Cancer comes a-calling (well not always!)

My knowledge is limited – but here goes, with an emphasis on male prostate cancer:
Cancers may be influenced by several factors:
1. External i.e. smoking or obesity.
2. Internal - Genetic make-up, if your relatives had a certain type of cancer then you may (or not) have a higher chance of developing cancer (or other medical issues) but it's not straightforward as mutations (some of them cancer-causing) are not always passed on directly.
Two common types of cancer (breast and prostate) feed and grow as a result of male and female hormones - Oestrogen and Testosterone, respectively.
There is more than one type of prostate cancer, some are slow-growing whereas others are very aggressive and strike quickly,
Because cancer of the bowel/colon is relatively common and straightforward to test and diagnose prevention schemes are being run using the 'blood in the poo' test to analyse signs of potential cancer.
Prostate cancer is a little more difficult as the 'PSA' test, done by taking a simple blood sample, is a broad-brush approach and not terribly reliable. Low scores being reassuring but high numbers are a cause for greater concern.
The only current, better test, is by the old digital rectal examination (DRE) 'finger in the bottom' performed by the GP (who is generally less experienced and probably dislikes the procedure as much as the patient) or a consultant at hospital who is much more experienced and so can make a more accurate diagnosis.
Different examinations by medics with various experience may result in results that are not always in agreement.
Men do not like going to the GP at the best of times and to have a 'finger in the bottom' test is so invasive and unnatural that it prevents many from seeking help until the cancer or non-cancerous but swollen prostate, presents much more serious symptoms.
As far as I understand the prostate sits below the bladder and has biological connections with the urethra which then passes urine from the bladder to the outside world.
Any problems with passing water (peeing) or flow rate may, or may not, be causes for concern.
Clearly if men experience issues with passing water then they should see their GP and rule out prostate issues of any kind.
Sometimes the prostate is just enlarged with age and needs surgical reduction in order to be able to relieve oneself normally - at full flow rate!
If prostate cancer is eventually diagnosed and according to type and whether it has spread outside the 'capsule' of the prostate, there are then several options, removal of the prostate with the risk of damaging nearby nerves which control the ability to 'perform' or by zapping the cancer with radioactive isotopes over a number of weeks.
If the cancer has spread out beyond the prostate, (by metastasis) typically seeking routes via the bone-marrow, then we are into more difficult waters.
Men are not subject to regular screening for prostate cancer but women have tests for cervical and breast cancers and early detection, as with all cancers, is the key.
We are encouraged to do our bit by not doing anything that may encourage the 'external' cancers, such as those influenced / provoked by smoking, excessive lifestyle etcetera.
