When it comes to brain cancers, precise and efficient tools like the Gamma Knife have changed the way treatment is conducted on patients.
While many tend to become anxious when they hear the word “radiation”, Dr Malwinder Singh, a clinical oncologist at Pantai Hospital Kuala Lumpur, says that the Gamma Knife procedure is actually much safer. “In normal radiotherapy, a big portion of the brain gets radiated, probably a few centimetres of brain tissue. But with Gamma Knife, you are talking about mere millimetres of normal tissue exposed to radiation,” he says.It also comes with the added ability to differ and specify radiation doses, based on the size of the growths and lesions.
“Not all tumours are the same. The average sized ones, you can treat it all at once. Whereas big tumours might be fractionated due to the size. You can treat everything in one round, and the big tumour might need a second round of treatment.” He adds that there is little to no pain during procedures, and that hair fall is rare while undergoing treatment, although it can occur if the growth or tumour is peripherally located in the brain.“For Gamma Knife procedures, sometimes we will discharge patients with medication for a few days to alleviate any symptoms. The toxicity will only last about two to three days in the body, a week at most.
