Prostate cancer is one of the most common cancers affecting men, but early prostate cancer often causes no noticeable symptoms. When symptoms do occur, they may resemble those caused by other prostate conditions, such as an enlarged prostate or prostatitis.
Understanding the possible prostate cancer symptoms and warning signs can help men recognize changes and discuss them with a healthcare professional. However, having one or more of these symptoms does not necessarily mean that a person has prostate cancer.
What Are the Early Signs of Prostate Cancer?
Early prostate cancer often causes no noticeable symptoms. A review found that prostate cancer can be difficult to identify from symptoms alone because early disease may be asymptomatic (1).
Possible signs may include:
Difficulty starting urination
A weak or slow urine stream
Frequent urination, especially at night
Difficulty completely emptying the bladder
Blood in the urine or semen
These symptoms are not specific to prostate cancer and can also occur with conditions such as benign prostatic hyperplasia (BPH) or prostatitis. If symptoms persist, speak with a healthcare professional for proper evaluation.
Symptoms That May Occur With Prostate Cancer
The symptoms of prostate cancer can vary depending on the stage and location of the disease.
1. Difficulty Urinating
A person may have trouble starting or stopping urine flow. The urine stream may also become weaker than usual.
2. Frequent Urination
Needing to urinate more often, particularly during the night, can be a possible sign of a prostate or urinary problem.
3. Weak or Interrupted Urine Flow
Some men may notice that their urine stream is weaker than before or stops and starts during urination.
4. Feeling That the Bladder Has Not Emptied
A persistent sensation that urine remains in the bladder after urinating can occur with several prostate or urinary conditions.
5. Blood in Urine or Semen
Blood in the urine or semen should be medically evaluated. It can have several causes, including conditions unrelated to cancer.
6. Painful Urination
Pain or burning during urination can occur with several prostate or urinary conditions, including infections and prostatitis. It is not specific to prostate cancer.
7. Persistent Pain in the Back, Hips, or Pelvis
Persistent pain in the back, hips, or pelvis can occur in more advanced prostate cancer, particularly when the cancer has spread to the bones. Unexplained or persistent pain should be evaluated by a healthcare professional.
Does Prostate Cancer Cause Urinary Problems?
It can, but urinary problems are not specific to prostate cancer.
The prostate is located below the bladder and surrounds part of the urethra. Changes involving the prostate can affect urine flow.
Possible urinary symptoms include:
Frequent urination
Urgency to urinate
Difficulty starting urination
Weak urine flow
Interrupted urine flow
Difficulty completely emptying the bladder
Increased nighttime urination
Blood in the urine
An enlarged prostate, urinary infection, and other conditions can cause similar symptoms. Therefore, urinary symptoms should be evaluated rather than assumed to be cancer.
Can Prostate Cancer Cause Pain?
Early prostate cancer usually does not cause pain. Persistent pain may occur when prostate cancer becomes more advanced or spreads to other parts of the body.
Pain associated with advanced disease may occur in areas such as:
Lower back
Hips
Pelvis
Upper legs
Bones
Persistent or unexplained pain should be evaluated by a healthcare professional.
What Are Advanced Prostate Cancer Symptoms?
When prostate cancer progresses, symptoms can become more noticeable. Depending on where the cancer has spread, possible symptoms may include:
Persistent bone or back pain
Unexplained weight loss
Extreme or persistent tiredness
Loss of appetite
Swelling in the legs
Difficulty urinating
Blood in the urine
Erectile difficulties
Weakness or numbness caused by pressure on nerves or the spinal cord
Loss of bladder or bowel control when cancer affects the spinal cord
Loss of bladder or bowel control, weakness, or numbness may indicate pressure on the spinal cord and requires urgent medical attention.
Is Frequent Urination a Sign of Prostate Cancer?
Frequent urination can occur with prostate cancer, but it is much more commonly associated with other prostate or urinary conditions.
For example, benign prostatic hyperplasia (BPH), which is a non-cancerous enlargement of the prostate, can cause frequent urination and a weak urine stream.
If urinary changes are persistent, worsening, or unusual for you, speak with a healthcare professional to determine the cause.
Difference Between Prostate Cancer and Enlarged Prostate
Although both can affect urination, there are some important differences between them:
Point | Prostate Cancer | Enlarged Prostate (BPH) |
What it is | Abnormal growth of cells in the prostate | Non-cancerous enlargement of the prostate |
Early symptoms | May have no noticeable symptoms | Urinary symptoms are often noticeable |
Urine flow | Weak or interrupted flow may occur | Weak or interrupted flow is common |
Frequent urination | May occur | Common |
Nighttime urination | May occur | Common |
Difficulty starting urination | May occur | Common |
Blood in urine | May occur | May occur |
Pelvic or back discomfort | More concerning in advanced disease | Less typical |
Nature | Requires medical evaluation | Common prostate-related condition, particularly with increasing age |
A healthcare professional can determine whether further evaluation or testing is appropriate.
When Should You See a Doctor?
Consider speaking with a healthcare professional if you experience:
Persistent changes in urination
Blood in your urine or semen
Unexplained erectile difficulties
Persistent pain in the back, hips, or pelvis
Unexplained weight loss
Symptoms that are getting worse
Men who are concerned about their prostate cancer risk can discuss screening with a healthcare professional, even if they have no symptoms. Whether PSA testing is appropriate depends on factors such as age, family history, and individual risk.
How Is Prostate Cancer Diagnosed?
Symptoms alone cannot confirm prostate cancer.
Depending on the individual's situation, a healthcare professional may recommend:
Medical history and physical examination
Prostate-specific antigen (PSA) blood test
Digital rectal examination (DRE)
Prostate biopsy, which is generally needed to confirm whether prostate cancer is present
A PSA test can provide useful information, but an elevated PSA level does not automatically mean prostate cancer. Research shows that PSA testing has limitations in detecting prostate cancer in symptomatic men (2).
Who Is at Higher Risk of Prostate Cancer?
Risk can increase with factors such as:
Increasing age
A father, brother, or son with prostate cancer
Certain inherited gene changes, including BRCA1 or BRCA2
Certain ancestry-related risk factors
Key Takeaway
Prostate cancer may not cause noticeable symptoms in its early stages. Urinary changes, blood in urine or semen, erectile difficulties, and persistent pain can occur, but these symptoms may also result from other conditions.
If you notice persistent or unusual changes, speak with a healthcare professional rather than trying to diagnose the cause yourself. Early medical evaluation can help identify the underlying problem and determine whether further testing is needed.

Frequently Asked Questions
What is the first warning sign of prostate cancer?
There may be no first warning sign because early prostate cancer often causes no symptoms. When symptoms occur, urinary changes such as difficulty urinating or a weak urine stream may be noticed.
What are some early warning signs of prostate cancer?
There are not three symptoms that reliably identify early prostate cancer. Possible symptoms include difficulty urinating, frequent urination, and a weak or interrupted urine stream, but these can also occur with non-cancerous prostate conditions.
Does prostate cancer cause frequent urination?
It can, but frequent urination has many possible causes, including an enlarged prostate and urinary conditions. Persistent urinary changes should be evaluated.
What does prostate cancer pain feel like?
Early prostate cancer commonly does not cause pain. Advanced disease may cause persistent pain, particularly in the back, hips, pelvis, or other bones.
Can you have prostate cancer without symptoms?
Yes. Early prostate cancer frequently has no noticeable symptoms. This is one reason discussions about risk and appropriate screening with a healthcare professional are important.
