Blood in the stool can also be a warning sign. Sometimes it looks bright red while other times it may make the stool look very dark or black. Do not ignore blood in your stool as it can signal an issue that needs attention right away.
Abdominal pain and cramps are other signs to watch out for. These pains might feel different from normal stomach aches you get now and then. Frequent gas pains, bloating, fullness, or discomfort are also on the list of symptoms.

There are also less invasive tests like the sigmoidoscopy. Similar to a colonoscopy but shorter it examines only part of the colon. While not as thorough as a full colonoscopy it still offers valuable insights into your
bowel health.

What is a colonoscopy?
A colonoscopy is a medical test used to look inside the colon. This test helps doctors find signs of colorectal cancer early. It involves using a long flexible tube with a camera at the end.
Before the test you need to prepare your bowel. This usually means drinking a special solution that cleans out your intestines. It’s important to follow these steps for clear results.

Imaging tests for diagnosis
Imaging tests play a big role in diagnosing colorectal cancer. These tests give detailed pictures of the colon and rectum. One common imaging test is the CT scan also known as a CAT scan.

Another useful test is MRI or magnetic resonance imaging. It uses strong magnets and radio waves to make detailed images of organs and tissues inside you. Unlike CT scans MRIs do not use radiation.
Sometimes doctors also recommend an ultrasound for more focused views of specific areas within the abdomen during diagnostic screenings aimed at detecting potential early signs.

A biopsy is a key procedure for diagnosing colorectal cancer. It involves taking a small tissue sample from the colon or rectum. This sample helps doctors confirm if cancer cells are present.
How Is Colorectal Cancer Diagnosed? During a colonoscopy, if the doctor sees something unusual, they may take a biopsy right then. A special tool is used to remove a tiny piece of tissue from the area in question.

The biopsy process itself usually takes only minutes and causes little discomfort due sedation given beforehand making entire experience more comfortable overall indeed.
