Newer cancer drugs that enlist the body’s immune system are improving the odds of survival, but competition between them is not reining in prices that can now top $250,000 a year.
The drugs’ success for patients is the result of big bets in cancer therapy made by Bristol-Myers Squibb Co, Merck & Co Inc and Roche Holding AG, among others in big pharma. The industry’s pipeline of cancer drugs expanded by 63% between 2005 and 2015, according to the QuintilesIMS Institute, and a good number are reaching the market.
The global market …

Long-term use of antibiotics increases the risk later in life of developing colon polyps, often a precursor of bowel cancer, researchers said Wednesday.
The findings, published in the journal Gut, boost evidence that the digestive tract’s complex network of bacteria may play a key role in cancer emergence.
Earlier research has linked antibiotic use to developing bowel cancer but the potential association with these abnormal growths had not been explored.
To find out more, Andrew Chan of the Massachusetts General Hospital in Boston combed through health records for 16,642 women who were 60 …

What causes cancer? A new study suggests that cells make random mistakes while dividing, accounting for most of the mutations in tumors, rather than family history or environmental factors.
The report in the journal Science was authored by the same team that led a controversial study in January 2015 that said random DNA mutations, or in other words just “bad luck,” is often to blame for cancer.
This time, they expanded their mathematical model based on DNA sequencing and epidemiologic data to 69 countries worldwide.
“Two-thirds of the mutations that occur in cancers …

Scientists have developed a new method to neutralise a dangerous fungal toxin affecting crops that can lead to cancer, childhood stunting and other health threats.
Researchers from the University of Arizona (UA) said they had created a genetically modified maize plant that is edible even when infected with a mold that produces aflatoxin, a carcinogenic substance.
About 16 million tons of maize, equivalent to almost the total output of South Africa, is thrown out each year worldwide due to contamination, as even small amounts can make an entire harvest unsafe for consumption.
In …

Scientists have unveiled a test for detecting pancreatic cancer, one of the deadliest forms, in less than a drop of blood.
The diagnostic method is fast, cheap and ultra-sensitive, and can be adapted to test for other diseases whose fingerprints are detectible in blood, they wrote in the journal Nature Biomedical Engineering.
A team in the United States and China identified a protein dubbed EphA2 found in pancreatic tumours.
They then developed a test to detect its presence in as little as 0.001 millilitres of blood plasma—the liquid component of blood, in which …

Late diagnosis of cancer leads to millions of people enduring needless suffering and premature death, and efforts to catch the disease earlier must be stepped up, the World Health Organization says.
In a report launched for World Cancer Day on Saturday, the WHO said it wanted to improve chances of survival for cancer patients by ensuring health services focus on diagnosing and treating the disease earlier.
“Diagnosing cancer in late stages, and the inability to provide treatment, condemns many people to unnecessary suffering and early death,” said Etienne Krug, a WHO expert …

Image-scanning software developed at Stanford University can distinguish deadly skin cancers from benign ones as accurately as top dermatologists, according to a new study.
The potentially life-saving technology could soon be incorporated in a smart phone, the researchers said, an advance reminiscent of the diagnostic device wielded by Dr McCoy in the 1960s “Star Trek” sci-fi series.
Adapting a Google algorithm designed to distinguish between categories of objects based on images—telling a cat from a dog, for example—the Stanford team compiled a database of nearly 130,000 photos of skin disease.
To be effective, …

A drug that is given to late-stage cancer patients to help ease the constipation brought on by morphine has been shown to extend their lives, researchers said.
Methylnaltrexone, approved by the US Food and Drug Administration in 2008 to treat opioid-induced constipation, could play a role in cancer therapy, said researchers who presented their findings at the meeting of the American Society of Anesthesiologists in San Diego.
“Early on, we began to suspect that methylnaltrexone might inhibit cancer growth,” said Jonathan Moss, lead author of the study and professor of anesthesia and …

Sausages, ham and other processed meats cause bowel cancer, and red meat “probably” does too, a UN agency warned Monday, in a potentially heavy blow for the fast-growing livestock industry.
A review of 800 studies from around the world found “sufficient evidence in humans that the consumption of processed meat causes colorectal cancer,” said the International Agency for Research on Cancer (IARC).
The finding, it added, supports “recommendations to limit intake of meat” — particularly in processed forms.
The category includes meat that has been salted, cured, fermented or smoked — hot dogs, …

Researchers at the University of Louisville School of Medicine are now using breath analysis to detect the presence of lung cancer.
Preliminary data indicate that this promising noninvasive tool offers the sensitivity of PET scanning, and has almost twice the specificity of PET for distinguishing patients with benign lung disease from those with early stage cancer.
Michael Bousamra II, MD, Associate Professor, Department of Cardiovascular and Thoracic Surgery, presented the results of the study at the AATS 2014 Conference on April 29, 2014.
A reliable, noninvasive diagnostic method imposes less physical and financial …
