How does prostate cancer kill a patient?

What is Cancer? Cancer is the uncontrolled growth of a part of the body, with the potential for spread locally or to distant locations, causing dysfunction or organ failure and, ultimately, death. Any cancer increases the risk for blood clots, which can flow to the lungs and kill a patient (pulmonary embolism). Cancers tend to deprive a patient of nutrients, damaging the immune system, increasing infection risk.
Different effects. Prostate cancer, like most cancers, kill patients by varoius methods. Specifically for prostate cancer, a leading cause of mortality is bone metstasis which typically leads to fractures and possible surgery. Other causes inlcude, bleeding, kidney failure from urinary obstruction, and malnutrition.

Not low risk. Stage 3 prostate cancer should be addressed, unless your father has no symptoms from this and has a limited life expectancy from another medical condition. People are often mistaken by thinking NO MEN die from prostate cancer, but ~30, 000 per year do die from it. Low risk prostate cancer often can be observed and not treated, but this is not true for stage 3 prostate cancer.

While MOST 81 yo won't require treatment if they have LOW RISK cancer ; if they have high risk and hey are very healthy treatment of some kind may prolong the Pts life and can be done in a way NOT to impact life quality!

Why is prostate cancer screening so controversial? Its relatively common in older men, so shouldnt older men be checked before it can spread and kill?

Screening is hard. Prostate cancer screening is actually difficult, currently we don't have a really good test that reliably tells us if a man has prostate cancer. The PSA (prostate specific antigen) test used for cancer can go up and down and not always be due to prostate cancer. When we do prostate checks by digital rectal exam that can cause the PSA to go up. Many men have prostate enlargement and not cancer.

For a prostate cancer patient, can he start lhrh treatment first to see the effect, then go for orchirectomy? Any drawback to do this?

Yes, you can do it. No drawback. Absolutely he can start with lhrh agonist like Lupron (leuprolide) plus minus Casodex for instance and reserve the option of orchiectomy for the future-if needed. That's what we usually do actually most of the time. No drawback with that plan. Discuss with your doctor in detail.
No drawback. This is the preferred approach for the majority of patients.
No. There is no drawback. The effect would be similar either way, but lhrh injection would allow for intermittent therapy if appropriate. If permanent hormone deprivation is desired, orchiectomy can be performed at a later time.
Orchiectomy is the. Least costly way to treat advanced prosca. Lhrh shots are expensie, but can be stopped, and there is a chance that testicular function can be resumed...Not usually necessary in advanced disease, but a desireable feture for short course testicular blockade in intermediate risk disease.
