Essential Oil Research – Limonene Has Great Potential For Breast Cancer

Lately I have been trolling through the vast quantities of research available, specifically looking at a particular little phytochemical known as limonene, found in high quantities in the peels of citrus fruit, and lesser quantities in the pulp of citrus fruit. I am excited to report that the research I have found indicates that limonene has great potential for breast cancer.

Limonene (pronounced lime-oh-neen) is classified as a cyclic terpene and in some research you will also find it referred to as d-limonene. A great way to obtain limonene is through citrus essential oils, more specifically lemon, mandarin, grapefruit, lime, tangerine and orange.

The research I am about to share is mainly about limonene, although citrus essential oils do contain other potent phytochemicals as well.

Research On Limonene Showing Anti-Cancer Potential

A lot of research has been done on limonene, it has been fairly actively studied since the 1970’s and possibly prior to that.  Those early studies done in the 70’s indicated that limonene inhibited the initiation phase of skin cancer.

This website is all about breast cancer, however, so I will limit the research I mention herein to limonene’s helpfulness for breast cancer.  Here we go.

A 2011 study 1 reported that limonene had potential chemotherapeutic properties, exhibited chemopreventive (meaning cancer prevention) effects, was an immune modulator and had anti-proliferative properties.

Another 2011 study 2, although done with lemon fruit extract (LE) and not limonene, showed that the extract induced apoptosis (anti-tumor activity), in vitro (meaning in the test tube), on MCF-7 breast cancer cells. MCF-7 cells are invasive ductal carcinoma with estrogen-receptor-positive (ER+) and progesterone-receptor-positive (PR+), and HER2 negative cells.  I have included this one because although the study didn’t specifically study limonene,  it is highly likely that the anti-cancer activity exhibited by the fruit extract was due to its limonene content.

One 2012 study 3 concerned itself with the safety and efficacy of using limonene via orange oil on the breast as an “alternative dosing strategy” and found that limonene is “bio available in mammary tissue after topical orange oil application in mice and this novel route of administration to the breast is safe and feasible in healthy women.”

A study done in 2013 4 on 43 actual women with breast cancer was very interesting. The 43 women were newly diagnosed with early stage breast cancer and about to undergo lumpectomies. The women took 2 gm of limonene daily 2-6 weeks prior to surgery. Limonene was found to “preferentially concentrate in the breast tissue” and reduced breast tumor cyclin D1 (a cell-cycle regulatory protein) expression that could lead to cell-cycle arrest and reduced cell proliferation.  Researchers felt that limonene should continue to be studied to establish its role for breast cancer prevention or treatment.  A subsequent study reported in January 2015 5 came to a similar conclusion, that limonene reduced cyclin D1 in patient tumor tissues.

One Iranian study reported in 2014 6 showed that a combination of an extract from lime peels and the cancer drug doxorubicin increased apoptosis (programmed cell death) in MCF-7 breast cancer cells.

Finally, a study reported in 2014 7 reflected that limonene had anti-inflammatory properties (always important in cancer, which is an inflammatory condition), exhibited “surprising” anti-angiogenesis properties (which relates to a tumor’s ability to invade surrounding tissue by sending out new blood vessels) and was useful for skin healing and tissue regeneration.

A Personal Note And A Bit Of A Soap Box

In the past, I have purposely held back from promotion of essential oils on this website – despite the fact that I have used them successfully myself for the past 16 years – indeed, as a representative for Young Living Essential Oils, we are specifically asked not to say that essential oils will treat or cure any disease. The United States Food & Drug Administration keeps a very close eye on the claims that essential oil representatives make.

I am not telling you to cure your breast cancer using essential oils. I would certainly not rely upon essential oils alone to do that job. But in combination with a holistic regimen of nutrition and other lifestyle changes, together with chemotherapy and radiation (should you choose to go that route) I believe that essential oils can be an extremely beneficial healing tool and chemopreventive aid.

New and exciting research is being released nearly daily now on the healing properties of essential oils and it is proof positive and undeniable. The authorities absolutely cannot keep a lid on this any longer and we are sick of being silenced.

Don’t Be Worried About Breast Size and Cancer Risk

The Huffington Post released a news story on July 5, 2012 titled Breast Cancer Risk Might Be Tied To Breast Size, Study Says.

The article (which you can read by clinking the link above) basically tells us that researchers at a commercial DNA testing service say they have found a handful of genes that help determine whether a woman spends her life as an A cup or a D AND that those genes might be tied to a woman’s risk of breast cancer.

Might being the operative word here.

Are we going to worry about this?  Are we going to spend one iota of our time being concerned?  NO, WE ARE NOT.

If you are, go back to my post of a couple days ago about The Biology of Belief.  Watch the one-hour video by Dr Bruce Lipton.  I will say it again – OUR GENES ARE NOT OUR DESTINY.

Here’s What We Do Need To Concern Ourselves With

In order to keep ourselves healthy, there are several things we definitely need to do.  As the article mentions (and I do agree with this), obesity is a risk factor for breast cancer, particularly after menopause.  So we need to keep our weight down.

We also need to build rock-solid immune systems so that disease can’t get a foot in the door.  If you need to know how to do this, contact me.

Studies have also suggested that women with dense breasts are up to 5 times more likely to develop breast cancer, but nobody seems to know why.  I don’t worry about that either.  I use certain essential oils to help keep myself healthy.  See my page Essential Oils For Overall Health and Specific Health Problems.

For more information, sign up for my newsletters and download my two free e-books that will (a) help you get through breast cancer if you are going through it, or (b) help you to reduce your risk of breast cancer.

By the way, while I was doing research for this article, I discovered that people are obsessed with breast size (no surprise there).  Apparently there were 1,300 worldwide Google searches on Angelina Jolie’s breast size.  Really?  People need to find something better to do with their time!  Just sayin’…
