I'm aged 79 and was diagnosed with secondary liver cancer in July after 3 scans. This followed a colon cancer op in November 2022 and 3 months chemo, after which I made a rapid recovery (and achieved over 2,000 miles on my e-bike!). An operation on 16 August removed 3 small tumours and 2 suspicious spots which turned out to be non-cancerous. Since then I've been in recovery mode and gradually increasing the miles walked each week, currently around 15-20, but not yet back on the bike. I'm waiting to hear the results of a scan if chemo is required but at an initial meeting with my oncologist he thought this may be unnecessary.
Despite secondary liver cancer being rated stage 4 it does seem possible to live a near normal life for several years provided it has not progressed too far. If it weren't for the scans I had in the summer, when I felt 100% fit, things could well be different by now, so thank God for scans. I remain positive but time will tell. Best of luck with your diagnosis and any treatment that may be necessary.
