Menopause after cancer treatment

Some cancer treatments can cause side effects similar to menopause symptoms. 

If you are a younger person having periods, you may experience an early menopause.

It can feel challenging to face the symptoms and implications of the menopause on top of those caused by your cancer, diagnosis and treatment.

This page has information about menopause and cancer, ways to manage and reduce the symptoms you might experience, and how Maggie’s can help.

About menopause and cancer

Menopause is a natural part of the aging process caused by a change in hormone levels. 

Your ovaries gradually produce less oestrogen and progesterone, your periods stop, and pregnancy becomes no longer possible.

It usually happens to people between the ages of 45 and 55, and it can happen to some transgender men and non-binary and intersex people too.

Some cancer treatments can affect your hormones and trigger menopause symptoms or an early menopause.

In women, these treatments include:

• chemotherapy
• surgery to remove both ovaries
• radiotherapy to the pelvis
• drugs that block or lower the production of certain hormones in the body (hormone therapy)

Early menopause

Early menopause is when your periods stop before the age of 45.

In some people, menopause caused by cancer treatment will be temporary, but for others it will be permanent. This depends on:

• the type of treatment you’re having
• how near you are to your natural menopause age

Even if you have already been through the menopause naturally, you may experience menopause symptoms again during cancer treatment. 

This is especially the case with some hormone therapies for breast cancer or having surgery to remove your ovaries.

Menopause symptoms

The change in hormone levels during the menopause can cause various symptoms. 

They are often experienced more intensely when menopause is caused by cancer treatment, because your hormone supply stops suddenly.

Symptoms of the menopause include:

• anxiety
• ‘brain fog’, cognitive change and problems with memory and concentration
• difficulty sleeping
• feelings of loss of identity and self confidence
• hair changes, including hair loss, thinning and an increase in facial hair
• headaches and migraines
• hot flushes
• irritable bladder
• joint stiffness, aches and pains
• mood changes, including low mood and emotional dysregulation
• night sweats
• palpitations
• recurrent cystitis and urinary tract infections (UTIs)
• reduced sex drive (libido)
• skin changes
• vaginal dryness and discomfort
• weight changes

Menopause symptoms can affect different areas of your daily life, including your relationships, social life, work, and physical and mental wellbeing.

This can feel like a lot to deal with when you are facing the other challenges of a cancer diagnosis.

Our cancer support specialists are here for you, and we run menopause workshops across our centres. Visit your nearest Maggie’s centre to find out more.

Men, cancer and menopause

Hormone therapy for prostate cancer or male breast cancer reduces or blocks the production of testosterone. 

This can cause many of the symptoms associated with the menopause, as well as erectile dysfunction and breast enlargement (gynaecomastia).

This is sometimes called the male menopause, or the andropause. It can affect some transgender women and non-binary and intersex people too.

Menopause treatments

There are several interventions that can help you manage your menopause symptoms and your long-term health. 

Some interventions may interfere with your cancer treatment, so it is important to speak with your doctor to discuss them.

Non-medical menopause interventions

• Cognitive Behaviour Therapy (CBT) workshops
• Acupuncture
• Clinical hypnotherapy
• Herbal products and supplements

Some herbal products for relieving menopause symptoms are not recommended for people with cancer. Black cohosh and St John's wort, for example, can interact with certain cancer drugs.

Cancer support specialists at your local Maggie’s centre will be able to offer you more information about intervention options before you speak with your doctor.

Medical menopause interventions

If you are below 60 years of age and your cancer is not oestrogen sensitive, you may be able to take Hormone Replacement Therapy (HRT). 

HRT replaces oestrogen and progesterone, which fall to low levels during the menopause.

There are many different types of HRT, and there are also non-hormonal medications that you may be able to take to ease symptoms. 

Your healthcare team can prescribe the medication that is right for you.

Menopause implications

The change in hormone levels during the menopause can negatively affect:

• your long-term bone
• your long-term heart health
• your risk of developing dementia

If you are experiencing a medically induced menopause, your hormone levels will fall earlier than normal, so it is important for you to take measures to reduce these risks.

• Taking Vitamin D supplements (800-1000 IU or 20–25 mcg a day) and increasing your calcium intake to 1000–1200mg a day will help maintain your bone health.
• HRT can help to mitigate the implications of early menopause on long-term health. 

NICE recommend HRT for anyone under the age of 50 experiencing a medically induced menopause who has a non-oestrogen sensitive cancer. Your healthcare team will be able to advise whether HRT is an option for you.

Lifestyle changes

There are also some positive lifestyle changes you can make to help you cope with a medically induced menopause and its symptoms.

• Eat a healthy, balanced diet, including calcium-rich foods
• Regular, gentle exercise, including activities where you are on your feet, such as walking
• Get lots of rest and sleep
• Maintain a healthy weight
• Reduce intake of salt, alcohol and caffeine
• Stop smoking
• Do relaxing things to manage your stress and anxiety, such as massages and acupuncture
• Understand your triggers and plan ahead

Maggie’s runs a range of workshops on nutrition, sleep, menopause and managing stress, as well as activities like yoga, tai chi, meditation and gentle exercise.

Fertility concerns

You may have concerns about the impact of your cancer treatment on your fertility, whether you were planning a family soon or not. 

It is important to raise your concerns to your healthcare team early on before treatment starts. They can discuss any possible measures to preserve your fertility.

The emotional impact of loss of fertility or uncertainty around fertility can be very difficult, and it is understandable that you may need extra support. 

Find out more about fertility and cancer or speak to a Cancer Support Specialist at your local Maggie’s centre.

Managing the menopause and cancer

An early menopause or menopause symptoms can seem like another big step in a life already affected by cancer. 

You may have lots of questions for your healthcare team about menopause treatments and managing your symptoms, or you may be feeling overwhelmed and unsure what to ask.

Here are some points to consider when discussing your early menopause or menopause symptoms with your healthcare team.

• Find out about the cancer treatment you’re having, and whether this will cause an early menopause or menopause symptoms.
• Ask whether the menopause will be temporary or permanent, and the possible impact on your fertility.
• If you are experiencing early menopause, ask your healthcare team how they will monitor your bone and heart health in the years post menopause.
• If you are receiving cancer treatment and you are finding the symptoms of the menopause severe, tell your healthcare team. There are different ways the symptoms can be managed and medications that can be prescribed to help.
• If you were going through the menopause naturally before your cancer diagnosis and have had to stop HRT, you may have experienced a surge of menopause symptoms. Ask your doctor about the best ways to manage this.
• A common symptom of menopause is vaginal dryness, which can be uncomfortable, cause bladder infections and impact your sex life. Ask your GP or specialist nurse about creams and lubricants that can help ease the symptoms.

For more guidance, visit your local Maggie’s centre. Our Cancer Support Specialists are here to listen and support you, offering advice and information that is right for you.

When to seek further help

Many cancer symptoms interlink with the menopause. 

At times, it can be hard understand whether you are experiencing menopausal symptoms, treatment symptoms or side effects of medication.

• If you notice any new symptoms, or are concerned in any way, let your healthcare team know.
• If you notice vaginal spotting or bleeding after your periods have stopped, inform your healthcare team. Some treatments may cause this problem.
• A medically induced menopause or menopause symptoms may be intense, and it can feel a lot to deal with on top of your cancer treatment. Tell your doctor if it feels like you are struggling to cope, and they will be able to help you.
• The menopause can add to feelings of low self-esteem, anxiety and depression. If these symptoms are affecting you, let your healthcare team know. It might feel hard to reach out for support, but it can be a positive step to reducing the impact. Opening up to family and friends and finding support at a Maggie’s centre may also help.
