Vitamin D may reduce cancer risk, breast cancer mortality

Apart from building healthy bones, vitamin D also may reduce cancer risk as well as breast cancer mortality, especially in women with a lower body mass index.

BS| Breast cancer remains the most common cancer in women worldwide and is the leading cause of death from cancer in women. Reproductive risk factors such as early onset of puberty, late menopause, later age at first pregnancy, never having been pregnant, obesity, and a family history have all been shown to be associated with breast cancer development.

The role of vitamin D concentration in the development of breast cancer, however, continues to be debated.

Researchers involved in the study concluded that postmenopausal women had an increased risk of vitamin D deficiency at the time of their breast cancer diagnoses, associated with higher rates of obesity than women of the same age group without cancer.

Similar studies also have previously demonstrated a relationship between vitamin D and breast cancer mortality. Women in the highest quartile of vitamin D concentrations, in fact, had a 50% lower death rate from breast cancer than those in the lower quartile, suggesting that vitamin D levels should be restored to a normal range in all women with breast cancer.

Study reports risk of rare adverse outcomes from breast implants

According to a study, silicone breast implants could increase the risk of several rare adverse outcomes in women.

“We are reporting an analysis of the largest prospective study to date on silicone breast implant safety,” commented Mark W. Clemens of The University of Texas M.D. Anderson Cancer Center, Houston.

“We are sharing critical information on complication rates and rare associations with systemic harms. This data gives women important safety information about silicone breast implants to have real expectations and to help them choose what is right for them,” added Clemens.

Women receiving silicone implants were at increased risk of several rare harms compared to the general population. The elevated risks included three conditions classified as autoimmune or rheumatologic disorders: Sjogren’s syndrome, with a risk about eight times higher than in the general population; scleroderma, a seven-fold increase in risk; and rheumatoid arthritis, about a six-fold increase in risk.

“These findings are associations compared to the general population and determining why these associations are observed or any causation requires further study,” said Dr. Clemens.

Physical activities can reduce risk of cancer

A healthy diet and physical activities with no alcohol consumption can help in reducing overall cancer risk besides also lowering breast, prostate and colorectal cancer risks.

Researchers at the American Association for Cancer Research analysed the nutritional scores which showed the biggest benefit from a diet that discourages alcohol and reduces the risk of cancer.

The researchers estimated that in developed countries, around 35 per cent of breast cancers and 45 per cent of colorectal cancers could be avoided by better adherence to nutritional recommendations. It is, therefore, very important to investigate the role of nutrition in cancer prevention.

This study evaluated three previously validated nutritional recommendations: The WCRF/AICR score; the Alternate Healthy Eating Index; and the French Nutrition and Health Program-Guidelines Score, plus one relatively new index, the MEDI-LITE score, which measures adherence to a Mediterranean diet. Researchers found that all the diets were associated with some reduced risk, but the WCRF/AICR recommendations, developed specifically with cancer prevention in mind, had the strongest association with reduced risk…READ MORE
