The female breasts and the male prostate are both sources of fascination, curiosity, and fear. Hidden deep in the pelvis at the crossroads of the male urinary and reproductive systems, the prostate is arguably man’s center of gravity. On the other hand, the breasts—with an equal aura of mystery and power—are situated in the chest superficial to the pectorals, contributing to the alluring female form and allowing ready access for the hungry infant, curiously an erogenous zone as well as a feeding zone.

Interestingly enough, the breasts and prostate share much in common, both serving important “nutritional” roles. Each functions to manufacture a milky fluid; in the case of the breasts, the milk serving as nourishment for infants and in the case of the prostate, the “milk” serving as sustenance for sperm cells, which demand intense nutrition to support their arduous  marathon journey traversing the female reproductive tract.

Breasts are composed of glandular tissue that produces milk, and ducts that transport the milk to the nipple. The remainder of the breast consists of fatty tissue. The glandular tissue is sustained by the female sex hormone estrogen and after menopause when estrogen levels decline, the glandular tissue withers, with the fatty tissue predominating.

The prostate—on the other hand—is made up of glandular tissue that produces prostate “milk,” and ducts that empty this fluid into the urethra at the time of sexual climax. At ejaculation the prostate fluid combines with other reproductive secretions and sperm to form semen. The remainder of the prostate consists of fibro-muscular tissue. The glandular tissue is sustained by the male sex hormone testosterone and after age 40 there is a slow and gradual increase in the size of the prostate gland because of glandular and fibro-muscular cell growth.

Access to the breasts as mammary feeding zones is via stimulation of the erect nipples through the act of nursing. Access to the prostate fluid is via stimulation of the erect penis, with the release of semen and its prostate fluid component at the time of ejaculation.

Both the breasts and prostate can be considered to be reproductive organs since they are vital to nourishing infants and sperm, respectively. At the same time, they are sexual organs. The breasts can be thought of as accessories with a dual role that not only provide milk to infants, but also function as erogenous zones that attract the interest of the opposite sex and contribute positively to the sexual and thus, reproductive process. Similarly, the prostate is both a reproductive and sexual organ, since sexual stimulation resulting in climax is the means of accessing the prostate’s reproductive function.

Both the breasts and prostate are susceptible to similar disease processes including infection, inflammation and cancer. Congestion of the breast and prostate glands can result in a painful mastitis and prostatitis, respectively. Excluding skin cancer, prostate cancer is the most common cancer in men (accounting for 26% of newly diagnosed cancers with men having a 1 in 7 lifetime risk) and breast cancer is the most common cancer in women (accounting for 29% of newly diagnosed cancers with women having a 1 in 8 lifetime risk). Both breast and prostate tissue are dependent upon the sex hormones estrogen and testosterone, respectively, and one mode of treatment for both breast cancer and prostate cancer is suppression of these hormones with medication, e.g., Tamoxifen and Lupron, respectively. Both breast and prostate cancer incidence increase with aging. The median age of breast cancer at diagnosis is the early 60’s and there are 232,000 new cases per year, 40,000 deaths (the second most common form of cancer death, after lung cancer) and there about 3 million breast cancer survivors in the USA. The median age of prostate cancer at diagnosis is the mid 60’s and there are 221,000 new cases per year, 27,500 deaths (the second most common form of cancer death, after lung cancer) and there are about 2.5 million prostate cancer survivors in the USA.

Both breast and prostate cancer are often detected during a screening examination before symptoms have developed. Breast cancer is often picked up via mammography, whereas prostate cancer is often identified via an elevated or accelerated PSA (Prostate Specific Antigen) blood test. Alternatively, breast and prostate cancer are detected when an abnormal lump is found on breast exam or digital rectal exam of the prostate, respectively.

Both breast and prostate cells may develop a non-invasive form of cancer known as carcinoma in situ—ductal carcinoma-in-situ (DCIS) and high grade prostate intraepithelial neoplasia (HGPIN), respectively—non-invasive forms in which the abnormal cells have not grown beyond the layer of cells where they originated, often predating invasive cancer by years.

Family history is relevant with both breast and prostate cancer since there can be a genetic predisposition to both types and having a first degree relative with the disease will typically increase one’s risk. Imaging tests used in the diagnosis and evaluation of both breast and prostate cancers are similar with both ultrasonography and MRI being very useful. Treatment modalities for both breast and prostate cancer share much in common with important roles for surgery, radiation, chemotherapy and hormone therapy.

In a further twist to the relationship between breast and prostate cancer, a recent study showed that women with close male relatives with prostate cancer are more likely to be diagnosed with breast cancer. Compared to women with no family history of breast or prostate cancer, those with a family history of both were 80% more likely to develop breast cancer.

Breast and Prostate Cancer Myths and Facts

“Only old people get breast or prostate cancer.

Fact: 25% of women with breast cancer develop it before age 50, whereas less than 5% of men with prostate cancer develop it before age 50; however, many men in their 50s are diagnosed with the disease.

“Men can’t get breast cancer and women can’t get prostate cancer.”

Fact: 1700 men are diagnosed with breast cancer with 450 deaths on an annual basis.  Women have structures called the Skene’s glands, which are the female homologue of the male prostate gland. On very rare occasions, the female “prostate” can develop cancer. The Skene’s glands are thought to contribute to “female ejaculation” at the time of sexual climax. 

“All lumps in the breast or prostate are cancer.”

Fact: 80% of breast lumps are due to benign conditions as are 50-80% of prostate “nodules.”  If an abnormality is found, further evaluation is necessary.  

“It’s not worth getting screened for breast cancer because of the USPSTF (United States Preventive Services Task Force) recommendation against routine screening mammography in women aged 40 to 49 years and against clinicians teaching women how to perform breast self-examination.  It’s not worth getting screened for prostate cancer because the USPSTF also recommended against prostate-specific antigen (PSA)-based screening for prostate cancer.”

Fact: In my opinion, the USPSTF has done a great deal of harm to public health in the USA with their recommendations. The goal of screening is to pick up cancers in their earliest stages at times when treatment is likely to be most effective. Not all cancers need to be treated and the treatment can differ quite a bit based upon specifics, but screening populations at risk is a no-brainer.  For breast cancer and prostate cancer–the most common cancer in each gender–it is important to screen aggressively to obtain the necessary information to enable doctors and their patients make sensible decisions, which are individualized and nuanced, depending on a number of factors.

Wishing you the best of health,

Fat: Location, Location, Location Matters

September 14, 2012

Andrew Siegel, M.D.     Blog #74

 

We all have body fat; even elite athletes have a body composition that is a svelte 5-10% fat—this translates into roughly 10-20 pounds of fat for a 180-pound athlete.  What is important is that all fat is not created equal—where the fat accumulates in our bodies dramatically effects how that fat behaves.  So, the very location where your fat takes up residence has a tremendous influence on your health.

Fat on our body surface is much less problematic than fat deep within our body. Humans have two basic types of fat: subcutaneous fat and visceral fat. Subcutaneous fat—also known as “love handles,” “spare tires,” “muffin tops,” or “middle-age spread”—is present between the skin and the abdominal wall. When present in normal amounts, it gives us nice contours and makes us look less bony and skeletal and more smooth and curvy. When present in excessive amounts, it makes us look plump, roly-poly and pear-shaped. A moderate amount of subcutaneous fat is of little danger to our health and, in fact, provides us numerous advantages including padding and insulation to conserve heat and help with temperature regulation, a means of storage of fat-soluble vitamins, and a ready source of energy. Visceral fat—also referred to as a “pot belly,” “beer belly,” or “Buddha belly”—is internal fat deep within the abdominal cavity that can make us apple-shaped.  It wraps around our internal organs including our liver, kidneys, and pancreas. Visceral fat is always unhealthy fat that can have dire metabolic consequences. In general, waist circumference is a reasonably good measure of visceral fat. (Of course, morbid obesity due to either type of fat can prove extremely  dangerous to one’s health.)

It’s kind of like real estate, the value of which is predicated on location, location, location. Think of visceral fat as prime, expensive beachfront property on the gold coast with a short walk to the ocean, the ocean of metabolic disasters.  Think of subcutaneous fat as less expensive, inland property, quite removed from this ocean of metabolic disasters.  Clearly, visceral fat is fat that behaves badly and fat that is strongly desirable to avoid.

In many ways, the distinction between subcutaneous and visceral fat parallels the distinction between good fats and bad fats in our diet.    The not unhealthy one or two inches of subcutaneous fat that you can pinch around your waistline can be thought of as a good fat such as the fat in olive oil, avocados, or nuts.   On the other hand, the unhealthy visceral fat that causes a man to have a big protuberant abdomen—creating an appearance not unlike a very pregnant female—can be thought of as bad fats such as the partially hydrogenated fats present in vegetable shortening that are commonly used in fast foods and other processed baked goods.

Visceral fat storage is not static but dynamic, meaning that there is continuous mobilization of our fat (as fatty acids) and storage (as triglycerides).  Lipolysis is the chemical reaction in which the fat is broken down into fatty acids that the body can use as energy. This can occur very readily in visceral fat. Likewise, accumulation of visceral fat can occur in a very rapid fashion. Excessive intake of calories will be rapidly stored as visceral fat, whereas under circumstances of a reduced calorie intake, the visceral fat is broken down to provide fuel for our bodies’ metabolic processes, particularly muscle contraction.

Visceral fat is not just a bland collection of fatty tissue sitting inertly within your belly causing an oversized appearance to your abdomen.  It is an extremely metabolically active endocrine organ with a life of its own.  Fat is the largest endocrine organ in our bodies and it releases a myriad of pro-inflammatory factors, hormones and immune cells that can affect metabolism and other bodily functions. Fat has an abundance of the hormone aromatase, which converts testosterone to the female hormone estrogen.  One consequence of too much fat in men is excessive conversion of testosterone to estrogen. Men with plentiful visceral fat often will bear the consequences of lower testosterone and higher estrogen levels, including sexual issues and breast development as well as numerous other negative consequences of insufficient levels of testosterone.

Visceral fat is intimately connected to the inflammatory process and can result in insulin resistance, metabolic syndrome, cardiovascular disease and an entire array of negative health ramifications, including chronic diseases such as arthritis and cancer.  This is in contradistinction to subcutaneous fat, which produces far less inflammatory chemicals. Since men have a tendency towards visceral fat collection whereas women have a tendency towards subcutaneous fat collection, this might explain why women are less susceptible to cardiovascular disease then men are.

Insulin is the principal regulator of fat metabolism. After a sugar and carbohydrate load, insulin is released to get the fuel into our cells. When we go without food, as happens when we sleep, insulin levels decrease and fat is released to be used as fuel.  Insulin levels are determined primarily in response to our carbohydrate intake in order to keep our blood sugar regulated. Insulin has much to do with the way our bodies store or burn fat. You can think of insulin as our fat hormone—when insulin levels are elevated, we accumulate fat; when levels are low, we burn fat for fuel.  So if you have a substantial collection of visceral fat, it becomes highly desirable to reduce sugar and refined carbohydrate intake to decrease insulin and burn away that bad, pro-inflammatory fat as fuel. The good news is that by losing abdominal fat, the potentially bad health repercussions can be reversed. The dangerous visceral fat submits relatively easily to diet and exercise whereas the less harmful subcutaneous fat at the waist is more stubborn and resistant to reversal measures.

How To Burn Fat:

  • Eat in accordance with nature’s design—meaning whole foods.  Avoid processed foods.  The best diet is an “anti-processed-atarian” diet.
  • Avoid “naked” calories (stripped of fiber), so restrict sugar, simple white carbohydrates, and liquid calories. Specifically avoidsugared drinks, white pasta, white rice, white bread, doughnuts, bagels, potatoes, etc.  Aggressively steer clear of high fructose corn syrup.
  •  Eat high-quality, whole-grain, high-fiber carbohydrates (whole grain pasta, brown rice, whole grain breads, legumes, whole fruits and vegetables), lean protein sources (easy on meat and dairy) and healthy fats (vegetable and seafood-origin).
  • Avoid giant meals in which the caloric load will be stored as fat; substitute with multiple smaller meals in which the calories will be used for immediate energy.
  • Limit after dinner snacking since unnecessary calories at a time of minimal physical activity will be stored as fat.
  • You must incorporate exercise into your lifestyle, achieving balance between aerobic, resistance and core workouts.  Aerobic exercise has great potential in burning fat for fuel and interval training seems to really rev up our fat-burning capabilities.
  • Portion control is the name of the game: in order to burn fat, energy intake must be less than energy output.  Even if you eat only the healthiest of foods, if calories in exceed calories out, you will not burn fat for fuel.
  • Minimize stress; if you can’t eliminate it, work to manage it.
  • Get adequate amounts of quality sleep.  See my previous blog entitled “Sleep To Slim” to find details: https://healthdoc13.wordpress.com/2012/07/20/sleep-to-slim/

The bottom line is that while body fat in any excessive amount is unhealthy and unattractive, it becomes a potentially life-threatening issue depending on its location in our bodies.  An enormously protuberant belly can lead to processes that result in disease—and even death.
