Can you answer, is white blood cells in your eye any way related to a type of cancer?

Unlikely: White cells in the eye are typically just inflammatory cells and can be present in a number of conditions, such as iritis, or in the post-operative period from eye surgery. Rarely, white cells can indicate the presence of lymphoma in the eye. Other types of cancers in the eye tend to be seen as masses, rather than cells. An ophthalmologist should be able to identify the source of these cells.
