Hello!
Mine is on my right side and I am right handed. I appreciate it there because the seatbelt does not bother it! I drive a lot for my job so this is a plus.

As far as surgeries go, having the chemo port installed was pretty minor. It was tender for a couple of weeks, but nothing compared to mastectomies and lumpectomies. I had my port installed on a Friday and started chemo the following Monday. The chemo port may restrict your arm movements a bit on whichever side of your chest it is installed. When mine was installed I was told they typically like to install it on the right side. I told them NO, that I wanted it installed on the left side because I am right handed and already had a lot of range of motion issues from multiple surgeries on my right side. I am so glad I didn't let them put it on the right side. When I was done with chemo the first time they wanted to remove my port, but I insisted on keeping it because it's virtually impossible and very painful to get an IV in either of my arms. It's made life so much easier to have the port access for blood tests, PET scans, surgeries, etc. and when I had to have chemo again a couple of years later I didn't need to go through port surgery for a second time. Good luck with your port installation ❤️

The seatbelt is the one negative about the port being on the left side. I use a large binder clip as a stopper of sorts on the seatbelt up by where it retracts to give it a couple extra inches of space so it doesn't rub on the port and that takes care of the problem. I do this as a driver and as a passenger since the seatbelt irritates the port when I drive and the carnage that used to be my right breast/chest area when I'm a passenger.
