A large number of cancers are categorised as being hormonally responsive, and the hormone responsible in many of these cases is estrogen. Commonly known as the female sex hormone, estrogen is a major driver of many cancers for both men and women. Breast cancer, endometrial, cervical, ovarian, colon, brain tumours and testicular and prostate cancer are just some examples. Estrogen has been found to be the culprit behind even some lung cancers.

Estrogen is actually not a single hormone, but a family of hormones with varying chemical strengths. Some are dangerous, others are less so. Estradiol, an aggressive form of estrogen, is one troublemaker. Research shows that some prostate cancers are driven by a chemical called DHT – produced when estradiol attacks the male hormone, testosterone.

Two in three breast cancers are driven by estrogen, specifically estradiol. This troublesome hormone can cause healthy cells to mutate and stem cells to stay in their rapidly dividing state. It can lower oxygen levels in the cell by 40 per cent, cause malfunctioning of the transport systems across the cell membrane, poison the cell and even help the spread of the cancer message. Trouble starts when dangerous forms of estrogen bind to cell receptor sites, feeding the cancer.

When you have an estrogen-receptor positive (ER+) cancer, you need to avoid adding to the estrogen pool in your body. However, we are constantly exposed to chemicals in our environment, personal care products, household products and our foods which act like estrogen in the body. Examples of some external estrogen-like chemicals are pesticides, BPA, phthalates, toluene, perfumes, and parabens. These exogenous estrogens are called xenoestrogens. Some can be just as harmful as the more aggressive natural estrogens like estradiol.

Xenoestrogens are not the same as phytoestrogens, which are natural estrogens or estrogen-mimics derived from plants. Typically, xenoestrogens are far more potent and dangerous. They can wreak havoc on our endocrine system, creating a host of health problems.

What are some sources of xenoestrogens? Here are some bad guys to watch out for:

Nail varnishes and cleaners – these may contain xylene, formaldehyde and toluene, ingredients associated with health risks like damage to DNA and the liver, skin and respiratory irritation, and neurotoxins. Toulene, an estrogen-mimic, also affects the endocrine system.

Perfume and products with synthetic fragrances – these can be a mixture of over 100 different ingredients, and they are not all required to be named on the label. You need to be vigilant, as several are potent endocrine system disrupters and estrogen mimics. Toluene, for instance, is used in the manufacture of many perfumes.

Swedish research shows that 75 per cent of ordinary, everyday perfumed products used on the body produced DEHP – a very powerful estrogen mimic – once in the blood stream. The researchers discovered that that three-quarters of toiletry products tested contained DEHP and phthalates. Synthetic fragrances, perfumed body sprays, hairsprays and hair products were the main culprits. US research with pregnant women found that DEHP was so powerful that 11 per cent of male offspring born to mothers with high DEHP levels had genital defects. Another study concluded that some testicular cancers can start in the womb because of the use of synthetic fragrances or other xenoestrogens on the skin during pregnancy.

Men should not be complacent as DEHP is also found in soaps, shaving foam and aftershave. Practically all these products contain synthetic perfumes.

Cleaning agents, textiles, plastics, cosmetics and some kinds of paper – these are typical sources of a chemical called 4-nonylphenol (4-NP), an endocrine disrupter as well as an estrogen-mimic. 4-nonylphenol has proven to be a breast cancer threat , as reported by the Journal of Applied Toxicology in 2005. It has also been reported to affect semen quality.

Plastics and plastic additives – bisphenol A (BPA) is an ingredient previously used as a fungicide which is now used to manufacture many plastics and plastic additives. It is an endocrine disrupter, mimicking hormones like estrogen. Epoxy resins containing bisphenol A are used as coatings on the inside of almost all food and beverage cans, including bottle caps. Even water supply lines are coated with this chemical.

Bisphenol A is a key component in the manufacture of polycarbonate plastic, a clear and nearly shatter-proof plastic used to make a variety of common products including baby and water bottles, sports equipment, medical and dental devices, dental fillings and sealants, eyeglass lenses, CDs and DVDs, and household electronics. Bisphenol A is a popular color developer in thermal paper and in carbonless copy paper.

Flexible plastics, toys, toiletries and other personal care or beauty products – these widely contain phthalates, another endocrine disrupter and estrogen-mimic. Like other endocrine disrupters, phthalates can elevate estradiol production and cause chromosomal damage. Phthalates leach from certain plasticisers used in plastic bottles, used to contain anything from drinking water to hair shampoo and other personal care products.

Cosmetics like face creams, lipsticks etc – many contain estrogen mimics. Dr Ana Soto of Tuft’s experimented with 10 such estrogen mimics, all normal product ingredients designated as safe levels by the US Government. In studies with rats she got a full estrogen response, the sort of effect you might see from the most potent form of estrogen, estradiol. That was just 10 ingredients! How many more estrogen mimics are you exposed to each week in your own home? Probably hundreds.

Finally (for this post any way) sodium lauryl sulphate in soaps, bubble bath, shampoos, dishwashing detergent and so on can increase the permeability of the skin by up to 40 per cent. This just allows more hormone mimics to pass into the blood stream. If you’re still using personal care and household products with sodium lauryl sulphate, for goodness sake WAKE UP! There are alternative, safe toiletry, skin care and household products available today. At least one brand, Neways International, avoids using 3,000 questionable ingredients, including the estrogen-mimics mentioned here.

If you haven’t already done so, switch to using personal care and household care products which are free from questionable ingredients, like xenoestrogens. It could save your life.

Seventeen students in a school in Singapore recently came down with pain, vomiting and diarrhoea. Everyone initially thought that the source of their illness was snacks at a class party. To everyone’s surprise, the culprit turned out to be phthalates in a toy that they played with just before eating. As the children did not wash their hands, the chemicals transferred from their hands into their mouths.

Phthalates are chemicals used to make plastics flexible. The specific phthalates found in the toy were dibutyl phthalates (DBP) and diethylhexyl phthalates (DEHP). The US has classified DEHP as a “probable human carcinogen” while the European Chemical Agency calls it a “Substance of Very High Concern”.

Phthalates are widely used. They are in soft PVC products like packaging, flooring, mats, milk bottles, toys, food containers and so on. Soft PVC products contain over 40% of phthalates by weight. The “new car” smell that motorists love comes from phthalates emitting from the dashboards of vehicles that have been in the sun. As the motor vehicle cools downs, the phthalates re-condense as an oily film on the inside of the windscreen. Yet another reason not to buy new cars.

I always avoid heating food up in plastic containers. Plastics with recycling codes 3 and 7, in particular, tend to contain phthalates. I also stay away from personal care products which contain phthalates. Yes, many cosmetics, fragrances, soaps, shampoos, lotions, deodorants and even baby powder contain phthalates. Phthalates are popularly used to enhance fragrances in skin care, hair care and beauty products like perfumes, hair spray, and nail polish. These chemicals are also found in environmental products like wood finishers and lubricants.

Manufacturers are sneaky. Phthalates are rarely listed on the ingredients label. Be smart; look out for proxy ingredients like “fragrance”.

A 2009 survey on phthalate levels in the environment by the US Centre For Disease Control and Prevention (CDC) found that exposure to these chemicals was extremely widespread. Concerned, US authorities warned that DEHP was particularly likely to cause serious development problems in the sexual reproductive systems of young male children. Phthalates act as hormone disrupters. DBP and DEHP, especially, disrupt aromotase, an enzyme crucial to the metabolism of sex hormones. These chemicals cats as anti-androgens, or anti-male hormones.

In 2003, a Boston study discovered that men exposed to phthalates had fewer sperm, which also tended to be weaker and deformed. Statistics shows that male infertility is increasing at an alarming rate in industrialized nations, where exposure to phthalates is high. Two common male birth defects are undescended testes and hypospadias (a penile deformity).

Even more alarmingly, it is women of child-bearing age who have the most exposure to phthalates, very likely because of their heavy usage of personal care products containing harmful ingredients like phthalates. Not only are they in danger of producing male babies with sexual development problems, but they are also at risk of developing cancer. Are you using phthalate-free skin care products?

Safety-conscious company Neways International avoids using at least 3,000 questionable ingredients – including phthalates – in its personal care products, such as skin care, hair care, oral hygiene and beauty products. Instead, it uses safe and gentle ingredients as well as technological processes. What’s in the personal care products you use?

Beauty at any price – is it worth dying for?

When I was growing up, I drank either fizzy drinks or beverages made from cordial with every meal. The kitchen always had crates of aerated water lining one wall. We never drank plain water. At best, we would drink sweet tea heaped with sugar, the way our mom liked it.

My family was well-to-do, so we indulged in anything we liked. The dining table groaned with meat dishes, the larder was well-stocked with snacks, chocolates and other confectionery – you get the picture. As for personal care and household care products, we had all the well-known brands. Nothing but the “best” for us. What ingredients went into those products? Who knew and who cared? We were washed and powdered, and we smelled nice. That’s all that mattered.

From my teens, I bought lots of beauty products. They were a mix of unknown brands as well as famous brands. Skin care, hair products, cosmetics, I had the works. All I cared about was whether they made me look and smell good. In those days, what did anybody know about harmful and even carcinogenic ingredients in personal care products? We believed that well-known brands would only be made of the best ingredients, certainly nothing questionable or damaging to health. We never realised that the personal care and beauty products which we used daily could potentially harm us and make us sick.

We’ve come a long way, baby. Consumers today are better-informed about the dangers of common beauty and personal care ingredients such as:

Sodium Lauryl Sulfate (SLS)
Sodium Laureth Sulfate (SLES)
Propylene Glycol
Ethanol / alcohol
Fluoride
Mineral Oil
Petrolatum
Alpha Hydroxy Acids (AHA)
Retinoic Acid
Avobenzone
Homosalate
Benzophenone
Formaldehyde
PEGs
Parabens
Ceteareth-20
Diethanolamine (DEA)

There are many more toxic chemicals and harmful ingredients we are exposed to at home which can cause illnesses like cancer, respiratory problems, eye problems like cataracts, liver and kidney ailments, Alzheimer’s Disease, and allergic reactions. Many of these harmful ingredients are in products we love to slather on our skin, apply on our eyes, put in our hair and clean our mouths with.

Had I known years ago what I know today, I probably would have avoided using most kinds of commercial skin care, hair and other beauty products, and gone natural as far as possible (safe personal care products were virtually unheard of until recent years). Had my parents known what many people know today, I’m sure they would have made better dietary choices.

Today, half my siblings – including myself – have been afflicted with cancer. One lost the battle. My other siblings grapple with a variety of health problems. My father spent the last 30 years of his life fighting a host of medical conditions. My mother has been in poor health for many years and her memory comes and goes. Sheer coincidence?

Prevention is obviously better than cure. We cannot undo the damage that has already been done, but we can do our best from now on to protect ourselves and our loved ones. This is particularly essential for those who are already dealing with health conditions like cancer. Boycott personal care and household products which use inferior and potentially harmful ingredients. Choose brands which avoid using questionable ingredients. Safety-conscious Neways International avoids using more than 3,000 questionable ingredients, and counting. What about the brands you use? What poison are you putting on your skin today?
