Colorectal cancer is the second leading cause of cancer-related deaths in the US. It is also the fourth most common cancer overall. The scarier part? Rates are nearly doubling among young people compared to where they were in 1995.
Most people brush off the early warning signs. Fatigue, constipation, or a bit of diarrhea. They think it is just a food sensitivity, IBS, or a bad piece of takeout. It is easy to ignore things that feel mundane, but that is a mistake.
Prevention and early catches save lives. That is where the “embarrassing” stuff comes in.
Understanding bowel leakage as a potential sign of colorectal cancer
We need to talk about fecal incontinence. It is not the most common symptom, but it is one that doctors want you to notice. If you are experiencing bowel leakage, you might be tempted to keep it quiet. Don’t.
According to Dr. Jason B. Carter and Dr. Ketan Thanki, there are a few reasons why rectal or colon cancers cause this:
- The tumor may shrink the rectum, making it unable to sense when stool actually arrives.
- Cancer can damage the nerves controlling the anal sphincter, so you physically cannot hold it in.
- Some tumors secrete massive amounts of mucus. This leads to diarrhea, which leaks more easily than solid stool.
- A tumor can narrow the colon. Solid waste gets blocked, but pressurized liquid stool squeezes past the obstruction.
Fecal incontinence often presents later in the disease course because an obstruction usually happens once a lesion is large enough to physically block the passage of formed stool.
That means by the time leakage happens, the cancer might be more advanced. But hold on- it does not automatically mean you have cancer. Aging, pelvic floor dysfunction, childbirth injuries, and IBS are way more common culprits.
Which other symptoms indicate colorectal cancer?
Leakage usually is not the first red flag. You will likely see these things first:
- Rectal bleeding or blood in the stool
- New or persistent constipation/diarrhea
- Pencil-thin stools or a change in the size of the waste
- Abdominal pain
- Unexplained weight loss
- Heavy fatigue or iron-deficiency anemia
- Feeling like you are not “done” after a bowel movement
The real trap? You can have colorectal cancer and feel totally fine. Some tumors, specifically those on the right side of the colon, cause zero bowel changes. They only show up as fatigue or weight loss. Which is why screening starts at age 45 for everyone, even the healthy people.
How to reduce your risk and treat colorectal cancer
Can you prevent it? To an extent, yes.
Doctors recommend cutting back on processed foods and red meat while upping your fiber intake. Quit tobacco. Limit alcohol. Move your body. If your family tree has a history of the disease, colonoscopies are your best defense.
If you are diagnosed, there is actually a lot of hope. We have more treatment options now than ever.
- Surgical removal works best if the cancer is caught early.
- Chemotherapy, radiation, and immunotherapies are used if the cancer has spread or is more advanced.
Usually, doctors mix and match these based on the specific patient.
When to make an appointment
Stop guessing. If your digestion feels “off” for a few weeks, get to a clinic. It might be something minor, or it could be a treatable condition that will only get worse if ignored.
Is it worth the awkward conversation with a doctor? Absolutely. Early detection is the difference between a curative procedure and a fight for survival.
