12 Signs of Prostate Cancer

2. Very Weak Urine Flow

A very weak urine flow can be an early sign that something is affecting your prostate. The prostate sits below your bladder and surrounds the urethra, the tube that carries urine out of your body. When the prostate grows larger than usual, it can press on the urethra and make it harder for urine to pass through.

You might notice your urine stream starts and stops often, or that it dribbles instead of forming a steady flow. You may also find yourself standing at the toilet longer than usual, trying to empty your bladder completely. Sometimes, this weak flow comes with a feeling that your bladder still has urine left, even after finishing.

A weak flow does not always mean prostate cancer. Noncancerous prostate enlargement or infections of the prostate or urinary tract can also cause this. Because prostate cancer may develop without clear symptoms at first, do not ignore changes in your urination.

If you experience these changes often, or if they get worse, a healthcare provider can check your prostate’s size and health using simple tests.

3. Frequent Urination

You may notice that you are going to the bathroom more often than usual, especially at night. This condition, called nocturia, can cause you to wake up several times to urinate, which may interrupt your sleep. An enlarged or irritated prostate can press against the bladder or the urethra, the tube that carries urine out of your body, causing frequent urination.

When prostate cells grow abnormally, they can narrow the urinary passage, making the bladder work harder to empty itself. This can make you feel like you need to urinate even when your bladder is not full. You might also experience that you cannot completely empty your bladder. In some cases, you may feel an urgent or sudden need to urinate that is difficult to control.

4. Hematuria

Hematuria means blood in your urine. You may notice your urine looks pink, red, or dark brown. Sometimes the blood is visible, but other times it may appear normal and only a lab test can detect it.

In prostate cancer, a tumor can grow and affect nearby blood vessels or tissues, leading to ruptures and causing bleeding in the urinary tract. Even a small amount of blood can signal a change that needs to be checked.

Seeing blood in your urine can be alarming, but it does not always mean you have prostate cancer. Infections, kidney or bladder stones, or an inflamed urinary tract can also cause this. If you find blood in your urine, your doctor may use urine tests, imaging studies, including a physical exam, to find the cause and rule out other conditions.

5. Blood in Semen and Painful Ejaculation

Blood in semen, also called hematospermia, can cause concern but is not always a sign of something serious. Minor irritation or infection in the prostate, urethra, or seminal vesicles often causes it. Sometimes, it may appear after a medical procedure such as a prostate biopsy or vasectomy.

If you see a pink, red, or brown tint in your semen, some bleeding occurred somewhere in your reproductive tract. The color can depend on how recent the bleeding is. You might also feel discomfort in your lower abdomen, pelvis, or the area between your scrotum and anus.

Painful ejaculation sometimes happens with the same conditions that cause blood in semen. Infection, swelling of the prostate (prostatitis), or an enlarged prostate can make ejaculation hurt. This pain may come with other urinary symptoms like a weak urine stream or a burning feeling when you urinate.

Although these symptoms often clear up without treatment, do not ignore them. In rare cases, these signs could point to prostate cancer or another serious condition that requires medical evaluation.

6. Fatigue and Weight Loss

You may notice that you feel tired more often, even after getting enough rest. Changes in your body as it fights disease or how your body uses energy differently when cancer is present can cause this kind of fatigue. It can also appear gradually, making daily tasks feel harder than before.

Unexplained weight loss can be another warning sign. You might eat the same amount of food yet still lose pounds without trying. Cancer cells can affect how your body breaks down and uses nutrients. The weight loss often comes slowly, but you may notice looser clothing or a smaller appetite.

Fatigue and weight loss can have many causes, including stress or other illnesses, but they may also signal a change in your prostate health that needs attention.

7. Swollen Legs and Feet

Swelling in your legs or feet can sometimes point to advanced prostate cancer. When cancer spreads to the lymph nodes in the pelvis, it can block normal fluid movement. Fluid buildup causes tissues in your lower body to swell.

You might notice your shoes fitting tighter or a feeling of heaviness in your legs. The skin around your ankles may look stretched or shiny. The swelling can be mild at first but may worsen over time if not treated.

This kind of swelling is called lymphedema. It usually appears in the lower legs or feet and can affect one or both sides. Sometimes the area can feel tender or uncomfortable when you walk or stand for long periods.

Swelling from prostate cancer differs from temporary puffiness caused by sitting or standing too long. It might not go away after resting or elevating your legs. Reporting this change to your doctor helps them with the diagnosis.

8. Erectile Dysfunction

Erectile dysfunction can sometimes signal prostate cancer, especially when it appears suddenly or becomes worse over time. Blood flow or nerve function in the penis may be affected. While aging, stress, or certain health conditions are possible causes, prostate cancer may interfere with the nearby nerves or tissues that help control erections.

You may notice difficulty getting or keeping an erection that’s firm enough for sexual activity. This can affect confidence and relationships, but it’s important to see it as a possible health warning rather than just a sexual issue.

Treatments for prostate cancer such as surgery, radiation, or hormone therapy can also lead to erectile dysfunction. These treatments can lower testosterone levels or damage sensitive nerves near the prostate.

Doctors may recommend different ways to manage erectile dysfunction, including lifestyle changes or certain medication classes that improve blood flow. Talking openly with your healthcare provider allows you to understand what’s causing the problem and find an approach that fits your needs.

9. Numbness or Pain in the Lower Body

You might notice aching, soreness, or tingling in your lower back, hips, thighs, or legs. Sometimes this pain spreads from one area to another and can make it harder to move or sit for long periods. It can feel sharp or dull depending on how nerves or nearby tissues are affected.

When prostate cancer grows, it can press on nearby nerves or bones. This pressure may cause numbness or weakness in the lower body. In some men, the pain can feel similar to muscle strain or arthritis, making it easy to overlook. If cancer spreads to the bones or spine, you may experience more intense, ongoing discomfort.

You may notice stiffness or reduced movement in your lower body. Pain that does not improve with rest or simple care should be checked by a doctor. Tracking where and when you feel numbness or pain can help your healthcare provider understand what’s happening.

10. Bone Pain

Bone pain can be an important warning sign that prostate cancer has spread to the bones. You may feel a deep, aching pain in your hips, back, ribs, or legs. It can come and go at first but may become more constant over time.

This type of pain is different from muscle soreness or joint stiffness. It may feel stronger at night or after movement. Unlike common aches, bone pain often does not improve with rest or usual pain relievers.

If you notice bone pain along with tiredness, weight loss, or weakness, tell your healthcare provider. These symptoms can help identify whether cancer has spread to other areas of the body.

In some cases, imaging tests such as X-ray, bone scan, or MRI help determine if cancer cells have reached the bones. Early detection of bone involvement allows doctors to plan treatment that helps manage pain and minimize the effects of cancer, especially the discomfort.

11. Incontinence

Incontinence means losing control of your bladder. You may notice small leaks when you cough, laugh, or lift something heavy. Some men suddenly need to urinate and cannot make it to the bathroom in time. A tumor growing near the bladder or urethra can cause this problem.

The tumor in the prostate presses on these areas and limits how well they hold or release urine. In some cases, treatments for prostate cancer, such as surgery or radiation, weaken the muscles that help control urination. You might also wake up more often at night to urinate or feel that your bladder never fully empties.

There are two main types of incontinence associated with prostate problems. Stress incontinence occurs when urine leaks during physical movement or any action that puts pressure on the bladder, such as coughing, lifting, or exercising. Urge incontinence, on the other hand, involves a sudden, intense need to urinate followed by an involuntary loss of control.

12. Uncomfortable Sitting Position

You may notice that sitting for long periods becomes painful or awkward. Swelling or pressure in the prostate area can cause this feeling. When the gland grows larger or becomes irritated, it presses against surrounding tissues and nerves, making sitting uncomfortable.

Some men describe a dull ache or pressure between the scrotum and the anus. Others feel pain that spreads to the lower back, hips, or upper thighs. The discomfort often gets worse when sitting on hard surfaces or after being still for a long time.

If sitting causes more pressure, or you have other urinary changes, such as trouble starting to urinate or pain during urination, talk to your doctor. Your doctor can check whether the discomfort relates to prostate enlargement, infection, or possible signs of prostate cancer.
