We had an odd experience the only time we ever went to the ship's medical facility. My husband had surgical treatment for early cancer about 1 year prior to our Caribbean cruise. He was followed up closely and routinely with no issues. Midway through the cruise one of his eyes ( and the area around it) swelled up significantly and was tearing constantly. I'm a nurse so we don't normally rush to the doctor but it kept getting worse so we decided to go. I wanted to make sure it wasn't pink eye and be contagious. The physician evaluated my husband, drew labs, started an IV and observed him for a few hours. Then he quietly sat us down in a room and said this... " I'm sorry to tell you but your husband has had his cancer metastasized to his eye. He needs to get off at the next stop (I think it was Barbados) and go immediately to the hospital and get a CT scan." After my heart sunk when he said the word cancer I took a deep breath and calmed down. We didn't get off and go to the hospital but 2 days later the swelling was gone.We saw our doctor upon arriving home who felt he had an allergic reaction. That was almost 10 years ago. I can laugh about it now but at the time it was scary.
