Participants needed for the Polarization sensitive optical coherence tomography (PS-OCT)

Polarization sensitive optical coherence tomography (PS-OCT) skin imaging project

BC Cancer and UBC Biomedical Engineering are collaborating on an innovative new medical imaging system. This project aims to develop a practical and accurate optical method for measuring skin properties. Optical coherence tomography is a non-invasive imaging method best described as “ultrasound but with light”, which allows us to reveal key health properties of the skin. We are looking to make technology that can measure skin properties to both help detect skin cancer, and give clues on how to best treat it.

Who can participate?

  • We are looking to measure on healthy skin in a wide array of skin types.
  • Anyone 18 or over can participate.

Who should not participate?

  • Anyone who would find it difficult to sit still while having measurements taken.
  • Anyone unable to give informed consent in English.

What is involved?

  • Demographic questionnaire (taken on site)
  • Imaging session at a UBC laboratory (1 hour)

What to do if I am interested?

An overview of the study

Participants needed for the Gut Microbiome and Breast Cancer


Dr. Murphy is leading a research study which seeks to understand whether the bacteria in a person’s gut (the microbiome) may play a role in the development of breast cancer. 

Who can participate?

  • Women who are post-menopausal
  • Have either
    • Hormone receptor-positive breast cancer (ER and/or PR) stage I-III and have not yet received therapy
    • OR do not have breast cancer

What's involved?

  • Health questionnaire (online) 
  • Diet history questionnaire (online)
  • Stool sample (a kit will be mailed to you)
  • Blood sample (collected at your local LifeLabs)

What do I do if I am interested?

Complete a 2 minutes screening survey to determine eligibility.
