I've had a small squamous cell carcinoma of the eye removed (<5mm). treatment with mitomycin during removal only. any suggested follow up procedures?

Follow up needed!: The nice thing here is that you can be followed up clinically and observed. Follow your surgeon's directions. Should likely be seen every 4-6 months for a 2 years or so. If no recurrence, then at least annually!

Conjunctiva SCC?: Sorry - difficult to understand what you exactly had based on your question. The anatomical sites that are potential possibilities - conjunctiva, lacrimal gland, skin of eyelid. However based on your treatment it appears you probably had conjunctiva. Would suggest close follow-up with your ophthalmologist and/or oncologist. Best regards to you.
