Anxious for mum

Mum was ill in January, a ct scan showed a vast shadow on her lung, this was followed up with another ct 8 weeks later which showed it was highly unlikely to be infection as it had grown so a full body pet ct was ordered. Biopsy not possible due to location. Pet ct was done last Monday. The results were at the mdt meeting today so I’m assuming we will hear over the next few days 

We lost dad after a very brief cancer diagnosis in 2023, at 68, same age mum is now. Mum has been so emotional and I’m worried sick about her. I have 3 siblings and although I’m not the eldest, I’m kind of in charge and in control of everything. 

I am prepared for the worst, but how can I support mum through this?

Many thanks x
