So this thing started growing on my penis

So, this thing started growing on my penis. Started two weeks ago and has only grown in size, slowly but steadily. I'm a 35 yo male and usually don't take any medication at all, but have been using Ibuprofen and Pantoprazol for 2 months for back pain. Otherwise no health issues at all.

So first question, what is this thing? 2nd, how do I get rid of it? 3rd, what kind of doctor is the right one? Urologist? Dermatologist?

Edit: thanks to all the helpful people in this sub, I took your advice and treated the matter with the necessary urgency it required. I just got back from the urologist and they're sending me to the hospital with the most likely diagnosis being a papillary tumor.
