I'm seeing a lot of people here are associating TC with hereditary. Cancer isn't hereditary, as it won't stem from a single gene in the DNA strand that is passed onto you, but it can widen your chances obviously for such things to occur. Your father, or grandfather does not need to have had TC for you to get it, which is a great misconception.
Thought I'd clear that up.

As for the gentleman on the boat, please attempt to speak with the medical officer in sickbay, and ask him to have a look. They're pretty well versed in medicine, being the last resort for most on a ship out at seas for weeks. They have to be. Ask him to have a look, and maybe he can give you his idea on the severity. It might be cause to get you off the boat sooner rather than later, which would put your mind at ease if you could get to work on finding out what it is.
