Bowel cancer, also known as colorectal cancer, can affect any part of the colon or rectum; it may also be referred to as colon cancer or rectal cancer, depending on where the cancer is located.
Bowel cancer screening is for people who do not already have bowel cancer, symptoms of bowel cancer, or any reason to have a high risk of bowel cancer.
Patient-centred care is healthcare that is respectful of, and responsive to, the preferences, needs and values of patients and consumers.
Bowel Cancer Australia provides essential support services uniquely designed for bowel cancer patients via our confidential Helpline with specialist telehealth support, as well as a national Peer-to-Peer Support Network and Buddy Program.
Bowel Cancer Australia funds research that has the potential to improve survival and/or help build a path toward a cure and integrates published research into our awareness, advocacy, and support strategies.
Bowel Cancer Australia relies upon donations and the support of hard working and enthusiastic fundraisers across the country to continue our life saving work. We raise funds to continue our life-saving work and inspire others to do the same, so everyone affected by bowel cancer can live their best life.
The 5-year relative survival rate for bowel cancer increased from 55.5% to 71.3% between 1991-1995 and 2016-2020.
Please note: the latest available 5-year survival data by stage at diagnosis and time is 2011.
When someone is diagnosed with bowel cancer, one of the first questions they may ask is, ‘What are the chances I will survive?’
Specialists answer this question using statistics.
Statistics are estimates that describe trends in large numbers of people.
They can help with predictions, but they can’t tell what will actually happen to you.
How long someone will live after a bowel cancer diagnosis (prognosis) is affected by a range of factors, such as the specific characteristics of the individual, including their age and general health at the time of diagnosis, the type and stage of cancer they have and the treatments received.
Researchers usually give survival statistics as rates for specific cancer types.
The percentage of people who will be alive at a certain time after diagnosis.
The ‘overall survival rate’ is when it includes all people with a specific cancer type.
Survival rates can describe any given length of time. However, researchers usually give cancer statistics as a 5-year relative survival rate.
The percentage of people who will be alive 5 years after diagnosis.
It does not include those who die from other diseases.
Example: The 5-year relative survival rate for people with bowel cancer is 71.3% (2016-2020). This means that around 70 out of every 100 people with bowel cancer will be alive five years after diagnosis.
Researchers also calculate survival statistics for specific cancer stages.
The stage helps describe where a cancer is located, if or where it has spread, and whether it is affecting other parts of the body.
Survival statistics can vary by stage.
Example: The 5-year relative survival rate for people diagnosed with stage 1 bowel cancer is 98.6% (2011). This means that nearly 99 out of every 100 people with stage 1 bowel cancer will be alive in 5 years after diagnosis.
Researchers base 5-year survival statistics on people whose cancer was treated at least five years ago.
The statistics may not reflect the latest treatment advances.
The 5-year relative survival rate includes people in remission.
Remission is the temporary or permanent absence of disease.
This survival rate also includes those still receiving treatment.
Disease-free survival (DFS) statistics and progression-free survival (PFS) statistics are more specific.
Specialists often use them to evaluate cancer treatments.
The percentage of people in complete remission after finishing treatment.
The percentage of people who did not have new tumor growth or cancer spread during or after treatment.
The disease may have responded to treatment completely or partially, or the disease may be stable.
This means the cancer is still there but not growing or spreading.
Prognosis depends on the stage of cancer at diagnosis.
For example, the 5-year relative survival rate for early-stage bowel cancer is as high as 98.6%. For metastatic bowel cancer, the rate is around 13.4%.
Specialists often use 5-year relative survival rates to evaluate and compare treatment options.
They consider the survival rate a good indication of the following:
Survival statistics help specialists decide which treatments provide the most benefit.
They also help specialists weigh the benefits against the risks.
For example, a specific treatment may be very effective in treating the cancer, but a person might experience unpleasant side effects from it.
Statistics can provide helpful information, but they are not the only factor used for treatment planning.
The word ‘cure’ does not apply perfectly to cancer.
Sometimes undetected cancer cells are still in the body after treatment. These cells can cause the cancer to come back later. Specialists call this a recurrence or relapse.
The medical community considers many cancers ‘cured’ when specialists cannot detect cancer five years after diagnosis. But recurrence after five years is still possible.
