Occasionally, cancer can begin in one part of the body, but then start spreading to other areas – this is known as metastasis.
A new study, published in The Lancet journal, has found the biggest lifestyle risk factors for cancer.
According to the study, 44.4% of all cancer deaths could be attributable to preventable risk factors in 2019. In the research, smoking, drinking alcohol and obesity were found to be the biggest risk factors in that year.

Smoking took the lead as the biggest risk factor, accounting for 33.9%, based on research into 10million people who had died from cancer.
Co-senior author of the study, Christopher Murray said: "The burden of cancer remains an important public health challenge that is growing in magnitude around the world.”
This includes those who only smoke a few cigarettes a day or smoke occasionally.
Chemicals from cigarettes damage DNA and also make it harder for cells to repair any DNA damage.
Smoking also damages the parts of DNA that protect us from cancer.
Obesity
According to Cancer Research UK, "robust scientific evidence shows that being overweight or obese increases the risk of 13 different types of cancer".
Obesity increases the risk of the following cancers:
- Breast and bowel (two of the most common cancer types)
- Pancreatic, oesophageal and gallbladder (three of the hardest to treat cancers)
- Womb and ovarian
- Kidney, liver and upper stomach
- Myeloma (a type of blood cancer)
- Meningioma (a type of brain tumour)
Alcohol
Alcohol can cause seven different types of cancer – including breast, mouth and bowel cancer.
“Alcohol gets broken down into a harmful chemical and can also affect our body’s chemical signals, making cancer more likely to develop,” says Cancer Research.
The health charity added: “Alcohol gets broken down into a harmful chemical and can also affect our body’s chemical signals, making cancer more likely to develop.”
If you experience any cancer symptoms, or something that isn't normal for you, you should see your GP.
