Brain metastases from systemic cancer are the most common type of intracranial neoplasm in adults, being almost 10 times more common than primary malignant brain tumors, which cause a significant burden on the management of patients with advanced cancer (1). The lungs represent one of the most frequent sources of metastases to the brain, with a probability of (36–64%) (3). Symptoms suffered by the patients include headaches, epilepsy, focal weakness, numbness or changes in mental status. The prognosis of patients with brain metastases is not optimistic and the median survival time is ∼1–2 months if left untreated. The 1-year survival rate has been recorded as 10.4% (4,5). The treatment of metastatic brain tumors is complex; not only due to being able to provide local control and improve neurological function, but also due to factors such as age, performance and systemic disease status and the size, volume, location and number of metastases at presentation
CyberKnife is a robotic radiosurgery system with a linear particle accelerator (linac), which is coupled with real-time imaging to track and compensate for the patient’s or target’s motion. As a relatively non-invasive treatment modality, CyberKnife demonstrates certain benefits, including a more accurate target localization and improved dose delivery for the management of metastatic brain tumors that allows higher biologically effective dose delivery without increased incidence of toxicity.
In the present case, the results for the treatment of multiple brain metastases after CyberKnife surgery with a 7–8 Gy marginal dose was promising. CyberKnife for metastatic brain tumors is an effective and safe method for reducing the marginal dose prescribed for multiple brain metastases and for minimizing the radiation-related neurotoxicities. In conclusion, CyberKnife, a focused, highly-targeted radiosurgery and fractionated radiotherapy is particularly useful for multiple brain metastases. CyberKnife provides the advantage of the management of local recurrence and a tolerable complication rate. Although the treatment of brain metastases has been performed with CyberKnife, the clinical significance and optimal dose fractionation scheme require further investigation.

What menstrual problems are to women, prostate problems are to men. The prostate is a gland in the lower abdomen that aids in the production of semen. The prostate is walnut sized in a young man, but can get enlarged with age. As it grows bigger, it can cause a number of problems. These are commonly seen after a man celebrates his 50th birthday.
There are three common prostate problems faced by men. Some of the symptoms that can tell if a man has a prostate problem are:
This can be defined as inflammation of the prostate gland. In most cases the cause of this inflammation is unknown. However, there are two types of prostatitis; bacterial and nonbacterial. While the former reacts well to antibiotics, the latter is more difficult to control. Symptoms of this disease vary from one person to the next. Some of the factors that could trigger this disease are:
As mentioned earlier, as men get older, the prostate gland tends to grow in size. This growth is benign, but can block the bladder neck and prostatic urethra. This can cause problems urinating and lead to acute urinary retention. This can be very painful. Inserting a catheter can provide temporary relief and help release stored urine. Chronic retention is much less common and is associated with high bladder pressure and can damage the kidneys.
Advancing age and family genetic history are said to be the main triggers of prostate cancer. This type of cancer can remain restricted to the prostate gland in its early stages but may spread to the other glands as the cancer advances. This can also cause the growth of secondary tumors in the bones.
The only way to correctly diagnose a prostate problem is with a thorough physical examination. This includes a digital rectal exam where the doctor will insert a gloved finger into your rectum to check the size of your prostate, a blood test, mid stream urine tests and ultrasounds. In some cases a biopsy of the prostate may also be required. Depending on the diagnosis, your doctor may prescribe antibiotics, surgery, radiotherapy or hormone therapy to manage your prostate. If you wish to discuss about any specific problem, you can consult a Urologist.
