The port is under the skin and requires no cleaning. It essentially is worry free, only the nurse will clean it before she puts the needle in. You may be prescribed lidocaine that is a numbing cream. In case you do not like needles. Once the needle is in, you rarely if ever feel it in use. Amazing compared to needle sticks. I was a platelet donor stuck by a needle every 3 weeks or less for 25 years.
A port was a delight. Take a shower as you always do. A port put in correctly will not be an issue.
The port for me was above the breast area, just above the chest on my right side. I can barely see where it had been, and mine was removed March 31, 2023. A reminder of the engineer who created a port for us.
