Is the pin-head-sized bump on my penis a pre-cancer symptom?

Hi doctor,

I am a 63-year-old male. I have been smoking for 35 years, and I am uncircumcised. I remember having very few rashes in the past, either cleared up by itself or with an ointment. I cannot recall all details because it was many years ago. I noticed this past rash because I felt like a tingling sensation then pulled the foreskin back, and it was reddish patches on the head and coronal area on my right side. I did not have itching or pain. I bought some OTC creams, which turned red to pink, and it got better in two weeks or so. After wearing a condom, it flared up slightly but not as red as when I first discovered it. Then I noticed a tiny white patch under the foreskin, which looked kind of warty, maybe. It also had two to three round raised bumps with a hard small white dome. By then, about one month had gone. I went to urgent care, and I started using the antibiotic ointment for one week, which cleared the white patch and the pimple white top things. I have been taking salt baths to keep it clean too. A few days ago, I pulled the skin back and saw one to three tiny drops of blood coming close to where the peeing hole is, but it was on the distal side of the head. I put tissue, and it stopped. I only noticed a small, very tiny scratch or an abrasion from where the drops of blood oozed. That has not occurred again, and it has been over two weeks now. I might have scratched the sensitive skin with my pants zipper or something. The thing that worries me is a little more minor than a pinhead-sized white head that feels like a splinter under the white part. It is behind the right side coronal between sulcus and beginning of shaft. I also have tiny goosebumps on my head, which get inflamed after sex but just for a few hours. I started using the antibiotic cream again this week because of that tiny pimple. Overall, the condition is way better than two to three months ago when it began. I am retired and have low income and freaked out if a urologist or dermatologist might discover it as penile cancer, which I have read is a horrible disease. I want to know if it is a pre-cancer symptom? Also, is the cream I am using masking the symptoms since things have pretty much cleared up? I also noticed a foul odor just recently for two days, but it has subsided now.

Thank you doctor,

Sorry, I will send some more images. The reason it looks moist is I put some antibiotic cream after a salt bath. Let me know if you need more photos. I will ask my wife to take some.
