The little prostate gland, shaped like a walnut, is located in a man’s pelvic. Prostate cancer develops when aberrant malignant cells congregate and expand to create tumours. It’s one of the most widespread cancers in men. It usually progresses slowly and, if found early, can be treated in various ways. Surgery or chemotherapy is not usually a necessary form of treatment.
The efficacy of radiation therapy for prostate cancer takes less time. When found and treated quickly, the disease is curable. More than 90% of instances are detected when they are still curable, increasing the likelihood that the tumours will react to the therapy. The disease may, however, be more aggressive in some instances and spread swiftly.
Adenocarcinomas, which come from the epithelial cells that produce semen, account for most cases of such cancers.
What is the process?
Radiation particles can damage cancerous cells’ DNA. The cells’ ability to divide is halted and may even perish due to this disruption.
Such a procedure eliminates all cancer symptoms and is considered a curative procedure. The usage is optional and may be combined with other treatments.
It can aid in managing the disease if it cannot be eradicated.
In the advanced phases of the condition, known as metastatic prostate cancer, it can help reduce symptoms. In that case, palliative care is the term used by doctors.
How effective it is:
Radiation therapy is comparable to surgery in terms of effectiveness for treating localised prostate cancer. The risk of the malignancy spreading is minimal with either treatment.
Radiation is frequently combined with chemotherapy, hormone therapy, or other therapies for men with advanced prostate cancer. By doing so, you may live longer and help control the spread of the disease.
It also effectively manages pain if the disease has reached the bone.
Various radiotherapy modalities:
It has two primary subgroups: brachytherapy and external beam radiation therapy (EBRT). They work in the following ways:
X-rays, gamma rays, or particles are directed into the tumour during EBRT from an external radiation source. Modern radiation oncology uses megavoltage linear accelerators (linacs), outfitted with equipment for precision X-ray photon shaping and tumour targeting. These machines are the most popular external sources today.
In brachytherapy, either transient or long-term radioactive sources are inserted into the tumour.
EBRT alone, brachytherapy only, or a blend of the two are all effective ways to treat prostate cancer.
How is advanced prostate cancer treated with radiotherapy?
If one is offered radiotherapy as part of their initial procedure for advanced prostate cancer, they will receive a form known as external beam radiotherapy.
One might have external beam radiation to the section of the body wherein cancer is producing issues to alleviate symptoms in regions where cancer has spread.
Some men experiencing bone pain may be administered a form of internal radiation to help them live longer and treat their bone pain if their cancer is causing it.
Side effects of this procedure:
Every medical procedure has the danger of potential adverse effects. A healthcare professional can handle any symptoms and help reduce these risks.
Radiation therapy’s more frequent adverse effects include:
- Urinary bladder inflammation
- Intestinal inflammation
- Urine with blood in it
- Higher chance of bone fractures
- A skin rash
Regardless of cancer’s form, doctors consider a patient to be “cured” when they are cancer-free for a predetermined amount of time after therapy. The more patients who manage to avoid developing cancer for five years, the more likely their condition will be cured.
Because of early diagnostic recommendations, technological improvements, and the efficacy of such therapy for prostate cancer, the disease has one of the best curability percentages of all malignancies. The five-year life expectancy is almost 100% when found in the initial local or regional phases when it hasn’t spread or has only expanded to a small number of pelvic regions.
