A patient sat across from me recently and said, almost apologetically, "I turned 47 two years ago and I've been ignoring the colonoscopy thing." She isn't unusual. Most people put this one off, not because they don't care, but because it feels awkward, vaguely unpleasant, and easy to postpone for another year.
Here's what I tell them. Colorectal cancer screening is one of the few tests we have that can actually prevent a cancer, not just catch it early. That's worth a slightly uncomfortable afternoon.
When should I start colorectal cancer screening?
For most adults at average risk, screening should begin at age 45. That recommendation moved down from 50 a few years ago because colorectal cancer has been showing up earlier than it used to, including in people who feel completely fine.
If you have a family history of colon cancer or certain polyps, an inflammatory bowel condition, or specific genetic syndromes, you may need to start sooner and screen more often. That's a conversation I'd rather have with you directly than guess at in a blog post. In my practice, I review your personal and family history and build the timeline around you.
What are my options besides a colonoscopy?
You have real choices, and not all of them involve a procedure. Broadly, screening falls into two camps:
- Colonoscopy — a gastroenterologist examines the entire colon and can remove polyps in the same visit. It's the most thorough option, and if it's normal, you typically won't need another for about ten years.
- Stool-based tests — done at home, no prep, no sedation. These look for hidden blood or abnormal DNA in a stool sample. They're repeated more often, and importantly, a positive result always needs a follow-up colonoscopy.
Neither is the "right" answer for everyone. The best test is the one you'll actually do. I've had patients who would never have booked a colonoscopy happily mail in a stool kit, and that test caught something we needed to chase down.
How does Direct Primary Care make screening easier?
The honest answer is that coordination is where most people fall through the cracks, and that's exactly the part I handle. Colorectal cancer screening coordination in my office means I help you pick the right test, place the referral, and make sure results don't vanish into a portal you never check.
If you choose a colonoscopy, I connect you with a trusted gastroenterologist here in Los Angeles, many of them through my Cedars-Sinai network, and I make sure they get your history before you arrive. If you choose a stool test, I order it, walk you through the kit, and circle back when the result comes in.
And if a result comes back abnormal, you won't be left to interpret it alone. I'll call you, explain what it means in plain terms, and arrange the next step.
What if I don't have any symptoms?
That's the whole point of screening, and it's the part people misunderstand most. We screen precisely because early colorectal cancer and pre-cancerous polyps usually cause no symptoms at all. By the time there's bleeding, a change in bowel habits, or unexplained weight loss, we've often lost the easy window.
Waiting to "feel something" is the strategy that costs people the most. Screening when you feel perfectly healthy is the version of this that works.
I think of colorectal screening as part of a larger habit of looking after yourself, alongside the rest of your preventive care. The patients who do best aren't the ones who never get sick. They're the ones who stay a step ahead.
How do I actually get started?
You start by telling someone you're ready, and then letting them carry the logistics. That's genuinely most of the work, and it's the part I take off your plate.
If you're 45 or older and you've been quietly putting this off, I'd love to help you finally check it off. Reach out through my contact page and we'll talk through which screening makes sense for you, no pressure and no judgment. I've never once heard a patient regret getting it done.
