What is Prostate Cancer?
The prostate gland is a walnut-sized gland situated below the urinary bladder. It produces semen and its development depends on testosterone, a male sex hormone. Prostate cancer develops when cells in the prostate gland undergo uncontrolled growth and become malignant, forming a lump and invading surrounding tissue such as the seminal vesicles and bladder neck. Prostate cancer is the third most common cancer among men in Singapore.*
Many elderly men are affected by small prostate cancers which do not cause any symptoms and are clinically insignificant. However, prostate cancer may spread through the lymphatic system to other parts of the body such as the lungs. It can also spread to lymph glands in the pelvis or to the backbone.
