Bowel cancer, also known as colorectal cancer, is the third most common form of cancer in the world. Unfortunately, it is often not detected until it has already spread, making it more difficult to treat. It is estimated that nearly 25% of cases are diagnosed at an advanced stage. This means that the patient has had the cancer for a long time without knowing it.
Symptoms of Bowel Cancer
There are several common symptoms that can be associated with bowel cancer. These include changes in bowel habits, such as persistent constipation or diarrhoea, blood in the stools, abdominal pain, and unexplained weight loss. However, it is important to note that these symptoms can also be caused by other conditions, such as irritable bowel syndrome.
Diagnosis of Bowel Cancer
If any of the above symptoms are present, it is important to see a doctor as soon as possible. They will be able to carry out tests to determine if the symptoms are caused by bowel cancer or another condition. These tests may include a colonoscopy, where a scope is inserted into the rectum to check for any abnormalities, or a stool sample to check for blood.
How Long Can You Have Bowel Cancer Without Knowing?
Unfortunately, it is impossible to answer this question definitively. The length of time a person can have bowel cancer without knowing will depend on individual circumstances. Some people may show symptoms early, while others may not show any symptoms until the cancer has spread. It is therefore important to be aware of the potential symptoms and to see a doctor if anything is out of the ordinary. Early detection is key to increasing the chances of successful treatment.
