Radiation therapy might not be necessary in treating some forms of rectal cancer and lymphoma, sparing patients from the toxic treatment, a pair of new clinical trials shows.
One trial found that rectal cancer patients whose tumors shrink in response to chemotherapy can safely skip the radiation therapy that's normally provided prior to surgery, researchers reported at the American Societ...
Yet another study is chipping away at the idea that colon and rectal cancers are diseases of older age: In the past couple decades, Americans younger than 40 have shown the steepest rise in advanced cases of these cancers.
The research adds to evidence of a disturbing, and not yet completely understood, increase in early-onset
Most American adults don't know that alcohol boosts cancer risk, but a majority support steps to increase awareness of the link, a new nationwide survey shows.
""It is important that people are made fully aware of the potential harms of alcohol so that they may make informed decisions about alcohol consumption," said study author Kara Wiseman. She's an assistant professor of public health...
U.S. cancer clinical trial participants have become more diverse in makeup, but certain groups remain underrepresented, a new study finds.
It's important to have a wide range of participants in clinical trials, to find out if treatments are safe and effective for people with different characteristics, according to the National Cancer Institute (NCI), which has a number of initiatives to b...
Black American women with low levels of vitamin D have higher odds of developing colon cancer, according to a new research that echoes previous findings in white women.
Researchers used a vitamin D prediction model for nearly 50,000 participants in the Black Women's Health Study and concluded that those with predicted levels in the bottom 25% had an estimated 40% higher risk of colon canc...
There's good news for health-conscious sausage and bacon lovers.
A new study suggests the Japanese knotweed plant could be used to make healthier cured meats.
According to researchers, this fast-growing plant that invades gardens and buildings contains a chemical that could take the place of the preservative nitrite, which has been linked to cancer, in cured meats. That might not on...
Here's another reason to avoid unnecessary use of antibiotics: Long-term use of these medications could increase your risk of colon cancer, researchers say.
"While in many cases antibiotic therapy is necessary and saves lives, in the event of less serious ailments that can be expected to heal anyway, caution should be exercised. Above all to prevent bacteria from developing resistance but...
Immunotherapy helped extend the lives of some patients with the most common type of advanced colon cancer, researchers report.
The new findings are important, they noted, because immunotherapy doesn't typically work against microsatellite stable (MSS) colon cancer. These patients have few treatment options once their disease no longer responds to chemotherapy.
Antibiotics may increase the risk of colon cancer, especially in younger people, U.K. researchers report.
"To our knowledge, this is the first study to link antibiotic use with the growing risk of early-onset colon cancer -- a disease which has been increasing at a rate of at least 3% per year over the last two decades," said study co-author Sarah Perrott, a cancer researcher at the Unive...
In a finding that offers the first evidence that the human papillomavirus (HPV) vaccine is indeed protecting women from cervical cancer, new research shows cases in the United States have slowly but steadily declined over the last decade and a half.
However, other HPV-related cancers like anal, rectal and oral tumors continue to increase, suggesting that regular cancer screening also play...
New research offers insight into why regular, long-term use of low-dose aspirin may reduce the risk of death from colon and rectal cancers.
Resarchers found that aspirin prevents blood cells called platelets from producing an enzyme that allows them to clump together. Tumor cells can attach to these clumps and spread (metastasize) throughout the body.
Breast cancer has surpassed lung cancer as the world's most commonly diagnosed cancer.
In 2020, there were an estimated 19.3 million new cancer cases and nearly 10 million cancer deaths worldwide, according to the Global Cancer Statistics 2020 report from the American Cancer Society (ACS) and the International Agency for Research on Cancer.
Social and financial struggles are common among Black American cancer survivors and take a heavy toll on their health-related quality of life, according to a new study.
Health-related quality of life among cancer survivors -- how a person perceives their mental, physical and social well-being -- tends to be significantly lower among Black Americans than in other groups.
Girls who are vaccinated against human papillomavirus (HPV) may drastically cut their chances of developing cervical cancer by age 30, a huge, new study finds.
Researchers found that of more than 1.6 million young Swedish women, those who'd gotten the HPV vaccine were about two-thirds less likely to be diagnosed with cervical cancer than their unvaccinated peers.
Many Americans at high risk for colon cancer don't know how often they need to have a screening colonoscopy, researchers say.
The report follows the recent death of actor Chadwick Boseman, who died Aug. 28 at age 43 after a private, four-year battle with colon cancer. Boseman was best known for playing the superhero Black Panther.
Cities around the world are increasingly turning to streetlights emitting so-called "blue light," and it's also common in smartphones, laptops and tablets. Now, a study hints that excess exposure to blue-spectrum light might raise a person's odds for colon cancer.
As a team of Spanish researchers noted, prior studies have suggested that blue light emitted by most white LEDs (light-emi...
Scientists are working on a blood test that may catch five common cancers years sooner than current methods.
The blood test, which is still experimental, hunts for certain genetic "signatures" associated with tumors. Researchers found that it can detect five types of cancer -- colon, esophageal, liver, lung and stomach -- up to four years earlier, compared to routine medical care.
Many cancer patients have faced delays to their health care during the coronavirus pandemic, but with what consequences?
Researchers at Beth Israel Deaconess Medical Center in Boston analyzed 15 years of data to determine how long surgery for certain types of cancer can be delayed without harming patients' chances of survival. The study began in early spring, as the pandemic led many ...
Low-dose aspirin may reduce the risk of several types of digestive tract cancers, according to a team of researchers in Europe.
For the new study, the researchers analyzed 113 studies investigating colon/rectal ("bowel"), head and neck, esophageal, stomach, liver, gallbladder, bile duct and pancreatic cancers in the general population. The studies were published up to 2019.
With screening, colon cancers can effectively be detected and prevented. Though colon cancer is the third-leading cause of cancer death in the United States, one-third of Americans over age 50 are not getting screened.
"Screening saves lives and can prevent colon cancer," said Dr. Susanne Shokoohi, a gastroenterologist at Loyola Medicine in Maywood, Ill.
Obesity increases the risk for colon cancer, but weight-loss surgery may bring the risk back to normal, French researchers report.
People who are obese have a 34% higher risk of colon cancer than the general population, but any type of bariatric (weight-loss) surgery can bring their risk back in line, according to the authors of a new study.
Young men who have sex with other men don't fully grasp their risk for human papillomavirus (HPV) infection, due to a lack of information from health care providers, researchers say.
Interviews with men in their early 20s who are gay, bisexual or who identify as straight but have sex with men found that they knew little about HPV, including how it is transmitted, its symptoms and how ...
Gastrointestinal bleeding in patients taking blood thinners for an irregular heartbeat should prompt doctors to check for colon cancer, a new study advises.
Researchers looked at more than 125,000 patients in Denmark with the heart rhythm disorder atrial fibrillation (a-fib). They reported that those with gastrointestinal bleeding were 11 to 24 times more likely than others to be diag...
The rate of colon cancer among Americans spikes sharply between the ages of 49 and 50, a new study finds -- supporting the case for earlier screening for the disease.
Researchers say the uptick between those two ages does not reflect an actual increase in the occurrence of colon cancer but the fact that screening for the disease has traditionally begun at age 50. So "latent" cancers ...
Taking certain antibiotics -- especially multiple times or for long courses -- may put you at risk for colon cancer, a large new study suggests.
The researchers found that as people's antibiotic use increased, their odds of being diagnosed with colon cancer inched up. Specifically, the risk was tied to antibiotics that kill anaerobic bacteria -- which include common drugs like penicil...
Skipping that grilled T-bone and having chicken instead could reduce a woman's risk of breast cancer, a new study suggests.
The World Health Organization has declared red meat a probable carcinogen, and this new study adds breast cancer to a list of cancers linked to red meat, including beef, veal, pork, lamb and some game.
Breast cancer is the number one cancer among women...
More than 8.7 million years of life and about $94 billion in earnings were lost to cancer in the United States in 2015, researchers say.
Cancer is the nation's second-leading killer and is expected to cause nearly 607,000 deaths this year. These premature deaths and the lost productivity they cause impose a significant economic burden, the study authors explained.
Millions of tons of nitrate from industrial farming find their way into America's drinking water each year, causing thousands of cases of cancer and other health problems, an environmental advocacy group says.
In a new report, researchers from the Environmental Working Group (EWG) quantify the risk. They say nitrate is responsible for nearly 12,600 cases of cancer a year.
Colon cancer rates among those under 50 in the United States are rising, and they're rising the most rapidly in western states, a new study finds.
"It was surprising that the largest increases were in the West, where you have more healthy behaviors," said lead researcher Rebecca Siegel, scientific director of surveillance research at the American Cancer Society.
