Having thought about the posting from JohninKent on the OPA site I am quite happy to explore the idea of arranging a group for those who are not on the post-surgical journey, if coming along to a main OPA meeting won't meet people's needs.
The problem is likely to be one of geography though, and I do not really know where people live!
The ideal place would be a place like Maggie's Centre, but that is in Hammersmith. But perhaps there are other locations that are more suitable, and my guess is that travelling logistics are going to be difficult!
