• Primary Care Skin Cancer Screening & Early Detection (Suspicious Mole/Lesion Assessment): Educating patients on sun safety measures (sunscreen, protective clothing, avoiding peak sun hours), the importance of regular skin self-examination using the ABCDEs of melanoma, and encouraging prompt reporting of any changing or new skin lesions.
• Viral Skin Infections (Common Warts, Molluscum Contagiosum, Herpes Simplex, Herpes Zoster/Shingles): Providing effective treatment for various viral skin conditions to alleviate symptoms, shorten duration of outbreaks, prevent complications (like PHN or secondary bacterial infection), and reduce transmission where applicable.

It may take time to find a doctor.

Medically necessary visits to a family doctor are typically covered by the Ontario Health Insurance Plan (OHIP) for eligible residents with a valid health card.

What exactly is a family doctor (Family Doctor) and what is their role?

A family doctor (Ontario) is a physician who has completed post-graduate training in family medicine. They are skilled in providing continuous and comprehensive medical care, health maintenance, and preventive services to patients of all ages. This includes diagnosing and treating a vast array of illnesses, managing complex long-term health conditions, offering health education and counseling on lifestyle choices, and acting as your advocate and guide within the broader healthcare system.

What is 'continuity of care' and why is it important with a family doctor like Dr. Sun?

Continuity of care refers to the process where your family doctor, Dr. Sun, sees you for your health needs on an ongoing basis, rather than seeing different doctors for different issues. This consistency is valuable because Dr. Sun becomes familiar with your medical background, your lifestyle, and what's 'normal' for you. This knowledge aids in quicker diagnosis, more effective treatment plans, better chronic disease management, and ensures that your care is well-coordinated across the healthcare system. It's about having a trusted healthcare partner throughout your life.
