You may not be able to control factors such as age and genetic makeup, but you can change your diet and exercise habits to further reduce the risk. Read on for what you can do, starting now:

Manage Your Weight

A clear link has been established between obesity and breast cancer, so find the appropriate weight for your age and height, and maintain it.

Stay Fit

Regular exercise can help you maintain that healthy weight, so set aside at least 30 minutes each day for physical activity.

Cut The Fat

Research has found a slight decrease in breast cancer risk for women on low-fat diets. Limiting your fat intake can also help control your weight. No more than 35 percent of your daily calories should come from fat, and be sure to reduce your consumption of foods high in saturated fat. Eat a balanced diet rich in fruits and vegetables, whole grains, and lean protein, to maintain your weight.

Limit Alcohol

British researchers have found an increase in breast cancer for women who consume one drink a day, so either eliminate alcohol altogether or restrict yourself to an occasional glass, now and then.

Eat Flaxseed

Your breast cancer risk is linked to the amount of estrogen you're exposed to over your lifetime. Phytoestrogens, which are naturally occurring compounds, lower circulating estrogens in your body. Flaxseed contains a high level of a phytoestrogen called “lignan”, which seems to decrease estrogen production and could even inhibit the development of some breast cancers. So consider adding flaxseed to your morning cereal, muffins, and breads.


Research has identified a link between smoking and breast cancer—and that risk increases with the number of years a woman smokes. An American study found that women who smoked a pack a day for eleven years had a 30 to 40 percent increased risk compared to women who did not smoke. If you don’t smoke, then don’t start, and if you do smoke, stop—with the assistance of your doctor.

Take Matters Into Your Own Hands

You may already know this, but it bears repeating: check your breasts. Get to know their texture and density, so that you can identify any changes. Click here for how to perform this vital test. Be sure to have your doctor check your breasts for you during your annual check up. Lastly, women 40 years and over should begin yearly mammograms.

Loaded with vitamins C and B, potassium, folic acid and iron, the pomegranate

پزشکی امروز

This exotic fruit, whose juice has gained in popularity since it was first marketed in North America, is considered a superfruit. It’s loaded with vitamins C and B, potassium, folic acid and iron. And each of the crunchy, edible seeds is a source of fibre.

  Preliminary studies suggest pomegranates may contain nearly three times the antioxidants of green tea or red wine, and may play a role in the prevention of cancer and heart disease.

  Available from October through January,  pomegranates are packed with hundreds of red arils, translucent capsules filled with a sweet or tart juice and a tiny seed. A ½ cup of arils has just 80 calories, but it packs a nutritional wallop: 5 grams of fibre and 180 mg of potassium.

  A pomegranate’s arils can be eaten alone, or used as a garnish. Sprinkle them on salads or mix them into your oatmeal or yogurt. You can also add them to baked goods, such as muffins or cookies.

  Some Like it Raw

  The pomegranate has a thick reddish skin and hundreds of seeds. The tiny arils are surrounded by a bitter, inedible white pulp.

  It’s a labour-intensive fruit, but now that we know how nutritious it is, it’s probably worth the effort to crack one open and give it a try.

  To eat a pomegranate, first cut off the top of the fruit, then score the rind with a knife (as you would to peel an orange). Place it in a bowl of water—to prevent the pomegranate juice from squirting—and break it into sections. Push the arils out, separating them from the pith and other membranes. The arils will sink while the membranes will float to the top. Simply strain the water and the arils are ready to eat, seeds and all.

  You can store fresh unopened pomegranates at room temperature for a week or two, or place them in the crisper, where they’ll keep for over a month. Fresh arils can be frozen for up to a year, in an airtight bag.

Mouth cancer has the same meaning as oral cancer - it is cancer that occurs in any part of the mouth; on the tongue's surface, in the lips, inside the cheek, in the gums, in the roof and floor of the mouth, in the tonsils, and also the salivary glands.

Mouth cancer is a type of head and neck cancer, and is often treated similarly to other head and neck cancers.

34,000 Americans are diagnosed with oral or pharyngeal cancer each year, and about 8,000 die (annually). In England and Wales about 2,700 cases of oral cancer are diagnosed annually. Oral cancer kills approximately 920 people each year in England and Wales. Most oral cancer cases occur when the patient is at least 40 years old. It affects more men than women.

At least 124,000 new cancers in 2008 in Europe may have been caused by excess body weight, according to estimates from a new modelling study. The proportion of cases of new cancers attributable to a body mass index of 25kg/m2 or more were highest among women and in central European countries such as the Czech Republic, Latvia, Slovenia and Bulgaria.
The lead author of the study, Dr Andrew Renehan, told Europe's largest cancer congress, ECCO 15 - ESMO 34, in Berlin: "As more people stop smoking and fewer women take hormone replacement therapy, it is possible that obesity may become the biggest attributable cause of cancer in women within the next decade."
Dr Renehan, who is a senior lecturer in cancer studies and surgery at the University of Manchester (UK), and his colleagues in the UK, The Netherlands and Switzerland, created a sophisticated model to estimate the proportion of cancers that could be attributed to excess body weight in 30 European countries. Using data from a number of sources including the World Health Organisation and the International Agency for Research on Cancer, they estimated that in 2002 (the most recent year for which there are reliable statistics on cancer incidence in Europe) there had been over 70,000 new cases of cancer attributable to excess BMI out of a total of nearly 2.2 million new diagnoses across the 30 European countries.
The percentage of obesity-related cancers varied widely between countries, from 2.1% in women and 2.4% in men in Denmark, to 8.2% in women and 3.5% in men in the Czech Republic. In Germany it was 4.8% in women and 3.3% in men, and in the UK it was 4% in women and 3.4% in men.
Then, the researchers projected the figures forward to 2008, taking into account what was known about shifts in the distribution of BMI, the dramatic decline in women's use of hormone replacement therapy (HRT) from 2002 onwards following research that showed it increased the risk of breast cancer, and the wider use of PSA screening for prostate cancer in men.
They found that the number of cancers that could be attributed to excess body weight increased to 124,050 in 2008. In men, 3.2% of new cancers could be attributed to being overweight or obese and in women it was 8.6%. The largest number of obesity-related new cancers was for endometrial cancer (33,421), post-menopausal breast cancer (27,770) and colorectal cancer (23,730). These three accounted for 65% of all cancers attributable to excess BMI.
"I must emphasise that we are trying not to be sensationalist about this," said Dr Renehan. "These are very conservative estimates, and it's quite likely that the numbers are, in fact, higher."
The number of new cases of obesity-related oesophageal cancer was particularly high in the UK relative to the rest of Europe. "This country accounts for 54% of new cases across all 30 countries," said Dr Renehan. "This may be due to synergistic interactions between smoking, alcohol, excess body weight and acid reflux - and is currently an area where research is required."
Until 2002 when HRT use dropped dramatically following the results of the Women's Health Initiative Trial (USA) that showed an increased risk of breast cancer in women taking HRT, Dr Renehan said that HRT masked and diluted the effects of obesity on the incidence of breast cancer. "In women who used HRT it wasn't clear what proportions of breast cancers were caused by HRT or by obesity. In women who don't take HRT, the effect of obesity was much clearer. Now that far fewer women are using HRT, it is much easier to see the effect of obesity on the incidence of breast cancer, and also on endometrial cancer. Consequently, the proportions of these cancers attributable to obesity have increased."

Dr Renehan said that although European countries were taking steps to tackle the obesity epidemic, this study underlined the urgency of the task and the scale of the problems caused by increasingly overweight populations.

Dr Renehan's own research is trying to relate these epidemiological findings back to the biological mechanisms that are at work. His research uses the observed interactions between excess BMI and cancer risk to guide questions in the laboratory.

Men with low-risk prostate cancer (CaP) who are candidates for active surveillance (AS) often choose definitive therapy due to anxiety over their untreated cancer. In the September 1, 2009 issue of Cancer, a group of researchers from the Netherlands assessed anxiety and distress during AS for CaP.

This study included patients enrolled in the protocol-based AS program of the international prospective Prostate Cancer Research International: Active Surveillance (PRIAS) study. Inclusion criteria were PSA <10ng/ml, PSAD <0.2ng/mL/mL, nonpalpable or localized CaP, no more than 2 positive needle biopsy cores and a Gleason score of <6(3+3). Between 2007 and 2008 150 men who entered the PRIAS study received a QoL questionnaire. Decisional conflict on the choice for AS was assessed with the Decisional Conflict Scale (DCS) which consists of 16 items with 5 response options each. A score of 100 indicates maximum decisional conflict, scores <25 are associated with implementing the decision and scores >37.5 are associated with decision delay or feeling unsure regarding implementation. Other parameters assessed included depression, general anxiety, CaP-specific anxiety, general health, personality, involvement in the physician decision-making process, and knowledge of CaP.

The response rate was 129 of 150 questionnaires sent (86%). DCS scores were lower than the reference value for decision delay or feeling unsure regarding implementation, 37% (81 of 129 respondents) also had scores below the reference value associated with problems in implementing the decision, 92% (119 of 129 men) had scores lower than the reference value for depression, 83% (107 of 129 men) had scores lower than the reference value for clinical anxiety, and 93% (120 of 129 men) had scores lower than the reference value for clinically significant CaP-specific anxiety. A total of 83 men (64.3%) scored below the reference value on all 4 main variables.
