6. Is it possible to be screened for prostate cancer?

Yes, although current screening is not foolproof. The two most commonly used screening test will indicate the possibility of a developing problem, which may or may not be cancer, and point to the need for further more specific testing.

The tests currently in use are the digital rectal exam (DRE), in which a doctor carries out an investigation of the prostate gland by feeling it with a gloved finger inserted through the rectum to detect the presence of hard or lumpy areas, and a blood test used to detect the presence of a substance which is known as prostate specific antigen (PSA) and which is made by the prostate gland.

7. How reliable are present screening methods?

Neither of the current screening tests is foolproof and both can easily miss prostate cancers. However, the two tests used together can produce quite reasonable results and are certainly preferable to not screening for the condition at all. Research is currently underway to find a more accurate method of screening.

8. How is a diagnosis of prostate cancer made?

There is really only one way to confirm the presence of prostate cancer and this is by carrying out a prostate biopsy. This involves removing a number of small samples of tissue from various different parts of the prostate gland and examining these under a microscope in the laboratory.

9. How is prostate cancer treated?

If prostate cancer is localized (that is to say confined only to the prostate gland) there are at present three main forms of treatment available.

One option is to do nothing and to simply watch and wait. If this seems an odd course of action it should be borne in mind that many prostate cancers appear at a very advanced age and, as long as the cancer remains within the prostate gland and is slow growing, the best option for an elderly patient might well be to do nothing at all.

Where active treatment is carried out this will often be to either treat the prostate gland with radiation to kill the cancer cells or to simply remove the prostate gland surgically.

In cases where cancer has spread outside of the prostate gland there are a wide range of treatment options available depending on the degree of spread. This is however a complex area and beyond the scope of this short article.

10. What is the best treatment for localized prostate cancer?

This is a bit like asking ‘how long is a piece of string’ as there are a large number of factors which need to be taken into consideration, not the least of which are the patient’s own circumstances and wishes.

In the majority of cases however prostate cancer is slow growing and there is usually no need to rush into a treatment plan. This gives patients time to discuss their condition with their doctor, including taking a second or even third opinion if they wish, and also to discuss matters with their partner and family before making any decision.
