How to prepare for getting a chest port for chemo?

Hi All,

my sister in law was just diagnosed with stage 3 colorectal cancer and will be getting a port placed for chemo soon. Looking for tips/info to help her prepare. She is very exhausted and in a lot of pain and so I am doing a lot of the research for her. Will she be sore after it is placed? should she wear something that buttons/zips so she doesn't have to raise her arms while it heals? When it comes to going to chemo treatments, any tips on clothing to wear to easily access the port?

Thanks in advance!
