Chemo in Just as advertised

I know that I haven't written in here lately.

My mom will be having a port put in for chemo on the 20th.

I feel like there is something she doesn't want to tell me.

Like she told me they were pre cancerous cells, and I am now I am getting the feeling it is way more.

I feel like I have the right to know, but am unsure how to ask.

She will be having chemo every two weeks for six months.
