@Yoddleman  It can be quite a shock when there is a diagnosis of a life threatening condition especially when communication has not been optimal.   When a tumour is small a patient can present with mild symptoms and these increase as the tumour grows and are variable from patient to patient, certainly the neurologist sending your grandpa to the hospital for further investigations was wise. Having the scans and any blood test results with you when you return to see the neurologist will help them to give you a further opinion with the additional information now available.   In relation to medical imaging, radiologists frequently use the terms "suggestive of ..." or "in keeping with ..." as a CT or MRI scan cannot give a definitive diagnosis on a mass lesion although contrast enhancement does help define features such as if the lesion appears cystic or solid etc.  CT and MRI help differentiate the nature of lesions in different ways.   Pathology will give a definitive result.   I am afraid the questions you are asking are well out of the scope of most carers as we are not medically trained and rely on the expertise of doctors on relation to the care of our loved ones. I have found it useful to write down the questions or concerns we have, there are respectful ways to ask for clarification.  I  not sure what the situation is like on Poland, here in Australia a dedicated family member/ primary caregiver with the patients consent is able to attend doctors appointments with them.    Please do continue to reach out for support as the path ahead will likely be emotionally, physically and spiritually draining.  ...
