Health Library / Lifestyle
This content is for education only and is not medical advice. I'm a fitness coach, not a physician. Talk to your doctor before starting any medication, hormone, supplement, or new exercise program, especially if you have a medical condition or take prescriptions.
This is the least fun module in the library and probably the most valuable, so I'll keep it tight.
Everything else here is about being strong and capable into your seventies. None of it matters if something treatable gets found late. Screening is the part of health that has nothing to do with effort or discipline — you just have to book it.
I'm going to explain what each test is. What applies to you, and when, is your doctor's call, because it depends on your family history, your own history and risk factors in ways no article can account for.
The screening start age was lowered to 45 — it used to be 50 — because colorectal cancer has been rising in younger adults. A lot of people over 45 still believe 50 is the number and are running late without knowing it.
Colonoscopy is the thorough one. You're sedated, it takes well under an hour, and the prep is the part everyone complains about — a day of clear liquids and a laxative regimen. Nobody enjoys it. The unique advantage: it both finds and removes precancerous polyps in the same session, which means it prevents cancer rather than just detecting it. No other screening test does that.
Stool-based tests — FIT, and DNA tests like Cologuard — are done at home and are a legitimate option. They're less invasive and repeat more often, and a positive result means you're getting a colonoscopy anyway.
This cancer is highly treatable when caught early and grim when caught late, and the whole point is that early is symptom-free. Waiting for symptoms is the failure mode.
Mammography is the standard, and the guidance on start age and frequency has shifted over time with genuine debate behind it. Dense breast tissue changes what's visible and sometimes prompts additional imaging — many states now require that you be told your density.
Family history changes everything about this conversation, particularly a first-degree relative or a known genetic mutation. Say it out loud to your doctor even if you think it's on file.
PSA is a blood test, and it's the one with the most genuine nuance.
The complication: PSA can be elevated for benign reasons, and some prostate cancers found this way grow so slowly they'd never have caused a problem — so treating them can cause harm without benefit. That's why the official position has moved toward shared decision-making rather than blanket screening: a real conversation about your risk, your age and what you'd do with the result.
Risk is higher for Black men and for men with a family history, and those conversations often start earlier.
Don't skip it because it's complicated. Have the conversation.
Low-dose CT screening exists for people with significant smoking history, and it's underused — a lot of eligible people have never been told they qualify. If you smoked substantially, ask whether you're eligible. This one genuinely saves lives and most people don't know it's available.
Hawaii has a serious melanoma problem. High UV year-round, an outdoor culture, and a lot of people who moved here from somewhere with less sun and never adjusted their habits.
Learn the pattern for what's worth showing someone: asymmetry, irregular border, uneven colour, larger diameter, and — most important — anything changing. A spot that's evolving matters more than a spot that looks unusual and always has.
Also check the places people forget: scalp, ears, the tops of feet, between toes, under nails, and the back, which you need someone else or a mirror for.
Melanoma is very survivable caught early and very dangerous caught late. If you train outside here, a periodic skin check is a reasonable thing to build into your year.
Cervical screening continues into this age bracket on a schedule your doctor sets, and HPV testing has changed how it's done.
Your physician may raise others based on your history — hepatitis C, AAA screening for men with smoking history, bone density, diabetes. This isn't a complete list and it isn't meant to be.
Two patterns cost people, and I've watched both.
"I feel fine." That's what early cancer feels like. That's the entire premise of screening. By the time you feel it, you've lost the advantage the test was offering.
"I'll book it after…" After the holidays, after this project, after the kids' thing. Then it's two years later. If you're behind on something, book it this week — not because something's wrong, but because the booking is the hard part and it takes four minutes.
Fitness doesn't exempt you. Being strong and lean is genuinely protective for several cancers and it is not a substitute for screening. I've known people in excellent shape who got the diagnosis, and the ones who'd kept up with screening did better than the ones who'd been too healthy to bother.
Know your family history. Tell your doctor. Book the appointment.
