Salaries for oncology professionals vary widely internationally. In countries like Canada and the United Kingdom, oncologists earn less than their U.S. counterparts, with average salaries around $200,000 to $300,000. In contrast, oncologists in countries with lower healthcare spending may earn significantly less, sometimes under $100,000 annually. However, these figures can be influenced by factors such as the cost of living, healthcare infrastructure, and the country's economic status.
