Associate Professor Vardy's research team found patients who received chemotherapy were no worse off.
"We were expecting the cancer patients who had received chemotherapy to have more cognitive impairment than those who did not go on to receive chemotherapy, but in fact there was very little difference between the two cancer groups with localised disease.
"So the nickname that's been given of 'chemo brain' is not very accurate and it's probably something more like a 'cancer brain'."
The paper, published in the Journal of Clinical Oncology, focused on bowel cancer, but researchers believe the results would be similar for many cancers.
The researchers did not find what caused the decline in cognitive ability.
Co-author Dr Haryana Dhillon said that made treatment a challenge.
"It's a little bit difficult for us to give solid advice about this, but on the basis of some of the work that's been done in other areas, and in particular in animals studies, which is probably that physical activity is something that can potentially help to preserve and protect cognitive function in cancer patients and cancer survivors.
"And there's a possibility that some brain training exercises might help as well."
This study shows cognitive impairment in bowel cancer patients last for at least two years after diagnosis.
Whether the concentration and memory lapses continue beyond that will be the focus of follow up research.
