Worrieddaughter, your mom is Stage IV, which means she's going to need a reliable, low-maintenance infection-free access line for chemo, blood draws, scans, etc., for a long time.
If I were her, I'd tell her doc that "I want a port, schedule it now!" Just because it's there doesn't mean that a PICC line is intended to be in place for a whole year. Yes, I know it happens. IMNSHO, it shouldn't.
She'd be able to have much more freedom of activity with a port (which is a completely closed system that is accessed by a needle stick.)
If she's tired of her PICC line, there's no reason she needs to keep it. A port surgery is in/out surgery that takes less than half a day. If she's currently on Avastin, that needs to be held for a minimum of four weeks, but her other chemos can continue and they can do a port insertion on an off-week. They'd have to do the same thing if the PICC clogged.
Be in harmony with your expectations.
