Which of the following is an example of a disability protected under the ADA?

Cancer is recognized as a disability under the Americans with Disabilities Act (ADA) because it substantially limits one or more major life activities. This classification applies regardless of whether the individual is currently undergoing treatment or in remission. The law is designed to ensure that individuals with such conditions receive equal opportunities and protection from discrimination in the workplace and other public domains.

In contrast, seasonal allergies, minor injuries, and temporary illnesses may not necessarily meet the threshold of being a disability as defined by the ADA. Seasonal allergies can often be managed and may not significantly restrict an individual's ability to perform major life activities. Minor injuries usually do not result in long-term or significant limitations, and temporary illnesses, by definition, are not expected to have lasting effects that would interfere with daily activities. Therefore, only conditions like cancer that can impose serious, long-lasting effects qualify for protections under the ADA.
