Smoking increases bowel cancer risk

A study from Roswell Park Cancer Institute evaluated smoking and second hand smoking habits of 1,200 colorectal cancer cases and compared these to 2,400 malignancy-free matched controls. When removing the effect of smoke inhalation from second hand smoking partners they reported substantial increase in the odds of colorectal cancer for all smoking variables... Read more | Tips to quit


Behavioural change programmes after breast cancer increases exercise levels

An analysis of 14 unique behavior intervention trials for women with breast cancer between was published this month.  All interventions included moderate-intensity activities plus various behavioral change strategies. They all successfully increased physical activity levels. Two types programmes did particularly well: Highly structured interventions and interventions supported by phone counseling or e-mail.

Quitting smoking improve outcomes after prostate cancer 

Memorial Sloan Kettering Cancer Centre in New York evaluated 2,400 patients who underwent treatment for prostate cancer between 1988 and 2005. Although smoking has been previously shown to increase prostate cancer risk they found it is still important to give up because that those who continued to smoke during and after radiotherapy had double the prostate cancer specific death rate. Other studies have also shown smoking increased rectal damage. Clearly smokers after prostate should be strong counselled to quit. Read more | Tips to quit.

Insulin resistance increases breast cancer risk - overweight or not!

fat lady Insulin's role in breast cancer risk was invested in a study published by the American Diabetic Society. More than 3,300 women without diabetes, 497 of whom developed breast cancer over eight years were analyzed for their weight, fasting insulin levels and insulin resistance. Overweight women with high insulin had an 84% higher risk of breast cancer than overweight women with normal insulin but normal weight women with insulin resistance fared just as badly. It's excess insulin which is the problem not just being overweight.. read more

Bowel cancer rates rising in young adults 

  A study published in the Journal of Adolescent Oncology showed that despite bowel cancer rates generally falling by 1% per year, there is a worrying trend in young adults. They found, that between that colon cancer rates have been rising by 2.7% among those under 50 year olds. Authors felt this may reflect a poor lifestyle earlier in life and are concerned that public health guidelines for bowel cancer rarely include this group. Read more

Friendly dogs increase quality of life amoung palliative cancer patients

A study involving patients receiving palliative radiotherapy or chemotherapy for Head and Neck cancer was conducted by Mount Sinai Beth Israel Medical Center in New York. They showed that patients' benefited from regular friendly dog visits during which they petted and formed a bond. Despite declines in physical and functional well-being as treatment progressed, there were significant improvements in overall quality of life as well as social and emotional well-being scores. Publish in The Journal of Community and Supportive Oncology. - more


Coffee - now found to reduce risk of melanoma

coffee A study, by the National Cancer Institute, asked 3.5 million people their coffee drinking and found that moderate coffee intake was linked with a 20% reduced risk of malignant melanoma even when factoring out other risks such as ultraviolet radiation, body mass index, age, sex, physical activity, alcohol intake and smoking. Previous studies have also shown that the polyphenols in coffee reduces the risk of non-melanoma skin cancer - more

Excess selenium supplements increases prostate cancer relapse rates

An further analysis of The Health Professionals Follow-up Study looked at selenium intake after prostate cancer. Although an early trial showed selenium deficiency increased the risk, the SELECT study showed selenium supplements actually increased risk especially if combined with vit E. Now this study of 4,459 men showed selenium supplementation of ≥ 140 μg/d after prostate cancer was linked with a 2.6-fold greater risk of relapse (abstract). This confirms you should only take selenium to correct a known deficiency - measure your selenium levels


Exercise produces cancer fighting chemical  

power walking A chemical released from muscles after vigorous exercise called irisin has been added to triple negative breast cancer cells in laboratory by scientists at University of New Mexico. irisin reduced the number of malignant cells by 34% compared with untreated cells, but had no effect on normal cells. What's more cell migration (a marker of metastasis) reduced by 51%. It also enhanced the killing effect of the chemo agent Adriamycin - The study in the International J of Cancer supports the clinical data that exercise improves outcome after breast cancer - read more about exercise after cancer


Raw veg containing myrosinase enhances benefits of broccoli  
A study of broccoli, presented in the American Institute for Cancer Research, showed that the enzyme myrosinase enhanced the formation of sulforaphane from isothiocyanate. The trouble is that microwaving and boiling broccoli for more than 5 mins damaged myrosinase. Fortunately, they also found that individuals who ate a second raw cruciferous vegetable or other foods which contained myrosinase (mustard, radish, arugula, wasabi) restored the formation of sulforaphane. As broccoli is one of four ingredients of Pomi-T it may be a good idea to take it with a bite of radish although manufacturers are currently investigating whether drying and grinding broccoli into powder damages myrosinase - more


Certain probiotics shown to protect us from "colds" 

  A growing interest has been directed towards the role of probiotics in preventing upper respiratory track infections. Several studies have now confirmed that their regular intake reduces the incidence and severity of colds. For most of us this is a troublesome annoyance but of those with other illnesses this could lead more to serious consequences. For athletes colds can interfere with their training programme - hence why probiotics are recommended to the Australian national team. It is very important however to take a reputable brand with high manufacturing standards - read more

Measure and plot your PSA doubling time (PSAdt)

 This application is useful for doctors and patients alike as it quickly and accurately calculates the rate of rise of two or more PSA blood measurements over time - more important measurement than an isolated single level.

This is particularly useful for men with prostate cancer managed with Active Surveillance or experiencing a PSA relapse after previous treatments. The PSA doubling time over any period of time is displayed in an easily readable graph so one can accurately see if it is shortening (bad) or lengthening (good) in response to lifestyle changes or oral supplements such as Pomi-T. The graph can be updated with each blood test and the results emailed to your home computer or doctor - read more
