The cancer registry explained

5 minute read time.

Have you heard of the cancer registry? It’s the automatic collection of data about people and cancer to help with research and cancer care. In today’s blog, Library and Information Specialist Ed demystifies the cancer registry.

Every day around 1,000 people across the UK will find out that they have cancer. It’s estimated that half of all people will receive a cancer diagnosis at some point in their lives. However, great steps have been made in understanding what causes cancer and how best to diagnose and treat it.

Today, people are twice as likely to survive at least 10 years after being diagnosed with cancer then they were at the start of the 1970s. This progress is greatly helped by the collection of accurate and complete information about the people who get cancer. This information is collected through something called the cancer registry.

This infographic from 2015. It is called 'Cancer: a colossal challenge'. It shows the '2.5 million segmentation'. This is represented by a icons of people, showing how many people are living with cancer in the UK. These numbers are from 2015. There were 2.5 million people living with cancer in the UK This number had grown by an extra 400,000 people over just five years.

Why is it important that detailed data on everyone with cancer is collected?
This information helps:

  • find cancer earlier
  • understand why some people get cancer and others do not
  • find the right treatment for each person.

The data that is collected provides information on how many people are diagnosed with cancer, what treatments they have, and how long they live.

This information can then be used to:

  • help investigate causes of cancer
  • support and plan cancer services and patient care
  • identify where further progress is needed
  • improve the lives of all people affected by cancer.

How is the data collected?
When a person is diagnosed with cancer, information about them is automatically sent by hospitals and healthcare professionals to the cancer registry in the relevant country. The registries contain information about each person who has been diagnosed with cancer.

This includes: 

  • their name and address
  • their age
  • their gender
  • their date of birth
  • the cancer type
  • when and how they were diagnosed
  • what treatments they have had.

Information about outcomes, such as the date that treatment ended, may also be included if relevant.

Because it is so helpful to know about every case of cancer in the population, cancer registries have been given legal permission to collect patient information without needing to ask the individual. However, you have a right to choose not to have information about you or your child stored in the registry. Contact the cancer registry in your country to do this - see below for details. This will not affect the care that you or your child is given.

There are strict rules to make the sure that the information in the registries is kept safely and securely. Cancer registries take great care to keep the information they hold about patients confidential. As with other medical records, ethical and security safeguards are in place and access is controlled.

Who collects the data?
The collection of data on cancer is managed by specific agencies in each of the four UK nations:

The United Kingdom and Ireland Association of Cancer Registries (UKIACR) is an umbrella organisation for all the above cancer registration services. It aims to promote and develop cancer registration in England, Wales, Scotland, Northern Ireland, as well as the Republic of Ireland (National Cancer Registry Ireland).
