DNA methylation patterns in blood and tumor samples can be used to estimate a person's past exposure to environmental factors like smoking, education level, and diet in studies of colorectal cancer.
Higher use of the herbicide picloram in a geographic area is linked to higher rates of early-onset colorectal cancer, based on molecular changes in tumor tissue and population data adjusted for other...
People who develop colorectal cancer at a younger age show different patterns of DNA methylation compared to those who develop it later in life, and these differences are linked to long-term...
In the United States, the number of people under age 50 diagnosed with colorectal cancer has risen significantly since the 1990s, from about 8.6 to 12.9 cases per 100,000 people.
People who are more physically active tend to have a lower risk of developing colorectal cancer, while those who spend more time sitting have a higher risk.
People with obesity have a higher chance of developing colorectal cancer compared to those without obesity, with men showing a greater increase in risk than women.
People who consume more dietary fiber relative to their total energy intake have a lower likelihood of developing colorectal cancer.
DNA damage from certain bacteria in early childhood may lead to colorectal cancer that appears later in adulthood.
Over the last 20 years, the number of new cases of colorectal cancer in people under 50 has roughly doubled compared to earlier rates.
A bacterial toxin called colibactin can cause DNA damage in children, and this damage can be found as one of the earliest genetic changes in tumors that develop in the colon later in life.
People who eat 10 servings of ultra-processed foods per day have a 45% higher rate of developing colorectal adenomas than those who eat three servings per day.
People exposed to the herbicide picloram may show distinct patterns of DNA methylation in colorectal tumors that develop at an early age.
Certain strains of Escherichia coli that produce colibactin cause distinct double-strand breaks in the DNA of cells lining the colon, leading to characteristic mutation patterns known as SBS88 and...
Abdominal pain by itself is a very unreliable sign of colorectal cancer in people visiting a primary care doctor; only about 3 in 100 patients with this symptom actually have the cancer, so doctors...
People who have both abdominal pain and rectal bleeding do not have a higher chance of colorectal cancer than those with rectal bleeding alone, and the combination may be more often linked to...
People who experience rectal bleeding along with a change in their bowel habits are 1.8 times more likely to have colorectal cancer compared to those without these symptoms, which helps doctors...
People who have rectal bleeding and also lose weight without a known reason are almost twice as likely to have colorectal cancer compared to those who have rectal bleeding alone.
Among adults aged 50 and older, having iron-deficiency anaemia is associated with a 9.7% chance of having colorectal cancer, which is higher than the risk linked to most other symptoms, so it should...
Among adults aged 50 and older who experience rectal bleeding during a primary care visit, about 8 out of 100 are found to have colorectal cancer, meaning most do not have cancer but the symptom...
Men who eat more ultra-processed foods have a higher likelihood of developing cancer in the lower part of the colon, even when accounting for their intake of other foods like meat, fruits, and...
Studies show that eating ultra-processed foods does not appear to increase colorectal cancer risk in women, but it is linked to higher risk in men. This difference may be due to biological or dietary...
Among women, eating more ready-to-eat mixed dishes like frozen meals is linked to a higher chance of developing colorectal cancer, while eating more yogurt and dairy-based desserts is linked to a...
People who eat more ready-to-eat meat, poultry, or seafood products have a higher chance of developing colorectal cancer, and those who drink more sugar-sweetened beverages also have a higher chance,...
Men who eat a lot of ultra-processed foods have a higher risk of developing colorectal cancer, especially in the distal colon, compared to those who eat less, even when accounting for body weight and...
