If it grows large enough, it may press on the urethra, the tube that carries urine from the bladder. This may make the urine flow weaker or slower or make men have to urinate more often, especially at night. In the large majority of cases, an increase in the size of the prostate and a change in urine flow do not mean you have cancer. They are just a normal part of aging. In some cases, a growth in the prostate is cancerous.
Prostate cancer is different in different men.
Sometimes the cancer stays in the prostate gland and has little or no effect on how a man feels or how long he lives. Some men with prostate cancer have no symptoms - in other words, it is possible to have prostate cancer without the prostate being enlarged, without urinary problems, and without pain. About seven out of every 10 men diagnosed with prostate cancer will die from other causes such as heart disease, stroke or old age. Although they may not die from prostate cancer, some of these men may develop symptoms of the disease before they die of other causes. Prostate cancer can also be serious and fatal.
