“Your condition is chronic but stable.” “The biopsy was benign.” “That’s a contraindication.” “We’re ordering a diagnostic test.”
Healthcare conversations can sometimes sound like another language, even when you recognize every word. And when you’re already worried about a diagnosis, waiting for test results, or trying to remember everything your doctor is telling you, unfamiliar medical words can make the conversation even harder to follow. You’re not expected to know every medical term. In fact, MedlinePlus created its Understanding Medical Words resource because medical terminology can make health information harder for patients to understand.
For Black patients, understanding the conversation can be another tool to help you speak up about your health. But this isn’t about expecting you to become your own doctor. It’s about knowing when to stop the conversation and ask: “What does that mean for me?”
Here are 10 common medical terms worth knowing.
In plain English: Something that starts suddenly or lasts a short time.
“Acute” can sound scary, but it doesn’t automatically mean dangerous. Doctors often use the word to describe how quickly something started or how long it’s expected to last. For example, you might hear acute back pain, acute bronchitis, or acute injury.
Everyday example: You wake up with sudden severe pain in your ankle after injuring it the night before. Your doctor may describe that as acute pain. That’s different from ankle pain you’ve experienced regularly for several years.
A good question to ask: “Is this expected to go away, or could it turn into an ongoing problem?” Also ask what symptoms should make you return for another evaluation.
In plain English: A condition that lasts a long time or needs ongoing medical care.
Chronic doesn’t automatically mean severe. You can have a chronic condition that is well controlled. High blood pressure, asthma, diabetes, arthritis, and multiple sclerosis are examples of conditions that may be chronic. The CDC defines chronic diseases as conditions that generally last a year or more and require ongoing medical attention, limit everyday activities, or both.
You may also hear: “Your condition is chronic but stable.” That usually means the condition is still present, but it isn’t getting significantly worse right now.
Everyday example: You’ve had high blood pressure for five years. Medication keeps it controlled, but you still need regular checkups.
A good question to ask: “What does managing this condition long-term look like for me?” Ask whether you’ll need medication, testing, lifestyle changes, or regular follow-up visits.

In plain English: Not cancerous.
If you’re waiting for biopsy results, this word can be very important. The National Cancer Institute explains that benign tumors are not cancer. Unlike cancerous tumors, they don’t spread into nearby tissues or to distant parts of the body. But benign doesn’t always mean: “Nothing else needs to happen.” A noncancerous growth may still cause pain, bleeding, pressure, or other symptoms depending on its size and location. Some benign findings may also need to be watched over time.
Everyday example: You have a lump biopsied, and your doctor tells you the results are benign. That’s good news. But you still need to know whether the lump requires follow-up.
A good question to ask: “It’s benign, but does it still need treatment or monitoring?”
In plain English: Cancerous.
A malignant tumor contains cancer cells and may grow into nearby tissue or spread to other parts of the body. The National Cancer Institute explains the differences between benign and malignant tumors. Hearing the word “malignant” can understandably be frightening. But it doesn’t tell you everything that will happen. Your healthcare team may still need information about the type of cancer, stage, grade, location, and whether it has spread before discussing treatment.
Everyday example: A biopsy shows that a breast lump is malignant. Your doctor recommends additional tests to learn more about the cancer before creating a treatment plan.
A good question to ask: “What do we know about this cancer so far, and what do we still need to find out?” You can also ask what tests are needed next and how soon you need to make treatment decisions.

In plain English: The signs and symptoms of a disease have decreased or disappeared.
You’ll often hear this word when people talk about cancer. But remission doesn’t always mean cured. According to the National Cancer Institute, partial remission means cancer signs and symptoms have decreased. Complete remission means the signs and symptoms have disappeared, although cancer cells may still remain in the body. That’s why someone in remission may continue having follow-up appointments, scans, bloodwork, or other monitoring.
Everyday example: You finish cancer treatment, and your doctor tells you there’s currently no detectable sign of the cancer. You may be in complete remission, but your healthcare team still recommends regular follow-up visits.
A good question to ask: “What does remission mean in my case, and what follow-up care will I need?”
In plain English: Something that may increase your chance of developing a health problem.
A risk factor isn’t a guarantee. Having a risk factor for heart disease doesn’t mean you’re definitely going to develop heart disease. The National Institutes of Health explains that health risks reflect the chance that something could affect your health. Your risk may be affected by your age, family history, genetics, environment, existing medical conditions, and everyday habits. Some risk factors can be changed. Others can’t.
Everyday example: Your mother and sister both developed type 2 diabetes. Your family history may increase your risk, but it doesn’t mean you’ll definitely develop diabetes too.
A good question to ask: “You said I’m at increased risk. What does that mean for me personally?” Then ask: “Is there anything I can do to lower my risk?” You can also ask whether your risk means you should begin certain health screenings earlier.
In plain English: A reason a medicine, test, procedure, or treatment may not be safe for you.
It’s a complicated word for a fairly simple idea. According to MedlinePlus, a contraindication is a situation where a medication, procedure, or surgery shouldn’t be used because it may cause harm. Sometimes you should avoid treatment completely. In other situations, your doctor may carefully consider the possible risks and benefits.
Everyday example: You ask your doctor about a medication you’ve seen advertised. Your doctor explains that because of another medication you’re taking, this particular drug wouldn’t be safe for you. That’s a contraindication.
A good question to ask: “Why isn’t this treatment recommended for me, and what are my other options?” Make sure your healthcare team knows about everything you’re taking, including prescriptions, over-the-counter medicines, vitamins, herbs, and supplements.
These terms sound similar, but they’re not exactly the same. A side effect is an additional effect that may happen when you take a medication or receive a treatment. An adverse event is a medical problem that happens while someone is using a drug or medical product. The FDA explains that an adverse event report doesn’t necessarily mean a medication caused the event.
Everyday example: You start a medication that’s known to commonly cause nausea, and you begin feeling nauseated. Your doctor may consider nausea a side effect. If another medical problem happens while you’re taking the medication, it may be reported as an adverse event while experts look at whether the medication may have been involved.
A good question to ask: “Which side effects are common, and which symptoms should make me call you right away?” Also ask what you should do if side effects become difficult to manage. Unless you’re experiencing an emergency, don’t stop an important prescription medication on your own without talking with your healthcare professional.
This difference is important. A screening test looks for signs that you might have a condition, sometimes before you have symptoms. A diagnostic test helps determine whether you actually have a particular condition. That means an abnormal screening result isn’t automatically a diagnosis. For example, the National Cancer Institute explains that cancer screening tests look for cancer before someone has symptoms. An abnormal result may lead to additional testing.
Everyday example: You have a routine screening mammogram and something unusual appears. That doesn’t automatically mean you have breast cancer. Your healthcare team may recommend another mammogram, ultrasound, MRI, or biopsy to learn more.
A good question to ask: “Is this test looking for a possible problem, or will it actually diagnose the condition?” If it’s a screening test, follow with: “What happens if the result is abnormal?”
In plain English: What healthcare professionals expect may happen with your condition over time.
The National Cancer Institute defines prognosis as the likely course or outcome of a disease, including the likelihood of recovery and the possibility of recurrence.
A prognosis isn’t always a prediction of exactly what will happen to you. Doctors often base it partly on information from people with similar conditions. Your age, overall health, stage of disease, treatment options, response to treatment, and other factors may affect your personal outcome.
Everyday example: After being diagnosed with a serious condition, your doctor explains how people with your condition usually respond to treatment and what recovery may look like. That’s a discussion about prognosis.
A good question to ask: “What is my prognosis, and what factors could make my outcome better or worse?” If your doctor gives you percentages or statistics, ask: “What does that number actually mean for someone like me?”
Sometimes the most useful medical phrase isn’t a medical term. It’s: “I don’t understand what that means.” You can also say:
Another useful tool is something called teach-back. After your doctor explains something, put it into your own words. For example:
“So, just to make sure I understand, the biopsy was benign, which means it isn’t cancer. But you still want me to come back in six months to make sure it hasn’t changed. Is that right?”
This gives your healthcare professional a chance to correct anything you misunderstood. The AHRQ describes teach-back as a way healthcare professionals can confirm they’ve explained medical information clearly. You can use the same idea as a patient.
Medical information can be harder to remember when you’re nervous, sick, in pain, or receiving unexpected news. Before leaving an appointment, make sure you understand:
If you don’t know the answers, ask. You can take notes on your phone, bring a notebook, or ask for written instructions. If you’re receiving a serious diagnosis or complicated treatment plan, consider bringing someone you trust to listen and take notes when possible.
You don’t need to memorize a medical dictionary. And knowing these 10 terms doesn’t mean you’re expected to diagnose yourself. The goal is much simpler. When someone says your condition is chronic, you should know to ask what long-term management involves. When a biopsy is benign, you should know to ask whether it still needs monitoring. When you’re told something is a risk factor, you should know that risk doesn’t mean a diagnosis. When a treatment is contraindicated, you should know to ask why and what your alternatives are. And when your doctor discusses your prognosis, you should feel comfortable asking what that means specifically for you.
Black patients shouldn’t have to become medical experts to receive understandable healthcare. If a word doesn’t make sense, stop the conversation. Ask: “What does that mean for me?” You deserve an answer you can actually understand.
