Welcome to Cancer Chat. This is an excellent question and one which I'm sure that many on this site would like to know the answer to.
I have not had radiotherapy or chemo, so I am afraid that I cannot answer your question. Did you ask your care team? They are usually in the best position to tell you as they have your medical history to hand
You might get a more educated answer from some of the nurses on this site. You can phone them Freephone on 0808 800 4040, or you can post a question in the 'Ask the Nurses' section of this site.
You may also find it useful to use the search engine on the blue banner at the top of this page. Type in alcohol related questions and you should find previous posts on this topic.
