Many cancer patients take dietary supplements in hopes of keeping their disease at bay, but British researchers say there's little evidence it will pay off.

In fact, they add, supplements may not only be ineffective, but harmful as well.

"We found 1 in 5 people who had been treated for cancer mistakenly thought that taking vitamins or other supplements would help reduce the ris...

New research offers fresh proof that the COVID-19 pandemic delayed cancer diagnoses in the United States, increasing patients' risk for poor outcomes.

For the study, researchers analyzed data from more than 9 million patients at over 1,200 Veterans Affairs (VA) medical facilities.

Procedures to diagnose cancer were used less often and there were fewer new cancer diagnoses in 2020 t...

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...

People who were exposed to a particular hormonal medication in the womb may have a heightened risk of cancer later in life, a new study suggests.

Researchers found the increased cancer risk among adults whose mothers had been given injections of a synthetic progesterone known as 17-OHPC, or 17P, during pregnancy. The study participants were born in the 1960s, when the drug was used to hel...

Black, Hispanic and Asian men in the United States are less likely than white men to receive a follow-up MRI after a screening suggests prostate cancer, a new study finds.

"We can't say definitively if the reason Black, Hispanic, and Asian men did not receive this particular test is that physicians did not refer them for it, or if the patients opted themselves out of further testing," sai...

A urine test might one day be able to tell which prostate cancer patients need immediate treatment and which don't, British researchers report.

"Prostate cancer can be divided into low and high risk -- the low-risk men rarely require treatment, and the high-risk certainly do," said study author Jeremy Clark, a senior research associate at Norwich Medical School at the University of E...

After prostate cancer surgery, men can safely undergo fewer radiation treatments at higher doses, a new clinical trial shows.

Researchers found that the shorter regimen -- given over five weeks, instead of seven -- did not raise patients' odds of lasting side effects.

Safety has been a "major concern" because when patients have fewer radiation treatments, the daily dose needs to be ...

American cancer patients spent more than $21 billion on their care in 2019, a new report shows.

That $21.09 billion included out-of-pocket costs of $16.22 billion and patient time costs of $4.87 billion. Patient time costs are the value of the time patients spend traveling for, waiting for and receiving care.

"As the costs of cancer treatment continue to rise, greater attention to a...

Private insurers paid out about $156.2 billion in 2018 for U.S. patients with the 15 most common cancers.

Medication was the largest expense and drugs for breast, lung, lymphoma and colon cancers accounted for the largest chunk of those costs, according to a Penn State College of Medicine study.

"The public often hears that the U.S. spends an inordinate amount of money on health car...

A pair of experimental tests could help doctors detect colon or prostate cancer with just a sample of blood or saliva.

One test examines a person's blood for four biomarkers linked to inflammation. In a small study, it outperformed the fecal blood test now used in colon cancer screening, said lead researcher Dr. Mona Eldeeb, of Alexandria University Medical Research Institute in Egypt.

Twenty years on, responders to the World Trade Center attacks in New York City are showing increased risks of certain cancers, two new studies confirm.

Researchers found higher-than-average rates of prostate cancer among firefighters, medics and other workers who toiled at the disaster site on and after Sept. 11, 2001.

And compared with firefighters from other major U.S. cities...

Does having an enlarged prostate doom you to prostate cancer?

Far from it, a new study suggests.

Also called benign prostatic hyperplasia (BPH), the condition may actually provide some protection for men from developing prostate cancer, researchers report.

"Men are often anxious about prostate cancer, as it is the second most common cancer in men, with some worrying BPH increa...

Widowers have a higher risk for advanced prostate cancer than men who are part of a couple, Canadian researchers say.

The new findings are from an analysis of 12 studies comparing 14,000 men newly diagnosed with prostate cancer and 12,000 healthy men.

The study -- recently published in the European Journal of Epidemiology -- suggests that social environment is an important ...

Significant fatigue at the start of cancer treatment is associated with a greater risk of severe side effects and shorter survival, a new study finds.

Researchers analyzed data from four clinical trials of lung cancer or prostate cancer treatments that were conducted by the SWOG Cancer Research Network, a cancer clinical trials group funded by the U.S. National Cancer Institute.

The...

Don't believe everything you read on social media about cancer and cancer treatment.

A new study finds that one-third of the most popular articles on social media about treatment for common cancers contains misinformation -- and most of it can be downright dangerous.

"The worst-case scenario is when it leads to a person declining proven cancer treatments in favor of a treatment tha...

Black men in the United States have higher rates of prostate cancer than white men, yet they were far less likely to have surgery for their cancer during the first wave of the COVID-19 pandemic, a new study finds.

Researchers analyzed data from a Pennsylvania urologic database to compare prostate removal (prostatectomy) rates among Black and white patients who had untreated prostate cance...

When men have advanced prostate cancer, obesity might offer something of a survival advantage, a preliminary study suggests.

Researchers in Italy found that among men with prostate cancer that had spread throughout the body, those who were obese were less likely to die over the next few years.

Roughly 30% were still alive after three years, versus 20% of normal-weight and overweight...

One of the big issues in prostate cancer care is overdiagnosis -- men who are treated for low-risk, slow-growing tumors that might be better left monitored and untreated.

Now, research out of Sweden suggests that having patients undergo MRI screening, along with targeted biopsies, could reduce the number of prostate cancer overdiagnoses by half.

The new approach can detect just as...

Black American military veterans with aggressive prostate cancer who would benefit from surgery or radiation are less likely to get those treatments than men of other races, despite equal access to health care, a new study finds.

"Despite great strides in prostate cancer care over the past few decades, racial disparities in care persist, and there remains a lot to be done to better unders...

Could a new one-and-done blood test designed to detect as many as 50 different types of cancer become a diagnostic game changer?

Yes, say researchers, who report the method appears accurate and reliable at identifying and locating cancer, including some kinds for which there are now no effective screening methods.

"[The test] sets the stage for a new paradigm of screening individual...

Patients with advanced prostate cancers may have newfound hope: Researchers identified a new potential treatment for men with metastatic castration-resistant prostate cancer, which has no cure.

Metastatic castration-resistant prostate cancer means the disease continues to spread despite therapies that deplete male hormones (androgens) such as testosterone, which are thought to "feed" tum...
