Hi all, today's blog post will follow on from yesterdays and focus on the news that
Angelina Jolie has had a preventative double mastectomy after discovering she
has the BRCA1 gene mutation, giving her an 87% chance of developing breast
cancer. The BRCA gene mutations also give you an increased risk of ovarian
cancer and I have read today that Angelina is also going to have her ovaries
removed to prevent her being diagnosed with this cancer type too. I hope you
find this post informative.

What is an Oophorectomy?
An oophorectomy is the surgical removal of your ovaries. Your ovaries
are almond shaped organs which sit on either side of the uterus. They contain
eggs and secrete hormones that control your reproductive cycle. Removal of your
ovaries will reduce the amount of oestrogen and progesterone in your body and
this can halt cancers that require these hormones to grow.
Ladies with the BRCA mutation may also have their fallopian tubes
removed and this is known as a salpingo-oophorectomy.
Who Can Have a Preventative Oophorectomy?
This surgery is normally reserved for women with an increased risk of
developing ovarian cancer, usually due to a BRCA1 or BRCA2 gene mutation. Women
aged over thirty five that have already had their children and are found to be
at high risk of developing ovarian cancer are usually offered this surgery but other
woman also qualify, including those with a strong family history of ovarian
cancer but do not carry the gene mutation.
How does it Reduce your Cancer Risk?
A preventative oophorectomy can decrease your risk of breast and ovarian
cancer if you have a BRCA mutation:
*Your breast cancer risk is reduced by about 50% if you are pre
menopausal. For example a woman with a 60% chance of being diagnosed with
breast cancer would see her chances decrease to 30% with an oophorectomy.
*Your ovarian cancer risk would decrease by 80-90%. For example a woman
with a 30% chance of developing ovarian cancer would see her chances decrease
to 6%.
These figures do depend on individuals though as your risk can depend on
many factors including lifestyle and family history. Some women may find that
an oophorectomy reduces their risk significantly whilst others may find the
surgery risks and side effects may not be worth the reduced risk of cancer.
Risks Involved:
An oophorectomy is a safe procedure with minimal complications, although
the risks depend on how the procedure is performed. Potential risks could
include damage to internal organs and intestinal blockage.
Oophorectomy causes early menopause in women that have not yet reached
the menopause and this can cause:
*Osteoporosis – the amount of
oestrogen being produced is reduced and this may increase your chance of
breaking bones as they become thinner.
*Increased Risk of Heart Disease
– Your risk of developing high cholesterol and heart disease may increase if
you have your ovaries removed.
*Menopausal Side Effects –
Hot flushes, vaginal dryness, sexual problems and sleep disturbance are all
common side effects of menopause.
*You May Still Be At Risk –
This surgery does not completely eradicate your risk of developing breast
and/or ovarian cancer as a type of cancer that mimics ovarian cancer (primary
peritoneal cancer) can develop. However the risk of developing this cancer type
is low, much much lower then the risk of ovarian cancer if you keep your ovaries.
*Fertility – Removing your
ovaries will obviously affect your fertility so if you have not started or
completed your family yet it may be worth looking into options including
egg/embryo freezing before going ahead with the surgery.
I hope you have found this post informative, please do visit your GP if

Sending lots of love to anyone known to carry a gene mutation and anyone
that has undergone this procedure to try and prevent themselves being diagnosed
with cancer.
