# Prostate cancer (metastatic)
What is it
Metastatic prostate cancer (medical term: metastatic prostate cancer) is cancer that has spread from the prostate to other parts of the body. The prostate is a small gland organ that only men have; it sits below the bladder and produces fluid that is part of semen.
In metastatic prostate cancer, cancer cells from the prostate have entered the bloodstream or lymphatic system and have settled elsewhere. This usually happens in the bones (especially pelvis, spine and ribs), but cancer can also spread to the lungs, liver or other organs.
It is important to know that metastatic prostate cancer is not the same as a new cancer in that other location — it is always prostate cancer cells that have spread.
Doctors distinguish two situations:
- **Metastatic hormone-sensitive prostate cancer (mHSPC)**: cancer that still responds well to hormone treatment.
- **Metastatic castration-resistant prostate cancer (mCRPC)**: cancer that no longer responds to hormone therapy, even though testosterone levels are kept low.
Causes
Prostate cancer develops because cells in the prostate begin to divide uncontrollably. Why this happens is not fully understood, but various factors play a role:
- **Age**: prostate cancer is much more common as men get older.
- **Family history**: if someone in your immediate family has had prostate cancer, your risk is greater.
- **Certain genes**: some inherited gene mutations significantly increase the risk.
- **Ethnic background**: men of African descent more often have more aggressive forms.
- **Hormonal factors**: testosterone plays a role in the development of prostate cancer.
Whether someone develops prostate cancer and whether it spreads depends on many factors: how aggressive the cancer is, how early it is detected, and how well treatment works.
How the disease progresses
Prostate cancer can be present for a long time without symptoms. When the diagnosis of "metastatic" is made, it means that tests (blood tests, imaging) have shown that cancer has already spread beyond the prostate.
The disease progresses in phases:
**Hormone-sensitive phase**: at first, the cancer usually responds well to hormone treatment, aimed at lowering testosterone levels. During this phase, the cancer can remain under control for a longer time.
**Transition to castration resistance**: over time, the cancer can undergo changes so that it no longer responds to hormone therapy. This can take months to years. In this phase, the PSA level (a substance in the blood) has started to rise again despite low testosterone.
**Castration-resistant phase**: the cancer continues to grow despite continued hormone treatment. Now other medications are used, such as chemotherapy or newer targeted medicines.
The disease can have ups and downs: periods when the cancer is somewhat under control and periods when it grows more quickly. This is very individual.
Symptoms by phase
Many men with metastatic prostate cancer initially have **no symptoms** — the disease is discovered because PSA rises or imaging shows changes.
**Symptoms can develop as a result of:**
- **Bone metastases**: bone pain (especially in the pelvis, lower back or ribs), sometimes a feeling of weakness in the legs, fractures.
- **Lymph node swelling**: enlarging nodes can cause pressure; sometimes noticeable swelling in the abdomen or thighs.
- **Organ involvement**: headache (with brain metastases, rare), shortness of breath (with lung involvement), fatigue.
- **General symptoms**: tiredness, weight loss, night sweats, loss of appetite.
- **Side effects of treatment**: depending on which therapy has been started.
It's important to recognize that symptoms don't always appear at the same time as disease progression — sometimes the disease has progressed further than you feel. Conversely, symptoms can also come from something else.
What it means for daily life
Metastatic prostate cancer affects many aspects of life, but the extent depends heavily on how rapidly the disease is progressing, what treatment is given, and how well it works.
**Work and activities**: many men can initially continue their work, especially in hormone-sensitive phases. Later, fatigue, side effects from medications, or physical limitations (bone pain) can make work difficult or impossible.
**Physical wellbeing**: depending on the phase and treatment, men may experience fatigue, probably the most common experience. Bone pain can limit movement. Some medications cause side effects such as hot flashes, mood changes, or physical changes.
**Sexuality and relationships**: hormonal therapy can cause erectile dysfunction and loss of libido. This can affect intimate relationships and self-image.
**Mental wellbeing**: the diagnosis of "metastatic" often triggers strong emotions: fear, uncertainty about the future, loss of control. Depression and anxiety disorders are not uncommon. Professional support (psychologist, psychiatrist) can be valuable.
**Medical procedures**: regular doctor and hospital visits, blood tests, imaging, and possible hospitalizations are part of it. This requires time and energy.
**Family and loved ones**: the diagnosis also affects your partner and loved ones. Communication about what you feel and what you need can help.
Many men find they need to be flexible: adjust plans when you have less energy, prioritize what matters to you.
Outlook
The outlook for metastatic prostate cancer is highly individual and depends on many factors: how aggressive the cancer is, where it's located, how well the initial treatment works, age, and overall health.
**General impression**: metastatic prostate cancer is incurable, but for many men it's a chronic disease where years of reasonable quality of life are possible, especially if the cancer remains hormone-sensitive. Others experience a more rapid progression.
Survival statistics are difficult: international studies show that men with mHSPC (hormone-sensitive) in combination treatments reach median survivals of 3–5+ years, but this says nothing about your personal situation. Also: statistics change as new treatments become available and detection improves.
**Important note**: population-level survival statistics say nothing about how long one person will live. Two men with the same diagnosis can follow very different paths.
Treatment aims to:
- Slow disease progression
- Relieve symptoms and pain
- Maintain quality of life as much as possible
- Prevent or treat complications
Regular discussion with your treatment team helps monitor how the disease responds to treatment and when adjustments are needed.
Frequently asked questions
**Is metastatic prostate cancer always serious?**
Metastatic prostate cancer is more serious than cancer confined to the prostate, because it has already spread beyond that organ. But "serious" is not the same as "short life". Some men have reasonable health for years, especially in the initial, hormone-sensitive phase. Others experience faster progression. Your own doctor can tell you more about your specific situation.
**Can I still live a normal life?**
That depends on how rapidly your cancer is progressing and how your body responds to treatment. Many men can continue parts of their daily life, though you may sometimes need to adjust expectations. Work, hobbies, travel — some things continue, others are adapted or postponed. It's important to be honest with yourself about what is and isn't possible at each moment.
**What happens if the cancer no longer responds to hormonal therapy?**
Then there are other treatments available: chemotherapy, targeted medicines, and radiological therapies (such as radioactively labeled agents that detect and destroy cancer tissue). Your doctor will discuss which options are relevant for you.
**How long will I undergo this treatment?**
That varies greatly. Some treatments are given for weeks or months, others are continued for months or years as long as they are effective and side effects remain acceptable. Regular discussions with your team will determine what is best for you.
