What is Prostate Cancer?

Prostate cancer is a cancerous disease that begins in the prostate gland and involves uncontrolled growth of cells in this gland. Prostate cancer is among the most common cancers in men and typically occurs in advanced age. However, in rare cases, it can also be diagnosed in younger individuals. For instance, prostate cancer can be identified in a man as young as 40 years old.

Prostate cancer treatment can vary based on the cancer's grading (Gleason grade), whether the cancer has spread beyond the prostate to lymph nodes or distant organs, and the overall health of the patient. Treatment options include surgery, radiation therapy, hormone therapy, chemotherapy, and targeted therapies. For example, in a patient diagnosed with early-stage prostate cancer, surgical intervention is often considered the most suitable treatment option. However, in a patient with advanced-stage prostate cancer, a combination of radiation therapy and hormone therapy may be preferred.

With early diagnosis and appropriate treatment, prostate cancer can be treated successfully in many patients, and these patients can live healthy lives for a long time. However, since each patient's general health condition and stage of cancer are different, the effectiveness and results of treatment options may vary from person to person. Therefore, prostate cancer treatment requires a personalized approach and should be planned specifically for patients' conditions.

What are the Symptoms of Prostate Cancer? 

The symptoms of prostate cancer may not cause any discomfort in the early stages and may become apparent as the disease progresses. Therefore, men with a family history of prostate cancer should undergo prostate screening at the age of 40, and healthy individuals, even without symptoms, should consider screening starting from the age of 50. Symptoms may resemble those seen in benign prostatic enlargement. These symptoms include; 
•    Difficulty or straining during urination.
•    Increased need to urinate, especially at night.
•    Weak or interrupted urine flow.
•    Burning or pain during urination.
•    Blood in urine or semen.
•    Pain or discomfort in the pelvic area.
•    Erectile problems.
•    Detection of hardened or firm masses (during a prostate examination).

These symptoms may be associated with other health issues; however, it's essential to consider that they could also be indicative of symptoms of prostate cancer.

What are the Stages of Prostate Cancer? 

The stages of prostate cancer are a classification system used to determine how much the cancer has spread and how aggressive it is. Staging plays a crucial role in determining treatment options for cancer. Prostate cancer is typically classified into one of the following stages:

1.  Stage I: Prostate cancer is only present in the prostate gland and has not spread.
2. Stage II: The cancer has spread from the prostate gland to surrounding tissues but has not reached lymph nodes or other organs yet..
3. Stage III: The cancer has spread to organs outside the prostate or to lymph nodes..
4. Stage IV: The cancer has not only spread to organs outside the prostate or to lymph nodes but has also metastasized to distant organs.

Why Does Prostate Cancer Occur? 

The exact causes of prostate cancer are not fully understood, but it is believed that several factors may contribute to the development of prostate cancer. These factors may include genetic predisposition, age, race, hormonal factors, environmental factors, and lifestyle factors. 
The lack of precise knowledge about the exact causes of prostate cancer does not imply evidence for a single factor playing a role in its development. For example, some studies have shown that genetic predisposition may increase the risk of prostate cancer. However, even in such cases, many individuals with a family history of prostate cancer do not develop the disease. Therefore, stating that genetic predisposition alone is effective in the formation of prostate cancer can be misleading. The factors leading to prostate cancer are listed as follows:

Genetic Predisposition: Individuals with a family history of prostate cancer are observed to have a higher risk compared to others. Alterations in certain genes can contribute to the development of prostate cancer.
Age: The risk of prostate cancer increases with age. It is particularly more common in men aged 50 and above.
Race: Prostate cancer is more commonly observed in African-American men. This group tends to encounter more aggressive and advanced-stage cancers compared to other ethnic groups.
Hormonal Factors: Testosterone hormone may play a role in the growth of prostate cancer. Higher levels of testosterone can increase the risk of prostate cancer.
Environmental Factors: Some environmental factors can increase the risk of prostate cancer. For example, factors such as excessive weight, smoking, and exposure to certain chemicals can elevate this risk..
Lifestyle Factors: Factors like irregular diet, sedentary lifestyle, obesity, and alcohol consumption can increase the risk of prostate cancer. Adopting a healthy lifestyle can play a significant role in reducing the risk of prostate cancer.

How is Prostate Cancer Diagnosed? 

Several different methods can be used for the diagnosis of prostate cancer. These include digital rectal examination, PSA blood test, and prostate biopsy. Digital rectal examination is a method that allows the doctor to check the prostate with their finger. The PSA blood test, while not specific to prostate cancer, can indicate an elevated level, suggesting a higher risk of cancer. Finally, prostate biopsy involves taking tissue samples from suspicious areas and sending them for laboratory analysis. The combination of these methods assists in the diagnosis of prostate cancer.

Prostate cancer diagnosis can be made using one or a combination of these methods. Early diagnosis is crucial for the successful treatment of prostate cancer, so regular doctor check-ups and screening tests are important. 

What are the Treatment Methods for Prostate Cancer?

Prostate cancer treatment can vary depending on the stage of cancer, the overall health of the patient, and other factors. Here are some common methods used in prostate cancer treatment:

Surgery: One of the most commonly used methods in the treatment of prostate cancer is surgery. This operation, performed with the aim of completely or partially removing the prostate gland, is carried out to prevent the spread of cancer and preserve the patient's health..

Radiation Therapy: Another method used in the treatment of prostate cancer is radiation therapy. Cancer cells are targeted and destroyed using high-energy rays. Radiation therapy is considered as an alternative to surgical methods in suitable cases or for patients who are not suitable for intervention.
Hormone Therapy: Prostate cancer can grow under the influence of the male hormone testosterone. Therefore, hormone therapy is used to stop or slow down the growth of cancer cells. It is employed for patients with advanced-stage prostate cancer (spread to distant organs). Hormone therapy can also be applied after surgery or radiation therapy.

Chemotherapy: Chemotherapy treatment can be applied in advanced stages of prostate cancer or when it has spread. Chemotherapy involves the use of drugs that kill or stop the growth of cancer cells. However, chemotherapy is typically administered to patients who have developed resistance to hormone therapy, do not respond to other treatment methods, or are in an advanced stage of the disease.

Targeted Therapies: Targeted drugs are medications that prevent or block cancer cells from attacking specific targets. Drugs that specifically target hormone receptors or block the growth signals of cancer cells can be used as targeted therapies. These treatments aim to minimize side effects by directly affecting cancer cells. Targeted therapies can be used in addition to or sometimes instead of chemotherapy. These treatments generally act more specifically on cancer cells and can improve the quality of life for patients.

Immunotherapy: Immunotherapy is a treatment method used to stimulate the body's own immune system to fight against cancer cells. The use of immunotherapy is being investigated in some prostate cancer patients. This treatment aims to enhance the immune system's ability to destroy cancer cells by strengthening its response against them.

Immunotherapy can be used in addition to other treatment methods or on its own. The effectiveness of immunotherapy in the treatment of prostate cancer is under investigation, and it is anticipated to become more widely used in the future.

Prostate cancer treatment often involves a combination of multiple methods, and doctors assess the patient's condition to determine the most suitable treatment plan. Treatment options and approaches can vary individually, so it is important to create a personalized treatment plan for each patient.
