Alcohol is a Group 1 Carcinogen (cancer causing to humans). It is a risk factor for getting breast cancer (and other cancers and health issues) in the first place. I used to drink but personally have made the choice to not drink alcohol at all post bc. There is no nutritional benefit to alcohol. I can relax and enjoy myself without it.
Regardless of the finer points of any research as to whether it increases the risk of recurrence it makes sense to me that this is not something I want to worry about. I have gone through far more difficult things in order to reduce my risk of recurrence than giving up alcohol. Life is just fine without it.
But I do feel very much in the minority with this decision which is sometimes upsetting. I have received so much support for other lifestyle changes I have made but people are strangely silent when it comes to my choosing to reduce my risk of recurrence by not drinking. ??
