Patient Medication Information: uses, side effects, how to take - Bicalutamide Tablets
ABOUT THIS MEDICATION
What the medication is used for:
Bicalutamide Tablets are used in the treatment of advanced prostate cancer in combination with other drugs (LHRH analogues) which reduce the levels of androgens in the body or surgery.
What it does:
Androgens are male sex hormones within the body which can cause tumor growth within the prostate. Bicalutamide Tablets belong to a group of medicines called non-steroidal anti-androgens. This means that Bicalutamide Tablets interfere with some of the actions of androgens to prevent the tumor from growing.
What are the Stages of Prostate Cancer:
Localized disease - the early stages of disease
when prostate cancer is confined to the prostate gland.
Locally advanced disease - the disease
progresses and the cancer spreads to other tissues within the pelvis.
Advanced or metastatic disease - the disease
progresses to other parts of the body.
The PSA (Prostate Specific Antigen) test is a simple blood test for a protein produced by the prostate (PSA). This test has helped in the detection of prostate cancer resulting in an increase in the number of men whose prostate cancer is detected at an early stage.
What are the Treatment Options for Localized Prostate Cancer:
The optimal treatment for a given individual will depend on the specific circumstances of his case. For localized disease, patients are usually offered one of the following:
- Surgery to remove the prostate
- Targeted radiotherapy to kill the cancer cells in the prostate
No treatment initially (watchful waiting)
whereby the patient is monitored until there are signs of progression before treatment is started.
When it should not be used:
