The short answer
This page explains the difference between costochondritis and chest wall pain that needs a cancer workup. It is general education, not individual medical advice.
Costochondritis is a common cause of chest pain, and it is inflammation of rib cartilage, not cancer.
Pain that gets worse when you press on the spot where a rib meets the breastbone points toward costochondritis.
NCI notes that cancer often does not cause pain, so a lack of pain is not proof that all is well either.
Sudden crushing or squeezing chest pain is an emergency; call 911 rather than trying to sort out the cause yourself.

The full explanation.
Pain in the chest wall that flares when you press on it is far more likely to be costochondritis than cancer. Costochondritis is inflammation of the cartilage that connects a rib to the breastbone, and MedlinePlus calls it a common cause of chest pain. Still, chest pain is never a symptom to shrug off, because a few causes are emergencies.
What is costochondritis?
The ribs attach to the breastbone through pieces of cartilage, which is firm, flexible tissue. When that cartilage becomes inflamed, the result is costochondritis.
Often there is no known cause. MedlinePlus lists several possible triggers: an injury to the chest, hard or strenuous exercise, a viral infection, and strain from bouts of coughing. MedlinePlus also names infections after surgery as a possible cause.
The pain has a recognizable pattern.
- It is sharp and felt at the front of the chest wall. It may spread toward the back or belly.
- It gets worse with a deep breath or a cough.
- There is tenderness when you press the spot where the rib joins the breastbone.
- It eases with rest and quiet breathing.
That last exam finding matters. Pressing on the joint and reproducing the pain is how a provider recognizes costochondritis.
How is chest wall pain different from cancer pain?
Cancer pain does not have one single signature, which is why the honest answer starts with context. NCI is direct about it: symptoms like these are most often caused by illness, injury, benign tumors, or other problems. A benign tumor is a growth that is not cancer.
NCI adds a point that cuts the other way. Often, cancer does not cause pain, so do not wait to feel pain before seeing a doctor. In other words, pain is neither proof of cancer nor is its absence proof of health. What NCI asks you to watch is persistence: if a symptom does not get better after a few weeks, see your doctor so problems can be found and treated early.
Costochondritis usually follows the opposite course. MedlinePlus says the pain often goes away in a few days or weeks, though it can take up to a few months. It responds to rest, hot or cold compresses, and over-the-counter pain relievers such as ibuprofen or acetaminophen.
So the practical difference is behavior over time. A tender spot that eases with rest and fades over weeks fits costochondritis. A change that persists, returns, or comes with other unexplained changes deserves a visit. Our page on cancer symptoms covers the changes doctors want to hear about.
What else causes chest pain?
MedlinePlus groups the causes by body system, and most have nothing to do with cancer.
- Heart and blood vessels. Angina or a heart attack, which can feel like tightness, heavy pressure, squeezing, or crushing pain. Also pericarditis, which is inflammation of the sac around the heart.
- Lungs. Pneumonia and pleurisy cause sharp pain that worsens with deep breathing or coughing. A blood clot in the lung or a collapsed lung can cause sudden pain with shortness of breath.
- Digestive system. Heartburn, spasms of the esophagus, gallstones, and stomach ulcers.
- Muscles, bones, and nerves. Costochondritis, strained muscles or tendons, and shingles.
This is why a provider may order a chest x-ray or other tests even when costochondritis seems likely. The point of testing is to rule out the serious causes, not to hunt for cancer in every sore rib.
How is the cause sorted out?
The visit usually starts with an exam. Tenderness when the provider presses where the rib joins the breastbone supports costochondritis. The story matters too: recent coughing fits, new exercise, an injury, or a viral illness all point toward an inflamed joint.
If the pattern does not fit, or if anything suggests the heart or lungs, tests come next. Getting checked is not overreacting. It is how a common, harmless cause gets confirmed. If a symptom still worries you after a normal visit, say so — our guide a symptom is not a diagnosis explains how to ask for a clear follow-up plan.
When to get help sooner
Some chest pain should not wait for a scheduled visit. MedlinePlus gives clear lines.
- Call 911 if you have sudden crushing, squeezing, tightening, or pressure in your chest; pain spreading to the jaw, left arm, or between the shoulder blades; or pain with nausea, dizziness, sweating, a racing heart, or shortness of breath.
- Call 911 if sudden sharp chest pain with shortness of breath starts after a long period of sitting still, which can signal a blood clot.
- Contact your provider promptly if you have a fever or are coughing up yellow-green phlegm, if severe chest pain does not go away, or if any chest pain lasts longer than 3 to 5 days.
- After a costochondritis diagnosis, call back if the pain is getting worse, you develop trouble breathing, or you feel sharp pain with every breath.
And keep NCI's longer clock in mind: any symptom that has not improved after a few weeks has earned an appointment.

Common questions
Is costochondritis a sign of cancer?
No. Costochondritis is inflammation of the cartilage that connects a rib to the breastbone. MedlinePlus lists it among the musculoskeletal causes of chest pain, alongside strained muscles, and says it often has no known cause. It can follow a chest injury, hard exercise, a viral infection, or strain from coughing.
How long does costochondritis last?
MedlinePlus says the pain often goes away in a few days or weeks, though it can take up to a few months to settle fully. Rest, hot or cold compresses, and over-the-counter pain relievers such as ibuprofen or acetaminophen are the usual care. Ask your provider what fits your situation.
When is chest wall pain worth a doctor visit?
NCI's general rule for symptoms is to see your doctor if they do not get better after a few weeks, so problems can be diagnosed and treated as early as possible. For chest pain specifically, MedlinePlus says to contact a provider for severe pain that does not go away, for pain lasting longer than 3 to 5 days, or if you have fever or are coughing up yellow-green phlegm.
Does cancer cause chest pain?
It can, but NCI stresses that symptoms like these are most often caused by illness, injury, benign tumors, or other problems. NCI also notes that cancer often does not cause pain at all, which is why it advises not waiting for pain before getting a persistent change checked.
