Quick Answer: What is a chemo port?
A chemo port is a small device placed under the skin of the upper chest, arm or abdomen and connected to a vein by a thin tube. It lets a care team give chemotherapy and fluids and draw blood without repeated needle sticks, and it can stay in place for weeks to years. [1]
What the research says
Ports cause fewer complications than PICC lines in randomized trials. A network meta-analysis of 11 randomized trials with 2,585 people receiving chemotherapy found ports had roughly half the odds of overall complications compared with PICC lines (odds ratio 0.54) and lower odds of clot-related complications (odds ratio 0.37) (Yeow et al., J Vasc Surg Venous Lymphat Disord, 2022).
Ports carry a lower risk of blood clots than PICC lines. Across 22 studies of 11,940 people with cancer, the odds of a catheter-related blood clot in the veins were lower with a port than with a PICC line (odds ratio 0.38) (Wang et al., Thromb Res, 2022).
Most port uses go smoothly, and patients are satisfied. In a prospective study of 149 patients, 91.4% of 1,240 documented port accesses were free of complications, and satisfaction scores met or beat published benchmarks for overall satisfaction, pain and willingness to choose a port again (Werba et al., Langenbecks Arch Surg, 2025).
Key takeaways
A chemo port sits fully under the skin and connects to a vein through a thin, flexible tube.
Placement is a short outpatient surgery — usually about an hour — and you go home the same day.
Chemotherapy can start as soon as the port is in place.
Infection is rare (about 2% of cases), but clots, catheter movement and scarring can happen.
Call your care team right away for severe pain, swelling, redness or drainage around the port.
What is a chemo port?
A chemo port (chemotherapy port) is a small implantable device that sits under the skin and connects to a vein through a thin silicone tube. It is about the size of a U.S. quarter. [1]
It usually goes in the upper chest. It can also go in the arm or abdomen, depending on your situation. [1]
Another common name for it is a "port-a-cath" or implanted port. [1]

What are the parts of a chemo port?
A chemo port has three main parts. Its shape can be round, triangular or oval, depending on the brand. [1]
Part | What it is | What it does |
Port | The main body of the device | The spot where the care team injects fluids |
Septum | The center of the port, made of self-sealing rubber | Lets a needle pass in, then seals itself closed |
Catheter | A thin, flexible tube | Carries fluids from the port into your vein |
What types of chemo ports are there?
There are two main types of chemo ports: single lumen and double lumen. [1]
Type | Access points | Notes |
Single lumen port | One | The most common type |
Double lumen port | Two | A needle can be placed in each access point |
How does a chemo port work?
A chemo port works by giving your care team a ready-made entry point into a vein. They insert a needle through your skin and into the port's rubbery center (the septum). [1]
Through that needle, they can:
Draw blood for tests
Give fluids
Give medicines, including chemotherapy
Who needs a chemo port?
A chemo port is used by many people who need frequent medical care, especially those going through cancer treatment. [1]
It cuts down the number of needle sticks needed for blood draws, infusions and injections. That can make chemotherapy safer and a little more comfortable. [1]
Your oncologist can tell you whether a port is right for your treatment plan.
What happens during chemo port placement?
Chemo port placement is a minor surgery that usually takes about an hour. You go home the same day, but you should have a trusted friend or family member drive you. [1]
During the procedure, your medical team will: [1]
Give you anesthesia to numb the area and keep you comfortable.
Make a small cut in the neck to reach a vein (usually the jugular vein, subclavian vein or superior vena cava).
Make a small opening in the vein for the catheter.
Make a second small cut and create a pocket under the skin of the chest, arm or abdomen.
Place the port in that pocket.
Thread the catheter from the port to the vein.
Close the cuts with stitches.
The surgeon uses continuous X-ray imaging (fluoroscopy) to guide the procedure. A chest X-ray afterward confirms the port is in the right spot. [1]

Is chemo port placement major surgery?
No, chemo port placement is not major surgery. The cut is usually about an inch long, and it is most often an outpatient procedure. [1]
What are the benefits of a chemo port?
The main benefit of a chemo port is easier, safer access to a vein for treatment. [1]
Benefit | What it means for you |
More comfort | You'll usually feel pressure — but little to no pain — when the needle goes in. |
Less risk of tissue damage | Fluids go straight into a large vein, which lowers the risk of chemotherapy leaking into nearby tissue (extravasation). |
Convenience | Once healed, the port is fully covered by skin, so you can swim and bathe without a higher risk of infection. |
Compared with treatment through a standard IV line, a port makes blood draws, infusions and injections much more tolerable. [1]

What are the risks of a chemo port?
The risks of a chemo port come from it being a surgical device that stays in the body. [1]
Risk | What happens | Notes |
Thrombosis (blood clot) | A clot blocks the catheter | See our guide to deep vein thrombosis |
Movement limits | Too much strenuous movement can shift the port | Your surgeon may advise avoiding strenuous activity |
Mechanical problems | The catheter can move out of place and stop working properly | May need adjustment |
Scarring | A small scar usually forms | Expected after surgery |
Infection | Rare — about 2% of cases | Signs: fever, pain and inflammation; the port may need replacing |

What is recovery like after chemo port placement?
Recovery after chemo port placement is usually quick. Most people have mild pain or soreness around the cuts for the first couple of days. [1]

When can you go back to normal activities after chemo port placement?
You can go back to most normal activities right away. Ask your care team before going back to the gym, because too much strenuous activity can shift the port. [1]
When can you start chemotherapy after port placement?
You can start chemotherapy as soon as the port is in place. [1]
Can you shower with a chemo port?
Yes, you can shower with a chemo port 24 to 48 hours after the procedure, if your care team says it's OK. Cover the surgical site with plastic wrap so it stays dry. [1]
Once you've healed, you can shower, bathe or even swim. [1]
How should you sleep with a chemo port?
The best sleeping position with a chemo port is on your back, because it puts the least pressure on the port. [1]
Side sleeping: Fine — sleep on the side opposite the port (port on the right, sleep on the left).
Stomach sleeping: Avoid it, especially while healing, as it can increase soreness.
Arms above your head: Avoid this position, as it adds unnecessary pressure.
No sleep position is dangerous — the goal is simply to avoid pressing on the port. [1]
How long can a chemo port stay in, and how is it removed?
A chemo port can stay in for as long as you need it, even several years. Your surgeon removes it when you no longer need it. [1]
Removal steps: [1]
The surgeon makes a small cut over the port.
They free the port from the surrounding tissue.
They remove the whole device at once.
They close the cut with stitches.
Mild discomfort, swelling and bruising after removal are normal and fade within a few days. [1]
When should you call a doctor about a chemo port?
You should call your care team right away if you have a chemo port and notice any of these: [1]
Severe pain, swelling or bruising around the port
Redness or skin discoloration around the port
Drainage coming out of the port
Fever, pain and inflammation (possible signs of infection)

Conclusion
A chemo port is a small device under the skin that gives your care team easy access to a vein. It means fewer needle sticks, less risk of tissue damage from chemotherapy and more freedom in daily life — including bathing and swimming once healed.
Placement is a short, same-day procedure, and treatment can start right away. Problems like clots, catheter movement and infection are possible, so knowing the warning signs matters.
