Prostate cancer is a typical male disease and is the second most common adult male cancer in the United States, after skin cancer.
In the case of prostate cancer, the American Cancer Society estimates that there will be about 161,360 new cases and about 26,730 adult males will die of the impact of prostate cancer in the United States by 2017.
Like cancer in other areas of the body, some dangerous prostate cancers develop and spread rapidly, most developing slowly.
Levels 1 through 4 are just some of the complex systems doctors can use to summarize cancer.
Cancerous doctors and men refer to this level of 1, 2, 3, or 4 diseases. These levels are only part of a very complicated system used to classify cancers and how dangerous developments are in their spread.
The tumor is examined well during the procedure is transurethral resection of the prostate (TURP), which is used to treat abnormal prostate development, or during needle biopsy. Needle biopsy is a test used to investigate the development of prostate-specific antigen (PSA).
There are three different parts of tumor T1, classified according to how the cancer is found
- T1a: found during TURP, cancer is present in 5 percent, or less of tissue that can be excreted
- T1b: found during TURP, cancer is present in more than 5 percent of tissue that can be removed
- T1c: detection during needle biopsy
These tumors can be larger than T1 tumors and are divided into three types according to their size and location:
• T2a: present in one half or less of one side of the prostate• T2b: is in more than one half of one side of the prostate• T2c: present on both sides of the prostateTumor T3This tumor grows outside the prostate.Tumor T4This tumor has grown into the tissue outside of the prostate.N indicates if the cancer has spread to the lymph nodes while M shows not spread, in other parts of the body. The system shows depends on two other important factors. This is the level of PSA in the blood at the time of diagnosis and Gleason score.PSA is that proteins can appear at higher levels in the bloodstream when there is a problem with the prostate. The Gleason score shows how cancer cells exist and how likely they can spread.Both components are determined either by biopsy or surgery.Stages 1Level 1 prostate cancer is small and growing slowly. A person who has prostate cancer and is not detected except by examination by a doctor.Gleason score and PSA level is low. Someone may not feel the symptoms or other health problems.Stage 2 Unlike normal prostate cancer level 1, doctors can characterize level 2 prostate cancer during a physical exam.Cancer level 2 is also in the prostate but can be felt by doctors because of someone who has cancer in stage 1. They have higher Gleason score or higher PSA level, or both from cancer level 1.There are two parts of prostate cancer level 2, which is known by the size and location of the tumor: The two parts are 2a and 2b.Prostate cancer known as 2a can be a T1 tumor with a higher PSA or Gleason score, or T2a or T2b with a lower PSA or Gleason score.Prostate cancer known as 2b can be a T2c tumor, or a T2a or T2b tumor with a very high PSA or Gleason score.Level 3Level 3 cancers have progressed more rapidly than the prostate. They may have reached the seminal vesicles but not about the bladder or rectum. Seminal vesicles are glands that secrete fluid that can help form semen.Cancer that has progressed to this level is more likely to return after treatment.Level 4Cancer level 4 is the most serious because it can spread more widely to other areas of organs. While some may be curable, most cancers of 4 cannot be cured, the goal of treatment is to control the cancer as long as possible and to improve one’s quality of life.
