What Is SBRT?
SBRT or stereotactic body radiotherapy is a very precise treatment done by using a computer to direct several radiation beams to a cancer tumour from different angles. The radiation dose of this treatment is higher than the standard radiation therapy and is more accurate in hitting the right spot, therefore, reducing the chances of harming the nearby, healthy tissues. It is recommended to patients with certain kinds of cancer, such as lung cancer.
How does it work?
The radiation of SBRT treatment damages the DNA of cancer cells, preventing them from growing and dividing. Eventually, the cancer cells die and the tumour gets smaller, says Dr Sayan Paul, the best lung SBRT specialist in kolkata.
