STAT means now. Everything else means consult a specialist.
A statistical measure epidemiologists use to describe how many people in a population have a disease at any given time, turning human suffering into percentages since forever. It's different from incidence (new cases) but gets confused with it constantly, even by people who should know better. Think of it as a disease's market share in the population.
The collective term for all plant life in a given area, because apparently calling it 'plants' wasn't scientific enough. Botanists use this when they want to sound sophisticated about cataloging weeds, trees, and that suspicious mushroom growing in your basement. Also applies to the microorganisms living in your gut, which is both fascinating and slightly horrifying.
Double vision where a single object appears as two separate images. Your visual system's version of 'seeing double,' minus the alcohol but with all the concern.
Coughing up blood or blood-stained mucus from the respiratory tract. Your lungs' way of waving a very red flag that something's definitely wrong.
The spread of cancer cells from the original tumor to distant body sites via blood or lymph. When cancer decides one location isn't enough and goes on a hostile takeover tour.
A substance used to dilute or thin out another material, typically a solvent that makes concentrated solutions more manageable for testing or application. In lab settings, it's the boring liquid that turns your scary-strong sample into something that won't melt the equipment. Think of it as the mixer in your chemistry cocktail, except without the fun hangover.
Electromagnetic radiation with wavelengths short enough to penetrate your flesh and expose your bones on film, or the image produced by this process. It's how doctors confirm fractures without invasive surgery and how airport security sees your contraband. The hyphenated version is technically correct, though nobody actually writes it that way.
Programmed cell death; cells literally committing suicide when they're supposed to. Nature's way of saying 'your time is up.'
Having a disease or condition without showing any symptoms. The medical equivalent of finding out your house is on fire after the fact.
A colorless, odorless gas (symbol O) that literally keeps you alive—the universe's most essential freelancer. Your body burns through roughly 550 liters per day, and you don't even have to think about it.
Severe weight loss and muscle wasting seen in advanced disease, particularly cancer. The body's scorched-earth policy when illness takes control.
The process of stopping bleeding, whether through clotting or medical intervention. Your body's emergency repair team that patches leaks before you run out of the red stuff.
Any abnormal tissue damage or wound, from tiny skin spots to massive organ damage. Medicine's vaguest term, conveniently covering everything from 'weird bump' to 'catastrophic injury.'
When your cells get a little too enthusiastic about multiplying and create more of themselves than necessary, making tissues or organs larger through sheer cellular overachievement. Unlike hypertrophy (where cells just get bigger), hyperplasia is about quantity over quality—your body cranking out extra cells like a factory that lost the memo about production limits. It's not always cancer, but it's definitely something your doctor wants to keep an eye on.
A filtration process using membranes with tiny pores to separate small molecules from large ones—essentially a molecular bouncer that only lets the small stuff through. Used in everything from kidney dialysis to water purification, it's like a very selective coffee filter for liquids. The 'ultra' part just means the pores are really, really small.
High blood pressure—the silent killer that's slowly destroying your blood vessels while you feel perfectly fine. The reason doctors get excited about numbers that mean nothing to normal humans.
Intravenous—anything delivered directly into a vein, providing the express lane to your bloodstream that bypasses all that tedious digestion. The method that makes drugs work faster and nurses' jobs more needle-filled.
In medical speak, a specific reason or symptom that justifies prescribing a particular treatment or medication—basically the doctor's permission slip for intervention. It's the clinical justification that separates appropriate medical care from malpractice lawsuits. Insurance companies love scrutinizing indications to deny claims, making this term more powerful than it sounds.
Medical slang for an IV (intravenous) infusion that delivers fluids, medications, or nutrients directly into your bloodstream one drop at a time. It's the hospital's way of keeping you hydrated, medicated, or fed when your body's normal intake methods aren't cutting it. Also recently co-opted by Gen-Z to mean having great style, proving medical terminology can have a glow-up too.
The medical community's polite way of saying "cancer that means business," specifically referring to tumors that have gone rogue and decided to invade neighboring tissues like a hostile takeover. Unlike its chill cousin "benign," malignancy is the diagnosis nobody wants to hear at their doctor's appointment. It's basically the evil twin in the tumor world, capable of spreading and causing serious harm.
The surgical specialty focused on operating on the brain, spine, and nervous system—basically the medical field where millimeter-level precision meets life-altering consequences. It's what separates brilliant surgeons from merely competent ones, requiring steady hands, spatial reasoning, and the ability to remain calm while literally holding someone's consciousness. Also known as the specialty where everyone asks 'but what if you sneeze?'
Having the ability to move spontaneously and independently, like bacteria with flagella or that coworker who can't sit still during meetings. In biology, this describes organisms or cells capable of self-propulsion. Ironically, it also refers to people whose mental imagery is all about movement and action, which explains why some folks can't think without pacing.
The medical equivalent of Google Maps for your cardiovascular system, using X-rays and contrast dye to create detailed roadmaps of your blood vessels and heart chambers. This imaging technique lets doctors play detective, hunting for blockages, aneurysms, or other vascular drama. It's essentially giving your circulatory system its close-up, whether it wants one or not.
The individuals on the receiving end of healthcare services who are expected to be patient (hence the name) while waiting hours past their appointment time. In medical jargon, they're the humans whose symptoms, insurance coverage, and Google-assisted self-diagnoses keep the healthcare industry running. They're called patients rather than customers because 'customer' implies a choice and reasonable pricing.
