A total of 17 men and women will begin cancer treatment after initially being given the all clear from doctors.
The patients at the Hereford County Hospital were told that their test results were negative but following a review it was found that their diagnoses were wrong, reports the Telegraph.
A further 14 patients at the hospital who were told they did have cancer and begun treatment were later told they did not have the disease.
A consultant at the hospital has since been suspended in light of the findings and legal experts have said that the hospital could be sued.
"It's obviously been a personal disaster for several people who could have been receiving life saving treatment and who thought they were healthy," Sandra Woodward, who runs a cancer support group, told the paper.
It was discovered earlier this year that 102 patients were given wrong diagnoses and 40 people were told that their condition was more serious than first thought.
A spokesman for the hospital told the Telegraph that although the situation was "serious', all patients were now receiving correct treatment.
This follows news yesterday (July 31st) that there may be a breakthrough in gene therapy that could signal new hope for cancer sufferers.
