Experts have raised the alarm
Cancer rates among young people are on the rise, but experts are yet to find a conclusive reason for the increase.
A major new study has revealed that there are eleven types of cancer that are becoming more common among young people.
Scientists from the Institute of Cancer Research and Imperial College London emphasised that cancer among young people is still rare, but that it is on the rise.
Although risk can be minimised by living a healthy lifestyle, experts warned that they do not have a conclusive answer for why rates of the disease are increasing among people under 50.
The study claims that the trend of people being more overweight has played a role in the increased rates of cancer, but this does not explain the full story.
For example, in cases of bowel cancer, scientists explained that for every 100 extra cases, 20 may be due to excess weight, leaving 80 with no clear explanation.
"It is very worrisome to hear the news that cancers are increasing in young people," Prof Montserrat García Closas told the BBC.
"However, there are things that can be done to reduce the risk of cancer by having a healthy lifestyle - for instance, being physically active and maintaining a healthy weight."
What are the symptoms of cancer in young people?
The Children and Young People's Cancer Association says many of the symptoms in young people can also be symptoms of common illnesses, so they may be easy to miss.
However, there are some things to look out for, including:
- Aches and pains that don't go away, which might feel worse at night or after exercise
- Unexplained lumps, bruises and swellings (which may or may not be painful)
- Reduced movement, numbing, tingling or weakness
- A new, strange-looking mole, a dark area of skin that was not there before, or a change in a mole or freckle you already have
- Finding it difficult to pee, or to control when you need to pee (wetting yourself), or peeing more often than usual
- Blood in your pee or poo
- Headaches
- Tiredness
- Unexplained weight loss or loss of appetite
- Sickness and vomiting
- Confusion, or changes in behaviour, thinking or personality
- Slow growth or development
What cancers are most common in young people?
The new analysis has provided a list of eleven cancers in particular that are seeing a rise in young people.
These eleven cancers are as follows: bowel cancer; thyroid, multiple myeloma, liver, kidney, gallbladder, pancreatic, womb lining (or endometrial), mouth, breast and ovarian cancers.
The most common cancers in young adults are bowel and breast cancers, with a combined 11,500 cases a year.
Cases of pancreatic and gall bladder cancer are much rarer.
Out of these cancers, the only ones seeing an increase in just young people are bowel and ovarian cancer. The other cancers are also increasing across other age groups.
