Who Gets Prostate Cancer
Prostate cancer develops mostly in older men.1 It is extremely rare for it to be diagnosed before age 45. Just under 10 percent of cases are diagnosed between ages 45 and 54. Over 70 percent of diagnoses occur between 55 and 74. Less than 20 percent of cases are diagnosed at age 75 or older.1
African American men have the highest rates of prostate cancer, followed by Caucasian, Hispanic, Asian/Pacific Islander, and Native American men. African American men also tend to get more aggressive prostate cancer compared to Caucasian men.
Black men in the Caribbean and Europe also have higher rates compared to their neighbors. However, men living in Africa have much lower rates. This suggests that both genes and environment play a role in who gets prostate cancer.1,4
New cases of prostate cancer peaked in the 1990s and began to decline after 2010. Five year survival rates have improved from 66 percent in 1975 to 99 percent in 2011, and continue to decline. Scientists believe the wide-spread use of PSA tests are catching cancer earlier and treatments have improved.1,4
Possible Prostate Cancer Risks
Men over the age of 50 have a significantly greater chance of receiving this diagnosis. In addition, genetics play a key role, and men with first-degree relatives who have had prostate or breast cancer have an increased risk.
There are also some risk factors related to race, as African American men have a higher risk of developing prostate cancer and often have more advanced symptoms. A study in Cancer pointed out that American black men have a 1.8 times greater chance of receiving a prostate cancer diagnosis compared to white men.
There are also lifestyle factors that may be causes of prostate cancer development, the primary one being obesity. In addition, obesity may predict a more aggressive cancer.

Acute Monocytic Leukemia 5
Acute monocytic leukemia is a subtype of a type of leukemia called acute myeloid leukemia . It develops in blood precursor cells that are on their way to becoming immune-system cells called monocytes, explained Laura Romundstad, a registered nurse who helps patients find clinical trials as a clinical trial nurse navigator with the Leukemia & Lymphoma Society .
Monocytes are a major part of the innate immune system , she said.
Treatments for acute monocytic leukemia may include chemotherapy, stem cell transplantation, or targeted therapies.

Stage Iv Prostate Cancer Prognosis
Prostate cancers detected at the distant stage have an average five-year survival rate of 28 percent, which is much lower than local and regional cancers of the prostate. This average survival rate represents stage IV prostate cancers that have metastasized beyond nearby areas to lymph nodes, organs or bones in other parts of the body.
Myth: If You Have A Low Psa You Don’t Have Prostate Cancer
Fact: PSA levels can be useful in diagnosing prostate cancer, but theyre really only one piece of the larger puzzle. The PSA test is far from perfect, Sartor says. He draws a parallel between low PSA readings and negative mammograms in women. If you have a negative mammogram, it’s not 100 in terms of excluding cancer. The probability is less, but likewise just because your PSA is relatively low, you cant interpret that to mean that there is no cancer present.
However, the opposite can also occur: Sartor described a different scenario in which one of his patients a very bright and accomplished attorney has a biopsy after getting an elevated PSA, and the biopsy came back negative. After this negative result he figured he didnt have cancer, and waited three to four years before having his PSA tested again, Sartor says. Now he has prostate cancer that has spread to other parts of his body. In other words: metastatic disease. He took the negative biopsy as literally meaning he doesn’t have cancer, and it turned out badly for him.
To get the most complete picture of your prostate health, you need to get other diagnostic tests as well. This may mean getting a biopsy. But that standard is changing, says Sartor, citing a major study published in The New England Journal of Medicine in March 2018 and The Lancet in February 2017 that point to the value of a special type of MRI imaging called multiparametric magnetic resonance imaging.

Why Is There No Cure
During most of the 20th century, the number of people killed by cancer every year relative to population size, or the cancer death rate rose steadily to its peak in 1991, according to the ACS’s most recentsummary of the state of cancer in the U.S. Since 1991, the cancer death rate has fallen by 31%, which is equivalent to 3.2 million fewer cancer deaths compared with the death rate in 1991.
The study authors attribute the decrease in cancer death rates to reductions in smoking, earlier detection and better treatments for some cancers. “We have made a lot of progress in the fight against cancer,” said Rebecca Siegel MPH, the lead author of this study.
Yet despite all that progress, a wholesale “cure for cancer” remains elusive for many reasons. The first issue is that cancer is not just one disease that could be eradicated with one cure. Instead, it’s hundreds of diseases, Siegel explained. “We would need hundreds of different types of cures to cure all cancer,” she said.
Another reason it’s hard to cure cancer is that the bar for cancer being cured is incredibly high. Cancer is cured if there are no traces of it in the body and it will never come back or is not expected to come back. But even when all traces of a cancer have disappeared, there’s no way of knowing with certainty that it won’t return.
Genetic Testing For Prostate Cancer
You may hear a lot about genetics or genomics. Both terms are related to genes and cell DNA, but they are different. These tests are being used to learn more about the DNA of cancer cells, and link DNA mutations with treatments. In the future, genetic testing may be the first step doctors take when diagnosing prostate cancer.

Prostate Cancer Risk Factors
A risk factor is anything that raises your risk of getting a disease such as cancer. Different cancers have different risk factors. Some risk factors, like smoking, can be changed. Others, like a persons age or family history, cant be changed.
But having a risk factor, or even several, does not mean that you will get the disease. Many people with one or more risk factors never get cancer, while others who get cancer may have had few or no known risk factors.
Researchers have found several factors that might affect a mans risk of getting prostate cancer.
Possible Changes In Circulation And Temperature
- Arms and legs may feel cool to the touch as circulation slows down
- Skin on arms, legs, hands, and feet may darken and look blue or mottled
- Other areas of the body may become either darker or paler
- Skin may feel cold and either dry or damp
- Heart rate may become fast, faint, or irregular
- Blood pressure may get lower and become hard to hear

What Is A Normal Psa Test Result
There is no specific normal or abnormal level of PSA in the blood, and levels may vary over time in the same man. In the past, most doctors considered PSA levels of 4.0 ng/mL and lower as normal. Therefore, if a man had a PSA level above 4.0 ng/mL, doctors would often recommend a prostate biopsy to determine whether prostate cancer was present.
However, more recent studies have shown that some men with PSA levels below 4.0 ng/mL have prostate cancer and that many men with higher levels do not have prostate cancer . In addition, various factors can cause a mans PSA level to fluctuate. For example, a mans PSA level often rises if he has prostatitis or a urinary tract infection. Prostate biopsies and prostate surgery also increase PSA level. Conversely, some drugsincluding finasteride and dutasteride , which are used to treat BPHlower a mans PSA level. PSA level may also vary somewhat across testing laboratories.
Another complicating factor is that studies to establish the normal range of PSA levels have been conducted primarily in populations of White men. Although expert opinions vary, there is no clear consensus regarding the optimal PSA threshold for recommending a prostate biopsy for men of any racial or ethnic group.
In general, however, the higher a mans PSA level, the more likely it is that he has prostate cancer. Moreover, a continuous rise in a mans PSA level over time may also be a sign of prostate cancer.

What Should I Expect As My Cancer Progresses
How does prostate cancer spread?
Prostate cancer cells can move from the prostate to other parts of the body through the blood stream. Or they can spread to the lymph nodes near the prostate and then travel through the lymph vessels to other parts of your body. Lymph nodes and lymph vessels are part of your lymphatic system and are found throughout your body.
Prostate cancer most commonly spreads to the bones and lymph nodes. It can also spread to, or press on, the tube you urinate through , the bladder, the tubes that carry urine from the kidneys to the bladder and part of the bowel . Prostate cancer may spread to other parts of the body, including the lungs and liver. But this is less common.
If tests and scans show that your cancer is spreading, ask your doctor what will happen next. This can help you and your family prepare for what to expect. Find out more about advanced prostate cancer and treatments.

How does prostate cancer cause problems?
Prostate cancer can cause problems if it is pressing on your bones or nerves. It can also cause problems by stopping your normal cells from working properly.
What problems can advanced prostate cancer cause?
The symptoms and problems you have will depend on where the cancer has spread to. Even though your cancer is still growing, you will still be able to have treatment to help manage these problems.
Advanced prostate cancer problems may include:

Whos At Risk For Prostate Cancer
All men are at risk of having prostate cancer. About one man in nine will be diagnosed with it during their lifetime, but only one in 39 will die of this disease. About 80% of men who reach age 80 have cancer cells in their prostate. Besides being male, there are other things that contribute to the risk.

What You Need To Know About The Prostate Chance Of Dying From Prostate Cancer
A enlarged prostate can also cause blockages in the urethra. A blocked urethra can also damage the kidneys. A patient suffering from an enlargement of the prostate may have pain in his lower abdomen and genitals. If pain is present, a digital rectal examination will reveal hard areas. A doctor may prescribe surgery or perform an endoscopic procedure. If the enlarged prostate is not completely removed, it will shrink.
While the size of an enlarged prostate will influence the extent of urinary symptoms, men may experience a range of urinary symptoms. Some men have minimal or no symptoms at all. Some men will have a very enlarged prostate, whereas others will have a mild enlargement. Generally, the symptoms can stabilize over time. Some men may have an enlarged prostate but not notice it. If they have an enlarged colon, their physician can perform a TURP procedure.
Myth: Prostate Cancer Treatment Always Causes Incontinence
Fact: Next to sexual function, men worry most about urinary incontinence as a result of prostate cancer treatment. Sartor says sexual side effects are more common than the urinary side effects the year after surgery. The majority of people do not have significant urinary problems.
If you do have bladder problems, youre more likely to face minor leakage than major accidents and in most men, the situation is temporary or treatable.
To help ensure the best outcome after surgery, Sartor recommends looking for a surgeon who has performed the procedure many times surgeons who are on their 900th procedure, for example, not their 41st. Experience does matter, he says. Its important to consider.

Understanding The Underlying Causes
For cancer researchers in general, were always seeking out the origins. Where does it start, what cells does it start in, how is it co-opting the processes of normal cells to evade the immune system or invade areas where it shouldnt be? says UCLAs Dr. Garraway. Just like other cancers, the whole idea is to understand the biology of the prostate tumors better so you can find the Achilles heel of that tumor.
The challenge, Garraway tells Ars, is that for a long time, research into what causes prostate cancer growth was focused on the indolent versions of the disease that were curable. More surgeries removed slow-growing tumors, leaving researchers with more access to these tissue samples. Metastatic patients were less likely to undergo surgery because their cancers had spread to other parts of their body, so those samples were studied less often.
For those 10 percent or so who are destined to have this metastatic disease, at least half of them already had spreading of their cancer at diagnosis, she says. They werent surgical candidates, so we werent capturing their tissues. And its a challenge to get enough tissue from a metastatic lesion.
Most men are diagnosed with prostate cancer in their senior years and only 1 out of 36 men die from it. Death from prostate cancer most often happens when cancer has spread to other organs in the body. This is known as the advanced stage of prostate cancer.
How Does The Spread Of Prostate Cancer Occur
Prostate cancer is slow-growing cancer, and for this reason, it is often caught early and treated successfully. However, the cancer cells can spread outside the prostate or urethra to neighboring tissue that often begins with the bones. Once this occurs, this is one of the significant signs you are dying of prostate cancer.
The cells could migrate to your lymph nodes, and from there spread to other parts of the body, and they could also metastasize through the blood. Some types of prostate cancer, such as carcinomas could spread more aggressively, but they are rare.

Are There Side Effects Of The Combination Approach
There is a slightly higher chance that patients who receive the combined therapy will have rectal irritation or urinary side effects, both of which are common with any radiation treatment given to the prostate. But at MSK, we routinely use sophisticated planning techniques that help us reduce the dose given to normal tissues such as the rectum, bladder, and urethra, lessening the chances of side effects and complications.
In addition, at MSK, we routinely use a rectal spacer gel, which we inject between the prostate and the rectum while the patient is under mild anesthesia, to create a buffer between these two tissues. By creating this space, we can further reduce the dose of radiation that the rectum is exposed to. This leads to fewer side effects for the patient. The rectal spacer gel is biodegradable and after a few months dissolves on its own within the body, causing no harm or long-term effects.
How Does Prostate Cancer Kill You In The End
Prostate cancer is the most common cancer after skin cancer in men in the US and the second leading cause of cancer death. Prostate-specific antigen testing has made the detection of prostate cancer easier in its early stages. Ninety-two out of 100 men get diagnosed when the cancer is limited to the prostate.
Most men are diagnosed with prostate cancer in their senior years and only 1 out of 36 men die from it. Death from prostate cancer most often happens when cancer has spread to other organs in the body. This is known as the advanced stage of prostate cancer.
The chances of survival decrease as cancer spreads beyond the prostate. If cancer has metastasized to other parts of the body, only three out of 10 men will survive for five years after the diagnosis.
Advanced stage prostate cancer or metastasized prostate cancer
Cancerous cells may spread to organs other than the site of origin. In the case of prostate cancer, this tendency is decreased, but it can happen. Advanced stage prostate cancer is defined based on the Gleason score, which is based on the TNM staging of cancer. T stands for tumor size, N stands for lymph node involvement and M stands for metastasis.
Prostate cancer can kill in the end through metastases that can develop in
Metastasis to the liver can affect the livers ability to filter out toxins from the body. This can eventually lead to jaundice, nausea, loss of appetite and weight loss.
