Prostate cancer is a malevolent cancer that consists of cells from the prostate gland. Normally, the tumor grows gradually and remains limited to the gland for several years. All through this time, the tumor produces little or no symptoms or external signs though; all prostate cancers do not act similarly. Some insistent types of prostate cancer nurture and multiply more quickly than others and can cause a considerable shortening of life expectancy in men affected by them. This cancer is divided into many stages and hence one should be cautious about it and should visit a doctor if any of the symptoms is visible as early detection would enable one to treat it with efficiency.

Several kinds of prostate cancer include:

  • Adenocarcinoma.

    The most common type of prostate cancer is adenocarcinoma. This cancer is generally slow growing, but still has the potential to spread beyond the prostate to other areas, including lymph nodes, bones and other organs.

  • Small cell carcinoma.

    This rare, aggressive prostate cancer initially forms in specialized cells within the prostate. This type of cancer generally doesn’t increase prostate-specific antigen (PSA) levels and is harder to detect in its early stages. More advanced cases of small cell carcinoma can be difficult to treat.

  • Rarer prostate cancer.

    There are also other, rarer types of prostate cancer.

The root cause of prostate cancer is mysterious, but the cancer is not considered to be linked to benign prostatic hyperplasia. The threat factors for prostate cancer take in advancing age, inheritance, hormonal influences, and ecological factors as toxins, chemicals, and industrial products. The chances of developing prostate cancer amplify with age. Thus, prostate cancer under age 40 is exceptionally rare, while it is general in men older than 80 years of age. In the early stages, prostate tumor often causes no symptoms for a number of years. As a matter of fact, these cancers recurrently are first identified by an aberration on a blood test or as a hard lump in the prostate gland. Sporadically, the doctor may first feel a hard nodule during a regular digital rectal test. The prostate gland is to be found immediately in front of the rectum.

Prostate cancer is diagnosed from the results of a biopsy of the prostate gland. If the digital rectal examination of the prostate or the PSA blood test is atypical, a prostate tumor is assumed. A biopsy of the prostate is then frequently suggested.
