Prostate Cancer: Understanding the Basics and Facts You Need to Know

Prostate Cancer facts

Prostate cancer is one of the most common cancers among men, with over 1.4 million cases diagnosed worldwide each year. Despite its prevalence, there are still many misconceptions and misunderstandings about this disease. In this blog article, we will provide an overview of prostate cancer, including its causes, symptoms, and treatment options. We will also debunk common myths and provide the facts you need to know to stay informed about this important health issue. Whether you are a man at risk for prostate cancer or a concerned loved one, this blog will provide valuable information to help you understand the basics of prostate cancer.

Prostate cancer

Prostate cancer is a type of cancer that develops in the prostate gland, a small gland located just below the bladder in men. The prostate gland produces a fluid that nourishes and transports sperm during ejaculation. Age and family history are known risk factors for prostate cancer, with men over the age of 50 and men with a family history of prostate cancer being at higher risk.

As the cancer grows, it can cause a variety of symptoms, including urinary problems, blood in the urine or semen, pain and discomfort, erectile dysfunction, and other symptoms.

Prostate cancer can be detected with a PSA test, which measures the level of prostate-specific antigen (PSA) in the blood. However, the PSA test is not always accurate, and elevated PSA levels can be caused by other conditions besides cancer.

Types of prostate cancer

There are different types of prostate cancer, which are classified based on the appearance of the cancer cells under a microscope. The two most common types of prostate cancer are:

  • Adenocarcinoma: Adenocarcinoma is the most common type of prostate cancer, accounting for about 95% of all cases. It develops in the gland cells that produce prostate fluid and is usually slow-growing.
  • Small cell carcinoma: Small cell carcinoma is a less common type of prostate cancer, accounting for less than 5% of cases. It develops in the small cells of the prostate and is usually more aggressive and fast-growing than adenocarcinoma.

There are also other less common types of prostate cancer, including:

  • Sarcomas: Sarcomas are rare types of cancer that develop in the connective tissue or muscles of the prostate gland.
  • Neuroendocrine tumors: Neuroendocrine tumors are rare types of cancer that develop in the hormone-producing cells of the prostate gland.
  • Transitional cell carcinomas: Transitional cell carcinomas are rare types of cancer that develop in the lining of the bladder and can spread to the prostate gland.

The type of prostate cancer can affect treatment options and prognosis. Adenocarcinoma is usually treated with surgery, radiation therapy, or hormone therapy, while small cell carcinoma may require more aggressive treatment, such as chemotherapy. It’s important to discuss the type of prostate cancer with a healthcare provider to determine the best course of treatment.

Stages of prostate cancer

Prostate cancer can be divided into different stages based on the extent of the cancer and whether it has spread to other parts of the body. The most used staging system for prostate cancer is the TNM system, which stands for Tumor, Nodes, and Metastasis. The stages of prostate cancer are:

  • Stage I: The cancer is small, confined to the prostate gland, and has not spread to nearby lymph nodes or other organs.
  • Stage II: The cancer is still confined to the prostate gland, but is larger and may be more aggressive than in Stage I.
  • Stage III: The cancer has spread beyond the prostate gland to nearby tissues or organs, such as the seminal vesicles.
  • Stage IV: The cancer has spread to other parts of the body, such as the bones, liver, or lungs.

Each stage is further divided into subcategories based on the size and extent of the cancer. The stage and subcategory of the cancer help guide treatment decisions and predict the prognosis, or the expected outcome of the cancer.

It’s important to note that prostate cancer can be slow-growing and may not cause symptoms or require treatment for many years. In some cases, active surveillance or watchful waiting may be recommended for early-stage prostate cancer. However, more aggressive cancers may require immediate treatment to prevent the cancer from spreading and causing serious complications.

Prostate cancer symptoms

As the cancer grows, it can cause a variety of symptoms, including:

  • Urinary problems: Prostate cancer can cause urinary problems such as a weak or interrupted urine flow, frequent urination (especially at night), difficulty starting or stopping urination, and the need to urinate urgently.
  • Pain and discomfort: Prostate cancer can cause pain or discomfort in the pelvic area, lower back, or upper thighs.
  • Erectile dysfunction: Prostate cancer can affect a man’s ability to achieve or maintain an erection.
  • Other symptoms: In rare cases, advanced prostate cancer symptoms such as weight loss, fatigue, and swelling in the legs or pelvic area.

Prostate cancer treatment

Prostate cancer treatment options depend on several factors, including the stage and severity of the cancer, the patient’s age and overall health, and personal preferences.

  • Active surveillance: For low-risk prostate cancer, active surveillance may be recommended. This involves monitoring the cancer with regular PSA tests, digital rectal exams, and biopsies, but not treating it right away.
  • Surgery: Surgery involves removing the prostate gland and any cancerous tissue surrounding it. Surgery may be recommended for early-stage prostate cancer or when other treatment options have failed.
  • Radiation therapy: This treatment may be used alone or in combination with other treatments, such as surgery or hormone therapy.
  • Hormone therapy: Hormone therapy is used to block the production of testosterone, which can fuel the growth of prostate cancer cells. Hormone therapy may be used alone or in combination with other treatments.
  • Chemotherapy: Chemotherapy uses drugs to kill cancer cells. Chemotherapy may be used for advanced prostate cancer that has spread to other parts of the body.
  • Immunotherapy: Immunotherapy uses the body’s own immune system to fight cancer cells. This treatment may be used for advanced prostate cancer.

The choice of treatment depends on the individual patient’s situation and should be made in consultation with a healthcare provider. It’s important to discuss the risks and benefits of each treatment option and to consider the potential side effects.


In conclusion, prostate cancer is a common type of cancer that affects the prostate gland in men. It is important to be aware of the risk factors, symptoms, and screening options for prostate cancer.

If you are concerned about prostate cancer or are experiencing symptoms such as difficulty urinating or blood in the urine, it’s important to talk to a healthcare provider. They can perform tests to diagnose or rule out prostate cancer and recommend the best course of treatment based on the stage and type of cancer.

Remember to maintain a healthy lifestyle by exercising regularly, eating a balanced diet, and avoiding tobacco and excessive alcohol consumption, as these can reduce the risk of developing prostate cancer.
