A Brief Overview of Breast Cancer Distribution
Breast cancer affects one in every eight women in the United States. Over 54 percent of nearly 500,000 breast cancer patients in one analysis had tumors diagnosed in the upper-outer quadrant of the breast. [1]In a hemispherical breast, the UO quadrant comprises only 25 percent of the breast volume. In a pendulous breast, that proportion of UO volume compared to total volume is even less, as the bulk of the breast mass in a pendulous breast is below (“inferior to” in anatomical language) the nipple line.
The predominance of breast tumors in the UO quadrant, therefore, defies a random distribution by over 200 percent (54.3 percent / 25 percent).
UO quadrant breast tumors generally have better outcomes than tumors in other areas of the breast. [2] It is possible that worse outcomes are seen with lower and medial breast tumors due to their being in an area that will less likely drain to axillary lymph and more likely drain to the internal mammary lymph chain. [3]
Lymph is one-third of the bodily fluid. It is a one-way circulatory system that collects debris from all over the body (the residuals from normal cell metabolism) into lymph nodes and transports it along lymph chains. Ultimately, this debris is deposited in the thoracic duct and then is taken out with the stool. The breast is a lymphatic dead end, so to speak, and part of the risk of breast cancer may be that the debris of cellular metabolism has a narrow path outward.
Why Are Most Breast Tumors in the Upper Outer Quadrant?
The breast is composed of about 50 percent to 70 percent fat and 30 percent to 50 percent glandular tissue. [6] That ratio is about 50-50 before menopause, and then after menopause, glandular tissue is gradually replaced by fatty tissue. The predominance of breast cancer in the UO quadrant has been attributed to the high density of glandular tissue in this area, and the glandular tissue develops and proliferates under the influence of hormones secreted by the ovaries, [7] predominantly estrogen, but also prolactin during pregnancy, with somewhat less influence by progesterone. Glandular tissue is where most breast cancers arise.However, toxic chemical residues enter into and remain in that tissue. This includes carcinogenic compounds in underarm deodorants, antiperspirants, or other cosmetics commonly used in that area, [8] which may be involved in the high incidence of breast cancer.
Parabens have been used in deodorants to suppress the growth of fungi, yeast, and bacteria. [9] Paraben compounds have been found intact in both normal and cancerous breast tissue [10] and have shown estrogenic effects on breast tissue. [11]
Aluminum and its salts are common ingredients in antiperspirant products. These compounds have been shown to alter estrogen action on tissues, as do other metals in the metalloestrogen category. [12]
Where Does Exercise Come In?
The largest surface of breast tissue, the interior (deep) side, overlays and contacts the pectoralis major muscle, which is more than 100 centimeters squared in the adult woman or somewhat larger than the palm of the hand. Pectoralis major and minor muscle tissue is thickest behind (deep to) the UO quadrant of the breast. Breast tissue and pectoral muscle are separated only by a thin 0.3-millimeter layer of pectoral fascia, so there is considerable surface area for interaction, as I will discuss below.Chest flies, cable chest pulls, and, to a lesser extent, bench presses, and pushups, all work the pectoralis muscles.
Exertion of muscles produces lactic acid. This lactic acid, along with the physical stress of exercise, is followed by a soreness sensation in the muscles used, especially over the next day or two. First, the lactic acid clears, and then the muscles undergo repair, regeneration, and even proliferation, as the muscles become bigger and stronger.
Lactic Acid Benefit Against Cancer
Nobel Prize biochemist Otto Warburg showed that cancerous cells are able to quickly convert an excess amount of sugar into lactate (lactic acid). It has been observed since Warburg’s time that sugar fuels cancer growth and is its primary fuel, and PET imaging makes use of this fact. [16] The conversion of sugar to lactate (lactic acid) is the body’s way of disposing of a sudden and large amount of sugar, such as from a soda or dessert, in a way that helps prevent a hyperglycemic crisis. Senior research scientist Stephanie Seneff of MIT calls this quickly converting a large amount of sugar to lactate the “cancer machine.” Cancer arises as an (undesirable) solution to a more immediately urgent problem of intolerably—even dangerously—high levels of dietary sugar.Stop a Chemical Reaction by Adding End Product
This principle is also well-known in pharmacology. Just as orally dosed estrogen (hormone replacement therapy) has been seen to reduce the body’s own estrogen production, so, too, are the effects of lactic acid production through physical activity expected to inhibit lactic acid production by other means—in this case, by cancerous activity.This is our goal with the cancer machine: to slow it down to an extent in which continued cancer cell survival is no longer viable or to make it stop altogether.
My Theory
Pectoral exercises add lactate adjacent to breast tissue, which, by Le Chatelier’s Principle, places a biochemical obstacle in the cancer machine. This results in depriving cancer of a reason to exist (at least in that area), particularly in the upper outer quadrants but also throughout the deep breast tissue.Starting Pectoral Exercises
Chest flies are often done starting with 5-pound weights, one in each hand, while lying face up, bringing the hands apart, and then raising them to meet in the middle. The elbows are kept somewhat bent, and the motions are done smoothly and slowly. Anywhere from 10 to 20 repetitions are done at a time. Weight is often increased with time to 10 or 15 pounds in each hand. Rest days are often incorporated, and exercises are usually done once or twice per week. A sore sensation can be expected the following day in these muscles while the lactic acid buildup and microtears of muscle tissue are repaired.The purpose of these exercises is to add an end product to an unwanted chemical reaction: glucose to pyruvate to lactate (which is the cancer machine), in order to give cancer no more reason to exist, at least not in the breasts.
