Side effects of treatments: Lack of energy
Many men with prostate cancer feel tired from time to time. One cause can be interrupted sleep when a man has to pass urine frequently during the night. However, radiotherapy and hormone treatment are known to affect energy*. Expectations differ; some men reported that their sporting activities had become limited and others regretted that they lacked the energy to work or tackle household and garden chores. One man, who had a radical prostatectomy in 1993, also said that the operation had reduced his stamina and greatly affected his lifestyle.
*Newer hormone therapies such as bicalutamide (Casodex) are suitable for non-metastatic disease and it does not lower testosterone so patients should not become as lethargic or fatigued (for more information on Casodex see Macmillan Cancer Support).
