  Instagram Profile - Karene (Sexual Evolution)


Introduction / Summary (2018): Hello and welcome to our Sexuality pages. While this is not a pornographic site, it is provocative - founded upon what people search on the Internet (which is very interesting!). We then relate this to our biological and cultural evolution.
Sex is obviously important to people - and if you want to improve your sexual relationships then knowing the truth about our human evolution is the best foundation. By opening our minds to a greater diversity of behaviors, this knowledge will help you creatively cultivate healthy pleasurable moral attitudes and sexy smutty relationships (free from religious guilt & cultural myths).
Support an open honest discussion on the truth of our sexual evolution and behaviour. If you support sex positive, moral, informed sexual behaviour please share this knowledge. (These pages have a diverse collection of fascinating information relating to our human sexual evolution so people will appreciate it - see our 'nice letters' page!).
Sincerely, Karene.

Awareness of Types (IBC / Inflammatory, Lump). Causes, Symptoms, Statistics, Mainstream Vs Alternative Treatment

There is an emerging view about human health that many of our problems have two central causes.

i) We live very removed from how we evolved to live. e.g. Living in Nature, consuming natural food rather than agricultural mass produced food (using chemicals), exercising each day as we struggled to survive.

2. We are now exposed to tens of thousands of 'man made' chemicals, of which only several hundred have been studied in any great detail in terms of their effects on human health.

So the first step in any disease treatment must be to learn from Nature and try and eliminate toxins from entering the body (clean food, air and water), and to ensure that you get daily physical exercise outside (some exposure to sun each day is important).
We are planning a substantial evolutionary health section on this website which will cover this in more detail, and also look at holistic health and homeopathy treatments for cancer.

In relation to breast cancer there seems to be a causal connection between the number of times a woman has menstrual cycles and the incidence of breast cancer. Given that our ancestors did not have birth control, thus the female was either pregnant or breast feeding and infertile, thus our ancestors did not have many menstrual cycles.
How can this help women in our modern world?
Well it suggests two obvious things.

i) We need to find better hormone strategies for women's birth control pills that mimic more closely the natural cycle of a women of being pregnant and then breast feeding (to minimise number and severity of menstrual cycles). Whether this is possible or not is unknown, but it should certainly be explored.

ii) Women should be encouraged to breast feed for as long as possible (probably up to three years is natural).

For now please enjoy the following articles (which we are working on at the moment).

Breast Cancer Risk and Number of Menstrual Cycles

From the website: 'This study explores whether the lifetime cumulative number of menstrual cycles, as an index for total exposure to endogenous estrogens, and the number of menstrual cycles until a first full-term pregnancy (FFTP), are associated with breast cancer risk in postmenopausal women.

We observed an increased breast cancer risk in women with a higher number of cumulative menstrual cycles in their lifetime.'

This study found similar results: A highly significant linear relationship between breast cancer risk and both the cumulative number of cycles before a first FTP (full term pregnancy) and lifetime.

Hormones in Menstrual Cycles may affect Cancer Risk

Several reproductive factors have been linked to increased risk of breast cancer - from early menses and late menopause to childlessness and late age at first pregnancy. A new study would add yet another: menstrual cycles that are typically either shorter or longer than average.

Although epidemiogical studies have linked lifetime estrogen exposures to breast cancer - with higher exposures increasing risk - Whelan and many others suspect that hormones in general (including estrogen and progesterone), and their peaks during an ovulation cycle, collectively affect cancer risk.

In the Dec. 15, 1994 American Journal of Epidemiology, Whelan reports that compared to women with menstrual cycles lasting 26 to 29 days during the most stable period of their reproductive lives (age 25 to 29), those with shorter cycles face roughly twice the risk of breast cancer. Her team also found a near doubling of breast cancer risk in women whose cycles exceeded the average length.

Whelan concludes that women with extremes in cycle length probably possess “some hormonal disturbance that not only gives them a wacky cycle . . . but also increases their risk of breast cancer."

Breast Cancer, Menstruation, Diet & Exercise

From the website: 'Breast cancer is the most commonly diagnosed cancer in women. While the exact cause (or causes) of breast cancer remains unknown, certain features or aspects of a woman’s life appear to increase the chance that she may develop breast cancer during her lifetime. A woman who has her first menstrual period at an early age is more likely to be diagnosed with breast cancer than a woman who has her first menstrual period at a later age. Women who produce an egg during each menstrual cycle are also more likely to be diagnosed with breast cancer compared to women who do not produce an egg at each menstrual cycle.

The primary purpose of this study is to examine certain behaviors, specifically what a woman eats and her amount of physical activity, and how these behaviors relate to when she had her first menstrual period and whether she produced an egg during her menstrual cycles after she began having periods.'

Timing of Breast Cancer Surgery & Menstrual Cycle

From the website: 'Surgery is the most common treatment for early breast cancer. There may be a particular time during the menstrual cycle when breast cancer surgery is less successful and results in decreased survival.

The research team found that women who were operated on in the follicular phase (i.e., occurring between menstruation and ovulation) had a worse outcome (i.e., recurrence or death) than women in their luteal phase (after ovulation), while adjusting for stage of breast cancer, type of surgery, family history, and age.

This research (i.e., timing breast cancer surgery around the woman's menstrual cycle), could be implemented into the clinical arena as a simple, but powerful therapeutic tool, that could potentially extend and/ or save a substantial number of women's lives.'

Breast Cancer Rates Drop in United States: Reduction in Hormone Replacement Therapy (HRT)

The incidence of breast cancer in the United States dropped precipitously in 2003, and new research suggests the downward trend was the result of millions of women discontinuing use of hormone replacement therapy.
