My mum is in her early 70s and has recently lost a significant amount of weight. She has been feeling more tired than usual for quite a while and complains of lower back and leg pain (she was previously under Rheumatology for arthritis, so could be a flare up), but other than that, no specific symptoms like loss of appetite or abdominal pain. She has had a recurrent cough/cold like symptoms for a few years, but I feel she's not worried about her health, like I am. She has type 2 diabetes and it was the pharmacist at our GP surgery who brought up the weight loss, then booked her in for a telephone call with the GP (which she had today). 

The GP was concerned and is planning to refer her for tests under the 2WW, but has asked her to have blood tests and a FIT test first (she did have a FIT test as part of NHS screening about one month ago, which was negative). Although things are moving along, I'm feeling quite disheartened, as I have been trying to encourage her to take her symptoms more seriously/speak to the GP about them and always offer to speak on her behalf - but she didn't think they were anything to be too concerned about. I'm now worried that it could be cancer and at a late stage, given the weight loss and fatigue. I struggle a lot with anxiety and I'm probably more worried than she is. I know worrying won't solve anything, but I'm already thinking ahead, of 'What if? Then...' scenarios. Would appreciate any advice.
