Meningiomas can also grow on the exterior of the brain (or spinal cord). They push the brain away rather than growing from within it. Most are deemed benign as they grow quite slow meaning they have less potential to spread. Meningiomas that grow quickly and present with cancer-like behavior are called atypical meningiomas or anaplastic meningiomas, and are fortunately rare. Patients will exhibit different symptoms depending on the location of the meningioma. Imaging will be used to diagnose and locate the meningioma.
The decision on how to best treat a meningioma is multifactorial. Typically, surgeons may observe, surgically remove or recommend radiation therapy. Dr. Yashar will review all options with you and let you know his recommendation for treatment.
Pituitary tumors are growths that develop on the pituitary gland. Some pituitary tumors are the result of the presence of too many hormones that regulate important functions of your body. Some pituitary tumors can cause your pituitary gland to produce lower levels of hormones.
Most pituitary tumors are noncancerous (benign) growths. Some do not produce any symptoms at all. Pituitary tumors that produce hormones (calling functioning) can cause a variety of signs and symptoms depending on the hormone produced. The signs and symptoms of pituitary tumors that do not produce hormones (calling nonfunctioning) are related to their growth and the pressure they put on other structures.

There are various options for treating pituitary tumors, including removal, controlling its growth and medication management of hormone levels. Dr. Yashar may even recommend observation.
Schwannomas of the brain typically occur at the back of the skull between the pons and cerebellum on the vestibular nerve (8th cranial nerve) causing one-sided hearing loss and buzzing or ringing in the ear. Sometimes schwannomas will press on the facial nerve (7th cranial nerve) and in turn cause facial paralysis. The cause of schwannomas is still unknown however it is suggested that the gene that prevents tumors from forming is flawed. Complete resection of the tumor or even stereostatic radiosurgery may be recommended as treatment options.
Metastatic brain cancer occurs when cancerous cells from one part of the body spread to the brain, forming tumors. Symptoms of brain metastases vary and depend on the size and location of the tumor. These symptoms may include headaches, seizures, speech problems, comprehension problems, impaired vision, weakness or numbness in parts of the body and motor problems.
Brain metastases are diagnosed with imaging studies including mri and ct scan. The type of treatment rendered is multifactorial. It depends on the number of lesions, the location, the state of the patient’s systemic disease, and his or her overall health. Treatments for metastatic brain cancer include surgery, radiation therapy, and sometimes chemotherapy. These treatments may be done alone or in combination.
- I realized that Dr. Yashar genuinely cares to cure his patient with or without money, which makes him an exceptional doctor in a city that most physicians don't even listen to their patients, and all they do is to collect $ and ignore patients. At Dr. Yashar office I dealt with Amber and Michael who has been a credit to their profession and went above and beyond patient satisfaction.
