Prostate cancer is cancer that occurs in the prostate — a small walnut-shaped gland in men that produces the seminal fluid that nourishes and transports sperm. Prostate cancer is common these days than some time back .Have talked a lot about cervical cancer today i want to make a clear picture of what a prostate cancer is, how to prevent and how it is treated.

Prostate cancer is one of the most common types of cancers in men. Usually prostate cancer grows slowly and is initially confined to the prostate gland, where it may not cause serious harm. However, while some types of prostate cancer grow slowly and may need minimal or even no treatment, other types are aggressive and can spread quickly.
Prostate cancer that’s detected early — when it’s still confined to the prostate gland — has a better chance of successful treatment.

Debate continues regarding the risks and benefits of prostate cancer screening, and medical organizations differ on their recommendations. Discuss prostate cancer screening with your doctor. Together, you can decide what’s best for you.
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 also break off and spread (metastasize) to other parts of the body.
Factors that can increase your risk of prostate cancer include:
Age. Your risk of prostate cancer increases as you age.
Race. For reasons not yet determined, black men carry 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.
Family history. 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:
A.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.
B.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.
c.Erectile dysfunction. Erectile dysfunction can result from 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.
Your prostate cancer treatment options depend on several factors, such as how fast your cancer is growing, how much it has spread and your overall health, as well as the potential benefits or side effects of the treatment.
Immediate treatment may not be necessary
For men diagnosed with low-risk prostate cancer, treatment may not be necessary right away. Some men may never need treatment. Instead, doctors sometimes recommend active surveillance.
In active surveillance, regular follow-up blood tests, rectal exams and possibly biopsies may be performed to monitor progression of your cancer. If tests show your cancer is progressing, you may opt for a prostate cancer treatment such as surgery or radiation.
Active surveillance may be an option for cancer that isn’t causing symptoms, is expected to grow very slowly and is confined to a small area of the prostate. Active surveillance may also be considered for someone who has another serious health condition or who is of an advanced age that makes cancer treatment more difficult.
Active surveillance carries a risk that the cancer may grow and spread between checkups, making the cancer less likely to be cured.
1.Surgery to remove the prostate
Surgery for prostate cancer involves removing the prostate gland (radical prostatectomy), some surrounding tissue and a few lymph nodes. Radical prostatectomy can be performed in several ways:
Discuss with your doctor which type of surgery is best for your specific situation.
Radical prostatectomy carries a risk of urinary incontinence and erectile dysfunction. Ask your doctor to explain the risks you may face based on your situation, the type of procedure you select, your age, your body type and your overall health.
Radiation therapy uses high-powered energy to kill cancer cells. Prostate cancer radiation therapy can be delivered in two ways:
Side effects of radiation therapy can include painful, frequent or urgent urination, as well as rectal symptoms such as loose stools or pain when passing stools. Erectile dysfunction can also occur.
Hormone therapy is treatment to stop your body from producing the male hormone testosterone. Prostate cancer cells rely on testosterone to help them grow. Cutting off the supply of testosterone may cause cancer cells to die or to grow more slowly.
Hormone therapy options include:
Hormone therapy is used in men with advanced prostate cancer to shrink the cancer and slow the growth of tumors. In men with early-stage prostate cancer, hormone therapy may be used to shrink tumors before radiation therapy, which can increase the likelihood that radiation therapy will be successful.
Side effects of hormone therapy may include erectile dysfunction, hot flashes, loss of bone mass, reduced sex drive and weight gain.
4.Freezing prostate tissue
Cryosurgery or cryoablation involves freezing tissue to kill cancer cells.
During cryosurgery for prostate cancer, small needles are inserted in the prostate using ultrasound images as guidance. A very cold gas is placed in the needles, which causes the surrounding tissue to freeze. A second gas is then placed in the needles to reheat the tissue. The cycles of freezing and thawing kill the cancer cells and some surrounding healthy tissue.
Initial attempts to use cryosurgery for prostate cancer resulted in high complication rates and unacceptable side effects. However, newer technologies have lowered complication rates, improved cancer control and made the procedure easier to tolerate. Cryosurgery is more frequently used as a salvage therapy for men who haven’t been helped by radiation therapy.
Chemotherapy uses drugs to kill rapidly growing cells, including cancer cells. Chemotherapy can be administered through a vein in your arm, in pill form or both.
Chemotherapy may be a treatment option for men with prostate cancer that has spread to remote body locations. Chemotherapy may also be an option for cancers that don’t respond to hormone therapy.
Permanent prostate brachytherapy
Biological therapy (immunotherapy) uses your body’s immune system to fight cancer cells. One type of biological therapy called sipuleucel-T (Provenge) has been developed to treat advanced, recurrent prostate cancer.
This treatment takes some of your own immune cells, genetically engineers them in a laboratory to fight prostate cancer, then injects the cells back into your body through a vein. Some men do respond to this therapy with some improvement in their cancer, but the treatment is very expensive and requires multiple treatments.
