More than 1,000 patients were waiting for routine treatment at the Solent Trust in January, figures show.

The figures come as a leading cancer campaigner calls on the Government to launch a dedicated plan to tackle the backlog in cancer treatment.

NHS England figures show 1,279 patients were waiting for non-urgent elective operations or treatment at Solent NHS Trust at the end of January – up from 1,198 in December, and 952 in January last year.

None of those had been waiting for longer than a year.

The median waiting time from referral at an NHS Trust to treatment at the Solent Trust was nine weeks at the end of January – up from eight weeks in December.

Nationally, 7.2 million people were waiting to start treatment at the end of January.

Professor Pat Price, co-founder of the #CatchUpWithCancer campaign and leading oncologist, said: “Today’s data shows, yet again, more patients waiting longer than ever before for life-saving cancer treatment.”

“Without a cancer plan and investment into treatment solutions, such as radiotherapy, I am worried that each month the number of cancer patients missing life-saving targets will continue to swell.”

The Nuffield Trust said NHS will be straining to deliver services for "years to come".

Dr Billy Palmer, Senior Fellow at the organisation, added: “The concerning consequence of the unrelenting pressure on the NHS is that patient safety is being compromised.”

Other figures show 1.6 million patients in England were waiting for a key diagnostic test in January – a rise on 1.5 million in December.

At the Solent Trust, 250 patients were waiting for Magnetic Resonance Imaging.

Of them, two (1%) had been waiting for at least six weeks.

NHS national medical director Professor Stephen Powis said despite strikes and respiratory illnesses over the winter, NHS staff "continued to deliver for patients, bringing down elective waits, treating more cancer patients and delivering more diagnostic tests for people than ever before."

He said: “The NHS will not stop in its efforts to bring down 18 month waits for elective care and bring down the cancer backlog, but it is inevitable that if the upcoming junior doctors strikes happen they will have a significant impact on cancer care and routine operations that were scheduled to happen.

“As ever, we will do all we can to limit the impact to patients,” he added.
