Exercise

2010 I was diagnosed with stage IV anal cancer. after an extensive treatment plan of 7 weeks of radiation and chemo (bag attached to a port that was inserted in my chest) I am working very hard to beat this disease. Healthy eating and walking. I would like to join a gym and try some classes, swimming, exercises, etc. I feel it is essential to build a good immune system to beat this disease. my concern is my port. does anyone with this cancer partipate in exercise that still have their port. what type of exericses do you do, etc. concerns,feedback, comments would be appreciated. i talked to my dr. he see's no problem except for heavy lifting that would tear my stiches that are holding my port in place.
