Dr. David Samadi Discusses Links Among Testosterone And Prostate Cancer

For many men, testosterone is the key to virility, but in a Fox News segment, expert oncology urologist, Dr. David Samadi say it could increase the risk for prostate cancer. It may be as simple as taking medications to lower testosterone levels, but doctors say that could cause other problems.

In order for the prostate gland to grow correctly, testosterone is required, however, high levels of the hormone are linked to cancerous growths. The obvious idea of lowering testosterone levels with medication and thus eliminating the risk of cancer is unfortunately not as uncomplicated as it sounds. Although there are drugs that lower testosterone levels (finasteride). These are used, for example, in the treatment of prostatic hyperplasia (benign enlarged prostate gland), which also involves a reduction in the effect of testosterone.

However, current expert opinions say these preparations are not yet considered for long-term cancer prevention. Expert urologist, Dr. David Samadi points out the prolonged loss of testosterone can also lead to erectile dysfunction, declining sexual desire and breast growth. Here then benefit and risk would be in a disproportionate relationship, because most men that are treated would never get prostate cancer, even without medication.

Testosterone levels in men begin to decline after age forty. This decrease causes the appearance of numerous symptoms including depression , sexual dysfunction , impotence, loss of muscle mass and strength and decreased bone density. Many doctors prescribe hormone therapy but have found that testosterone supplementation has increased the risks for prostate cancer.

However, during the studies, it was found that during peak testosterone levels, in young men, there were no incidences of prostate cancer. As Dr. David Samadi points out, there are many men who take testosterone supplements for bodybuilding, and they should be aware of these links to prostate cancer.

With more than 20 years of experience, Dr. David Samadi is an international expert in many facets of urology,with a focus on minimally invasive robotic prostate cancer. He serves as the Chairman of Urology at Lenox Hill Hospital, as well as Chief of Robotic Surgery. He has changed the field of laparoscopic prostatectomy with his innovative Samadi Modified Advanced Robotic (SMART) surgery technique. The technique is a modification to the traditional prostate surgery, where he is able to safeguard neurovascular bundles while operating on the prostate gland. Dr. Samadi’s minimally invasive technique has resulted in less time in the operating room and the patient’s faster recovery.
