Adjuvant radiotherapy – Radiotherapy offered immediately after surgery if the cancer is aggressive or at high risk of recurrence.
(See Mr PHIP No. 4)
Adrenal glands – Small glands lying on top of the kidneys which produce a small amount of male hormone.
Anaesthetic – A medication used to relieve pain and reduce feeling during surgery. An anaesthetic can be:
Local – when you lose feeling to the part of your body where the medication is injected, but you remain awake. Eg. a needle prior to having dental work;
Spinal – anaesthetic medication is injected into the spinal canal and you lose all feeling from your waist down; or
General – administered for more major procedures where you lose consciousness and wake up when the procedure is over.
Androgens – Male hormones. The most active male hormone, testosterone, is produced by the testicles. Other male hormones are produced by the adrenal glands. (See Mr PHIP No. 5)
Anti-androgens – Drugs which block the effects of male hormones. (See Mr PHIP No. 5)
Asymptomatic – Not having symptoms, symptom-free.
Benign – Non-cancerous (not cancer).
Benign prostatic hyperplasia (BPH) – A condition causing non-cancerous enlargement of the prostate. (See Mr PHIP No. 2)

Bisphosphonates – Drugs that improve bone strength in men with prostate cancer that has spread to the bone. They may also be recommended for patients on hormone (androgen deprivation) treatment, which weakens the bones. A common one is zoledronic acid.
Bone Scan – A type of X-ray used to locate cancerous activity in bones. A low-dose radioactive chemical is injected into a vein and the X-rays trace its location in the body. The chemical becomes focused in parts of the bones that are abnormal, such as areas of cancer and the X-ray images identify these as ‘hot spots’.
BPH – Benign Prostatic Hyperplasia. A condition causing non-cancerous enlargement of the prostate.
Brachytherapy – A type of prostate radiotherapy – involves the insertion of radioactive seeds or rods directly into the prostate. (See Mr PHIP No. 3)

Digital Rectal Examination (DRE) – An examination of the prostate through the rectum. The doctor places a gloved finger in the rectum and feels the shape of the prostate. Cancer may cause irregularities.
Dry ejaculation – Also called reverse or retrograde ejaculation. After surgery on the prostate, a man may achieve orgasm, but produce no ejaculate. This is because of either the removal of a muscular valve which prevents the ejaculate from going backwards into the bladder (in the case of surgery called a TURP), or because the glands which produce much of the fluid in the ejaculate are also removed (in the case of a radical prostatectomy).
Ejaculate – Fluid produced at ejaculation which contains sperm and secretions from glands such as the prostate, seminal vesicles and testicles.
Epididymis – A long tube that lies on top of each testicle and functions as a reservoir for sperm produced by the testes.

External Beam Radiotherapy (EBR) – A form of radiotherapy where the prostate is targeted with high-energy X-rays from therapy outside the body.
Focal therapy – The removal or ‘ablation’ of small areas of cancer within the prostate gland. (See Mr PHIP No. 3)
Free to total PSA ratio – In both healthy men and those with prostate cancer, the prostate specific antigen (PSA) in the bloodstream ‘binds’ onto protein. In men with benign prostatic enlargement (BPE), there tends to be more ‘free’ or ‘unbound’ PSA. This test compares the ratio of unbound PSA to total PSA in the bloodstream. A low result is more likely to indicate cancer. (See Mr PHIP No. 2)
Grade – A way of describing how abnormal the cancer cells look, and consequently how aggressive or fast-growing the cancer is likely to be. The most commonly used grading system is the Gleason score, which ranges from 2-10. (See Mr PHIP No. 3 and 4)
High intensity focused ultrasound (HIFU) – Heating of tissue using microwaves.
(See Mr PHIP No. 3)
Hormone resistance – Prostate cancer cells are dependent on testosterone or male hormone for growth. Withdrawal of male hormone by surgery or by means of drugs is therefore a means of controlling its growth. However cancer cells may develop which do not need testosterone for growth. The cancer is then said to be ‘resistant’ to hormone treatment. (See Mr PHIP No. 3)
Hormone treatment – In prostate cancer, treatment with drugs that blocks the production or effects of testosterone in the body in order to slow or stop the growth of prostate cancer. (See Mr PHIP No. 3 and 5)

Image-guided radiotherapy – A common technique used to assist radiation targeting and involves placing three (non-radioactive) seeds into the prostate before treatment. This means the doctor can better monitor the position of the prostate during the course of radiation. (See Mr PHIP No. 3)
Impotence – Inability to achieve an erection.
Incontinence – Inability to hold urine or control urine loss.
Indolent – Means “lazy”, usually referring to the type of cancer cells which grow only slowly.

Intermittent hormone therapy – Hormone treatment that is started and stopped in cycles. Typically, it is continued for several months until PSA has reached a low level, and then discontinued. Once the PSA level in blood rises to a particular level again (and this can take many months), hormone treatment is restarted. The main expected benefit in this approach is reduction in side effects. (See Mr PHIP No. 3 and 5)
Intermittent therapy – A non-continuous form of hormone treatment for prostate cancer, where treatment starts and stops repeatedly. Its aim is to minimise the effects of hormone therapy. (See Mr PHIP No. 3 and 5)
