Travel insurance policies typically provide coverage for unforeseen events and emergencies that may occur during a trip, such as trip cancellations, medical emergencies, and lost or stolen luggage.

If a traveler has a pre-existing medical condition, such as cancer, it is important to carefully review the policy's terms and conditions to understand what coverage is available. Some travel insurance policies may provide limited or no coverage for pre-existing conditions, while others may offer coverage with certain limitations or restrictions. It's essential to read the policy's fine print and contact the insurance provider to clarify any doubts and ensure that the coverage fits the specific medical needs.

It's also important to disclose any pre-existing medical conditions when purchasing travel insurance, as failure to do so may invalidate the policy's coverage. The insurance provider may require additional documentation to assess the medical condition and determine coverage eligibility.

In summary, travelers with pre-existing medical conditions, including cancer, should carefully review travel insurance policies and disclose any medical conditions to the provider to ensure that the policy provides adequate coverage.
