It is estimated that one in seven men will develop prostate cancer at some point in their lifetime. And the difference between beating the cancer or succumbing to it is early detection. While many men are aware of the common symptoms of prostate cancer, such as an enlarged prostate, pain when urinating, or loss of bladder control, many men don't know some of the other symptoms associated with this type of cancer. Learning about these symptoms may help raise your awareness, so you get screened by a doctor if you think anything is wrong. Here are three lesser known signs of prostate cancer.

Erectile Dysfunction

One of the lesser known signs of prostate cancer is erectile dysfunction, or trouble getting an erection. As men age, this is something that can naturally happen. And fortunately, there are pills to help with this problem. Unfortunately, many men take this symptom as a sign of aging, rather than a sign that something else is wrong. If you experience erectile dysfunction, talk to your doctor. It may be age-related, but it may also be related to a medical condition that is not diagnosed, such as prostate cancer.

Painful Ejaculation

Another lesser known sign of prostate cancer is painful ejaculation. When a man ejaculates, it should be a good feeling or sensation. However, if you experience pain, you need to make an appointment with your doctor. Painful ejaculation can be related to sexually transmitted diseases or more serious medical conditions, such as prostate cancer.

Swelling in the Legs, Hips, or Pelvic Region

The last sign that you may have prostate cancer without even realizing it is swelling in the upper legs, hips, or pelvic region. Unfortunately, this is typically a sign that the cancer is either large or is spreading to other parts of the body. If you experience any swelling in these regions or feel bone pain in these areas, especially if they are coupled with urinary or penile issues, be sure to seek treatment from a doctor.

Unfortunately, many symptoms of prostate cancer are similar to other illnesses that are not as serious. Many people who experience some of these symptoms may think that they are simply aging or have a urinary tract infection. Learning what the signs and symptoms of prostate cancer are may help open your eyes and get you to seek treatment from a doctor if you have any of these symptoms. While you very well could be experiencing a minor medical problem, it is better to be safe than sorry. If it does turn out to be prostate cancer, starting treatment early can help increase your chance of beating the cancer.
