The prostate cancer is a type of cancer that affects only the male specific seminal fluid gland; cancer is considered an abnormal condition of the body resulting after the uncontrollable growth process and multiplication of the cancerous cells, in the first stages the developed tumor being named primary or organ-confined because it is found only in the primary site, here being the prostate organ.

There is a situation when the spreading of the tumor was so fast and complex that doctors find it hard to identify the primary site of the cancer: this is what we call cancer of unknown primary.

When cancer is metastasized that basically means that the chances to cure this disease are almost zero. If the cancer is treated by comes back in the form of two or more metastatic tumors then this stage is called metastases.

If cancer is diagnosed the grading process and after it the staging process will help doctors make the right decision when prescribing a treatment; each treatment will be prescribed depending on the personal preferences of the patient, his medical and metabolic characteristics and the stages of the cancer.

Since this type of cancer has no early symptoms or signs to make it noticeable, doctors recommend for men over forty to routinely do the screening tests or the prostate biopsy for an accurate result.

When the cancer becomes locally advanced or metastatic the symptoms often reported are: prostate inflammation, burning or pain while urinating, prostate blockage, bacterial prostatitis, urine odor, frequent urination or weak urine stream, prostatitis, blood in urine or semen, prostate-related urinary dribbling, back pains, stiffness, ache, enlarged prostate, prostate pain, painful ejaculation, compression of the spine, leg pain, abdomen and chest pain.

This spreading process is done through the lymph vessels and the blood vessels, the cancerous cells traveling at a high speed through the bloodstream and the lymph fluid until they reach far distanced tissues and organs and develop secondary and small tumors.

The testicle produce almost ninety percent of the body’s hormones, the other ten percent of testosterone being made by the adrenal glands, located near the kidneys.

Testosterone is responsible for fueling the growth of any prostatic cell without making a difference between cancerous tissues and healthy tissues; the hormone therapy removes the chemical responsible with the feeding of those cells.

The part of the brain called hypothalamus is responsible with the monitoring of the levels of testosterone, and when that level drops the hypothalamus releases two chemicals: the GnRH or the gonadotropin releasing hormone that stimulates the production of the hormone in the testicles or the LHRH or the luteinizing hormone releasing hormone.

The free testosterone refers to the amount or the level of testosterone found in the bloodstream that is not bound to any other chemicals such as globulin or albumin.

The levels of free testosterone are usually measured by blood tests and they indicate if a person’s hormones are functioning normally. To detect any hormonal unbalance, the tests for free testosterone are recommended to both men and women.

An indirect way to measure the level of the sex hormone biding globulin or SHBG in the bloodstream is by measuring the levels of free testosterone. Low levels of SHBG are responsible for obesity or the reduction in thyroid performance while high levels of SHBG indicate estrogen use, hyperthyroidism and cirrhosis.

The free testosterone may also be responsible for the lack of energy, mood problems or for a decreased libido.

When health or hormonal problems affect the life of a patient it is necessary to measure the level of the free testosterone, and if abnormal levels are detected doctors usually prescribe testosterone injections to increase the energy and improve the memory or supplemental testosterone.
