Hi
Sascha - Do you live outside the UK? In the UK dairy cows are not routinely given any hormones. Also, there are many different systems for producing milk and keeping dairy cows, so it might be considered a bit of a sweeping statement to say that they are all cruel. Again, in the UK, many of the systems used to keep milking goats and sheep are similar to those used to keep dairy cows.
If your viewpoint is that it is unacceptable to use animals or animal products for food, fair enough. Otherwise I would tend to agree with Lydia.
Having said that, as Revcat ably points out, it's about making choices that you personally are comfortable with and can live with whatever the outcome.
Kate - and everyone else.
I have two strongly held views.
1. STOP FEELING GUILTY! No one thing you did, or did not do, gave you breast cancer. No one thing will stop you from getting it again.
2. Life is a risk sport. Having a glass or three of wine may increase my risk of getting breast cancer again, So what?! I ride horses and so greatly increase my risk of suffering severe head injury every time I get on one. I drive on busy and dangerous roads - sometimes just for pleasure! We all have different attitudes to risk in different areas of our lives.
By all means, lose weight, eat more fruit and veg, give up alcohol - it will have all sorts of health benefits - but you might still get cancer again. There are no guarantees and no simple cause and effect.
It does take a bit of time to put it all into perspective, but if the feelings of guilt persist - or if fear of recurrance starts affecting your ability to get on and enjoy your life, do seek help. A few chats with a suitable counsellor/professional may help you come to terms with it all.
Good luck!
