List of Oncologists in United States
The United States has 36,530 oncologists in this dataset, last verified September 9, 2026. California leads with 3,783, ahead of New York (2,564) and Texas (2,384). Together the top three states account for just 24% of the market, and it takes 9 of 46 states to reach half of all records, so oncologists are spread widely across the country rather than clustered in a few markets.
Phone is the dominant contact channel for oncologists: 35,822 records (98.1%) include a direct phone number, while 10,326 (28.3%) include an email address and 10,262 carry both, enabling multi-channel outreach.
Web presence is close to universal: 79.4% of oncologists in the United States have a website and only 7,515 do not, so agencies will find more demand for redesigns and SEO than for first-time builds. Of the websites on record, 8,311 (29%) include a contact page URL.
56% of oncologists carry Google ratings, and among rated businesses 71% hold a 5-star average, a heavily skewed distribution typical of small operators with few reviews. The 1,183 businesses rated 1 to 2 stars are candidates for reputation management outreach.
