What is an IUD insertion like? Does Dr. Hall perform this?

Does Dr. Hall discuss or offer the HPV vaccine?

The Human Papillomavirus (HPV) vaccine is highly effective in preventing infections with HPV types that cause most cervical cancers, as well as other anogenital and oropharyngeal cancers. Dr. Hall can discuss the benefits of the HPV vaccine, current recommendations for different age groups (including catch-up vaccination for adults), and can either provide the vaccine or refer you to where it can be obtained, depending on clinic services and provincial programs.

I have uterine fibroids. What treatment options might Dr. Hall suggest?

Treatment for uterine fibroids depends on their size, number, location, and the severity of your symptoms (like heavy bleeding or pain), as well as your reproductive goals. Options range from watchful waiting for asymptomatic fibroids, to medications (hormonal therapies to manage symptoms), to minimally invasive procedures (like uterine artery embolization - often by interventional radiology), or surgical removal of fibroids (myomectomy) or the uterus (hysterectomy). Dr. Hall will help you decide the best course of action.
