Advancement in medical knowledge. Boon or bane?

Advancement in medical knowledge to me is definitely a boon. Having more medical knowledge means knowing the signs of a disease or illness and knowing how to deal with it. Being able to identify a disease easily will help stop a pandemic from spreading further and causing mass suffering. Knowing how to effectively deal with an illness will reduce the possibility of mistakes or delays in treatment and allow the patient to live or prevent more suffering for them. Lastly, it also allows researchers to find a cure to illnesses which are presently incurable.
