A type of cancer can develop for years without clear symptoms. This means many people may not notice the illness until much later. Health authorities now say that even small changes in bathroom habits can be important warning signs that should be checked by a doctor.
Cancer can develop slowly

According to the NHS, prostate cancer often grows very slowly. Because of this, the disease may be present for many years without obvious symptoms. This is why it is important to know the signs that may appear over time.
Three key signs

The NHS has highlighted three main symptoms that men should be aware of when it comes to bathroom habits. These include needing to urinate more often, straining when urinating, and feeling that the bladder has not fully emptied.
Needing to urinate more often

One possible warning sign is an increased need to go to the bathroom. If someone suddenly needs to urinate more frequently than usual, it may be a change worth discussing with a doctor.

Straining during urination

Another symptom can be difficulty when trying to urinate. If it becomes harder to start or maintain urination, experts say it should be checked by a medical professional.
Feeling the bladder is not empty

Some men may feel that their bladder is still full even after using the bathroom. According to the NHS, this sensation can be an important symptom to be aware of.
Weak urine flow

Other symptoms may also appear alongside the main warning signs. One of these is a weak urine stream, where the flow of urine becomes slower or weaker than normal.
Stop start urination

Another possible symptom is urine that stops and starts during a single bathroom visit. This change can sometimes signal issues affecting the urinary system.

Night time urination

Frequently needing to urinate during the night can also be a possible sign. If someone begins waking up regularly to use the bathroom, it may be something to monitor.
Additional symptoms

The NHS also lists several other possible symptoms linked to prostate cancer. These include erectile dysfunction, blood in urine or semen, and pain in the lower back.
Unexplained weight loss

Unintentional weight loss can also be a warning sign. Losing weight without trying may sometimes indicate an underlying health issue.
Most common in older men

Prostate cancer most often affects older men. According to the NHS, it is most commonly diagnosed in men aged 75 or older.
