Prostate cancer is a disease that develops over many years in the prostate of people. Over time, information about prostate cancer showed that the cancer spread from the prostate to other tissues, including lymph nodes, bone, liver and lungs. The first symptoms of prostate cancer usually painful urination, difficulty urinating, and erectile dysfunction.
Prostate cancer responds well to many forms of traditional cancer therapies, including surgery and radiation. Because prostate cancer grows very slowly, the initial stages are not treated generally monitored. Additional treatments such as cryosurgery, hormonal therapy and chemotherapy are also available. These alternative treatments are usually reserved for late stage prostate cancer and not established as a first-line treatment.
Prostate cancer is usually obvious symptoms. However, some patients, frequent urination, day and night, difficulty urinating or begin a steady flow, or blood in the urine have received. It is estimated that only one-third of patients with prostate cancer experience no symptoms in the early stages.
According to the available information about prostate cancer, age, family history, and obesity are risk factors. Prostate cancer is diagnosed in patients under 45 years, with a mean age of diagnosis at 70 years. It is believed that the inheritance is currently the most well-known risk factor for the development of prostate cancer. Scientists have shown that men with a father or brother (first degree), who was diagnosed with prostate cancer have twice the risk of developing the disease and those who have two or more first-degree relatives with the disease who have a five times higher risk.
The most important part of a diagnosis of prostate cancer is the classification or the stage of the disease. There are four recognized levels. This includes:
- Stage I: Cancer cells are found only in the prostate. The tumor can not be detected by digital rectal examination, and not be seen on a diagnostic test for images.
- Stage II: Cancer cells are found only in the prostate. The tumor began to grow in size. You may or may not digital rectal examination, however, be recognized; can make the image when the diagnostic test point.
- Stage III: Cancer cells have begun to invade the surrounding tissue. In this phase, the signs of the seminal vesicle invasion of cancer cells to show; However, the pelvic lymph nodes are clear. The tumor can be identified by digital rectal examination.
- Stage IV: Cancer cells have metastases in other tissues, including lymph nodes, lungs, liver and bones.
Screening for prostate cancer is an important part of the treatment of prostate cancer. The earlier cancer is detected; Treatment planning and administration of the first can be found. For 50-year-old man with a family history should discuss screening for prostate cancer with their doctors. Currently, the test is complete only conformational a biopsy. However, other methods for screening include the digital rectal examination, imaging of the prostate, and tests for tumor markers
