HRT and cancer
Excessive thickening of the lining of the womb
(endometrial hyperplasia) and cancer of the lining of the
womb (endometrial cancer)
Using oestrogen-only HRT will increase the risk of excessive
thickening of the lining of the womb (endometrial hyperplasia)
and cancer of the womb lining (endometrial cancer).
1. WHAT OESTROGEL IS AND WHAT IT IS USED FOR
Oestrogel is a Hormone Replacement Therapy (HRT). It
contains the female hormone oestrogen.
Oestrogel is used in postmenopausal women with at least 6
months since their last natural period.
Using a progestogen in addition to the oestrogen for at least 12
days of each 28 day cycle protects you from this extra risk. So
your doctor will prescribe a progestogen separately if you still
have your womb. If you have had your womb removed (a
hysterectomy), discuss with your doctor whether you can
safely take this product without a progestogen.
Oestrogel is used for:
Relief of symptoms occurring after menopause
During the menopause, the amount of the oestrogen produced
by a woman’s body drops.
This can cause symptoms such as hot face, neck and chest
(“hot flushes”). Oestrogel alleviates these symptoms after
menopause. You will only be prescribed Oestrogel if your
symptoms seriously hinder your daily life.
In women who still have a womb and who are not using HRT,
on average, 5 in 1000 will be diagnosed with endometrial
cancer between the ages of 50 and 65.
For women aged 50 to 65 who still have a womb and who take
oestrogen-only HRT, between 10 and 60 women in 1000 will be
diagnosed with endometrial cancer (i.e. between 5 and 55
extra cases), depending on the dose and for how long it is
Prevention of osteoporosis
After the menopause some women may develop fragile bones
(osteoporosis). You should discuss all available options with
If you are at an increased risk of fractures due to osteoporosis
and other medicines are not suitable for you, you can use
Oestrogel to prevent osteoporosis after menopause.
How Oestrogel works
Oestrogel works by replacing the oestrogen in your body. This
is so that you have a similar amount of oestrogen as before
2. WHAT YOU NEED TO KNOW BEFORE YOU USE
Medical history and regular check-ups
The use of HRT carries risks which need to be considered
when deciding whether to start using it, or whether to carry on
The experience in treating women with a premature menopause (due to ovarian failure or surgery) is limited. If you have
a premature menopause the risks of using HRT may be
different. Please talk to your doctor.
Before you start (or restart) HRT your doctor will ask you about
your own and your family’s medical history. Your doctor may
decide to perform a physical examination. This may include an
examination of your breasts and/or an internal examination, if
Once you have started on Oestrogel you should see your
doctor for regular check-ups (at least once a year). At these
check-ups, discuss with your doctor the benefits and risks of
continuing with Oestrogel.
Go for regular breast screening, as recommended by your
Do not use Oestrogel
If any of the following applies to you. If you are not sure about
any of the points below, talk to your doctor before using
Do not use Oestrogel:
• If you have or have ever had breast cancer, or if
you are suspected of having it,
• If you have cancer which is sensitive to oestrogen, such
as cancer of the womb lining (endometrium), or if you
are suspected of having it,
• If you have any unexplained vaginal bleeding,
• If you have excessive thickening of the womb lining
(endometrial hyperplasia) that is not being treated,
• If you have or have ever had blood clots in a vein
(thrombosis), such as in the legs (deep venous
thrombosis) or lungs (pulmonary embolism),
• If you have a blood clotting disorder (such as protein C,
protein S, or antithrombin deficiency),
• If you have or recently have had a disease caused by
blood clots in the arteries, such as a heart attack, stroke
• If you have or have ever had a liver disease and your
liver function tests have not returned to normal,
• If you have a rare blood problem called “porphyria”
which is passed down in families (inherited),
• If you are allergic to estradiol or any other ingredients of
this medicine (listed in section 6).
If any of the above conditions appear for the first time while
using Oestrogel, stop using it at once and consult your doctor
Warnings and precautions
Tell your doctor if you have ever had any of the following
problems, before you start the treatment, as these may return
or become worse during treatment with Oestrogel. If so, you
should see your doctor more often for check-ups:
• fibrosis inside your womb,
• growth of womb lining outside your womb
(endometriosis) or a history of excessive growth of the
womb lining (endometrial hyperplasia),
• increased risk of developing blood clots (see
“Blood clots in a vein (thrombosis)”),
• increased risk of getting an oestrogen-sensitive cancer
(such as having a mother, sister or grandmother who
has had breast cancer),
• high blood pressure,
• a liver disorder, such as a benign liver tumor,
• migraine or severe headaches,
• a disease of the immune system that affects many
organs of the body (Systemic Lupus Erythematosus,
• a disease affecting the eardrum and hearing
• a very high level of fat in your blood (triglycerides),
• fluid retention due to heart or kidney problems.
You may have irregular bleeding or drops of blood (spotting)
during the first 3-6 months of using Oestrogel. However, if the
• carries on for more than the first 6 months
• starts after you have been using Oestrogel for more than
• carries on after you have stopped using Oestrogel see
your doctor as soon as possible.
Evidence suggests that using combined oestrogenprogestogen and possibly also oestrogen-only HRT increases
the risk of breast cancer. The extra risk depends on how long
you take HRT. The additional risk becomes clear within a few
years. However, it returns to normal within a few years
(at most 5) after stopping treatment.
For women who have had their womb removed and who are
using oestrogen-only HRT for 5 years, little or no increase in
breast cancer risk is shown.
Women aged 50 to 79 who are not taking HRT, on average, 9
to 17 in 1000 will be diagnosed with breast cancer over a
5-year period. For women aged 50 to 79 who are taking
oestrogen-progestogen HRT over 5 years, there will be 13 to
23 cases in 1000 users (i.e. an extra 4 to 6 cases).
• Regularly check your breasts. See your doctor if
you notice any changes such as:
- dimpling of the skin
- changes in the nipple
- any lumps you can see or feel.
Additionally, you are advised to join mammography screening
programs when offered to you. For mammogram screening, it
is important that you inform the nurse/healthcare professional
who is actually taking the x-ray that you use HRT, as this
medication may increase the density of your breasts which
may affect the outcome of the mammogram. Where the density
of the breast is increased, mammography may not detect all
Ovarian cancer is rare, much rarer than breast cancer. The use
of oestrogen-only or combined oestrogen-progestogen HRT
has been associated with a slightly increased risk of ovarian
cancer. The risk of ovarian cancer varies with age.
For example, in women aged 50 to 54 who are not taking HRT,
about 2 women in 2000 will be diagnosed with ovarian cancer
over a 5-year period. For women who have been using HRT for
5 years, there will be about 3 cases per 2000 users (i.e. about
1 extra case).
Effect of HRT on heart and circulation
Blood clots in a vein (thrombosis)
The risk of blood clots in the veins is about 1.3 to 3- times
higher in HRT users than in non-users, especially during the
first year of using it.
Blood clots can be serious, and if one travels to the lungs, it can
cause chest pain, breathlessness, fainting or even death.
You are more likely to get a blood clot in your veins as you get
older and if any of the following applies to you. Inform your
doctor if any of these situations applies to you:
• you are unable to walk for a long time because of major
surgery, injury or illness (see also section 3, If you need
to have surgery)
• you are seriously overweight (BMI >30 kg/m2)
• you have any blood clotting problem that needs
long-term treatment with a medicine used to prevent
• if any of your close relatives has ever had a blood clot in
the leg, lung or another organ
• you have systemic lupus erythematosus (SLE)
• you have cancer.
For signs of a blood clot, see “Stop using Oestrogel and see a
Looking at women in their 50s who are not using HRT, on
average, over a 5-year period, 4 to 7 in 1000 would be
expected to get a blood clot in a vein.
For women in their 50s who have been using oestrogenprogestogen HRT for over 5 years, there will be 9 to 12 cases
in 1000 users (i.e.an extra 5 cases).
For women in their 50s who have had their womb removed and
have been using oestrogen-only HRT for over 5 years, there
will be 5 to 8 cases in 1000 users (i.e. 1 extra case).
Heart disease (heart attack)
There is no evidence that HRT will prevent a heart attack.
Women over the age of 60 years who use oestrogenprogestogen HRT are slightly more likely to develop heart
disease than those not using any HRT.
For women who have had their womb removed and are using
oestrogen-only therapy there is no increased risk of developing
a heart disease.
The risk of getting stroke is about 1.5 times higher in HRT users
than in non-users. The number of extra cases of stroke due to
use of HRT will increase with age.
Looking at women in their 50s who are not using HRT, on
average, 8 in 1000 would be expected to have a stroke over a
5-year period. For women in their 50s who are using HRT, there
will be 11 cases in 1000 users, over 5 years (i.e. an extra 3
HRT will not prevent memory loss. There is some evidence of
a higher risk of memory loss in women who start using HRT
after the age of 65. Speak to your doctor for advice.
