Doctors at the National University Hospital claim to have become the first in Southeast Asia to treat prostate, cervical and breast cancers using High-dose-rate (HDR) Brachytherapy.
Coupled with 3-D imaging using CT scans and MRIs, the result is a faster and safer option than conventional radiation therapy.
External beam radiotherapy is currently the conventional option for treating higher stage prostate cancer.
But by combining that with HDR Brachytherapy, total treatment time will be cut by nearly half, from eight and a half weeks, to about five weeks.
In HDR Brachytherapy, tiny plastic tubes are first inserted into tumour.
They are then hooked up to a machine that delivers very intense and precise doses of radiation.
CT scans and MRIs allow doctors to map out the cancerous area clearly.
Using a CT scan, doctors will be able to locate the tumour and minimise damage to the surrounding tissue.
So for prostate cancer for example, doctors can decrease the high radiation doses to the bladder and rectum by about 90 per cent, while increasing the total dose to the prostate by 50 per cent.
3-D imaging also increases the accuracy in treating cervical cancer, where brachytherapy is already standard practice.
The procedure can also be used to treat selected early stage breast cancers, or about four in 10 patients.
This is most effective for patients over 50 years of age, with tumours less than 3cm in size, which is completely removed during surgery and where cancerous cells have not spread to the lymph nodes.
Breast brachytherapy can cost up to about S$13,000 ( approx US $10,000), compared to about S$7,000 ( approx $5,000) for standard treatments.
