Radiotherapy after surgery for prostate cancer

Surgical removal of the prostate has a high chance of cure when prostate cancer is confined to the prostate. High‐risk features (ie, cancer that has spread through the capsule surrounding the prostate into the nearby seminal vesicles or to the edge of the surgical specimen) found at the time of surgery increase the risk of the cancer recurring. Recurrence of cancer might show up as an abnormal blood test (increased prostate‐specific antigen (PSA)), local recurrence at the site of the prostate, or distant spread (most commonly to bones).

How does the thyroid work?

The thyroid is a vitally important hormonal gland that regulates metabolism and growth in the body. The thyroid hormones T3 and T4 increase the basal metabolic rate. In other words, they make the body cells work harder, using more energy. If more energy is needed for metabolic processes in the body – for instance for growth, when it is cold, or during pregnancy – more hormones are produced and transported into the blood.
