My oncologist is in France and huge on prevention. Not only a whole range of test every time I am back in Europe, but also dietary recommendations.
Alcohol a massive no and you are having two drinks every weekend (or 4 if 2 every day of weekend) ;
Processed meat another massive no. You are right 12 gr is not a lot, but 12 gr every day when they are a class one carcinogen and we shouldn't exceed 50gr a week.
Red meat is a blunt " just don't " and if I really want it, my oncologist allows me my bodyweight converted in gr once a fortnight. As an example, if you are 60kg it would mean 60 gr every 2 weeks. You are eating little less than 1kg a week? 300 gr how many times per week , 3?
I live in Australia, and my oncologist here is like yours. No wonder, because they follow the UK guidelines. However, UK has one of the worst survival and early detection when it comes to cancer and when you see how people eat here, dietary recommendations are definitely not the country's forte.
Even if your current investigation turns out to be nothing, take this as a warning. Something then goes beyond your weightloss . Nobody is getting younger, and some food might not work for you, be it inflammation, bloating or cancer prevention.
