Around one-third of deaths from cancer are due to tobacco use, high body mass index, alcohol consumption, low fruit and vegetable intake, and lack of physical activity.
Leading risk factors for preventable cancers are smoking, getting too much ultraviolet (UV) radiation from the sun or tanning beds, being overweight or having obesity, and drinking too much alcohol.
Lifestyle behaviors and environmental factors account for around 70-90% of cancer cases, according to new research published in the journal Nature. Share on Pinterest Researchers say up to 90% of cancer cases are caused by lifestyle and environmental factors, such as smoking.
Cancer is the second-leading cause of death worldwide.
10 million people die from cancer every year.
More than 40% of cancer-related death could be preventable as they are linked to modifiable risk factors such as smoking, alcohol use, poor diet and physical inactivity.

What are cancers mostly known for?
They're primarily known for being emotional, nurturing, and highly intuitive, as well as sensitive and at times insecure. Their elemental sign is water (as it is for Pisces and Scorpio), which makes sense when you consider the emotional depths associated with this sign.
The main reasons are genetics and certain environmental or behavioral triggers. The tendency to develop some types of cancer is believed to be inherited — that is, the genes you were born with might carry a predisposition for cancer.
Diet, obesity, and metabolic syndrome are very much linked to various cancers and may account for as much as 30–35% of cancer deaths, indicating that a reasonably good fraction of cancer deaths can be prevented by modifying the diet.
While plenty of research has shown that stress can cause cancer to grow and spread in mice, studies haven't shown a clear link between stress and cancer outcomes in people. But it's difficult to study stress in people for several reasons, including challenges with defining and measuring stress.
Risk factors such as highly processed foods, sugary beverages, obesity, Type 2 diabetes, sedentary lifestyle, and alcohol consumption have all significantly increased since the 1950s.
Cervical cancer is one of the most preventable cancers thanks to the HPV vaccine. HPV, or the human papillomavirus, causes 99% of all cervical cancers. The HPV vaccine, which is given in 2 doses, targets 9 different types of the virus.
What are the top 3 leading causes of cancer globally?
Tobacco use, alcohol consumption, unhealthy diet, physical inactivity and air pollution are risk factors for cancer and other noncommunicable diseases.
The most common type of cancer on the list is breast cancer, with 290,560 new cases expected in the United States in 2022. The next most common cancers are prostate cancer and lung cancer. Because colon and rectal cancers are often referred to as "colorectal cancers," these two cancer types are combined for the list.
Cancer is caused by changes to DNA. Most cancer-causing DNA changes occur in sections of DNA called genes. These changes are also called genetic changes. A DNA change can cause genes involved in normal cell growth to become oncogenes.
Studies strongly suggest that exercise lowers the risk for seven forms of cancer: bladder, breast, colon, endometrial, esophageal, kidney, and stomach. There are also intriguing clues that exercise helps prevent lung, blood, head and neck, ovarian, pancreatic, and prostate cancers, too.
According to the most recent statistical data from NCI's Surveillance, Epidemiology, and End Results (SEER) Program, the median age of a cancer diagnosis is 66 years. This means that half of cancer cases occur in people below this age and half in people above this age.
Inherited cancers are those caused by a mutation in a gene that was present in the egg or sperm cell at the time of fertilization. These cancers make up a fraction of common cancers—like breast, colon, and prostate cancer—as well as less common cancers like pancreatic and ovarian cancer.
