Elekta Neuro-Oncology Series #5: Dr. Arjun Sahgal - Brain Metastasis

Rad Chat

**Trigger Warning**

Naman Julka-Anderson and Jo McNamara catch up with Dr. Arjun Sahgal to discuss his career, and the uses of radiosurgery for brain metastasis.

To use this podcast as CPD, look at these reflection points:

1) read about the symptoms of a brain tumour: https://www.thebraintumourcharity.org/brain-tumour-signs-symptoms/adult-brain-tumour-symptoms/

2) reflect on the benefits of radiosurgery for people diagnosed with brain metastasis.

3) consider the impact of reduced access to radiosurgery could have on a a person living with beyond cancer and their loved ones / carers.

4) watch this video on the Elekta Gamma Knife Radiosurgery: https://www.youtube.com/watch?v=pxikNfTbtzw
