Cancer Killing Cap
Every year close to 41,000 people are told that they have a brain tumor, primarily in adults. A brain tumor is a mass of abnormal cells in the brain. Some can be benign or malignant. Treatment options depend on the type of brain tumor, size, and location. Symptoms will also depend on size, location, and the rate it grows. Generic symptoms can include: new onset in headache patterns, hearing problems, headaches that become more severe and frequent, seizures, vision problems, behavior changes, gradual loss of movement in arms or legs, confusion in everyday tasks, and speech difficulties.
Current treatment includes surgery, radiation therapy, and chemotherapy. How the patient is treated depends on the size, type, and location of the tumor. Surgery is usually needed for most primary brain tumors. Some tumors can be removed completely, but for the ones that are too deep or that enter brain tissue have to just be reduced in size. Brain tumors usually require more than just surgery because the surrounding tissue can become invaded.
For tumors that are more aggressive, like Glioblastoma, researchers are developing a new innovative way to combat them. In the past, electric fields were considered to cause cancer. Now they are using low-intensity, intermediate-frequency electric fields to fight brain tumors. It pinpoints tumors without surgery. Clinical studies have found that it can more than double survival rates. In a study performed by a biotech company in Israel, researchers glued four sets of electrodes on the scalp of 10 patients with Glioblastoma. They wore it on their heads 24 hours for 18 months. For eight people, the new approach increased their life expectancy. The tumors stopped growing in four patients and shrank in the other four. In one patient, the tumor disappeared and has remained tumor free for 2.5 years; the patient went into the study with a six month survival time. The device is called TT Fields cap. It is ideal for patients with Glioblastoma because tumor cells in the brain divide frequently and normal brain cells remain unaffected by the electric fields. A current study that involves more than 200 Glioblastoma patients in the U.S. and Europe is in a phase III trial. If it is successful, then the electric field therapy can be tested on other dangerous cancers, like breast cancer and progressive cancer.
