Hormone therapy for cancer in India
Some cancers need a hormone to grow, and hormone therapy takes that hormone away or blocks it. It is the oldest form of targeted cancer treatment and still one of the most effective, used mainly in breast and prostate cancer. Most of it is tablets or injections, taken for years rather than weeks, which makes it unusually practical for patients treated abroad.

How hormone therapy works
Certain cancers are not merely growing on their own; they are being fed. Most breast cancers carry receptors for oestrogen, and most prostate cancers are driven by testosterone. The hormone binds to the cancer cell and tells it to divide.
Hormone therapy interrupts that instruction, in one of three ways: by reducing how much of the hormone your body makes, by blocking the receptor so the hormone cannot dock, or by stopping the conversion process that produces the hormone in the first place. The cancer is not poisoned as it is with chemotherapy. It is starved.
That difference explains why hormone therapy feels so unlike chemotherapy day to day. There is no hair loss, no cycles of feeling wiped out, and most people continue working. It also explains why it is taken for years: the aim is to keep the cancer suppressed continuously, not to deliver a short intensive assault.
Receptor testing decides everything
This treatment only works if your cancer actually depends on the hormone. That is established by testing your biopsy tissue.
In breast cancer the report will state whether the cancer is ER positive (oestrogen receptor) and PR positive (progesterone receptor), usually alongside HER2 status. Roughly two-thirds to three-quarters of breast cancers are hormone-receptor positive, so this is a common finding rather than a rare one. If your cancer is ER and PR negative, hormone therapy will not help you and a different plan is needed.
In prostate cancer, testing is less about receptors and more about the cancer's stage and risk group, since prostate cancer is assumed to be testosterone-driven at the outset. Your PSA level is then used to track how well the treatment is working.
Hormone therapy for breast cancer
For hormone-receptor positive breast cancer, hormone therapy usually begins after surgery, chemotherapy and radiation are complete, and then continues for five years, sometimes ten. Its job is to reduce the chance of the cancer returning, and it does that job well.
Which drug you are given depends largely on whether you have been through menopause. Before menopause, treatment usually blocks the oestrogen receptor directly, sometimes alongside an injection that switches off ovarian oestrogen production. After menopause, treatment more often blocks the enzyme that produces oestrogen in other tissues. Your oncologist will explain which applies to you and why.
Hormone therapy is also used before surgery in some cases to shrink a tumour, particularly in older patients or where an operation is not immediately possible.
Hormone therapy for prostate cancer
In prostate cancer the same principle applies to testosterone, and the treatment is often called androgen deprivation therapy, or ADT. It is used in several situations: alongside radiotherapy for higher-risk disease, where it makes the radiation substantially more effective; as the main treatment where cancer has spread beyond the prostate; and when PSA rises after earlier treatment.
It is usually given as injections every one to six months, sometimes with tablets. For advanced prostate cancer, newer hormonal agents are now often added to standard ADT, which has improved outcomes considerably compared with ADT alone.
Side effects, honestly
Hormone therapy is easier than chemotherapy but it is not free of consequences, and because you take it for years the effects accumulate in a way short treatments do not. Being told this properly at the start makes it far easier to stay on treatment, and staying on treatment is what makes it work.
Common in breast cancer treatment
- Hot flushes and night sweats, often the most disruptive effect
- Joint aches and stiffness, particularly with aromatase inhibitors
- Vaginal dryness and reduced libido
- Tiredness and mood changes
- Bone thinning over years, so bone density is monitored
Common in prostate cancer treatment
- Hot flushes
- Loss of libido and erectile difficulty
- Tiredness and loss of muscle strength
- Weight gain, particularly around the middle
- Bone thinning, and mood changes
Most of these are manageable, and manageable is the important word. Hot flushes, bone thinning and joint pain all have specific treatments. Some patients stop hormone therapy early because nobody told them the effects could be treated. Ask your oncologist what to do about each one before you start, and ask who you contact once you are home.
Why it lasts years, and how that works from abroad
Five to ten years of daily tablets is not something anyone completes during a trip to India, and that is fine. Hormone therapy is the most portable cancer treatment there is.
A realistic arrangement looks like this: your diagnosis, surgery and any chemotherapy or radiation are done in India; your oncologist establishes the hormone therapy plan and starts you on it; and you continue the tablets at home, with periodic monitoring locally. That monitoring is straightforward, usually blood tests, a PSA level for prostate cancer, and bone density checks over time.
Before you fly home, get three things in writing: the exact drug and dose, how long you are to take it, and what monitoring is needed and how often. Ask also what to do if you cannot obtain that specific drug locally, since alternatives usually exist. Generic versions of most hormone therapy drugs are widely available and inexpensive, which is one reason this treatment is practical for patients in countries where newer cancer drugs are hard to get.
What it costs
Hormone therapy is among the least expensive cancer treatments, particularly compared with targeted drugs or immunotherapy. Most of the established drugs are available as generics, and India's pharmaceutical industry produces them at low cost.
Because treatment runs for years, the figure that matters to you is the monthly or annual cost rather than a one-off price, and whether you can obtain the drug at home. Ask your oncologist for both, in writing, before you travel back. You receive a written estimate covering your treatment plan before you commit, with no fee to us built in; the hospital pays us, so your bill is never marked up.
Questions patients ask
Is hormone therapy chemotherapy?
No. Chemotherapy poisons rapidly dividing cells throughout the body. Hormone therapy removes or blocks the specific hormone a cancer depends on, effectively starving it. That is why there is no hair loss and why most people feel well enough to continue working. They are sometimes used in sequence, chemotherapy first and hormone therapy afterwards for years.
How do I know if it will work for me?
Your biopsy report answers this. In breast cancer, it will state whether the cancer is ER positive and PR positive; if both are negative, hormone therapy will not help and a different plan is needed. Prostate cancer is generally assumed to be testosterone-driven, so the question there is less whether it will work and more when to start it.
Why do I have to take it for so many years?
Because it works by continuous suppression rather than a short intensive attack. Hormone-receptor positive breast cancer can return many years after the original treatment, and staying on hormone therapy through that period is what reduces the risk. Stopping early reduces the benefit, which is why managing side effects properly matters so much.
Will it affect my sex life?
Often, yes, and you deserve a direct answer. In prostate cancer, reducing testosterone commonly lowers libido and causes erectile difficulty. In breast cancer, vaginal dryness and reduced libido are common. These are among the most under-discussed effects and among the most treatable, so raise them explicitly with your oncologist rather than assuming nothing can be done.
Can I continue the treatment in my own country?
Yes, and this is the normal arrangement for international patients. Hormone therapy is tablets or periodic injections, so it travels well. Before you fly home, get the drug name, dose, duration and monitoring schedule in writing, and ask what alternatives exist if that specific drug is unavailable locally. Most hormone therapy drugs are widely available as inexpensive generics.
What happens if the cancer stops responding?
Cancers can become resistant to hormone therapy over time. This is anticipated rather than a failure, and it is not the end of treatment. Options include switching to a different hormonal drug, adding a targeted agent, or moving to chemotherapy. In advanced prostate cancer in particular, several successive hormonal treatments are now standard.
Will it weaken my bones?
It can, over years, in both breast and prostate cancer treatment. This is why bone density is monitored and why calcium, vitamin D or bone-protecting medication may be recommended. It is a known and managed effect rather than an unexpected one, so ask what monitoring is planned for you and make sure it can be arranged at home.
