Being told that you have prostate cancer can be a frightening experience. When you are told of your condition, it's common to be so overwhelmed that you neglect to ask important questions, only to think of them once you've gotten home. Understanding your illness is often the first step on the road to recovery. Here's what you need to know about your diagnosis and how the cancer is staged:

1.Diagnosing Stages

Once a man has been diagnosed with prostate cancer, his physician will perform one or more additional tests to determine the stage of cancer. These tests may include a digital rectal examination, a blood test, an MRI of the prostate or skeleton, a CT of the pelvis and abdomen, or a surgical procedure to examine lymph nodes. While not all men will need each test, most men will undergo at least one of these tests in order for their physician to better stage the cancer.

2.Stage I

If you are diagnosed with stage I prostate cancer, this means that your cancer is microscopic and only located in the prostate. Your cancer will not be large enough for your doctor to manipulate digitally. Additionally, the cancer will not be able to be detected on any digital imaging of the prostate gland. Stage I cancer of the prostate will be discovered by a needle biopsy or in tissue that is removed during other surgical procedures.

3.Stage II

In stage II prostate cancer, the cancer is still located solely in the prostate. The cancer may be found in one-half or less of one lobe of the prostate, in more than one-half of one lobe or in opposite sides of the prostate gland. As in stage I prostate cancer, stage II cancers cannot be felt during digital rectal exams, nor will the cancer be visible on any type of imaging.

4.Stage III

In stage III prostate cancer, the cancer has spread outside of the prostate to nearby tissues. The prostate specific antigen, or PSA, score can be at any level and the Gleason score will range between two and ten. Your doctor may choose to treat you with external-beam radiation therapy, hormone therapy or suggest you for a clinical trial of new therapies. Alternatively, your doctor may suggest no treatment at all and, instead, adopt a watch and see approach to your cancer.

5.Stage IV

When your prostate cancer has metastasized, or spread, to other areas of your body, you are diagnosed with stage IV cancer. Your cancer may be found in your bones, liver, lungs or lymph nodes. Stage IV prostate cancer, like other cancers that have reached the fourth stage, is considered to be the most serious. Without immediate treatment, this type of cancer will likely prove fatal. Your doctor may prescribe chemotherapy, radiation therapy, hormone therapy or a radical prostatectomy combined with other therapies.

The better you understand your diagnosis and the stage of prostate cancer that has been discovered, the better equipped you will be to partner with your oncologist to aggressively tackle your disease. If you have been diagnosed with prostate cancer, do not hesitate to approach your doctor with any questions that you may have. Your gained knowledge may just save your life.

Adipose tissue surrounding the prostate gland of men with obesity, creates favorable conditions for the progression of prostate cancer.

What is the prostate gland
The prostate gland - is musculo-glandular organ located below the bladder and surrounding the initial portion of the urethra. The main function of the prostate is to produce secretions, which is part of semen. Ducts of the prostate glands open into the urethra.

Prostate cancer
In the early stages of prostate cancer does not manifest itself. Complaints are associated with tumor spread and metastasis. At the stage the only manifestation of the lack of symptoms, allowing the disease to suspect, is to increase blood levels of prostate specific antigen (PSA). As prevention of prostate cancer for all men should conduct an annual PSA test beginning at age 45.

By increasing the size of the tumor shows the following symptoms:
  • Frequent urination
  • Difficulty urinating
  • Urinary incontinence
  • urge to urinate.
The essence of the study

Scientists have received samples of adipose tissue surrounding the prostate gland in men with benign prostatic hyperplasia, prostate cancer and prostate cancer. Regardless of prostate disease in men with obesity , there is increased activity of genes in fat cells. These genes encode proteins involved in the immune response, inflammation, growth, reproduction, and cell death.

Increase in the activity of genes leads to inhibition of the immune response and stimulates the formation of new blood vessels, which creates favorable conditions for the progression of prostate cancer. The study's authors hope that the findings will more carefully selected treatments for patients with obesity.

High levels of the hormone that regulates sleep-wake cycles - melatonin - reduces the risk of developing aggressive prostate cancer at 75%, has established a group of researchers of the department of epidemiology at the Harvard School of Public Health (Boston).

The results of the scientists were presented at the conference of cancer, according to Medical Xpress .

Melatonin is produced exclusively in the dark and is an important regulatory component of human circadian rhythms. "Insomnia and other sleep disorders can affect the amount of melatonin or completely stop its production in the body," - explained Sara Markt (Sarah Markt), one of the co-operation.

The study, which lasted for seven years, attended 928 Icelandic men. Volunteers were asked to answer questions related to the regime of sleep and wakefulness, as well as urine test, in which scientists determined the level of one of the decay products of melatonin.

It turned out that every eight volunteers had trouble falling asleep, one in five could not sleep for a long time (all the time waking up), and one-third took sleeping pills. All these men melatonin level was significantly lower than that volunteers do not have problems with sleep. Of 928 participants with prostate cancer developed in 111.

The researchers found that men with high levels of melatonin had a 75% lower risk of aggressive cancer. Now Markt and her colleagues plan to confirm this result in further studies.

Canadian scientists have proposed to diagnose prostate cancer with the help of another hormone - ghrelin is responsible for hunger.

In early stage of Prostate Cancer, there's no special clinical manifestation, whereas as time goes by, Prostate Cancer shall manifest several varieties of symptoms and these symptoms would exacerbate step by step. To sum up, there area unit in the main 3 aspects as follows:

Symptoms of Prostate Cancer

Urination obstruction: as a result of the tumor's volume will increase step by step therefore on squeeze duct, therefore patients with Prostate Cancercan suffer from more and more getting-worse symptoms like upset, frequent voiding or voiding urgency, or different stimulation symptoms like odynuria. a part of advanced stage Prostate Cancer patients would suffer from retention as a result of they're utterly unable to urinate.

Other tissues to be concerned in: once Prostate Cancer invades adjacent or encircled tissues or organs, a series of native infiltration symptoms shall be caused, for instance, neoplasm offensive nerve and cavitas pelvis would cause pain in lower abdomen likewise as in area or perhaps in male reproductive gland, or bearing-down pain in pocket or lumgago; neoplasm offensive vesica, vesicle, would cause these symptoms like bloody voiding, hemospemia; neoplasm offensive canal would cause hydronephrosis; if duct is invaded, corresponding symptoms like piddle retention or enuresis then on area unit caused.

Tumor metastasis: it's simple for Prostate Cancer to unfold to skeleton, before skeleton being destroyed, Prostate Cancer patients shall suffer from nice pain, and meantime bear the additional risk of bone fracture. If bone marrow is broken, the immunity degrade or anaemia would appear; neoplasm spreading to blood vessels or lymph gland close, circulation of blood or humor fluid would be blocked or blocked so the limbs or area of patients shall suffer from edema; neoplasm spreading to respiratory organ, would cause hurting, pulmonic infection, respiration problem, ejection blood then on; neoplasm spreading to liver, would cause discomforts to liver space, jaundice then on; neoplasm spreading to brain, would cause headache, dizziness, vomiting, cognitive state then on; advanced stage Prostate Cancer patients could suffer from serosa fluid, ascites, swollen everywhere the body then on.
