This practical, UK-focused guide explains hormone therapy for menopausal support and for cancer care.
It sets out why clinicians may recommend this treatment, what common options look like, and how follow-up is managed in everyday practice. The page separates menopause HRT and cancer endocrine approaches so readers see why the meaning changes with context.
The article takes a balanced, benefit–risk view. It shows how clinicians weigh symptom relief or cancer control against likely side effects and longer-term risks.
Treatment plans are personalised. They depend on symptoms, diagnosis, receptor status for cancers, age, comorbidities and patient preferences.
Readers are encouraged to use this information to support informed conversations with a GP, a menopause specialist, an oncology team or a specialist nurse, rather than to replace medical advice.

What hormone therapy is and why it’s used
Here we define how bodily signals control organs and why blocking or replacing those signals can help patients.
How chemical messengers affect the body
Glands such as the ovaries, thyroid and adrenal glands make chemical messengers. These travel in the bloodstream and bind to receptors on target cells to change how those cells behave.
Their effects are wide: they can alter energy use, temperature control, reproduction, mood and metabolism. Small shifts in levels often cause clear symptoms.
Replacement vs blocking approaches
When supply falls, clinicians may use hormone replacement therapy to restore levels and ease symptoms like hot flushes, night sweats and vaginal dryness.
By contrast, cancer treatment uses measures that lower production or block signals so hormone-sensitive tumour cells no longer receive growth instructions.
Terminology and clinical aims
Clinicians sometimes use HT and HRT interchangeably for menopausal care, though HRT is often said when replacing hormones at younger ages. The key difference is intent: one aims to relieve symptoms and protect bone, the other to reduce hormonal stimulation of cancer cells.
How to use this guide: jump to the menopause HRT sections for symptom care or to the cancer sections for details on blocking approaches and specific medicines.
When hormone therapy may be recommended
Decisions about starting this treatment depend on symptoms, test results and a person’s wider health.
Symptoms of menopause and low levels
Menopause care is considered when persistent vasomotor symptoms—such as hot flushes and night sweats—hurt sleep or daily life. Clinicians also look at sleep disturbance, low mood and sexual discomfort alongside measured low levels.
Key triggers include ongoing symptom burden, reduced quality of life and failure of non-drug measures. A doctor will assess clotting history, heart risk and current medicines before recommending treatment.
Hormone-sensitive cancers and receptor-positive cancer cells
Cancer teams only use this approach when a tumour is hormone-sensitive. Tests can show a cancer is receptor-positive, meaning cancer cells carry receptors that let hormones stimulate growth.
Blocking or lowering those signals is used to treat such cancers and can be given before surgery, after to reduce recurrence risk, or to control metastatic disease.
Factors UK doctors consider before prescribing
UK clinicians weigh: cancer type and stage, biomarkers, age, comorbidities, prior treatments and recurrence risk.
Shared decision-making is central. The doctor and patient review benefits, potential risk and route preference so the plan fits the person’s values and goals.
- Who decides: GP, menopause service or oncology team, depending on context.
- Monitoring: Prescribing and follow-up differ between NHS services, but safety checks are similar.
Hormone therapy for menopause: expected benefits
Here is a concise guide to the improvements many women notice after starting menopausal support aimed at stabilising hormones. It sets realistic expectations about what this therapy can do for common symptoms and for bone health.
Relief from hot flashes, night sweats and other symptoms
Many people report a rapid fall in hot flashes and night sweats once levels settle, though the timing varies. Systemic therapy tends to ease vasomotor symptoms and sleep disruption linked to night sweats.
Vaginal dryness and some local issues often need a local approach rather than systemic treatment. Reduced flashes and fewer temperature surges can improve daytime focus and confidence in social or work settings.
Support for bone health and reducing bone loss risk
Oestrogen supports bone density, so using approved therapy can be part of a plan to lower the risk of osteoporosis or osteopenia. This works best alongside weight-bearing exercise and adequate calcium and vitamin D.
Benefit–risk is individual. Clinicians discuss age, baseline risk and personal goals, then review outcomes regularly so doses or routes are adjusted to maintain symptom control with the lowest effective dose.

Types of menopausal HRT: oestrogen-only and combined oestrogen-progesterone
This section describes the main types and how clinicians choose between them.
First step: a clinician confirms whether the person has a uterus. That decision largely determines whether progesterone (a progestin) is needed alongside oestrogen.
Oestrogen-only and when it is used after hysterectomy
After a hysterectomy, oestrogen-only plans are commonly used because there is no womb to protect. This option often suits women who need relief from hot flushes and systemic symptoms.
Oestrogen-only regimens may carry fewer long-term risks than combined regimens in this specific context, but individual factors still guide choice.
Combined oestrogen–progesterone and protecting the uterus
When the uterus is present, adding progesterone or a progestin prevents endometrial overgrowth linked to unopposed oestrogen. This reduces the uterine cancer risk associated with oestrogen-only use.
Clinicians tailor the dose and schedule to balance symptom control with safety, and they review the plan regularly.
Systemic vs local options for different symptoms
Systemic routes enter the bloodstream and treat whole-body symptoms such as hot flushes and sleep disturbance. Local products deliver low doses directly to the vagina and help dryness, soreness and urinary symptoms.
Many people use a combination: a systemic option for vasomotor symptoms plus a local product for vaginal comfort.
| Option | Main use | Key consideration |
|---|---|---|
| Oestrogen-only | Whole-body symptoms after hysterectomy | No uterine protection needed; clinician checks individual risk |
| Combined oestrogen–progesterone | Whole-body symptoms with uterus present | Includes progestin to lower uterine cancer risk |
| Local oestrogen | Vaginal dryness, soreness, urinary symptoms | Low systemic exposure; useful alongside systemic options |
Practical note: conversations about risk cancer and other risks are nuanced. Clinicians assess personal and family history, age and health to agree the safest, most effective plan.
Ways to take hormone therapy: patches, tablets, gels, rings and more
Choosing how to take treatment depends on whether symptoms are generalised or local, and on daily routines. Clinicians offer several options so care fits the person’s life and the symptoms that matter most.
Systemic options for whole-body symptoms
Systemic means the medicine enters the bloodstream and can help the whole body with hot flushes, night sweats and sleep problems.
Common systemic forms include oral tablets, skin patches, sprays and gels. Tablets suit people who prefer a simple daily routine. Patches or gels suit those who dislike pills or who need steady dosing throughout the day.
Local (vaginal) options for dryness and discomfort
Local treatments target the vaginal tissue directly. They usually use a lower dose and reduce dryness, soreness and urinary irritation without much effect on the rest of the body.
Local forms include vaginal rings, creams and low‑dose vaginal tablets. These are useful alongside systemic options, or alone when intimate symptoms are the main concern.
| Delivery form | Main aim | Practical note |
|---|---|---|
| Tablets | Whole‑body symptom control | Simple daily routine; check interactions with other medicines |
| Patches | Steady systemic dosing | Good for those who avoid swallowing tablets |
| Gels & sprays | Systemic option via skin or mucosa | Apply to skin; may need daily use |
| Vaginal ring, creams, tablets | Local relief for dryness and irritation | Lower dose; targeted relief with minimal systemic exposure |
Dose and form are often adjusted over time to balance symptom control and side effects. Patients should discuss other medicines and medical history with their clinician to reduce interaction risk and ensure safe use.

Hormone therapy used to treat cancer: how it works
Stopping production of stimulating compounds or preventing them reaching tumour cells are the two main medical approaches used in endocrine cancer care.
Stopping production versus blocking signals
Reduce production: drugs or surgery lower the body’s supply so tumour cells lack fuel. Removing ovaries or testicles is one example that cuts production across the body.
Block signals: other medicines bind receptors so circulating molecules cannot activate cancer cells.
Why this is a systemic treatment
This approach is systemic: the agents work throughout the body because the signalling molecules travel in the bloodstream. Even a single tumour can be affected by whole‑body changes.
How it differs from surgery and radiotherapy
Surgery removes a defined area. Radiotherapy treats a local region. By contrast, drugs reach distant sites to control microscopic disease or spread.
When it is used
- Before surgery or radiotherapy (neoadjuvant) to shrink a tumour.
- After primary treatment (adjuvant) to cut recurrence risk.
- For recurrence, metastatic disease or palliative control to slow progression.
| Approach | Main aim | Example |
|---|---|---|
| Lower production | Remove systemic source | Oophorectomy, orchidectomy |
| Block signals | Prevent receptor activation | Receptor antagonists |
| Local treatments | Targeted control | Surgery, radiotherapy |
Note: specific drugs are chosen by tumour type, stage and biomarkers; later sections cover breast and prostate details.
Hormone therapy options for breast cancer
When breast cancer cells carry receptors for sex steroids, lowering or blocking those signals becomes a key treatment aim.
Understanding receptor-positive disease
Receptor-positive means the cancer cells have oestrogen and/or progesterone receptors. These receptors let hormones stimulate growth, so targeting them can slow or control the disease.
Aromatase inhibitors
Aromatase inhibitors cut the body’s oestrogen production in post‑menopausal women. Common drugs include anastrozole, letrozole and exemestane.
Selective modulators and degraders
SERMs, such as tamoxifen, modulate the estrogen receptor to block growth in breast tissue. SERDs, for example fulvestrant, degrade the receptor so it cannot signal cancer cells.
Ovary suppression and oophorectomy
Pre‑menopausal patients may receive LHRH agonists (e.g. goserelin) to suppress ovarian production. Surgical removal of the ovaries (oophorectomy) is a permanent option and is considered alongside other treatments.
“Choice of drug or surgery depends on menopausal status, stage and the overall plan.”
Oncology teams tailor duration and sequencing to reduce recurrence risk or manage metastatic disease, with regular follow‑up to monitor cancer control and side effects.
Hormone therapy options for prostate cancer
Treatment for prostate cancer often aims to remove the fuel that drives cancer cells: testosterone. Androgen deprivation therapy (ADT) is the name given to approaches that lower testosterone or block its action so tumour growth slows.
Common delivery routes in the UK
Three main options are used: injections or implants, daily tablets, and surgical removal of the testicles (orchidectomy). Each has trade-offs between convenience, reversibility and permanence.
| Route | Main feature | Consideration |
|---|---|---|
| Injections / implants | Periodic dosing (months) | Reversible; clinic visits needed |
| Tablets | Oral GnRH antagonist option | Daily dosing; avoids surgery |
| Orchidectomy (surgery) | Immediate, permanent testosterone loss | One‑off procedure; no further injections |
LHRH agonists and flare risk
LHRH (also called LHRH) agonists reduce testosterone but can cause a short rise after the first dose. This “flare” may briefly worsen symptoms.
Doctors commonly give anti‑androgen tablets for a few weeks to cover the flare and protect against symptom spikes.
GnRH antagonists for faster suppression
GnRH antagonists, such as degarelix, cut testosterone quickly and avoid flare. Relugolix is an oral agent in this class that offers rapid suppression without the surge seen with agonists.
Practical pathway and monitoring
ADT is often combined with radiotherapy — typically six months around treatment, or longer (up to three years) for higher‑risk disease. Metastatic prostate cancer commonly requires long‑term ADT.
Follow‑up usually includes PSA checks and reviews for side effects such as fatigue, sexual changes, bone thinning and metabolic or cardiovascular risk. Regular monitoring helps manage risks and adjust care.
What to expect during treatment and follow-up appointments
Starting a new course of treatment brings practical steps: an initial assessment, a clear plan and an early review to check how someone responds.
Starting: timelines, dose changes and what “systemic” means
Before treatment begins, a clinician takes a baseline history, records current medicines and orders any needed tests. The chosen medicine and route are explained, including whether it is taken at home or given as an injection at a GP surgery or hospital.
Systemic means the drug works throughout the body. That is why side effects can affect several systems, from mood and bones to skin and energy levels.
Clinicians often start with a lower dose, then adjust based on relief and tolerability. Injection schedules vary — monthly, three‑monthly or six‑monthly — and missing a planned dose can allow testosterone or relevant hormones to rise again, reducing effectiveness.
Monitoring how well treatment is working
Follow‑up checks differ by indication. For menopausal support, reviews focus on symptom control and side effects. For cancer care, monitoring includes clinical review and tumour markers.
Prostate care commonly uses regular PSA blood tests to check response. Teams may change dose or regimen if markers or symptoms suggest the current plan is not working.
When to contact a doctor or specialist nurse between reviews
Contact a doctor or specialist nurse promptly for severe side effects, sudden swelling or pain, signs of clotting, breathlessness, sudden mood changes or rapid symptom worsening.
“Keep injection dates and read medicine instructions — late doses can matter.”
Practical tips: set reminders for oral medicines, note clinic injection dates and ask the team what to do if a dose is late. Good communication helps keep care safe and effective.
Side effects of hormone therapy and how they can affect daily life
Patients may experience several manageable effects which can affect sleep, energy and relationships.
Hot flashes and night sweats
Vasomotor symptoms are common. Sudden warmth, flushing and night sweats can wake someone and disrupt routine.
These side effects vary by drug, dose and personal health. Simple measures—cooling the bedroom, layered clothing and avoiding triggers—help most people.
Fatigue, sleep and concentration
Severe tiredness and poor sleep are often reported. This can make concentrating at work harder and lower overall stamina.
Clinicians may suggest activity pacing, sleep hygiene and checking other causes such as low iron or sleep apnoea.
Mood, anxiety and low mood
Mood swings, anxiety and low mood can follow biological changes and the stress of illness. These are valid and common.
Support from a GP, specialist nurse or counselling service can help manage these effects.
Body changes and physical effects
Suppression of sex steroids often causes weight gain (especially around the waist), reduced muscle mass and loss of body hair.
Sexual side effects include lower libido, erectile difficulties and altered orgasm. Couples benefit from early conversations and signposting to sexual health services.
Breast swelling or tenderness occurs with some anti‑androgen drugs; discuss pain relief or other options if it is distressing.
| Common effect | How it may feel | Practical steps |
|---|---|---|
| Hot flashes / night sweats | Sudden warmth, sleep disturbance | Cooling, trigger avoidance, clothing layers |
| Fatigue & concentration | Tiredness, brain fog | Activity pacing, sleep review, blood tests |
| Sexual & body changes | Lower libido, weight gain, muscle loss | Exercise, diet, sexual health referral |
| Breast changes | Swelling, tenderness | Pain relief, discuss treatment options |
“Not everyone has every side effect; clinicians tailor care to reduce impact.”
Risks and safety: cancer risk, blood clots, heart health and other concerns
All treatments carry potential harms as well as benefits. Clinicians weigh likely symptom relief or cancer control against each person’s baseline profile. Shared decision‑making and regular review make safety checks practical and personal.
Balancing benefits and risks with a clinician
Central principle: a clinician will discuss expected gains and the main risk areas before any treatment starts. This conversation looks at age, medical history, family history and current medicines.
Reviews happen regularly so the plan can change if risks increase or benefits fall. Patients should ask about alternatives and the monitoring schedule.
Bone thinning and fracture risk on long-term suppression
Long‑term lowering of sex steroids can cause bone thinning and raise fracture risk. Bone density checks (DEXA scans) are often advised for people on prolonged treatment.
Prevention: calcium and vitamin D, weight‑bearing exercise and medicines that strengthen bone may be offered where needed.
Cardiometabolic risks: heart disease, stroke, type 2 diabetes and blood clots
Certain regimens can slightly increase the chance of heart disease, stroke, type 2 diabetes and blood clots. For this reason clinicians check blood pressure, lipids, weight and glucose at baseline and during follow‑up.
Smoking cessation, healthy diet and active living are standard risk‑reduction measures discussed in clinic.
Drug safety and handling precautions
Some medicines used in cancer care are handled as hazardous. Patients may get written instructions on storage, safe handling and how to protect others at home.
Pharmacies or clinics will advise what to do with unused drugs and how to manage spills or accidental exposure.
“Decisions balance benefits against personal risks; raise new symptoms promptly and keep review appointments.”
| Risk area | Why it matters | Usual checks or actions |
|---|---|---|
| Bone thinning | Increased fracture risk with long‑term suppression | DEXA scans, calcium/Vit D, lifestyle, bone‑protecting drugs |
| Cardiometabolic | Slight rise in heart disease, stroke, type 2 diabetes | BP, lipids, glucose monitoring, weight management |
| Blood clots | Raised clot risk in some regimens | Assess history, stop smoking, urgent review for swelling/breathlessness |
| Medicines handling | Some agents are classed as hazardous | Written safety advice, safe storage, return/ disposal instructions |
- Distinction: risk discussions differ between menopausal care and cancer settings, but monitoring standards are similar.
- Red flags: chest pain, sudden breathlessness or new, unilateral leg swelling need immediate attention.
- Keep scheduled reviews and report new concerns early — prompt action protects health and keeps treatment safe.
Conclusion
Understanding the goal of treatment makes it easier to ask focused questions at clinic visits.
This guide shows two distinct aims: replacing signals to relieve menopausal symptoms and lowering or blocking signals to control certain cancers. Knowing which goal applies helps a person compare routes, delivery and likely side effects.
Key points covered include types and routes for menopausal care, and the main approaches used in breast and prostate cancer care. Side effects are common but usually manageable; reporting issues early allows dose changes or supportive measures to protect quality of life.
Ongoing monitoring matters — from symptom reviews and blood tests (PSA where relevant) to bone and heart checks. Prepare for appointments by noting symptoms, any side effects and practical preferences for route and schedule.
Safer outcomes come from informed, regular review with a clinician and timely contact with a specialist nurse if concerns arise.
