Breast Cancer Radiation Therapy in One Shot-30 minutes
Radiation therapy for patients with breast cancer could soon be a simple thing, a matter of just a single dose of 30 minutes, instead of the current tedious procedure lasting more than six weeks.
In a major breakthrough, a team of British doctors headed by University College London’s Dr Jayant S Vaidya — an Indian from Goa — has succesfully tested a new technique that will tear down the remains of a tumor within the breast in one shot, lasting half an hour. The team makes use of radiation in areas just around the tumor instead of the entire breast, as is currently done.
A test of 10 years of this selective intraoperative radiation therapy (TIR) conducted in nine countries involving more than 2,200 women confirmed that the orientation of radiation in a specific area of the breast was as effective as whole breast radiation in reducing recurrence of breast cancer in women.
The results of this study was published in the latest edition of the medical journal The Lancet.
Thus, while the patient is still under anesthesia after removal of the tumor, a series of soft X-rays is administered to destroy tumor cells that remain in the area of cancer. The technique is very convenient, requiring only one session of radiation, making it less time consuming and less costly than treating the entire breast.
“Breast cancer is usually repeated around the area where the tumor was first detected. So it makes sense to concentrated doses of radiation to tissues at higher risk of cancer recurrence rather than the entire breast,” says Vaidya.
