to care and support you and your family through the difficult time ahead.  Cancer can bring about many thoughts and feelings, and it is important that you are able to talk to people about this.  Your cancer support centre is also available to signpost you to other services and provide information and support that you might need.

ZZZZ’s

Sleep and rest is very important during your treatment.  It is important to speak to your CNS or doctor if this is a problem.
