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 risk of bowel cancer increases with age
As people age, they are more likely to grow polyps, some of which may undergo gene changes that turn normal tissue into cancer.
This is why age is considered a non-modifiable bowel cancer risk factor.
Bowel cancer is more frequently diagnosed in people aged 70-74, with the median age of diagnosis 70.5 years.
The trend in age-specific incidence rates for bowel cancer in 2020 (the most recent year for which actual data is available) was similar to that of previous years, with the incidence rates rising sharply for those aged 50 years and over.
Although the risk of developing bowel cancer increases with age, anyone at any age, can develop bowel cancer.
Rates of bowel cancer in people under age 50, known as early-onset bowel cancer, are on the rise.
The risk of being diagnosed with bowel cancer before age 40 has more than doubled since the year 2000.
Lifetime risk of developing or dying from bowel cancer
The lifetime risk of developing or dying from bowel cancer refers to the chance a person has, over the course of their lifetime, of being diagnosed with or dying from bowel cancer.
The lifetime risks of developing and dying from bowel cancer for men and women is based on actual incidence data from 2020 and mortality data from 2021, the most recent years for which data are available.
The risk is expressed both in terms of a percentage and as odds.
The risk that a woman will develop bowel cancer during her lifetime is 6.2%.
This means she has about 1 chance in 16 of developing bowel cancer. Put another way, 1 out of every 16 women in Australia will develop bowel cancer during her lifetime.
The risk that a woman will die from bowel cancer during her lifetime is 2.8%.
This means she has about 1 chance in 36 of dying from bowel cancer. Put another way, 1 out of every 35 women in Australia will die from bowel cancer during her lifetime.
These numbers are average risks for the overall Australian population.
Your risk may be higher or lower, depending on your particular risk factors.
The risk that a man will develop bowel cancer during his lifetime is 6.7%.
This means he has about 1 chance in 15 of developing bowel cancer. Put another way, 1 out of every 15 men in Australia will develop bowel cancer during his lifetime.
The risk that a man will die from bowel cancer during his lifetime is 2.9%.
This means he has about 1 chance in 35 of dying from bowel cancer. Put another way, 1 out of every 35 men in Australia will die from bowel cancer during his lifetime.
