A worthwhile research IMHO. I have completed survey.

At DDRC Healthcare, and as part of our continuing Health of Divers project, we would like to gain a better insight into cancer and diving. Research shows that physical activity may have beneficial effects for several aspects of cancer survivorship, and at DDRC Healthcare we would like to try and find out a little more about how divers, who have had or currently have cancer, view the sport of diving - has diving helped in your recovery, have you continued to dive, did you give up diving due to cancer?
