New cancer treatment 'can reduce radiation damage'

Fox Chase Cancer Center

Radiosurgery cancer treatment could become quicker and minimise tissue damage, according to a new report.


Scientists at Fox Chase Cancer Center have developed a new technique that can follow the exact contour lines of a tumour.


Radiosurgery focuses beams of high-energy X-rays capable of ablating a lesion that may otherwise be inoperable, but the procedure is relatively rigid and struggles when operating on irregular tumours.


The new research used a multileaf collimator (MLC) to flexibly move the radiation beam around any tumours.


Results revealed the MLC operations were around ten times quicker and greatly reduced the amount of radiation focused upon surrounding tissues and organs.


"We can spare the critical structures around tumours much better, providing the ability to treat the tumour to a higher dose without increasing the normal tissue toxicity," said Jiajin Fan, a radiation oncology physicist at Fox Chase.


Cancer Research UK states there are not many side effects to radiosurgery.
