WOMEN'S HEALTH: Conspiracy of silence about breast cancer
by Babette Francis
Women who avoid abortions and who have children before the age of 30 have a
greatly reduced risk of breast cancer, according to scientific studies, says
Babette Francis.
In all the thousands of words which have been written on breast cancer since
Kylie Minogue's diagnosis, little has been said about prevention. Emphasis
has been on early diagnosis; none on risk reduction.
Early diagnosis is very important, of course, because the earlier the cancer
is identified, the greater the chance of cure. However, prevention is even
better than cure, but cancer councils, intimidated by feminists, are
reluctant to advise how reproductive factors affect breast-cancer risk.
Most breast cancer is caused by over-exposure to estrogen, a female hormone
made in the ovaries and fat. Estrogen, an acknowledged carcinogen,
stimulates breast tissue to increase cell divisions, which can result in
cancers due to mutations.
The more estrogen breasts are exposed to, the higher the risk of breast
cancer. During each menstrual cycle, women are exposed to increased estrogen
levels at ovulation. Early age at puberty and late menopause increase breast
cancer risk; late puberty and early menopause decrease risk.
Breast cancer risk is affected by the maturation of lobules which comprise
milk glands. At birth females have primitive type 1 lobules which develop
into type 2 lobules at puberty. Both types 1 and 2 are susceptible to
carcinogens. After 32 weeks of pregnancy, lobules mature into type 3
lobules. Type 4 lobules are formed after childbirth and produce milk. Types
3 and 4 are resistant to carcinogens.
If a woman does not have a full-term pregnancy, she has an increased risk of
breast cancer since she never develops types 3 and 4 lobules. If she has
children later in life (after age 30), she has increased risk because for
most of her menstrual life estrogen has been stimulating types 1 and 2
lobules. If she has children as a teenager, she has decreased risk of breast
cancer as lobules mature early to types 3 and 4.
In an article, "Young, Pregnant and Cancer Free", Time magazine (May 2,
2005) stated:
"Women who give birth before age 20 halve their risk of developing breast
cancer, according to a new study. A hormone produced during pregnancy seems
to provide lifetime protection."
Parents who rush a pregnant teenager to an abortion clinic, should be aware
that they are depriving her of protection against a disease which is the
major killer of women of child-bearing age, and the third most significant
cause of death in post-menopausal women. Unplanned pregnancy won't kill you
or your daughter, but breast cancer might.
A woman who breastfeeds has low estrogen cycles or misses menstrual cycles
altogether. She has decreased breast cancer risk due to less exposure to
estrogen and breast tissue maturation to type 4 lobules. Risk decreases with
longer duration of breastfeeding - the World Health Organization recommends
breastfeeding for 24 months. Mothers who leave babies in day-care deprive
themselves of the risk-reduction that breastfeeding provides.
During a normal pregnancy, estrogen levels rise 2,000 per cent by the end of
the first trimester. Most miscarriages do not increase breast cancer risk
since they are associated with low estrogen levels. A first trimester
miscarriage is quite different from induced abortion of a normal pregnancy.
When pregnancy is terminated before breast cells reach full maturity, a
woman is left with more types 1 and 2 lobules than before her pregnancy
started and therefore is at increased risk. The risk is especially high for
teenagers who have an abortion before their first full-term pregnancy; for
women who have never had a child; and for those with a family history of
breast cancer.
Most women who develop breast cancer have not had abortions, nor do all
women who have abortions develop breast cancer. Nevertheless abortion is a
risk factor and is the most avoidable risk factor. Women cannot change
family history, age at puberty or menopause, but they can avoid abortions.
The incidence of breast cancer jumped 40 per cent in 10 years (1987-1997),
28 years after the de facto legalisation of abortion in Australia. If any
business had such a ghastly result, it would be bankrupt, but health
departments remain unmoved.
The best way to reduce risk of breast cancer is to have babies before age 30
and breastfeed as long as possible. This is "the unacknowledged elephant in
the room" - or babies in the nursery which cancer councils do not talk
about.
