My mum has been diagnosed with Oesophageal Cancer

My mum was diagnosed earlier after an endoscopy test, doctors said there were 2x tumours of between 3-5cm.  She has a CT scan booked for next couple of days. Does anyone have experience of how far advanced this is based on tumour size. My mum has already lost a lot of weight so I’m concerned treatment options will be limited due to her overall fitness
