Possibly, and that assessment belongs to your own treating clinician and the operator's medical review rather than to us. What's worth understanding going in is the environment they're assessing against: limited diagnostic equipment, evacuation that can be delayed by days, rough seas, stairs, cold exposure and landings that change with the weather.
Give the operator complete and current information rather than the minimum. Three questions worth asking them directly: can this ship manage my condition, is specialist clearance required, and does my insurance cover complications related to it.
The insurance side matters as much as the medical one. Pre-existing condition cover varies by policy, purchase date, medical history, stability period, disclosure and whether a waiver was bought in time. Ask a licensed insurance agent about the exact definition, the look-back period and the waiver deadline, and disclose the condition separately to the operator's screening team. Those are two different disclosures and doing one doesn't cover the other.
