The prostate gland is located in the male reproductive system. It is an important part of the male reproductive system, as it produces and secretes a fluid that is used to transport sperm from the testicles to the urethra. The prostate gland also secretes some substances that are involved in the production of semen.

There are two lobes to the prostate gland. One lobe is anterior and the other is posterior. The posterior lobe is larger than the anterior lobe.

The prostate gland is about 1-1.5 cm long and about 0.8 cm wide. It is located at the base of the bladder. The anterior lobe is located in front of the rectum, while the posterior lobe is behind the rectum.

The prostate gland consists of a fibromuscular stroma, which is surrounded by smooth muscle tissue. There are no glands present in the prostate gland. The stroma consists of two layers of connective tissue, with a layer of smooth muscle fibers between them. The inner layer is composed of dense collagenous fibers, while the outer layer is composed of loose, elastic fibers.

The prostate gland produces and secretes a fluid called prostatic fluid. Prostatic fluid is produced in the prostate gland by the epithelial cells lining the ducts of the gland. These cells produce a protein called prostate specific antigen (PSA). PSA is a glycoprotein that is found in the prostate gland. It is secreted into the prostatic fluid.

Prostate cancer is the most common cancer among men. Prostate cancer is a malignant neoplasm that originates in the cells of the prostate gland. It is also known as adenocarcinoma or adenocarcinoma of the prostate.

There are two types of prostate cancer:

1. Benign prostatic hyperplasia (BPH) – BPH is not a cancer. It is a condition in which the prostate gland enlarges. This causes problems with urination. BPH is a common problem in older men.

2. Prostate cancer – This is a malignant neoplastic disease that develops in the prostate gland.

Symptoms of Prostate Cancer:

There are no symptoms of prostate cancer until the cancer has grown large enough to cause problems. When prostate cancer is detected early, it can be treated successfully. But when prostate cancer is detected late, there may be many complications and the patient may die from this disease.

Some of the symptoms of prostate cancer are:

1. Difficulty in urinating – This is due to the pressure on the urethra.

2. Painful urination – This is caused by the tumor pressing on the nerves that control the muscles of the bladder and urethra.

3. Blood in the urine – This is caused by the tumors bleeding into the urinary tract.

4. Weakness – This is due to the tumors affecting the nerves that supply the muscles.

5. Enlarged prostate gland – This is caused by the growth of tumors in the prostate gland.

6. Bone pain – This is caused by the pressure of the tumor on the bone.

7. Weight loss – This is due to the tumor causing loss of appetite.

8. Lumps in the scrotum – This is due to the prostate gland being enlarged.

9. Sexual dysfunction – This is caused by the prostate gland being enlarged. It can also be caused by the tumors.

10. Fever – This is due to the spread of the cancer to the bones.

11. Fatigue – This is due to the cancer spreading to the lymph nodes and the liver.

12. Bleeding – This is due to the blood vessels becoming damaged by the tumors.

13. Pain in the pelvic area – This is due to the bone being broken by the tumors.

14. Urine retention – This is due to the enlargement of the prostate gland.

15. Back pain – This is due to the spinal cord being compressed by the tumors.

16. Loss of weight – This is due to the loss of appetite.

17. Weakness in the legs – This is due to the compression of the nerves that supply the legs.

18. Chest pain – This is due to tumors pressing on the ribs.

19. Numbness in the arms – This is due to the nerves being compressed.

20. Sudden weight loss – This is due to metastasis of the cancer to the liver.
