Does advanced cancer always cause severe pain?

No. Advanced cancer does not always bring severe pain. Some people assume that there will always be severe pain with advanced cancer. The National Cancer Institute answers plainly: this does not have to be the case.

Two facts sit behind that, and they need holding together. Pain occurs in 20% to 50% of people with cancer overall, so having cancer does not mean you will have pain at all. But NCI's health-professional pain summary is blunt about the later stages: roughly 80% of patients with advanced-stage cancer have moderate to severe pain. So severe pain is not inevitable, and it is also not rare — the reason it does not have to be your experience is that it can be treated, not that it is unlikely.

When pain does appear, it can usually be controlled with pain medicine and non-drug approaches. People whose pain is managed are able to focus on enjoying life. They sleep better, spend time with family and friends, and keep doing things that matter to them.

Where cancer pain comes from

Pain has more than one source, and the source shapes the treatment.

It may come from the tumor itself, pressing on bone, nerves, or organs. It may come from cancer treatment. Or it may come from a side effect: mouth sores, skin reactions, or peripheral neuropathy, which is nerve damage that causes numbness, tingling, or burning in the hands and feet.

Nerve pain in particular often responds to different medicines than pain from a tumor pressing on bone. Which is why "how bad is it" is not the only question worth answering.

The real obstacle

The most common reason cancer pain goes untreated is that it goes unreported. People hold back to avoid seeming difficult, or because they assume pain is simply part of this, or because they fear what the pain means about the disease.

Fear of addiction stops many people too, and the NCI takes it on directly. It is common for people with cancer to worry about becoming addicted to pain medicines. Needing a higher dose over time, or having symptoms when a dose is lowered or stopped, is not the same as addiction. Those are tolerance and physical dependence, both expected and both manageable by your team.

How to describe pain so it gets treated

Rate it on a scale where 10 is the most pain and 1 is the least. Then add the details a number cannot carry.

• Where it is, and whether it moves.
• What it feels like: aching, sharp, burning, pins and needles.
• When it comes, and what makes it better or worse.
• What it stops you from doing, such as sleeping, walking, or eating.
• What you have taken for it, and how much that helped.

Contact your doctor or nurse if you feel new pain, if your pain is not decreasing with the medicine you have, or if you are having side effects from the pain medicine. All three are reasons to change the plan, not reasons to wait for the next appointment.

Who to ask for

Sometimes a palliative care specialist is the best person to treat pain. Palliative care is comfort-focused care that makes patients feel better without treating the disease itself. It covers symptoms, emotional support, and practical problems.

It is worth clearing up a common confusion. Palliative care runs alongside cancer treatment and can start at any point, including the day you are diagnosed. Hospice is different: it is care given when therapies are no longer controlling the disease.

You can ask for a palliative care referral yourself. Pain is not something you simply have to put up with.
