Roy Edward Disney dies from stomach cancer

A Walt Disney spokesman said the 79-year-old executive, nephew of Walt Disney, had battled the disease for a year and died in Newport Beach, California. Stomach cancer is diagnosed in 21,000 Americans a year and kills 10,000.

Some basics about radiation and cancer

A primer on radiation risk: ionizing radiation from X-rays and CT scans is a recognised carcinogen, damage accumulates over the years, and no dose is definitively safe, though exposure does not mean cancer will follow. One chest X-ray delivers 30 to 50 MREM, background about 300 a year.

CT scans cause cancer - studies

Two Archives of Internal Medicine studies estimate the cancer cost of CT radiation. One puts the risk at one in 270 women scanned by heart CT at age 40; the other models roughly 29,000 future cancers from scans done in 2007, about 14,000 from abdomen and pelvis scans.

Vitamin D May Boost Lymphoma Survival

Of 374 patients newly diagnosed with diffuse large B-cell lymphoma at the Mayo Clinic, half were vitamin D deficient. Those patients were 1.5 times more likely to see the cancer progress and twice as likely to die of it as patients with optimal levels.

Long chain omega 3 fatty acids help fight bowel cancer

Participants in the highest quartile of long-chain omega-3 intake had a 39% lower risk of distal large bowel cancer, researchers reported at an AACR prevention conference. The inverse association appeared among the 1,509 white participants but not the 369 black participants.

Low fat diet slows prostate cancer growth

Aronson's UCLA team put 18 untreated prostate cancer patients on a low-fat, high-fiber, soy-supplemented diet or a 40%-fat Western diet for four weeks. Serum from the low-fat group slowed LNCaP cell growth, alongside more omega-3 and less omega-6 fatty acid.

Don't count on coffee to fight prostate cancer

A roundup of short items on prostate cancer risk: exercise, sunlight and vitamin D, and green tea have each been linked to lower risk, red and processed meat to higher risk, and the piece calls coffee's reported benefit controversial.

Drinking coffee may lower advanced prostate cancer risk

Harvard researchers following 50,000 men found those who drank the most coffee were 60 percent less likely to develop aggressive prostate cancer than men who drank none. Caffeine showed no association, and which components might protect remains unknown.

Soy protein helps fight cancer and inflammation

University of Illinois researchers report that lunasin, a soy peptide recovered from soy-processing waste, triggered leukemia cell death through caspase-3 and reduced inflammation markers NF-kappa-B, interleukin-1 and interleukin-6. Eating 50 grams of soy protein for five days raised blood levels.

Green Tea Extracts May Protect You From Oral Cancer

In an M. D. Anderson trial, almost 60 percent of people on the two highest doses of green tea extract showed a clinical response, against 36 percent on the lowest dose and 18 percent on placebo. The lead researcher calls the results early and not proof that green tea prevents oral cancer.

Misleading Research Links Vitamin Supplements to Cancer

Two supplement trade groups say a JAMA study linking folic acid and B12 supplements to cancer deaths among Norwegian heart patients is misleading. CRN's Andrew Shao notes that 94 percent of those who developed lung cancer were current or former smokers.

Folic acid supplements raise cancer risk

Pooling two Norwegian heart disease trials with 6,837 patients, researchers found those given folic acid for about 3.5 years had 21 percent higher cancer risk, mostly folate-associated types, and were more likely to die during 6.5 years of follow-up.

Obesity, dietary fats affect prostate cancer risk

In a study of 40 men aged 50 to 80, half with prostate cancer, BMI was higher among the patients but not significantly so, though it tracked with tumor aggressiveness. Their total, saturated and unsaturated fat intake was higher, and omega-3, vitamin C and lycopene intake lower.

Obesity Linked to 100,000 Cancer Cases a Year

The American Institute for Cancer Research put numbers to obesity's cancer toll, attributing to body fat 49% of endometrial cancers, 35% of esophageal, 28% of pancreatic, 24% of kidney, 21% of gallbladder, 17% of breast and 9% of colorectal cases.

Obesity related to more than 100,000 cancer cases a year

The American Institute for Cancer Research estimates poor diet, inactivity and excess body fat account for more than 100,000 US cancer cases a year, including over 33,000 breast cancers. Panel member Laurence Kolonel cites esophageal, pancreatic, kidney, breast and colorectal cancers.

Foods That Fight Cancer

The American Institute for Cancer Research argues that no single food prevents cancer, but that compounds in a mostly plant-based diet may work together, and that such a diet limits the weight gain implicated in several cancers. It recommends filling two-thirds of the plate with plant foods.

Vitamin D prevents breast cancer - study

A meta-analysis of 33 studies found women with high vitamin D intake were 9 percent less likely to develop breast cancer, and those in the highest quantile of circulating 25(OH)D 45 percent less likely. The highest calcium intakes went with 19 percent lower risk.

Curry and turmeric help smokers with head and neck cancer

Researchers testing curcumin against head and neck squamous cell carcinoma cell lines found it blocked nicotine from activating cancer-causing cells, suggesting curry powder and turmeric might counter nicotine's effect in smokers. Presented at the 2009 AAO-HNSF meeting.
