Prostate cancer

Symptoms

The symptoms of prostate cancer may be subtle in the early stages and may not appear until the cancer has progressed. Some common symptoms of prostate cancer include:

• Difficulty starting urination or holding back urine
• Weak or interrupted flow of urine
• Frequent urination, especially at night
• Pain or burning during urination
• Difficulty achieving an erection
• Painful ejaculation
• Blood in the urine or semen
• Discomfort or pain in the pelvic area 

If you are experiencing any of these symptoms, it is important to see a doctor for a diagnosis. These symptoms can also be caused by other conditions, such as an enlarged prostate or a urinary tract infection, so it is important to get a proper diagnosis.

Causes

The exact cause of pancreatic cancer is unknown, but there are several factors that may increase the risk of developing the disease. These include:

• Smoking: Smoking tobacco is the leading cause of pancreatic cancer.
• Age: The risk of pancreatic cancer increases with age, and the disease is most commonly diagnosed in people over the age of 65.
• Gender: Men are slightly more likely to develop pancreatic cancer than women.
• Family history: People with a family history of pancreatic cancer are more likely to develop the disease themselves.
• Chronic pancreatitis: Chronic inflammation of the pancreas (pancreatitis) may increase the risk of pancreatic cancer.
• Obesity: Being overweight or obese may increase the risk of pancreatic cancer.
• Diabetes: People with diabetes, especially those who developed the disease at a young age, may have an increased risk of pancreatic cancer. 

It's important to note that having one or more of these risk factors does not mean that a person will definitely develop pancreatic cancer. Many people with these risk factors never develop the disease, and some people with pancreatic cancer have none of these risk factors.

Complications

If prostate cancer is not treated, it can spread (metastasize) to other parts of the body, such as the bones, lymph nodes, and organs. This can lead to a number of complications, including:

• Pain: Cancer that has spread to the bones can cause pain, especially in the back, hips, and pelvis.
• Urinary incontinence: Prostate cancer can damage the muscles and nerves that control urination, leading to incontinence (loss of bladder control).
• Erectile dysfunction: Prostate cancer and its treatment can damage the nerves and blood vessels that are necessary for an erection.
• Loss of fertility: Prostate cancer and its treatment can affect a man's ability to father children.
• Shortness of breath: If the cancer spreads to the lungs, it can cause shortness of breath.
• Swelling in the legs: If the cancer spreads to the lymph nodes in the pelvis, it can cause swelling in the legs.
• Brain metastasis: In rare cases, prostate cancer can spread to the brain, leading to a variety of symptoms, including headache, difficulty speaking, and changes in behavior. 

If you are experiencing any of these complications, it is important to speak with your doctor about treatment options.

How to diagnose it?

There are several tests that can be used to diagnose prostate cancer, including:

• Digital rectal examination (DRE): During a DRE, a doctor inserts a gloved, lubricated finger into the rectum to feel the prostate gland for any abnormalities.
• Prostate-specific antigen (PSA) test: This blood test measures the level of PSA, a protein produced by the prostate gland. Elevated levels of PSA may indicate prostate cancer.
• Biopsy: During a biopsy, a small sample of tissue is taken from the prostate gland and examined under a microscope for cancer cells. This is the only way to definitively diagnose prostate cancer.
• Ultrasound: An ultrasound uses sound waves to create an image of the prostate gland, which can help a doctor determine the size and shape of the gland and look for any abnormalities.
• MRI: An MRI uses magnetic fields and radio waves to create detailed images of the prostate gland. This can help a doctor determine the size and location of any tumors. 

If prostate cancer is diagnosed, additional tests may be done to determine the stage (extent) of the cancer and to help plan treatment. These tests may include a CT scan, bone scan, and PET scan.

How to prevent it?

There is no sure way to prevent prostate cancer, but there are some things that may help reduce your risk:

• Eat a healthy diet: A diet high in fruits, vegetables, and whole grains and low in red meat and dairy products may help reduce the risk of prostate cancer.
• Maintain a healthy weight: Being overweight or obese may increase the risk of prostate cancer.
• Exercise regularly: Regular physical activity may help reduce the risk of prostate cancer.
• Limit your intake of alcohol: Heavy alcohol consumption has been linked to an increased risk of prostate cancer.
• Get screened: Talk to your doctor about whether prostate cancer screening is right for you. If you are at high risk for prostate cancer, your doctor may recommend starting screening at an earlier age.

It is important to note that these measures may not completely prevent prostate cancer, but they may help reduce the risk. If you are concerned about your risk of prostate cancer, it is important to speak with your doctor.

When to see a doctor?

If you are over the age of 50 or have other risk factors for prostate cancer, such as a family history of the disease, it is important to talk to your doctor about whether prostate cancer screening is right for you. Early detection of prostate cancer can increase the chances of successful treatment.
