Bowel cancer is a general term for cancer that begins in the large intestine, the lower part of the gut where water is excreted from the digestive tract before being excreted from the body as solid waste.
The symptoms of bowel cancer may go unnoticed and may not necessarily make you sick. However, in some cases, bowel cancer can prevent the passage of digestive waste through the intestine, and this is known as bowel obstruction.
Cancer Research UK explains that it is a serious complication that requires urgent medical attention.
The symptoms associated with intestinal obstruction are usually more severe than the main symptoms. One of the clear signs is pain (usually cramps in abdominal pain), says the Cancer Research Center.
Colic is characterized by pain that comes and goes, intensifies and then gradually subsides.
In adults, this pain may occur only once or recur weeks, months or even years after the first episode.
According to Cancer Research UK, other signs of bowel obstruction include:
Feeling of bloating and fullness.
I feel sick.
Vomiting in large quantities (including indigestible food or intestinal fluid).
Constipation (occurs without gas and without intestinal sounds).
What are the main symptoms of bowel cancer?
The NHS has found that more than 90% of people with bowel cancer have one of the following groups of symptoms:
Steady change in bowel habits – more frequent defecation, with looser, looser stools and sometimes with abdominal pain.
Blood in the stool without other symptoms of hemorrhoids.
Abdominal pain, discomfort or bloating is always caused by food – something that sometimes leads to a reduction in the amount of food you eat and weight loss.
Several studies have shown that eating a lot of red and processed meat increases the risk of bowel cancer.
