What are the common signs and symptoms
-
Prostate cancer may cause no signs or symptoms in its early stages. Prostate cancer that's more advanced may cause signs and symptoms such as:
- Frequent urination (especially at night)
- Weak urinary stream
- Inability to urinate
- Interruption of urinary stream
- Pain or burning sensation during urination
- Blood in the urine
- Bone pain
- Weight loss
- Loss of appetite
How is prostate cancer diagnosed?
- Digital rectal examination
- Prostate-Specific Antigen (PSA) test
- Transrectal Ultrasound Guidance (TRUS) and Biopsy
What are the different types of treatment?
Treatment depedns on the stage of cancer, as well as the general medical condition of the patient.
Surgery
A procedure called radical prostatectomy may be recommended if the tumour is localised at the prostrate. It involves the complete removal of the prostate.
Chemotherapy
Though uncommon, chemotherapy helps improve symptoms of prostate cancer if hormone therapy is ineffective.
Hormone Therapy
Hormonal therapy is commonly used to treat prostate cancer when it has spread or in combination with radiation therapy when the cancer is locally advanced or high risk.
Radiation Therapy
Radiation therapy uses high-energy targeted x-rays to treat cancer.
How is Radiation Therapy done?
Consultation
The Radiation Oncologist determines the most appropriate method and discusses with you the treatment intent, schedule, risks and side-effects.
Mark-Up and Simulation
A CT scan of the treatment area will be obtained, while three small full-stop size marks are made to ensure accurate positioning during your daily treatment.
Treatment Planning
A multidisciplinary team produces a customised treatment plan for you.
Treatment
Radiation therapy for prostate cancer is delivered daily (Mondays to Fridays) for about eight weeks. Each treatment session lasts 20 minutes.
Follow-Up
Your first follow-up appointment varies depending on how you do during treatment, and is usually about four to twelve weeks after you have completed the course of radiation therapy.
What are the types of radiation therapy available for prostate cancer?
3-Dimensional Conformal Radiation Therapy (3DCRT)
3DCRT delivers very precise doses of radiation to the prostate and spares surrounding normal tissue through a machine called a linear accelerator.
Intensity Modulated Radiation Therapy (IMRT)
IMRT involves varying (or modulating) the intensity of the radiation being delivered during treatment. Compared to 3DCRT, this technique can deliver more tightly focused radiation beams to cancerous tumours while reducing the amount n of radiation to surrounding healthy tissues.
High Dose Rate (HDR) Brachytherapy
HDR Brachytherapy is able to deliver extremely high doses of radiation therapy to tumours with minimal normal tissue effects through the use of Iridium-192 sources placed directly at the tumour site through the use of specialised applications.
