Overview

Prostate cancer is cancer that occurs in the prostate. The prostate is a small walnut-shaped gland in males that produces the seminal fluid that nourishes and transports sperm. Prostate cancer is one of the most common types of cancer. Many prostate cancers grow slowly and are confined to the prostate gland, where they may not cause serious harm. However, while some types of prostate cancer grow slowly and may need minimal or even no treatment, other types are aggressive and can spread quickly.

What Causes Prostate Cancer?

Researchers do not know exactly what reasons prostate cancer. But they have located some hazard factors and are making an attempt to examine simply how these elements may purpose prostate cells to grow to be cancer cells.

On a fundamental level, prostate cancer is caused through adjustments in the DNA of a normal prostate cell. DNA is the chemical in our cells that makes up our genes, which control how our cells function. We typically look like our dad and mom because they are the source of our DNA. But DNA affects greater than just how we look.

Some genes manage when our cells grow, divide into new cells, and die:

Certain genes that assist cells grow, divide, and continue to be alive are referred to as oncogenes. Genes that typically hold phone growth underneath control, repair mistakes in DNA, or cause cells to die at the proper time are called tumor suppressor genes. Cancer can be prompted through DNA mutations (or other types of changes) that preserve oncogenes grew to become on, or that flip off tumor suppressor genes. These kinds of gene adjustments can lead to cells developing out of control. DNA's adjustments can either be inherited from a father or mother or can be received at some point of a person’s lifetime.
Inherited gene mutations
Some gene mutations can be surpassed from era to technology (inherited) and are found in all cells in the body. Inherited gene adjustments are notion to play a function in about 10% of prostate cancers. Cancer caused by way of inherited genes is called hereditary cancer. Several inherited mutated genes have been linked to hereditary prostate cancer, including:
BRCA1 and BRCA2: These tumor suppressor genes typically help restore mistakes in a cell’s DNA (or purpose the mobile to die if the mistake can’t be fixed). Inherited mutations in these genes greater regularly cause breast and ovarian cancer in women. But changes in these genes (especially BRCA2) also account for a few prostate cancers.
CHEK2, ATM, PALB2, and RAD51D: Mutations in these other DNA restore genes would possibly additionally be responsible for some hereditary prostate cancers.
DNA mismatch repair genes (such as MSH2, MSH6, MLH1, and PMS2): These genes generally help restore errors (mismatches) in DNA that can be made when a telephone is making ready to divide into 2 new cells. (Cells ought to make a new copy of their DNA each time they divide.) Men with inherited mutations in one of these genes have a condition recognized as Lynch syndrome (also known as hereditary non-polyposis colorectal cancer, or HNPCC), and are at improved danger of colorectal, prostate, and some different cancers.
RNA SEL (formerly HPC1): The ordinary function of this tumor suppressor gene is to help cells die when something goes incorrect inside them. Inherited mutations in this gene would possibly let strange cells live longer than they should, which can lead to an increased threat of prostate cancer.
HOXB13: This gene is essential in the development of the prostate gland. Mutations in this gene have been linked to early-onset prostate most cancers (prostate cancer identified at a younger age) that runs in some families. Fortunately, this mutation is rare.
Other inherited gene mutations may account for some hereditary prostate cancers, and research is being accomplished to find these genes.

Acquired gene mutations

Some genes mutate during a person’s lifetime, and the mutation is no longer exceeded on to children. These modifications are observed only in cells that come from the authentic mutated cell. These are called acquired mutations. Most gene mutations associated to prostate cancer appear to develop at some point of a man’s lifestyles as an alternative than having been inherited.
Every time a phone prepares to divide into two new cells, it must copy its DNA. This technique isn't always perfect, and on occasion blunders occur, leaving faulty DNA in the new cell. It’s not clear how often these DNA adjustments might be random events, and how regularly they are influenced by using different elements (such as diet, hormone levels, etc.). In general, the more rapidly prostate cells develop and divide, the extra possibilities there are for mutations to occur. Therefore, something that speeds up this technique may additionally make prostate cancer extra likely.
For example, androgen (male hormones), such as testosterone, promote prostate cellphone growth. Having greater ranges of androgen would possibly make contributions to prostate cancer danger in some men.
Some lookup has determined that men with high degrees of any other hormone, insulin-like growth factor-1 (IGF-1), are extra possibly to get prostate cancer. However, different studies have no longer found such a link. Further research is wanted to make sense of these findings.
As stated in Prostate Cancer Risk Factors, some research have determined that inflammation in the prostate would possibly be linked to prostate cancer. One principle is that infection may lead to cellphone DNA damage, which may want to contribute to a regular mobile phone turning into a cancer cell. More lookup is needed in this area.
Exposure to radiation or cancer-causing chemical substances can purpose DNA mutations in many organs, however so far these elements haven't been shown to be important reasons of mutations in prostate cells.

Conclusion

Aging in the male is intimately associated with both malignant and benign pathologic changes in the prostate. These diseases both increase in incidence with aging. It is estimated that almost 50 percent of men will develop symptoms of BPH in their lifetimes. Fortunately, current medical and surgical options offer good resolution of symptoms. Up to 11 percent of men will develop clinically significant prostate cancer during their lifetimes. However, current treatment options associated with early diagnosis, along with the slow growth of prostate cancers, mean that most men die of illnesses other than prostate cancer.
