Medical researchers have found a new method to kill tumours by freezing them. With this new method, no more painful surgery will be needed for breast cancer patients.
Cryoablation Vs Chemotherapy
This technique called Cryoablation uses a supercooled needle as cold as -170 degree Celsius to freeze tumorous tissues. This process only kills harmful tissues while leaving healthy cells unharmed.
Such low temperature of the needle is obtained by pumping liquified Nitrogen through a cluster of little thin tubes. The surgeon doing the treatment can also control the size of the ice ball according to the tumour size. Cryoablation is very easy and doesn’t uses any anaesthetic and takes just about 15 minutes to complete. The researchers revealed that the technique can cure breast tumours of size as large as a golf ball. This new technique of Cryoablation will be also helpful in other types of cancers such as those in kidney, prostate and liver.
The current method of surgery and Chemotherapy are painful for breast cancer victims. They use anaesthetics and also leave scar marks on the screen. Also, the women need to stay at the hospital for a week.
Earlier attempts of killing tumorous tissues using heat failed because human body and cells couldn’t sustain too much heat. This is not the case with cold. Human body can tolerate extremely cold temperatures. Also, low temperature acts as anaesthetics. Human cells have water percentage higher than 70%. Tumorous cells are easily vulnerable to cold temperatures than healthy cells. So, it is easy to freeze and kill them.
Cryoablation Trial and Results
Cryoablation Breast Treatment trial is to be done on 30 breast cancer patients. Dr Eisuke Fukuma, Director for Breast Cancer at the Kameda Medical Centre in Chiba, Japan, has already successfully tried the treatment on 13 patients. The patients showed no sign of recurrence of the disease.
