Among 89 Merkel cell carcinoma patients whose blood was tested within three years of diagnosis, 65 percent were vitamin D deficient. Deficiency was associated with larger tumors at diagnosis and with nearly twice the likelihood of metastatic recurrence.

Fruit and vegetables may reduce colorectal cancer risk
An Italian case-control study of 1,953 colorectal cancer patients and 4,154 hospital controls found total dietary antioxidant capacity inversely related to risk: those in the lowest fifth were about 30 percent more likely to be diagnosed than those in the highest.

Fruit, eggs and tea lower lung cancer risk, passive smoking ups the risk
A case-control study of 226 women with lung cancer and 269 controls in Fujian Province, China found fruit, egg and tea intake inversely associated with lung cancer, while passive smoking and exposure to cooking oil fumes were tied to higher risk.

Prostate Cancer News: Dietary Fiber Prevents Aggressive Prostate Cancer
Among 930 black and 993 European American men in a North Carolina-Louisiana study, those in the top third of dietary fiber intake were 39 percent less likely to have aggressive prostate cancer, with the stronger association among European Americans.

Plant-derived micronutrients help prevent ovarian cancer
Three studies are summarized as suggesting plant-derived antioxidants may help prevent ovarian cancer. In a New Jersey case-control study of 205 cases and 390 controls, women in the highest tertile of dietary selenium were 59% less likely to develop the disease.

Breast cancer news mini review 2: Modifiable factors and breast cancer
The second part of a roundup of recent breast cancer studies: pomegranate juice and its compounds inhibited processes involved in metastasis, Allium sivasicum extract proved toxic to breast cancer cells and slowed growth in rats, and adequate selenium intake was linked to lower risk.

Breast Cancer News Mimi review (1) - modifiable factors and breast cancer
A roundup of recent studies: high folate intake was tied to worse survival in ER-/PR- breast cancer, a diet high in fruit and vegetable oil came with 26 percent lower all-cause mortality in patients, and vitamin C may delay progression, based on mouse work from the Dr. Rath Research Institute.

How to prevent liver cancer without using hepatitis B vaccine?
T. Colin Campbell's mouse studies found animals fed 20 percent soy protein stayed healthy after aflatoxin dosing while those fed 20 percent casein died early, and that hepatitis B virus did not damage the livers of mice on a plant-based diet.

Aspirin cuts risk of colorectal cancer
Peter Rothwell writes in Cancer Research that trial evidence shows daily aspirin cuts recurrent colorectal adenoma risk by 17 percent and advanced adenoma by 28 percent, with about five years of use tied to a 30 to 40 percent lower risk of colorectal cancer death. Major bleeding is a risk.

How much vitamin d per day should I take to prevent cancer?
Michael Holick of Boston University Medical Center writes that serum 25-hydroxyvitamin D of 40 to 60 ng/mL is needed for an anticancer effect, reached by 600 to 1,000 IU a day in children and 1,500 to 2,000 IU in adults. He says most cells can convert vitamin D to its active form.

Foods that help prevent cancer
A rundown of foods credited with lowering cancer risk: sweet potatoes, which contain DHEA; kiwi, with roughly 200 mg of vitamin C per 100 grams; pumpkin, rich in vitamins A and C and fiber; and eggplant, whose solanine and cucurbitacin have shown chemopreventive activity.

Pomegranate prevents, antibiotic causes skin cancer - study
A case-control study in the British Journal of Dermatology confirmed UV rays as the leading skin cancer risk. It also linked ciprofloxacin use to 67 percent lower basal cell carcinoma risk, thiazide diuretics to 66 percent higher squamous cell risk, and pomegranate to lower risk of both.

Omega 3, omega 6 fatty acids linked to breast cancer risk
Among 1,000 Mexican women with breast cancer and 1,074 controls, high omega-6 fat intake tracked with 92% higher risk in premenopausal women, while high omega-3 intake went with 42% lower risk only among obese women. No overall omega-3 association emerged.

Eggs, chicken, red meat boost advanced prostate cancer risk
Following 27,607 men from 1994 to 2008, Harvard researchers found those eating 2.5 or more eggs a week were 81% more likely to develop lethal prostate cancer. Among men already diagnosed, heavy poultry intake tracked with 69% and red meat with 45% higher risk of lethal disease.
Cancer
Eating meat increases aggressive prostate cancer risk
In a study of 470 men with aggressive prostate cancer and 512 controls, Punnen's team tied high ground beef and processed meat intake to the disease. Grilled or barbecued and well-done meat carried the risk; rare or medium ground beef showed no association.

Drinking milk in early life linked to advanced prostate cancer - Milk Nutrition News
Tracking 8,894 Icelandic men from 1967 to 2009, J.E. Torfadottir's team found those who drank a lot of milk in adolescence were three times as likely to develop advanced prostate cancer as infrequent drinkers. Rural early residence carried 29% more risk.
Cancer
Carcinogens in cooked meat linked to colorectal cancer
Comparing 413 colorectal adenoma cases with 796 controls, Zurich researchers found risk rose with intake of PhIP, MeIQx and DiMeIQx, heterocyclic amines formed in grilled, fried and roasted meat. SULT1A1 phenotype modified the MeIQx effect; other gene variants did not.

Dietary fiber cuts breast cancer risk
A Chinese study of 557 breast cancer cases and 536 controls found premenopausal women in the highest quartile of fiber intake were 62% less likely to have the disease, with no reduction among postmenopausal women. A review of 16 prospective studies found a 7% lower risk.
