Signs and symptoms of bowel cancer The 3 main symptoms of bowel cancer are blood in the stools (faeces), a change in bowel habit, such as more frequent, looser stools, and abdominal (tummy) pain. However, these symptoms are very common.
Change in shape
Thin stools are a sign of colon cancer. Any time you notice a narrow or ribbon-like stool, it indicates changes in your colon.
Stool from Colon Cancer does not always have a "typical" appearance, and stool color will depend on how advanced your Cancer has become and what nutrients you may be lacking in your Colon, resulting in constipation, diarrhea, or neither.
Blood in the stool, as well, tends to be more common amongst patients with colon cancer rather than IBS. This might be difficult to spot with the naked eye. However, if the stool is darker than usual, this might be the result of blood leaking from polyps in the colon.
Diarrhea: Caused by an overflow of intestinal fluid around a partial obstruction. Alternating constipation and diarrhea: A more telling sign of colon cancer. Blood in stool: Also known as hematochezia, which can be bright red if the tumor is near the rectum or dark red or maroon if higher up in the colon.
Red flags to consider include the following: abdominal cramps and pain. diarrhoea. constipation.
Many cases of colon cancer have no symptoms. If there are symptoms, the following may indicate colon cancer: Abdominal pain and tenderness in the lower abdomen.
Possible symptoms of bowel cancer
a lump that your doctor can feel in your back passage or tummy (abdomen), more commonly on the right side. a feeling of needing to strain in your back passage (as if you need to poo), even after opening your bowels. losing weight. pain in your abdomen or back passage.
You may feel a colicky type pain, or vague discomfort in your abdomen. You may also feel generally unwell, for example listless or tired, because you have been losing blood from the bowel and may have become anaemic (lack of red blood cells).
Currently, three types of stool tests are approved by the US Food and Drug Administration (FDA) to screen for colorectal cancer: guaiac FOBT (gFOBT); the fecal immunochemical (or immunohistochemical) test (FIT, also known as iFOBT); and multitargeted stool DNA testing (also known as FIT-DNA).
"Overall, any change in bowel habit, such as diarrhea, can be a sign of colon cancer. Diarrhea can be either a secretory process (the tumor leaks fluid) or from partial obstruction and overflow around the tumor. Sudden constipation or difficulty passing stool along with bleeding are seen more commonly.
Stools that are narrower than usual
Narrow stools, like pencil-thin stools, can be caused by an obstruction in the colon, like a tumor. For the most part, narrow stools that occur infrequently are not a cause for concern. But if you experience narrow stools for more than a week, seek medical attention from your doctor.
Colorectal Cancer
Some research has found that changes in stool smell may be a sign of these types of cancer. However, this condition is rare, even among those with IBD, and bad-smelling stool is much more likely to be caused by other factors.
The main test for bowel cancer is a colonoscopy. This is where a thin, flexible, tube with a camera is used to look inside your bowel. It may be uncomfortable but it should not be painful. You'll be offered a sedative and painkillers to help make you feel more comfortable.
The 3 main symptoms of bowel cancer are blood in the stools (faeces), a change in bowel habit, such as more frequent, looser stools, and abdominal (tummy) pain.
Colon cancer is typically slow-growing, starting as a benign polyp that eventually becomes malignant. This process may occur over many years without producing any symptoms. Once colon cancer has developed, it may still be years before it is detected.
Blood in the stool that is either bright red, black or tarry. Unintentional weight loss. Stools that are narrower than usual. Diarrhea, constipation, or feeling that the bowel does not empty completely.
Abnormal poop
excessive straining when pooping. poop that is red, black, green, yellow, or white. greasy, fatty stools.
Changes in bowel habits can be caused by a temporary infection, taking certain medications, or by a long-term (chronic) condition. Some chronic conditions that commonly cause changes in bowel habits include: Celiac disease. Constipation.
See your health care provider if more-frequent bowel movements also are accompanied by any of the following signs or symptoms: Changes in the consistency, volume or appearance of your bowel movements, such as repeatedly passing narrow, ribbonlike stools or loose, watery stools. Abdominal pain.
Patients with early-onset CRC typically have more-advanced disease at diagnosis than patients with later onset colorectal cancer. Symptoms most commonly associated with early-onset CRC include hematochezia (fresh blood per rectum), abdominal or pelvic pain and bloating, and a change in bowel habits.
