While this is a slight improvement from 2023 - where only 60.1% of patients were treated on time - cancer charity coalition One Cancer Voice is warning the improvement is not enough to reach the government's target of 85% treated within two months.
Overall waiting times at A&E in January were slightly improved on December and last January, with 71.1% of patients being admitted, transferred or discharged within four hours.
Health and Social Care Secretary Wes Streeting said: "Through the prime minister's Plan for Change, the government has already cut NHS waiting lists by almost 160,000 since July, through a combination of investment and reform.
It comes as more than 50 cancer charities have called on the government to tackle waiting times in England as data showed 74,000 patients were not treated in time last year.
The number of patients waiting for 12 hours in A&E after a decision has been made to admit them - known as a "trolley-wait" - rose above 60,000 for the first time in January.
