Chemotherapy Ports and Lines: — Which One Do You Actually Need?
When your oncologist mentions a port or a PICC line, it is often the first you have heard of either. They are not the same thing, they do not suit every treatment, and you are allowed to understand what you are agreeing to before anything is inserted.

- Three options, not one — A cannula, PICC line and port each work differently and suit different treatments.
- The drugs decide as much as you do — Some chemotherapy drugs require a central line for safety — your vein type is not the only factor.
- Preference is part of the decision — If both a PICC and a port are medically suitable, your team should explain both and ask what you prefer.

There are three ways to deliver chemotherapy: a cannula (re-inserted each visit), a PICC line (inserted once, stays for weeks to months), and a port (implanted under the skin for the duration of treatment). Your oncologist recommends one based on the drugs planned, how long treatment will run, and the condition of your veins.
What are the three options for delivering chemotherapy into a vein?
A cannula is a short plastic tube placed into a vein in your hand or forearm before each chemotherapy session and removed when the session ends. It suits short courses where the drugs do not require central venous access.
A PICC line (peripherally inserted central catheter) is inserted once into a vein in your upper arm and threaded through to a large vein near the heart. It stays in for weeks to months, which removes the need for a fresh needle at every visit. The external tubing needs to be flushed and the dressing changed regularly.
A port (also called a port-a-cath or implantable port) is a small device placed under the skin on your chest during a minor procedure. A nurse accesses it through the skin with a special needle at each visit. It has no external components when not in use, is not visible under clothing, and is intended for treatments running many months.
What decides which one your oncologist will recommend?
The type of drugs planned is the first factor. Some chemotherapy drugs are classified as vesicants — they cause severe tissue damage if they leak outside a central vein. ASCO and ONS guidance states that vesicant drugs should be given through a central line, not a peripheral cannula. If your regimen includes a vesicant, a PICC or port is a clinical requirement, not a preference.
The length of treatment is the second factor. A cannula re-inserted at every session is manageable for a short course. For many months of treatment, a PICC or port is more practical and protects your veins from repeated puncture.
Your lifestyle also matters. If you swim, work with water, or have a physically demanding job, a PICC line's external tubing can be difficult to manage. A port has no external components between visits. If both are clinically appropriate, your preference is a reasonable part of the conversation — tell your team before you agree to either.

Which signs of infection should you report straight away?
- Redness, warmth or swelling at the entry site or along the armCall your team the same day — do not wait for your next appointment.
- Any discharge or crusting at the insertion pointDo not wait for your next session — call today.
- A fever of any degree alongside any line symptomFever with a central line in place is always a same-day call.
- Pain or tenderness at the site that has increased since your last visitTell your nurse before the next infusion begins.
- Swelling in the arm where your PICC line is placedThis can indicate a clot as well as infection — report it the same day.

Questions people ask before agreeing to a line or port
Can I refuse a port and ask for a PICC line instead?
You can and should discuss this with your oncologist before any procedure is booked. If both options are clinically appropriate for your drugs and treatment length, your preference genuinely matters and your team should present both before you decide. If only one is safe — for example, your veins or anatomy make a PICC impractical, or your drugs require a specific type of access — your oncologist will explain why. You are not required to agree to any procedure without understanding the reason, and a clear explanation is reasonable to ask for.
Does inserting a PICC line or port hurt?
PICC insertion is done under local anaesthetic in a treatment room. Most people feel pressure and a sensation as the line is threaded, rather than pain. Port insertion is a small procedure done under local anaesthetic, usually with some sedation, and takes around 30 to 60 minutes. You are likely to be sore at the site for a few days afterwards. Neither procedure should cause severe pain during or after — if you experience that, tell your team, because pain beyond normal post-procedure soreness is worth reporting promptly.
How do costs compare between a cannula, PICC line and port?
A cannula has no separate insertion cost — it is placed by the nurse at each visit as part of your treatment session. A PICC line involves an insertion procedure and requires regular flushing and dressing changes throughout treatment, which carry their own costs. A port has a higher one-time insertion cost because it involves a minor surgical procedure, but for treatments running many months it may be more economical overall than ongoing PICC maintenance. All costs are indicative and depend on the centre and materials used. Ask your care coordinator for an estimate based on your specific treatment plan, as figures change over time.
Can I shower and swim with a PICC line or port in place?
With a PICC line, the external tubing and site must be kept completely dry. Showering with a waterproof sleeve is usually possible; swimming is not recommended while the line is in place because prolonged immersion raises the risk of infection entering the catheter. With a fully healed port, normal showering is generally possible without special covering because there is no external component between visits. Whether you can return to swimming once the port site has healed depends on your team's guidance — ask specifically, as the answer can vary. Your nurse will explain the dressing routine and what precautions apply.
What happens to my port when treatment ends?
The port can remain in place for a period after treatment finishes, in case further cycles are needed or for follow-up blood draws. When it is no longer needed, it is removed in a brief procedure comparable in complexity to the insertion. Removal is not urgent once treatment is complete — the timing is agreed with your oncologist based on your review schedule. Some people keep their port for a year or more if they are on long-term monitoring. The skin heals fully after removal and leaves a small scar.
How do I know if there is a clot in my line?
Clots can form around PICC lines and port catheters, and they are more common than most people expect. Signs include swelling in the arm on the side of a PICC line, new pain or heaviness in the arm or shoulder, or a line that is suddenly harder to flush than before. A clot does not always cause visible swelling — resistance when flushing is sometimes the first sign. Do not try to force a line that will not flush. Report any of these on the day you notice them; a clot in a central line is treatable, and prompt reporting is what keeps it manageable.
Did you know?
Some chemotherapy drugs cause irreversible tissue damage if they leak outside a central vein into surrounding tissue — a complication called extravasation. For these drugs, a peripheral cannula in the hand or forearm is not considered clinically safe, and a PICC line or port is the standard of care, not an optional upgrade.
If your oncologist has recommended central venous access and you are not sure why, asking which drugs in your regimen are vesicants is a reasonable question.

Frequently asked questions
Is port insertion a surgery, and will I need to stay in hospital?
Port insertion is a minor procedure, usually done under local anaesthetic with sedation, and most people go home the same day. It is performed in a procedure room or minor theatre, not a main operating theatre, and takes around 30 to 60 minutes. You will be sore at the site for a few days and should avoid lifting with that arm while it heals. Your team will tell you what to watch for at home, and any increasing pain, swelling or fever in the days after insertion is worth reporting rather than waiting.
Can my PICC line be used for blood tests as well as chemotherapy?
Yes. A PICC line can generally be used to draw blood for tests as well as to give chemotherapy and fluids, which means fewer needle pricks overall. Whether blood draws are routinely taken through the line depends on your team's protocol and the specific type of PICC placed. Ask your nurse before your first session whether your line will be used for blood tests, so you know what to expect at each visit.
Can I carry on working while I have a PICC line or port?
Many people continue working during chemotherapy with either device. A port has no external components when not in use, which makes it easier to manage at work. A PICC line has external tubing that needs to be secured and kept dry, which can be more awkward if your job is physical or involves water. Tell your team what your work involves before a line is chosen — they may be able to factor this in if both options are medically suitable for your treatment.
What is a power-injectable port and do I need one?
A power-injectable port (sometimes called a power port) is designed to withstand the high pressure used when injecting contrast dye during CT scans, allowing the scan to be done through the port rather than a separate vein. Standard ports are not built for that pressure. Whether you need one depends on how often contrast CT scans are planned as part of your monitoring. If regular contrast imaging is expected, a power-injectable port avoids additional cannulation for those scans. Ask your oncologist which type has been selected for you and why.
How long can a port stay in after chemotherapy finishes?
A port can remain in place safely for months or years after treatment ends if ongoing monitoring or further treatment is planned. It does need to be flushed periodically even when not in active use, to prevent it from blocking — your team will tell you how often. When it is no longer needed, removal is a brief procedure. The timing is decided with your oncologist based on your review schedule and whether more treatment is likely.
Do I need a port or PICC line for immunotherapy as well?
Immunotherapy infusions are often given through a peripheral cannula placed at each visit, because the drugs used are not typically classified as vesicants and the infusions are generally shorter than many chemotherapy sessions. Whether you need central venous access depends on your specific drugs, treatment duration and vein condition. If you are receiving immunotherapy alongside chemotherapy, the central line requirement of the chemotherapy regimen usually determines the access type for the whole combination. Your oncologist will advise based on your complete treatment plan.
