What is the Cause of Prostate Cancer?

Prostate cancer is caused by mutations in the DNA of the prostate cells. These abnormal cells continue to divide and grow until they form a tumor. If not treated, aggressive prostate cancer cells can spread to other parts of the body. The disease is inherited, so individuals with a family history are more likely to develop the condition. However, there are a number of risk factors that can increase a person’s risk of developing prostate cancer.

Oncogenes

Prostate cancer is caused by changes in the oncogenes in the prostate, a group of genes that help cells grow and divide. These genes also interact with tumor suppressors, which help cells grow under control, repair mistakes in DNA, and die at the right time. Genetic mutations, however, can change the expression of these genes and lead to prostate cancer. This condition is known as hereditary prostate cancer.

Proto-oncogenes are normal genes that help cells grow and reproduce. However, when these genes become mutated, they are permanently activated and start making proteins that code for cancer. This is known as a gain-of-function mutation, which changes the function of the cell from one of survival to growth. It is also one of the defining features of cancerous tumors.

Human papillomaviruses have also been implicated in the development of prostate cancer. In 1965, Hill AB published a paper in which he argued that the environment plays a role in disease. Prostate published an article in 2002 that reported the discovery of human papillomaviruses in prostate tissue. This study identified multiple microorganisms and a pathogen signature.

ERG is an important example of a proto-oncogene. Its overexpression is associated with aggressive disease and the presence of PIN and ERG fusion messenger RNAs in early prostate cancer. The researchers in this study also noted that there is an association between the overexpression of ERG and ETS gene in prostate cancer. Moreover, ERG overexpression is associated with biochemical recurrence of prostate cancer.

Tumor suppressor genes

While it is still not known for sure which gene causes prostate cancer, researchers have made some progress in discovering the causes. Among these are oncogenes and tumor suppressor genes. Oncogenes regulate cell division, so when they are turned on, cancer cells develop. Tumor suppressor genes, on the other hand, regulate cell division by keeping cells healthy. Many cancers are inherited and are associated with mutations in tumor suppressor genes.

In this study, researchers identified TP53 and PTEN pathogenic TSG-alt as predicting poor prognosis at early disease stages. In addition, the loss of these two TSGs is associated with early disease progression, irrespective of treatment choice. Additionally, these findings outperformed other clinical variables in multivariable analyses. The increasing use of tumor sequencing in clinical trials may also indicate the need for molecular stratification of prognosis algorithms. If this finding is confirmed, it will improve prognostic tools.

Loss of ANX7 expression in human prostate tumor tissue has been correlated with clinically significant stages of prostate cancer. Further, loss of ANX7 expression is a biomarker of tumor cell proliferation and progression to late-stage prostate cancer. Molecular analysis of prostate tissue microarrays, which can study hundreds of tumors simultaneously, has also revealed that reduction of ANX7 expression is limited to metastases.

Overexpression of RBM5 in prostate cancer PC-3 cells induces apoptosis. RBM5 modulates the mitochondrial apoptotic pathway and may therefore represent a promising target for gene therapy in prostate cancer. Therefore, it is important to identify the specific tumor suppressor gene that controls the expression of RBM5 in prostate cells. The research has also identified the role of RBM5 in prostate cancer pathogenesis and treatment.

Age

Many factors influence a person’s risk for cancer, including age, certain behaviors, substances, and conditions. However, the majority of cancers are caused by a combination of risks. Age, for example, significantly increases a man’s risk. Although a man’s age isn’t the only cause of prostate cancer, it certainly contributes to the risk. People over 65 are more likely to develop prostate cancer than men younger than forty.

An enlarged prostate tends to grow larger with age. It may grow up to the size of a walnut by his forties and fifties, or it can become a lemon-sized mass by the time he’s in his 60s. As the prostate grows, it presses against the urethra and bladder and may impede or even prevent urine flow. Some men may find it difficult to start or stop a urine stream, or they may experience an urge to pee at odd times, such as when they’re sleeping.

While age plays a role in developing prostate cancer, some risk factors must be considered. Prostate cancer runs in families. Having a father or brother who has been diagnosed with the disease doubles a man’s risk of developing the disease. Having a brother or several other relatives with the disease also increases the risk. If they had the disease before 60, their risk is nearly doubled. Prostate cancer is more likely to recur if the man is older than 60.

Despite many factors that increase a man’s risk of developing prostate cancer, it’s rare in men under 50. Prostate cancer is associated with various genetic changes and is not always caused by age. Genetic changes in a man’s DNA are often inherited or acquired. Inherited genetic changes also increase a man’s risk. Inheritance can also increase the risk of developing prostate cancer.

Race

While the relationship between race and prostate cancer has been a longstanding mystery, several recent studies suggest that racial differences in the disease may be related to certain baseline characteristics. In a setting with homogeneous racial and ethnic composition, biological characteristics associated with race are easier to measure. For example, men from similar ethnic groups are more likely to live in areas with better environmental pollution, which may affect their overall health. Furthermore, some studies suggest that men from certain ethnic groups may have a greater propensity to drink and smoke than others. While a racial or ethnic difference in risk is hardly conclusive, these studies do demonstrate a correlation between prostate cancer and mortality.

However, there are a number of other factors that might contribute to this disparity. For instance, African-American men were found to have shorter repeats than white men and Asian men. However, the results of the study showed no significant differences in the mean number of repeats between white and Asian men. As a result, there may be a link between race and prostate cancer. If this association between race and prostate cancer is present, it might be possible to use such a relationship to better understand the disease.

Prostate cancer is rare in African-American men younger than 40, but the risk of developing it rapidly increases after age 50. Today, more than half of all cases of prostate cancer occur in men over 65. However, men of African descent and men of African ancestry have a higher risk of developing the disease, and they are diagnosed earlier than white men. In contrast, Asian and Hispanic men tend to experience a lower risk of prostate cancer.

Genetics

The recent GU-ASCO meeting in San Francisco, USA, provided an opportunity to hear from an emerging expert on genetics and prostate cancer, Heather Cheng. She discussed the role of genetic mutations in treatment for this disease and the science behind PARP inhibitors. In this interview, Dr. Cheng shares her experiences with prostate cancer and her research into the intersection of cancer genetics and prostate cancer. Listen to this interview to learn more about the latest developments in this field.

Although scientists have been studying a number of genetics and environmental risk factors for prostate cancer for years, a recent study reveals that one-third of the inherited risk for prostate tumors can be explained by environmental factors. In fact, the study analyzed 87,000 individuals from different ethnicities to identify 23 new genetic variants, the largest single-study approach to date. Ultimately, these findings can be used to better understand the cause and risk of prostate cancer in the future.

As the research into these genes progresses, scientists are looking for common germline mutations associated with this disease. The aim is to identify genes in families that have high rates of the disease. But finding a gene associated with the disease is not always easy. Some researchers have found loci on chromosome 1 and X that may be linked to the development of prostate cancer. But further research is necessary to understand how this cancer is caused.

While it is possible to identify a specific genetic mutation that is associated with the development of prostate cancer, genetic testing is not a cure for the disease. While the results of this test are not particularly informative, they do show whether a person has a higher risk than others. For example, BRCA1 gene carriers may be advised to undergo surgery after having children. While this procedure may also be necessary in some cases, it is not widely available and may not be covered by all health insurance plans.
