Building Your Strength Against Cancer - The Antioxidant Defenses
Oxygen is essential to life. But, as oxygen is used surrounded by the body, some of the oxygen molecules become very unstable. These unstable oxygen molecules, call free radicals, can attack cell membranes and even wreck the DNA (genetic code) in the nucleus of the cell. Damage to DNA is the inauguration of cancer.

Fortunately, the foods we eat can assistance protect our bodies. Antioxidants, including vitamin C, vitamin E, beta-carotene, selenium, and others, can neutralize the damaging effects of oxygen.

What are some possible solutions as to why my spell is this late?

Not sure going on for specifically breast cancer, but the best diet change for reducing the chanse of getting cancer overall is going lacto-vegetarian (60% reduced risk), and the next best article is going vegetarian (40% reduced risk).

Is this possible?

I can give you this advice: Milk is heavily burdened with equal hormones that are in our bodies at puberty. The cows are injected near it to help them produce more milk. The problem is, humans shouldn't smoothly have it at adjectives, let alone at such huge quantities contained by adulthood. It have been shown that these hormones try to produce additional growth contained by our bodies, and can lead to forms of cancer - including breast cancer. I would speak, stay away from dairy, it is only cause more problems.

When is the safest time to have sex?
