ENDOTwin: The Canadian Innovation Transforming Endo Diagnosis

Mc Master University/ Hamilton, Ontario

ENDOTwin is a new digital tool developed by Hamilton Health Sciences and McMaster University. It uses real data from real patients to create a personalized “care twin”—a digital profile that highlights what treatment paths have worked for people with similar symptoms, ages, and medical backgrounds.

Think of it as a smart, compassionate assistant whispering to your doctor:

“Here’s what has helped patients like her. Here’s what hasn’t. Here’s the path with the best outcomes.”

For decades, endometriosis treatment has been like navigating in the dark.Every patient is unique, every symptom looks different, and doctors often rely on trial-and-error.

Tools like ENDOTwin change that.

They provide:

• More personalized care plans

• Fewer unnecessary medications

• Faster referrals and treatment decisions

• Better preparation for surgery

• Data-driven predictions of what might help you

  
  

It’s the beginning of precision medicine for endometriosis—something this community has waited far too long for. If tools like ENDOTwin spread across Canada, patients could finally experience:

• Shorter diagnostic delays

• Less medical gaslighting

• More accurate imaging referrals

• Better surgical outcomes

• More consistent standards between provinces

  
  

Instead of isolated clinics working alone, we could have a nationally connected system where every patient contributes to better care for the next.

Innovations like ENDOTwin give us hope. Finally, we’re seeing technology that respects patient experiences and understands the complexity of endometriosis.

This could truly reshape the future of women’s health in Canada — and we’re ready for it.
