How to prevent Breast Cancer

I found this article useful. I suppose it is good for any cancer but especially for women, mammogram may not something you should do, according to the article. It makes sense to me.

Almost 68% of Women over 40 Have Fallen for This Trap by Dr Mercola.

What Really Will Reduce Your Risk of Dying from Breast Cancer?

Breast cancer is the most common cancer among U.S. women, and one in eight will be diagnosed with it during their lifetime. Unfortunately, the aggressive push for mammography has many women equating actual preventive measures (e.g.  lifestyle, diet and nutrition changes, as well as avoiding chemical exposures) with annual breast screenings, which do nothing to prevent cancer, and may actually contribute to it.
Unfortunately, medical organizations like The American Cancer Society do very little to spread the word about the many ways women can help prevent breast cancer in the first place.
A healthy diet, regular physical exercise, and an effective way to manage your emotional health are the cornerstones of just about any cancer prevention program, including breast cancer.
The following lifestyle strategies will also help to further lower your risk:

• Radically reduce your sugar/fructose intake. Normalizing your insulin levels by avoiding sugar and fructose is one of the most powerful physical actions you can take to lower your risk of cancer. Unfortunately, very few oncologists appreciate or apply this knowledge today. The Cancer Centers of America is one of the few exceptions, where strict dietary measures are included in their cancer treatment program. Fructose is especially dangerous, as research shows it actually speeds up cancer growth.
• Optimize your vitamin D level. Ideally it should be over 50 ng/ml, but levels from 60-80 ng/ml will radically reduce your cancer risk. Safe sun exposure is the most effective way to increase your levels, followed by safe tanning beds and then oral vitamin D3 supplementation as a last resort if no other option is available.
• Maintain a healthy body weight. This will come naturally when you begin eating right for your nutritional type and exercising using high-intensity burst-type activities like Peak Fitness. It’s important to lose excess weight because estrogen, a hormone produced excessively in fat tissue, may trigger and/or feed breast cancer.
• Get plenty of high quality animal-based omega-3 fats, such as those from krill oil. Omega-3 deficiency is a common underlying factor for cancer.
• Avoid drinking alcohol, or limit your drinks to one a day for women.
• Breastfeed exclusively for at least six months. Research shows this will reduce your breast cancer risk.
• Watch out for excessive iron levels. This is actually very common once women stop menstruating. The extra iron actually works as a powerful oxidant, increasing free radicals and raising your risk of cancer. So if you are a post-menopausal woman or have breast cancer you will certainly want to have your Ferritin levels drawn. Ferritin is the iron transport protein and should not be above 80. If it is elevated you can simply donate your blood to reduce it.
• Avoid charring your meats. Charcoal or flame broiled meat is linked with increased breast cancer risk. Acrylamide—a carcinogen created when starchy foods are baked, roasted or fried—has been found to increase breast cancer risk as well.
• Avoid unfermented soy products. Unfermented soy is high in plant estrogens, or phytoestrogens, also known as isoflavones. In some studies, soy appears to work in concert with human estrogen to increase breast cell proliferation.
