Oncology

San Antonio

92 businesses listed, showing 1–40. How we order them.

San Antonio's oncology category lists 92 entries, and the gap worth noticing isn't the count itself but what sits behind each name. Every one of those 92 listings carries a phone number, but only 81 also list a website, so a fair number of these practices are reachable by call alone. Clusters show up around zip 78240, which holds 19 listings, and 78217 and 78229 each with 26, so if you're searching near those areas you'll find more options nearby than in zips like 78212 or 78235, which show 6 apiece. None of this reflects quality or wait times, just where offices happen to be registered.

Paid placement hasn't launched in this category yet, so nothing here is boosted, sorted, or flagged as Sponsored, meaning the order reflects the data as entered, not a bought position. If you manage one of these oncology practices and see a missing website or an outdated line, you can claim the listing and correct it yourself, which matters most for the entries still running on phone contact only. Treat this page as a starting point: call two or three, confirm details directly, and don't assume placement on the page means anything about care.
