As per the findings of a new study, published in British Journal of cancer, the scientists have discovered the reason as why the recurrence of cervical cancer happens, despite the body responding well in the treatments.

The researchers blamed it on the medley of the genetic discrepancies, which ascends the chances of immunity cells already being present in the cancer, even before the treatment is initiated.

The study, which recuited six cervical cancer patients, compared the cells at the initial stages with those after the chemotherapy and radiotherapy had been given.

It was found that the genetic material in few cancer cells is not stationary, resulting in to acquiring of accumulate additional genetic faults, over a period of time that were not in the original cell, particularly if the disease is at its developed stage.

Dr. James Brenton, Senior Author at Cambridge Research Institute in UK, who led the study said: "We've discovered that the patchwork of gene faults in the tumours of cervical cancer patients changes throughout the course of treatment. And the more varied the patchwork at the start of treatment, the more likely it is that resistant cells are already present before chemotherapy begins that could go on to re-grow the tumour."

Dr. Lesley Walker, the director at Cancer Research in UK said that these findings suggest that the patients with complex patchwork of genetic faults are in the constant danger zones. She emphasized that the treatments should be tailored, keeping in the view the genetic makeup of every individual patient.
