What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published

Summary

This study tests whether a mobile application can help breast cancer survivors prevent lymphedema, a common and often permanent swelling of the arm after surgery. Participants who had breast cancer surgery at least one month ago will be randomly assigned to use the app or receive standard care. The app provides information and exercise guidance to support lifelong self-management. Researchers will measure changes in self-management skills and self-esteem to see if the app makes a difference.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
a mobile application providing lymphedema information and exercise guidance
What this could lead to
If effective, this mobile app could offer a simple, accessible way for breast cancer survivors to reduce their risk of lymphedema and improve self-management.
What could go wrong
This is a relatively small, early-stage study measuring self-reported outcomes, so results may not be generalizable. The app's effectiveness depends on consistent user engagement.
