Bowel cancer symptoms

Bowel cancer symptoms can include blood in stools and a change in bowel habit. However, it might be possible to analyse risk of developing the disease in the first place by looking at hip measurements. 

 However now scientists have revealed how people can be alert to their own bowel cancer risk by measuring their waistline and hips.

A study published in the British Journal of Cancer revealed adding around 8cm to the hips is linked to an increased risk of 15 per cent risk of bowel cancer. 

Bowel cancer, also known as colorectal cancer, is a cancer situated anywhere in the large bowel, which includes the colon and rectum.

It is the fourth most common cancer in the UK and the second most common cause of cancer death with over 41,000 new cases diagnosed each year.

The study also revealed carrying fat around your middle could be as good an indicator of cancer risk as body mass index (BMI).

It shows that adding about 11cm to the waistline increased the risk of obesity related cancers - which can include stomach cancer - by 13 per cent.

Carrying excess body fat can change the levels of sex hormones, such as oestrogen and testosterone, can cause levels of insulin to rise, and lead to inflammation, all of which are factors that have been associated with increased cancer risk.

This is the first study comparing adult body measurements in such a standardised way for obesity-related cancers.

Scientists at the International Agency for Research on Cancer (IARC-WHO) showed that three different measurements of body size, BMI, waist circumference, and waist to hip ratio all predicted similar obesity-related cancer risk in older adults.

The study combined data from around 43,000 participants who had been followed for an average of 12 years and more than 1,600 people were diagnosed with an obesity-related cancer.

“Our findings show that both BMI and where body fat is carried on the body can be good indicators of obesity-related cancer risk,” said Dr Heinz Freisling, lead study author and scientist at IARC-WHO.
Specifically, fat carried around the waist may be important for certain cancers, but requires further investigation.”

“To better reflect the underlying biology at play, we think it’s important to study more than just BMI when looking at cancer risk. 

And our research adds further understanding to how people’s body shape could increase their risk.”

Being overweight or obese is the single biggest preventable cause of cancer after smoking and is linked to 13 types of cancer including bowel, breast, and pancreatic.

Dr Julie Sharp, Cancer Research UK’s head of health information, said: “This study further highlights that however you measure it, being overweight or obese can increase the risk of developing certain cancers, including breast and bowel.

“It’s important that people are informed about ways to reduce their risk of cancer. And while there are no guarantees against the disease, keeping a healthy weight can help you stack the odds in your favour and has lots of other benefits too.

“Making small changes in eating, drinking and keeping physically active that you can stick with in the long term can help you get to a healthy weight – and stay there. 

There are five key symptoms which could be an indicator of bowel cancer.

The high risk symptoms include:

A change in bowel habit
There are a few ways in which your bowel habit can change.
While most people experience changes in their bowel habits, if the number of times people pass a stool changes or whether the consistency of stools has change it could be an indicator of the disease. This could include persistent constipation or diarrhoea.

 Bleeding from the bottom of blood in your poo
If a person is experiencing persistent blood in the stools, which occurs for no obvious reason, or is associated with a change in bowel habit, it could be a sign of bowel cancer.
However, people can sometimes mistake blood in the stool for piles.

A lump in your stomach
you feel a lump in your tummy, which doesn’t go away, it could be a symptom of bowel 

 

Abdominal pain
If a person experiences persistent lower abdominal pain, bloating or discomfort, it could be a sign of the disease.

Weight loss and tiredness
People with bowel cancer sometime have iron deficiency anaemia, which can cause fatigue.

If you have lost weight without dieting - whether this is caused by a lack of appetite or feeling sick, it could be a sign of the disease .
 
Beating Bowel Cancer, a charity which supports and campaigns for people affected by bowel cancer said being aware of the symptoms of bowel cancer is the most important part of protecting yourself from the disease.

 It said if people spot the symptoms it is usually ‘quite safe to watch and wait for up to three weeks’.

However, experts from the charity warn that if the symptoms have not settled down, people should visit their GP.
