I had my follow up CT scan on Monday with the intent of checking whether the new 'thing' in my right lung has grown at all. I met Prof. Horwich at the Royal Marsden today and he confirmed that everything seems fine. My AFP tumour marker is still normal and the scan shows no apparent abnormalities in my lungs. They the believe the slight thickening on the edge of the lung picked up on the previous scan is probably scar tissue from my previous surgery - it seems to coincide with the area that I had a drain inserted into the lung.
Panic over! Thanks to all who crossed their fingers...again!!
