Showering and swimming with an implanted port

Call 911 if you feel very unwell in a way that frightens you — for example you cannot catch your breath, or you feel faint and cannot stay upright. A port problem can turn into a bloodstream infection, and that is not something to wait out at home.

Call your care team right away if you have a fever over 100.4°F (38.0°C), if the port site is red or has red streaks around it, if it is swollen or warm, if yellow or green drainage is coming from it, if you have pain or discomfort at the site, if the port seems to have moved, or if the port cannot be accessed with the special needle. MedlinePlus lists each of these as a reason to contact your provider.

If you are in a chemotherapy cycle, treat the fever differently from the rest of that list. Chemotherapy can leave you without enough white cells to contain an infection, so CDC describes a fever during chemotherapy as a medical emergency — head for an emergency department rather than waiting on a call back. The call-right-away advice above still fits if your treatment does not lower your blood counts, or if you have not started chemotherapy yet.

Most people worry about this before anyone explains it. Here is what MedlinePlus actually says: "When your port is not being used, you can bathe or swim, as long as your provider says you are ready for activity."

Two halves matter equally there. The first half is about the port itself — a port that is not accessed sits fully under the skin, so water is not touching the device. The second half is about you. Your provider decides when the surgical site has healed enough for you to be back in water. That is a personal judgment about your skin, not a rule printed on a card.

So the honest answer to "can I swim?" is: probably yes eventually, and your provider is the one who says when.

Treatment days are different. When the port is accessed, a needle goes through the skin into the device, and MedlinePlus says a sterile dressing is placed around the port to lower infection risk.

That dressing is the thing you are protecting. A needle and dressing in place is not the moment to be submerged in a pool or a lake. If you are unsure whether your port is currently accessed — for example if you are wearing an infusion pump between visits — treat the answer as no and ask the nurse.

When in doubt, ask whether your port is accessed today. That single question answers most of the water questions.

MedlinePlus advises checking with your provider if you plan to do any contact sports, such as soccer and football. The reason is straightforward: the port is a solid object sitting just below the skin, usually on the chest, and a hard impact to that spot is worth discussing before it happens rather than after.

This is a conversation, not a ban. Different people have ports in different places and different reasons for needing them.

Ports are not only for the weeks you are in treatment. MedlinePlus notes that about once a month you will need to have your port flushed to help prevent clots.

Flushing is quick and it happens in clinic. It matters because a port that clots off may not be usable when you need it, and getting it working again is a bigger job than keeping it clear was. If you have gaps between treatment cycles, make sure someone has actually booked the flush rather than assuming it is on a list somewhere.

It helps to know your own baseline. Look at the site while it is well, so you have something to compare against later. Healthy is: skin that looks like the skin around it, no warmth, no streaks, nothing leaking.

If you see redness, red streaks, swelling, warmth, or yellow or green drainage — or if the site hurts — that is the list MedlinePlus tells people to call about. Do not talk yourself out of calling because it seems minor. Port problems are one of the few things in cancer care where calling early is genuinely easier than calling late.
