Prostate cancer is one of the most common types of cancer in men. Typically, it grows slowly and remains confined to the prostate gland, but there are other types of prostate cancer that are aggressive and spread quickly to the bones and other organs, according to the Mayo Clinic.
Experts have speculated that the intense vibrations from machinery cause the body to produce more testosterone. This hormone fuels the cancer cells and helps them grow. With excess testosterone in the body, the risk for getting prostate cancer can increase.
For the study, the National Cancer Institute analyzed over 2,000 men with prostate cancer. The men were asked which two jobs were the longest of their careers, and which job they had upon diagnosis.
The men who were truck drivers were four times more likely to be diagnosed with the aggressive form of prostate cancer than men with other careers. Educators were used as the baseline comparison group.
While testosterone is said to be a risk factor, there isn’t even data to draw a direct conclusion between truck driving and the aggressive form of prostate cancer. There may also be a link to diet and a sedentary lifestyle that contributes to the cancer.
Other risk factors for prostate cancer include:
• Older age (over 65)
• African American
• Family history of prostate cancer
There is no standard or routine test for prostate cancer. Doctors may utilize a digital rectal exam (DRE) to detect a hardened mass in the prostate, or they may perform a test that measures the amount of prostate-specific antigen (PSA) in your blood. Increased PSA is typically found in the blood of men who have prostate cancer, but there are other reasons why your PSA may be elevated.
For now, while other tests are being studied, doctors are recommending a combination of the PSA test and the DRE as an accurate screening tool for prostate cancer. Men between the ages of 40 and 75 are generally encouraged to get these tests.
