How does a black man receive professional urological medical treatment? Keep your filthy misandristic sadistic racist females away from us. . It amazes me that you turn our genitals over to your female accomplices to abuse us as they wis.h.

How about treating our disease rather than making us androgynous? Give us treatments to retain our masculinity and stop turning us over to your your female accomplices to abuse as you and they wish,.

Treatments for prostate cancer
Is removal and/or radiation better for small, slow growing, tumors in prostate?

I made the decision to have my proste removed and it was not an easy time... just as hard as finding out you had prostate cancer... I was advised by my doctors the surgery was the best option because of my age and the harmful affects of radiation longterm. For me, once I made the decision, I did have the peace of mind knowing that the actual cancer was "removed" instead of just treated... which, I guess, did give me some sense of comfort.
The biggest issue for me once the surgery was done and I was on the road to recovering was the effects it had on me emotionally/psychologically, which many people in my opinion overlook. I encourage anyone and everyone, when diagnosed with prostate cancer, before and after treatment and during, to seek psychological help... there is nothing wrong with it. Medications, counseling, and just talking about your feelings can help tremendously. Do not hold it all in and try to battle the anxiety and depression because this diagnosis will affect you, no matter how strong you may consider yourself to be.
The sexual effects treatment has on you will also affect you mentally, because your sexual ability and ability to have kids will likely be affected. Your performance ability can be likely fixed, but it can still affect you mentaly. Take care of yourself.

Hormone therapy for prostate cancer does not always work; the tumor can become resistant and continue to spread. Now, new research reveals how the therapy alters the environment of tumor cells to make this happen.
Scientists at the Cedars-Sinai Medical Center in Los Angeles, CA, suggest that their study could lead to a "simple blood test" to identify prostate cancer cases that are likely to become resistant and aggressive if they are treated with hormone therapy.
They report their findings in a study paper that now features in the Journal of Clinical Investigation.
Prostate cancer starts in the prostate, which is a gland that lies between a man's bladder and his penis, next to the rectum. The gland surrounds the urethra, which is the tube that carries urine from the bladder to the penis. It makes and adds fluid to semen as it passes through this tube.
The cancer begins when cells in the prostate grow out of control and form a tumor. It arises mostly in men aged 65 and older and rarely before the age of 40.In the United States, prostate cancer is the most common cancer in men after skin cancer. The American Cancer Society (ACS) estimate that the U.S. will see around 164,690 new cases of prostate cancer and 29,430 deaths to the disease in 2018.
Hormone Therapy For Prostate Cancer
Although it can be serious, most men diagnosed with prostate cancer will not die of it. This is why today in the U.S., there are 2.9 million men living with or who have survived the disease.
In general, prostate cancer survival rates are higher the earlier the cancer is detected and treated. However, many other factors can also affect a man's outlook, including how well his cancer reacts to treatment.
The male sex hormone androgen stimulates tumor growth in prostate cancer. Hormone therapy, also known as androgen deprivation or androgen-targeting therapy aims to halt tumor growth by reducing androgen levels or by blocking its effect on tumor cells.
The treatment can be used, for example, to shrink tumors before radiation therapy, or to treat men in whom surgery or radiation therapy has been ruled out.
Hormone therapy can be successful, but there are cases when the tumor develops resistance to the treatment and then comes back or spreads.
Transforms Cancer Into More Aggressive Type
In their study paper, the Cedars-Sinai researchers reveal that a possible reason for this is that the hormone therapy triggers a fundamental change in the tumor.
It causes some cancer cells, which are mainly of the common adenocarcinoma type, to transform into a much rarer type called neuroendocrine, which occurs in less than 1 percent of cases.
"This transformation is a problem," says senior study author Neil A. Bhowmick, who is the co-director of the Cancer Biology Program at Cedars-Sinai, "because neuroendocrine prostate cancer is especially aggressive, metastasizes more readily, and is more resistant to both androgen-targeted therapy and chemotherapy."
He explains that there is evidence to suggest that around a quarter of men treated with hormone therapy can experience a return of their cancer in which the tumors look like neuroendocrine prostate cancer and become treatment resistant.
So, working mainly with mice, he and his colleagues decided to focus on the interaction between prostate cancer cells and their microenvironment inside the tumor. The microenvironment is supported by cells called stromal cells.
The team found that androgen deprivation therapy can influence genetic programs in the stromal cells to cause prostate cancer to progress to "a more aggressive differentiation state."
Rise In Glutamine
They also observed that the cell transformation was accompanied by a rise in glutamine, an amino acid that is known to hasten the growth of cancer.
The glutamine was being produced in the genetically altered stromal cells and "served as a source of energy" for the cancer cells, as well as helping transform the adenocarcinoma cells into neuroendocrine ones.
Finally, the scientists confirmed the glutamine finding in humans. In a small group of men who had prostate cancer, they found that those whose cancer was resistant to treatment had higher levels of glutamine in their blood than those whose cancer responded to treatment.
They suggest that this means that it should be possible to develop a simple blood test to detect those prostate cancers that are not responding to hormone therapy and perhaps even predict resistance.
"To our surprise, we found this type of therapy further changed the cellular environment in a way that caused adenocarcinoma cells in the prostate to transform into neuroendocrine cancer-type cells[,]" [stated] Neil A. Bhowmick.
