How to monetize medical traffic?

Question

Monetization

There is medical traffic, about 20 thousand impressions per day of advertising banners. Mobile applications. Traffic in the RU segment (in different cities of Russia). In the presence of embedded GA analytics (indicators, charts, everything is available and ready for presentation).
Please advise whether it makes sense to move towards interacting with advertisers directly, or is it better to stay on adMob with such input data?
If profit is possible, where to start and who to contact?
