Prostate Cancer – Causes
It’s not clear what causes prostate cancer.
Doctors know that prostate cancer begins when some cells in your prostate become abnormal. Mutations in the abnormal cells’ DNA cause the cells to grow and divide more rapidly than normal cells do. The abnormal cells continue living, when other cells would die. The accumulating abnormal cells form a tumor that can grow to invade nearby tissue. Some abnormal cells can break off and spread (metastasize) to other parts of the body.
Factors that can increase your risk of prostate cancer include:
- Older age. Your risk of prostate cancer increases as you age.
- Being black. Black men have a greater risk of prostate cancer than do men of other races. In black men, prostate cancer is also more likely to be aggressive or advanced. It’s not clear why this is.
- Family history of prostate or breast cancer. If men in your family have had prostate cancer, your risk may be increased. Also, if you have a family history of genes that increase the risk of breast cancer (BRCA1 or BRCA2) or a very strong family history of breast cancer, your risk of prostate cancer may be higher.
- Obesity. Obese men diagnosed with prostate cancer may be more likely to have advanced disease that’s more difficult to treat.
Complications of prostate cancer and its treatments include:
- Cancer that spreads (metastasizes). Prostate cancer can spread to nearby organs, such as your bladder, or travel through your bloodstream or lymphatic system to your bones or other organs. Prostate cancer that spreads to the bones can cause pain and broken bones. Once prostate cancer has spread to other areas of the body, it may still respond to treatment and may be controlled, but it’s unlikely to be cured.
- Incontinence. Both prostate cancer and its treatment can cause urinary incontinence. Treatment for incontinence depends on the type you have, how severe it is and the likelihood it will improve over time. Treatment options may include medications, catheters and surgery.
- Erectile dysfunction. Erectile dysfunction can be a result of prostate cancer or its treatment, including surgery, radiation or hormone treatments. Medications, vacuum devices that assist in achieving erection and surgery are available to treat erectile dysfunction.
Preparing for your appointment
If you have signs or symptoms that worry you, start by seeing your family doctor or a general practitioner.
If your doctor suspects you may have a problem with your prostate, you may be referred to a urinary tract specialist (urologist). If you’re diagnosed with prostate cancer, you may be referred to a cancer specialist (oncologist) or a specialist who uses radiation therapy to treat cancer (radiation oncologist).
Because appointments can be brief, and because there’s often a lot of ground to cover, it’s a good idea to be prepared. Here’s some information to help you get ready and what to expect from your doctor.
WHAT YOU CAN DO
- Be aware of any pre-appointment restrictions. At the time you make the appointment, be sure to ask if there’s anything you need to do in advance, such as restrict your diet.
- Write down any symptoms you’re experiencing, including any that may seem unrelated to the reason for which you scheduled the appointment.
- Write down key personal information, including any major stresses or recent life changes.
- Make a list of all medications, vitamins or supplements that you’re taking.
- Consider taking a family member or friend along.Sometimes it can be difficult to remember all the information provided during an appointment. Someone who accompanies you may remember something that you missed or forgot.
- Write down questions to ask your doctor.
Your time with your doctor is limited, so preparing a list of questions can help you make the most of your time together. List your questions from most important to least important in case time runs out. For prostate cancer, some basic questions to ask your doctor include:
- Do I have prostate cancer?
- How large is my prostate cancer?
- Has my prostate cancer spread beyond my prostate?
- What is my Gleason score?
- What is my prostate-specific antigen (PSA) level?
- Will I need more tests?
- What are my treatment options?
- Is there one treatment option you think is best for me?
- Do I need cancer treatment right away, or is it possible to wait and see if the cancer grows?
- What are the potential side effects of each treatment?
- What is the chance that my prostate cancer will be cured with treatment?
- If you had a friend or family member in my situation, what would you recommend?
- Should I see a specialist? What will that cost, and will my insurance cover it?
- Are there brochures or other printed material that I can take with me? What websites do you recommend?
In addition to the questions that you’ve prepared to ask your doctor, don’t hesitate to ask other questions during your appointment.
WHAT TO EXPECT FROM YOUR DOCTOR
Your doctor is likely to ask you a number of questions. Being ready to answer them may allow more time later to cover other points you want to address. Your doctor may ask:
- When did you first begin experiencing symptoms?
- Have your symptoms been continuous or occasional?
- How severe are your symptoms?
- What, if anything, seems to improve your symptoms?
- What, if anything, appears to worsen your symptoms?
