Bowel cancer is one of the most common cancers in the UK yet when caught early, statistics show strong success rates of treatment and survival. As we mark Bowel Cancer Awareness Month, it’s important to highlight the serious consequences of delayed diagnosis and treatment. When symptoms are missed, dismissed, or not properly investigated, the impact on patients and their families can be devastating.
The importance of early diagnosis
Bowel cancer is highly treatable when caught early.
According to Bowel Cancer UK, more than 90% of people diagnosed at the earliest stage survive for at least five years, compared to just 10% for those diagnosed at the latest stage.
However, delays in diagnosis can allow the cancer to progress, making treatment more complex and reducing the chances of a successful outcome.

A delayed diagnosis can occur for several reasons. In some cases, GPs or healthcare professionals fail to recognise symptoms or do not investigate them thoroughly. Test results may be misinterpreted, leading to missed opportunities for early intervention. Patients may also face delays in being referred for crucial investigations, such as colonoscopies, due to long NHS waiting times for specialist appointments and treatment. These factors can all contribute to a late-stage diagnosis, making the disease more difficult to treat effectively.
Recognising the signs of bowel cancer
Bowel cancer can present with a variety of symptoms, which may initially be mistaken for less serious conditions. Persistent changes in bowel habits, such as prolonged diarrhoea or constipation, could be a sign that something is wrong. Blood in the stool, unexplained weight loss, ongoing abdominal pain or bloating, and persistent fatigue or weakness should also be taken seriously. When these symptoms are ignored or misdiagnosed, crucial time can be lost in starting the necessary treatment.
When a bowel cancer diagnosis is delayed, the cancer can continue to grow and spread, requiring more aggressive treatments such as surgery, chemotherapy, or radiotherapy. This not only reduces survival rates but also significantly affects a patient’s quality of life. A late diagnosis may mean more invasive treatment is required, increasing the risk of complications and prolonging recovery time. For some, the cancer may spread to other organs, making it even harder to treat successfully. In addition to the physical toll, the emotional and financial strain on patients and their families can be immense.
