Pros are

  • better treatment (e.g., IL-5 inhibitor will not help if you do not have a subtype of asthma that is eosinofilic) (by knowing your type the therapy will be more targeted at your subtype of disease)

Cons are

  • more complex diagnostic workup to arrive at personalized care (e.g., must get sequencing results to recommend best action for Lynch syndrome)
