Eating 4 or fewer servings of red and processed meat a week appears to reduce the risk of further complications and relapses occurring in people with diagnosed colorectal cancer.
Investigators from the American Cancer Society (ACS) found that survivors with consistently high intakes (about 4 servings/week or higher) before and after diagnosis had a 79% higher risk for colorectal cancer specific mortality than those with intakes consistently below the median.
The full study can be reviewed in the Journal of Clinical Oncology.
In conclusion, the authors noted that “Men and women who consistently ate the most red and processed meat before and after diagnosis had a statistically significant higher risk of death as a result of CRC, compared with those who consistently ate the least red and processed meat.”
Today the Ovarian Cancer National Alliance have released a free app designed to help women learn more about the signs, risks, and symptoms of ovarian cancer, the app also tells you whether you should go and see a doctor.
The Ovarian Cancer Symptom Diary App allows women to learn more about the disease, answer risk factor questions, including use of hormone replacement and family history of cancer, as well as keeping a daily record of any ovarian cancer symptoms experienced, which include:
- Abdominal pressure, bloating, swelling or fullness
- Loss of appetite or feeling full quickly
- Pelvic/abdominal discomfort or pain
- Urinary symptoms (urgency or frequency)
If any of these symptoms are recorded for 14 days in any given month, the app will send an email to prompt the user to visit a doctor and be tested for the disease.

In our ongoing reporting of vitamin D related news stories, a soon to be published study (watch this space) adds support for the need to consider higher vitamin D intake levels in individules with grerater body mass. Several studies have already described an inverse relationship between serum vitamin D3 and cancer risk. Furthermore, higher plasma D3 levels are associated with improved survival in prostate, breast, lung, colorectal, and ovarian cancers. Interestingly, a better vitamin D status at the time of diagnosis and treatment, adjusted for season of diagnosis, has been shown to improve survival buy several factors are involved in the regulation of vitamin D3. The most accacpted factors are known age, gender, race, dietary intake, season and sunlight exposure. However, a new regulating factor is now making the news.
Recently, the relationship between obesity and vitamin D status has been investigated suggesting decreased bioavailability of D3 from skin synthesis and dietary sources in association with obesity. In studies of obese adolescents in the United States, vitamin D deficiency has been correlated with greater weight and elevated BMI. In the healthy adolescent population the distribution of fat was found to be associated with vitamin D status with obese adolescents being found to have D3 deficiency.
The association between vitamin D and obesity assumes even greater importance in cancer, given the alleged role of both obesity and vitamin D in cancer risk and survival. Although it has been recommended that adiposity (fatness) should be considered when assessing vitamin D requirements in obese patients, current dietary recommendations do not take into account a person’s BMI and it remains unclear whether the dose of vitamin D required for repletion is related to the degree of obesity.
There are to date, no studies which indicate whether the presence of malignant disease compounds these issues. In the new study, researchers have addressed the first aspect of this question by investigating the relationship between serum D3 and BMI in a large and diverse population of cancer patients at a comprehensive cancer center. The study found that obese cancer patients (BMI >=30 kg/m2) had significantly lower levels of serum D3 as compared to non-obese patients (BMI <30 kg/m2). The message from this new work suggests that BMI should be taken into account when assessing a patient’s vitamin D status and more aggressive vitamin D supplementation should be considered in obese cancer patients.
When the paper is published we will post a link.

On Thursday evening over in the States, NBC Nightly News did a story on Inositol and Lung Cancer, treatment and prevention and announces that inositol has now been entered into clinical trials in the USA, see http://tr.im/V6DK
As a reminder, IP6 (Inositol Hexaphosphate) and Inositol work better TOGETHER than either one alone. Inositol Hexaphosphate is simply Inositol with 6 (Hexa) Phosphate molecules attached. I believe they mention inositol phosphate pools within the cells during this interview. The inositol phosphate pools are largely responsible for cell signaling (intercellular communication) which controls DNA expression, replication and a host of other activities vital to healthy, normal cells. We believe by restoring the IP-1,2,3,4,5 and 6 plus the additional inositol leads to the results they saw in this study. Not to mention all the other studies on IP6 & Inositol in many other types of cancer.
