Prostate Cancer Causes
The prostate is a walnut-sized exocrine gland. This means that its fluids and secretions are intended for use outside of the body.
The prostate produces the fluid that nourishes and transports sperm on their journey to fuse with a female ovum, or egg, and produce human life. The prostate contracts and forces these fluids out during orgasm.
The protein excreted by the prostate, prostate-specific antigen (PSA), helps semen retain its liquid state. An excess of this protein in the blood is one of the first signs of prostate cancer.
The urethra is tube through which sperm and urine exit the body. It also passes through the prostate.
As such, the prostate is also responsible for urine control. It can tighten and restrict the flow of urine through the urethra using thousands of tiny muscle fibers.
Prostate Cancer Symptoms or Signs of Prostate Cancer
There more often than not aren’t any early cautioning signs for prostate malignancy. The developing tumor does not push against anything to cause torment, so for a long time the sickness might be quiet. That is the reason screening for prostate tumor is such an imperative point for all men and their families.
But in some case there is symptoms of prostate cancer or sign of prostate cancer :
- frequent urges to urinate, including at night
- difficulty commencing and maintaining urination
- blood in the urine
- painful urination and, less commonly, ejaculation
- difficulty achieving or maintaining an erection may be difficult
Advanced prostate cancer can involve the following symptoms:
- bone pain, often in the spine, femur, pelvis, or ribs
- bone fractures
If the cancer spreads to the spine and compresses the spinal cord, there may be:
- leg weakness
- urinary incontinence
- fecal incontinence
PSA test or Prostate-Specific Antigen
Prostate-specific antigen or PSA, is a protein produced by normal, as well as malignant, cells of the prostate gland. The PSA test measures PSA levels in blood. A number of benign (not cancerous) conditions can cause a man’s PSA level to rise. The most frequent benign prostate conditions that cause an elevation in PSA level are prostatitis (inflammation of the prostate) and benign prostatic hyperplasia (BPH) (enlargement of the prostate). There is no evidence that prostatitis or BPH leads to prostate cancer, but it is possible for a man to have one or both of these conditions and to develop prostate cancer as well.
