Freezing Out Breast Cancer

Nitrógeno líquido siendo servido en un envase plástico

Cryotherapy, the use of extreme cold, has been used to treat skin cancer for many years.  New results show that cryosurgery may be a good alternative to traditional surgery for some early cases of breast cancer.  

The treatment uses liquid nitrogen filled rods to freeze cancer cells, and can be done in a minimally invasive way. 

How cold is liquid nitrogen? -321o F (-196o C)  Pretty darn cold!!!
