My mum was diagnosed with breast cancer metastases in her lungs over 2 years ago. She has been treated with letrozole since then and the good news is her condition is staying relatively stable. Having read lots in the press about CBD oil, she is thinking of using that too. Her consultant was very dismissive of it it so I am interested to hear if anyone else has used it at the same time as letrozole and if they think it has helped them.
