breast cancer and fat

Answered on September 12, 2014

A doctor told me that dietary fat is strongly linked to breast cancer. I'm not sure anymore what to believe of what doctors tell me. Could you in the know weigh in?

Last time I went it was to a first baptist, that's the type I went to while growing up.

Ask your doctor to print out these "studies" to which he's referring.

Great points. I also started this adventure with cancer in mind. After reading Taubes "Good Calories Bad Calories" I thought I'd go 100% cold turkey on sugar just to see if I could do it, with the purpose of long term cancer prevention. All the other effects (weight loss, mood, energy, etc) were a surprise to me.

Ask him for the studies/meta analyses or it didn't happen.

There's definitely some correlation.

1: Excess body fat can make your body produce extra estrogen (http://www.livestrong.com/article/164671-estrogen-obesity/) which can lead to estrogen dominance, which could lead to breast cancer: http://www.envirocancer.cornell.edu/FactSheet/General/fs10.estrogen.cfm (please note that in the study, they say eating a diet low in fat will help estrogen levels, but we here know better. I included this to show that even conventional wisdom sees a relationship between estrogen and breast cancer. They just get it wrong on how to deal with it.)

2: Cancer growth and body fat are driven by some of the same factors. Excess sugar in the blood (refined carbs and sugars) increases insulin levels. Insulin drives fat storage. Also, there are 10X as many insulin receptors in cancer cells than in normal cells, which means that lots of sugar and insulin is the perfect food for cancers. When a conventional doctor say's there's a correlation between being fat and cancer, they're not thinking that they're both caused by the same unhealthy diet. Perhaps they should get their biology 101 book and remember what insulin does and what triggers it.

Please note, I'm here to prevent cancer, not lose weight. The weight loss is great, but for me, lowering my refined carbs and eating natural is about fighting cancer.

Just google "breast cancer and paleo diet" and start reading. Most of those "in the know" will tell you that the research is starting to show sugar as the main culprit behind cancer. Could there be a link with fat? Maybe, if you are consuming that fat with sugar...

Here is a great article from Mark Sisson that outlines this idea; notice that the mice being fed "fat" are really being fed SUGAR:

I wouldn't be surprised if the doctor is confusing dietary fat and body fat since they are both called "fat." He may be mistaken because high body fat levels put you at greater risk for cancer. Since SAD people think that eating fat will definitely make you fat, regardless to total calorie intake or sugar intake, he probably jumped to the conclusion that eating fat will give you cancer.

If my doctor told me fat causes cancer without showing me the studies he's referring to or the meta analyses, I'd take his opinion with the same amount of weight as if my preacher told me to give him 10% of my wages or I'm going to hell. It's pure conjecture without the supporting literature, if he can't provide it his OPINION is just that, his opinion.

If he gives you some studies, post them here and I among others I'm sure would be happy to either critique it or point you to other blogs where it's been critiqued.

Read these articles (if you have problems linking to them, just google / medscape calorie restriction cancer \ and they should show up and be clickable): http://www.medscape.com/viewarticle/757713 http://www.medscape.com/viewarticle/778613

??? The hypothesis that suppressing carbohydrates could suppress or slow cancer growth is supported by a lot of laboratory science. The pair explain that complex carbohydrates are ultimately digested as glucose, which can cause tumor cells to proliferate.

"First, contrary to normal cells, most malignant cells depend on steady glucose availability in the blood for their energy and biomass-generating demands, and are not able to metabolize significant amounts of fatty acids or ketone bodies due to mitochondrial dysfunction," they write. In other words, cancer cells thrive on glucose and starve on fats and ketones, which are food-derived energy units that are plentiful in low-carbohydrate diets. The commonplace advice to avoid dietary fat is not a good recommendation to give cancer patients. "They should eat a lot of fat and avoid sugar," Dr. Freedland noted. ???

I personally think it is tantamount to malpractice for a Dr. or nutritionist to advise avoiding dietary fat to avoid breast cancer without telling you to absolutely cut out sugar. I did carb restriction (not fat restriction) and a couple fasts before my lumpectomy and shrank a breast cancer tumor by a couple millimeters all around. I'm acquainted with a woman who did not have surgery and simply shrank her tumor down (from 2.7 cm to .8cm in 3.5 months) and manages it with diet (keto to carb restricted) and iodine intake - she is now 5 years out from diagnosis. While that wouldn't be (and wasn't) my choice, I find it pretty fascinating. You could take a look at breastcancerchoices.org also for some interesting reads. And take note of that article on Mark's Daily Apple posted by RK - that's a classic! The so called "high fat diet" was 31% sucrose.
