I'm Dr. Humphreys, a urologist at Mayo Clinic. In this video, we'll cover the basics of prostate cancer: What is it? Who gets it? The symptoms, diagnosis, and treatment. Whether you're looking for answers about your own health or that of someone you love, we're here to provide you with the best information available. Prostate cancer, unfortunately, is common.
It affects one in seven men, making it the second most common cancer among men worldwide. The good news is, is that prostate cancer can be curable, especially when identified and treated early. That is why I and most urologists and medical professionals you talk to encourage men over a certain age to get regular prostate screenings. First, let's talk about what the prostate is and how it functions. The prostate is a small gland that is involved in reproduction and makes some of the essential components in semen.
While it is small, it has an important role in reproductive health and can cause voiding or urinary symptoms as men age, as well becoming a source of cancer. Like other kinds of cancer, prostate cancer starts when cells mutate.
These small changes in DNA cause the cells to grow faster and live longer than they normally would. As these abnormal cells accumulate, they monopolize resources from normal cells, which can damage surrounding tissue. These cancerous cells can then spread to other parts of the body. By definition, prostate cancer only affects bodies with male reproductive organs.
But in addition, there are some other risk factors that we can monitor. Age is a big one, as prostate cancer is more prevalent in older men, which is why testing is encouraged as men age. For reasons that are unclear, Black men also have a greater risk compared to other races or ethnicities.
