What age range is commonly affected by Thymomas?

Thymomas are tumors arising from the thymus gland, and they are most commonly diagnosed in adults within the age range of 40 to 60 years. This demographic is particularly significant in the context of thymomas because the incidence of these tumors increases with age, peaking during middle adulthood.

This age group is also relevant as thymomas are often associated with autoimmune conditions, particularly myasthenia gravis, which commonly affects individuals in this same age range. Understanding this association helps in the diagnosis and management of patients presenting with thymic tumors.

In contrast, the other age ranges provided do not align with the typical incidence of thymomas, as they are less frequently diagnosed in younger individuals or those over 60, where other conditions or age-related factors may play a more significant role.
