Prostate cancer affects the prostate gland in men. In usual circumstances, prostate cancer can be detected early with screening. Unfortunately, if a recent study is to be believed, one in every nine men in the US will soon be diagnosed with prostate cancer. Amongst American men, it is the 2 ^nd leading cause of death due to cancer. 

Common and rare signs of prostate cancer
In most men, the early stages of cancer do not showcase any sign, and the disease begins to show symptoms only in later stages. There are a few signs and symptoms which are commonly seen in men. However, there are a few rare signs of prostate cancer too. Here, we will discuss both of them. 

Usual symptoms of prostate cancer
Some of the common signs of prostate cancer include the following. 

• Difficulty in peeing, including weak or slow urinary stream
• Peeing more often than usual, particularly at night 
• Presence of blood in the semen or urine
• Erectile dysfunction, that is, difficulty in getting an erection
• Numbness or weakness in the feet or legs
• Loss of bowel or bladder control 

Rare symptoms of prostate cancer

• Constipation
  At all times, we know when we eat something that may disturb our digestive system. However, if you are eating just fine, and despite that, you are experiencing frequent constipation, it is wise to see a doctor at the earliest. In men who have constipation because of prostate cancer, the same is accompanied by pain or pressure on the rectum. 

• Your semen release is affected
  Low fluid ejaculation is also seen in a few men. Thus, it is a rare sign of prostate cancer. However, you need to know that low semen release is not always a symptom of prostate cancer. The semen count can also be down because of insufficient hormone levels, retrograde ejaculation, meaning that the semen goes back in the bladder and weak pelvic muscles. So, if the semen count is affected, you should speak to the doctor to know more about the underlying issue. 

• Pain in the lower back
  Usually, when people have a lower backache, they automatically assume it may be because of their poor sleeping pattern or a muscle pull at the gym. However, many do not know, but stiffness or pain in the lower back is indeed one of the first signs of prostate cancer, and should not be ignored. But, how would you know if it is a cancer-driven pain? If the pain is caused by prostate cancer, it will be deep and dull.

• Incomprehensible weight loss
  Another potential symptom of prostate cancer is incomprehensible weight loss. Weight loss usually starts when prostate cancer is in the later stages and has spread beyond your prostate gland.  
• Finding a comfortable sitting position now seems hard
  Experiencing pain or discomfort while sitting is a rare sign of prostate cancer. It arises when the prostate gland starts pressing onto the other areas of the pelvis.
