Feasibility of Comparing Microwave Images and Mammograms in Patients Recalled for Follow-up Breast Imaging

This study is looking into a new, safe way to scan breasts using microwaves. The aim is to see if these microwave scans can provide similar information to standard mammograms for women who have been called back for more breast imaging after a screening. Researchers want to compare the details captured by the microwave scanner, like breast positioning and tissue types, with what's seen on a mammogram. They'll also check if the microwave scanner can identify areas that look unusual on a mammogram. Participants will have quick, low-power microwave scans on the same day as their follow-up appointment and answer a few short questionnaires.

What is this study about?

This study is exploring a new way to look at breast tissue using gentle microwave technology. Think of it like a different kind of scanner that uses very low-power microwaves, so there's no risk of heating or harming your tissues. The main idea is to see if this new scanner can provide useful information about your breasts, especially if you've been called back for more checks after a routine mammogram.

The researchers want to compare the images and information from the microwave scanner with what your doctor sees on your mammograms. They're specifically interested in whether the microwave scan can show similar details about breast positioning and different tissue types. They also want to see if the microwave scanner can highlight any specific 'areas of interest' that might have been spotted on your mammogram.

This research is important because it could lead to new tools for breast imaging in the future. By carefully comparing this new technology with existing methods, scientists can better understand its potential. This study builds on previous work by this research team, who have safely tested earlier versions of this microwave scanner on healthy volunteers and patients.

Key takeaways

  • The study tests a new, safe microwave scanning method for breast imaging.
  • It compares microwave images with standard mammograms for women recalled for follow-up.
  • Participation involves quick, low-power scans on the same day as your existing appointment.
  • The scans won't replace your standard medical care; they are for research only.
  • Your input helps develop future breast imaging technologies.
  • You can withdraw from the study at any time without affecting your medical care.

Who may be eligible?

This study is for women aged between 18 and 74 years old. To join, you must have had a screening mammogram within the last six weeks that led to you being called back for more breast imaging, specifically due to findings that are rated as BIRADS 3 or 4. Also, you need to be able to understand and agree to take part.

There are a few reasons why you might not be able to join. For example, if you haven't had a recent mammogram, are currently being treated for breast cancer, or have received treatment in the past six months, you wouldn't be eligible. The study also isn't suitable for women who are pregnant or breastfeeding, have breast implants, a breast skin infection, or certain electronic devices implanted in their body. If you have nipple piercings, you would need to remove them before the scan, and you need to be able to comfortably position your breasts in the scanner.

Could this study suit you?

Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.

  1. I am a woman between 18 and 74 years old.
  2. I had a recent mammogram (within last 6 weeks) and was called back for follow-up due to a BIRADS 3 or 4 finding.
  3. I do not have breast implants.
  4. I am not pregnant or breastfeeding.
  5. I am not currently being treated for breast cancer, nor have I been treated in the last 6 months.
  6. I do not have an implanted electronic device or an active breast skin infection.
Answer every question to see your result.

What does participation involve?

If you decide to take part in this study, your involvement will be quite straightforward and will happen on the same day as your existing follow-up breast imaging appointment. You won't need any extra visits.

During this single session, you will have both of your breasts scanned using the special Wave View microwave scanner. Each breast will be scanned up to three times. The scanner will be positioned horizontally sometimes and at a 45-degree angle at other times to get different views. The scans are quick and use very low power. You'll also be asked to complete three short questionnaires. One will be about your general breast health, and the other two will ask about your experience with the microwave scanning process. There are no medications involved in this study, and your total participation will be completed within that single appointment.

Potential risks and benefits

There are no expected risks from the microwave scans themselves, as they use very low power and will not heat or harm your tissues. You have the right to withdraw from the study at any time without giving a reason, and this will not affect your care. While there's no direct benefit to you from taking part, your contribution will be valuable. It will help researchers understand if this new microwave technology could be a useful tool for breast imaging in the future, potentially leading to improved diagnostic methods for many women.

Common questions

What is BIRADS 3 or 4?

BIRADS is a system doctors use to describe what they see on mammograms. A BIRADS 3 means it's probably normal but needs a check-up later, and a BIRADS 4 means there's something suspicious that needs further investigation. This study is for women recalled for these types of findings.

Will the microwave scanner hurt?

No, the microwave scanner uses very low power, so it won't cause any pain or heating of your breast tissue. It's designed to be safe and comfortable.

How long will the study take?

Your participation will only take place on the day of your scheduled follow-up breast imaging appointment. It's a single session, and you won't need to come back for the study specifically.

Do I have to do anything special to prepare?

You just need to attend your scheduled follow-up breast imaging appointment. If you have nipple piercings, you'll need to remove them before the microwave scan.

Will I get results from the microwave scan?

The microwave scan is experimental, so the results won't be used to guide your immediate medical care. The information gathered will be for research purposes to compare with your mammogram results.
