What is the Generations Study?

The Generations Study is a long-running UK research project investigating the causes of breast cancer, following more than 110,000 women. It is run under the Breast Cancer Now banner and is designed to advance prevention and improve outcomes over time.

It is a cohort study, meaning it tracks a large group of participants over many years and looks for patterns linking genetics, lifestyle, hormones and other factors to who develops breast cancer and how they fare. That design lets researchers study causes rather than just describe cases, and it supports work on risk prediction and prevention.

Who it is for

• Women in the UK who want to understand or contribute to breast cancer research.
• Researchers and clinicians looking for a large, established study population and long-term data.
• Journalists, students and patients seeking a plain explanation of how cohort research works.

What you will find on the site

• An overview of the study, its origins and its purposes.
• Scientific aims, so you can see what questions the research is trying to answer.
• A description of the study population.
• Contact details for the study team.

Practical next step

If you are deciding whether to take part, read the study population and scientific aims first. They tell you who the research is designed to represent and what participation involves. If you are a researcher, the aims section is the fastest way to judge whether the study's scope matches your question. If you are simply curious, start with the overview, then the scientific aims, and treat the contact page as the route for specific questions rather than general reading.

A useful comparison to keep in mind: a cohort study like this is strongest for finding causes and tracking change over decades, but it is not a source of immediate clinical advice or individual results. For personal medical decisions, speak to a clinician; use this site to understand the research landscape.

How can UK women join the Generations Study?

The Generations Study is not currently open to new participants. Its own pages describe it as a long-running UK study of the causes of breast cancer that has already recruited over 110,000 women, and the site's main calls to action are to learn about the study and to contact the team — not to sign up. So for a UK woman reading this today, the practical answer is: you cannot join through the website as a new volunteer.

H3 What you can do instead

• If you are already a participant, the site's "Contact us" route is the right channel for questions about your involvement, questionnaires or follow-up.
• If you want to take part in research, look for studies that are actively recruiting. UK-wide registers such as NHS research pages and [[site:be Part of Research|Be Part of Research]] let you search by condition, location and study type; charity research pages such as Breast Cancer Now and Cancer Research UK also list opportunities.
• If your interest is prevention specifically, ask whether a study needs women with or without a family history, and whether it involves questionnaires only or clinic visits — that difference usually decides whether it fits your life.

H3 How to judge whether a study suits you

A useful next step: contact the Generations Study team through the site's contact page if you are unsure whether you are already enrolled, or search an active UK research register if you want to volunteer now.

What are the main scientific aims of the Generations Study?

The Generations Study is a long-term UK cohort study of breast cancer causes, run under Breast Cancer Now and following more than 110,000 women. Its scientific aims, as set out on Generations Study, centre on understanding why breast cancer develops and how it can be prevented, rather than on testing a single treatment.

Main scientific aims

• Identify causes and risk factors. The study collects lifestyle, reproductive, hormonal and environmental information over many years so researchers can link exposures to later breast cancer diagnoses. This is the core of its design: women are recruited before outcomes are known, then followed up.
• Understand the role of genetics and family history. By combining questionnaire data with biological samples, the study supports work on inherited susceptibility and how genes interact with other risk factors.
• Improve risk prediction. A study of this size can help refine models that estimate an individual woman's likelihood of developing breast cancer, which matters for targeting screening or preventive options.
• Support prevention research. The stated framing—"advancing breast cancer prevention and outcomes"—points to using findings to inform preventive strategies, not just to describe risk.
• Examine outcomes and survival. "Outcomes" in the heading suggests interest in what happens after diagnosis, including factors that influence prognosis.

How the design serves those aims

A cohort of this scale is valuable because it can detect modest effects that smaller studies miss, and because it captures exposures before disease onset, reducing some recall bias. The trade-off is time: answers about prevention and outcomes emerge over decades, not months, and participants must stay engaged for the study to remain useful.

Practical next step

If you want the precise, current list rather than a summary, read the "Scientific Aims" section on the study's own site, then check the "About the Study" and "Study Population" pages to see how each aim is operationalised. For a reader deciding whether the findings are relevant to them, the key question is whether a stated aim addresses a risk factor or prevention option they can actually act on—those are the sections worth reading in full.

How does the Generations Study protect participants' data and privacy?

The Generations Study does not present a detailed public breakdown of its data-protection and privacy procedures on the page supplied. What it does show is the scale and nature of the project: a UK-wide scientific study of the causes of breast cancer involving over 110,000 women, run under Breast Cancer Now, with a contact route for participants.

That combination matters for privacy. A study of this size holds decades of health, lifestyle and biological information, so the practical safeguards usually sit in the study's ethics approvals, consent materials and participant information, not in a short public summary.

What to check as a participant

If you are taking part, or considering it, the most reliable sources are the documents you were given:

• Participant information sheet — explains what data is collected, why, and for how long it is kept.
• Consent form — sets out what you have agreed to, including any optional parts such as extra samples or future research.
• Privacy notice — covers your rights over your data and how to exercise them.
• Ethics committee approval — indicates independent review of how participants are treated.
• Contact point — the study's own contact page is the place to ask about access, withdrawal or concerns.

A practical next step

If your question is about your own records, contact the study directly and ask three specific things: what data is held about you, who can access it, and how to request withdrawal or deletion. For general reassurance, read the participant information and privacy notice, since those documents — not a website overview — carry the binding detail.

What has the Generations Study discovered about breast cancer risk factors so far?

The Generations Study page itself does not list specific findings; it describes a long-running UK cohort of over 110,000 women set up to investigate the causes of breast cancer. So the honest answer is: the study's own introduction explains its scale and purpose, but you need its published results to see what it has found.

What the study is built to examine

Because it follows such a large group of women over many years, it is designed to look at how genetics, hormones, lifestyle and other exposures relate to who develops breast cancer. That design is what makes findings about risk factors possible at all — it can compare women who develop the disease with those who do not, within the same population.

Where to find the actual discoveries

• Breast Cancer Now — the charity behind the study; its research pages and news releases summarise findings for a general audience.
• Cancer Research UK — independent summaries of breast cancer risk factors and the evidence behind them.
• PubMed — search "Generations Study breast cancer" to read the peer-reviewed papers directly.

A practical next step

If you want to know whether a particular factor (say, alcohol, HRT or family history) has been linked to risk, search PubMed for the factor plus "Generations Study". That will show you what this cohort has actually contributed, rather than what the study hopes to examine.

Keep in mind that a cohort like this produces many separate findings over time, and individual results are usually about associations and probabilities, not certainties for any one person.

How do I contact the Generations Study team or update my details?

Contact the Generations Study team through the "Contact us" link on Generations Study, which is the route the site gives for getting in touch. The same page is the natural place to ask about updating your details as a participant, since the study's own contact channel will know what identifier or information it needs from you.

If you are a participant updating your details

The site does not spell out a self-service form, so treat the contact route as your starting point. When you write, include:

• Your full name as registered with the study
• Any previous name or address the study may hold
• Your participant or study reference number, if you have one
• The specific change: new address, new phone number, new email, change of name, or a request to stop receiving mail
• The date the change takes effect

If you are not a participant

Use the same contact page for general enquiries about the study, its origins, its scientific aims, or its study population. The site describes it as a large study of the causes of breast cancer involving over 110,000 women from the UK, so if your question is about taking part, ask whether recruitment is open rather than assuming you can join.

A practical next step

Before you send anything, have your reference number and old details to hand. If you have moved and also changed your name, report both in one message so the study's records stay consistent, and ask for confirmation that the update has been made.
