I do not quite understand the question in order to answer it clearly. Was there previously no personaliized treatment?

Is personalized medicine meant? .....Personal medicine is one of the topics of interest in biotechnology. While some have high hopes for this type of medicine in the treatment of intractable diseases such as cancer, others warn of the rush to rule. Personal medicine depends on the doctor to know the causes of the disease accurately, the appropriate diagnosis helps doctors to treat the patient accurately.

Hi Dr Hein

I think precision and personalized medicines are new developments.

thanks.

" Personalized healthcare is about helping physicians identify patients who may be eligible for appropriate treatment options. We start with an intricate understanding of the biology of the disease, then use that knowledge to identify biomarkers: biological molecules found in body fluids or tissues that provide insight into the state of the disease, such as gene mutations or protein expressions. Finally, we leverage biomarker tests, known as companion diagnostics, which doctors can use to inform treatment decisions for individual patients.

While so-called “personalized medicines” have existed for more than a decade, advances in science and technology have made diagnostics smarter, more targeted, and more accessible. We’re excited that AstraZeneca is consistently at the forefront of this science, analyzing gene mutations and protein expression, developing targeted therapies, and working with leading diagnostic partners to develop tests.

Ultimately, personalized healthcare is about more than medicine: it is a philosophy that guides our approach to research, delivery, and everything in between as we work to improve the lives of patients whom we serve"(https://www.astrazeneca-us.com/media/astrazeneca-us-blog/2016/personalized-healthcare-what-it-means-and-why-it-matters-11282016.html).
