Often times, #Cancer prevention/treatment could seem like a tedious affair especially when it comes to separating the cures from the causes. Foods especially prove tedious to weed out since they contain both good and bad ingredients when formulating a cancer-free diet.

Fortunately, there are well researched resource lists -- like this one -- that will make the job easier. And this #Top 5 list doesn't cover just any cancer fighting foods; it covers those that are deemed as "Cancer Fighting #Super Foods."

5. Lemon

More and more, #cancer research is making the lemon out to be a miracle fruit.

You've probably already heard that the vitamin C contained in citrus fruits can eliminate colorectal cancer. But this is only the beginning.

Further research shows that the properties contained in lemon peels could also eradicate malignant cells found in many other cancers. Although not fully proven, this could be one of the healthiest, cheapest and simplest alternatives to cancer treatment at your fingertips.

4. Tuna

Those who aren't fans of fish need to reconsider a new diet. The aquatic creature can be a deterrent for #cancer. Tuna especially. The truth about fish is their bodies can supply omega 3 fats which are essential for preventing heart disease and inflammation which is linked to cancer.

Besides that, fish are also a great at inhibiting cancer growth in the human body. Hence, the only excuse a person could have for skipping out on a nicely prepared tuna fish is an allergy.

3. Onions

As a proud member of the Allium family, onions provide many health benefits towards fighting off diseases. Besides boosting the immune and cardiovascular systems, onions can also serve to fight and prevent cancer.

Research shows that the more people consume allium vegetables, the less likely their bodies would develop cancers in their ovarian, colorectal and laryngeal regions. This may be due to the fact that these vegetables stimulates glutathione production that detoxifies the body.

2. Nuts

Nuts are a wonderful super food for staving off or even fighting cancer directly.

That's because these nuts contain laetrile (B17) which is notorious for its ability to effectively eliminate cancer cells. Laetrile is also good at improving the immune system.

Another interesting fact about laetrile was that its effectiveness was well known for several millennia -- ancient Chinese history provides proof of the substance being used in tumor treatment. And for the past 40 years or so, laetrile's cancer fighting power was even a well kept secret as part of a cover up by the FDA.

1. Mushrooms

For ages, edible mushrooms have been sourced for their nutritious properties. So it seemed it would only be a matter of time before the question on whether mushrooms could also yield cancer fighting solutions popped up.

And it was true.

Mushrooms like Maitake, Turkey Tail, White, and more have been proven to possess anti-cancer properties. They can enhance the immune system, stop the growth of cancer cells and even reduce the size of tumors. Mushrooms can even activate natural killer cells to seek out and reduce metastasis (secondary growth) of malignant cells.
