Brain cancer is a disease of the brain where cancer cells (malignant) grow in the brain tissue. Cancer cells grow to form a mass of cancer tissue (tumor) that interferes with brain tissue functions such as muscle control, sensation, memory, and other normal body functions. Tumors composed of cancer cells are called malignant tumors, and those composed of noncancerous cells are called benign tumors.
We all know the function of brain. It is the main control center of our body that monitors/instructs everything thing in our body. Any disease that affects this central control system is really a big problem. And the worst thing to happen is brain cancer. Brain cancer is the development of brain tumors i.e. tumors in the brain. These could either be benign or malignant; the latter being the really harmful one.
Types of brain cancer
As most other types of cancer, brain cancer is also classified as primary brain cancer and secondary brain cancer. Primary brain cancer is the one that originates from the brain itself i.e. that originates in the brain cells. Secondary brain cancers is the one that doesn’t originate from the brain cells but is instead passed on from another organ/ part of the body
Symptoms of brain cancer include headaches that are worse in the morning, changes in personality, abnormal eye movements, and weakness in the arms and legs. Seizures, nausea, and drowsiness are other symptoms of brain cancer.
Let’s face it. Brain cancer is scary. Since the brain is the nerve center of the human body, brain cancer conjures up images of a mind disintegrating, along with the mobility and other functions of the body. There are essentially two types of brain cancer: cancer that starts in an organ such as the kidney or lung and makes its way to the brain (metastatic brain cancer), and cancer that starts in the brain and filters down to other organs (primary brain cancer).
Symptoms of brain cancer include personality changes, stress, aggression, shyness, or depression. They are also appetite changes, lethargy, lameness, muscle twitches, eye and facial issues, coordination problems, bleeding in the nasal cavity, respiratory issues, and heart problems. The early symptoms are usually related to the appetite, weight loss, and personality changes. As the brain cancer progresses you will see more changes and of course extremely muscle weakness. The brain is the center for all things in the body.
Chemotherapy is the administration of a powerful drug or a combination of such drugs to kill tumor cells. Chemotherapy is normally done in 2 to 4 cycles of treatment, each cycle consisting of a short period of intense medication with enough rest and recovery period after that.
How to treat brain tumors depends on the age of the patient, the stage of the disease, the type and location of the tumor, and whether the cancer is a primary tumor or metastases. Brain cancer are somewhat unique because of the blood brain barrier, which severely restricts the types of substances in the bloodstream that are allowed by the body into the brain and makes drug treatment extremely difficult. Because of this more and more research is being undertaken in delivering medication by means of nanoparticles, amongst the properties of nanoparticles that make them ideal candidates for recognizing and treating tumors, their ability to deliver a wide variety of payloads across the blood-brain barrier is perhaps the most important.
Causes of brain cancer
As is the case with many other types of cancer, the causes of brain cancer is a big topic for researchers. However, certain genetic conditions and exposure of head to radiation (as received during radiotherapy as part of treatment of other conditions) are known to be causes of cancer. There are a number of other theories that keep coming up time and again, each suggesting different possible causes of brain tumor (one famous one is about mobile phones causing brain cancer). However, there really isn’t a very convincing theory about what causes brain cancer.
Brain cancer survival statistics for the deadliest of tumors such as gliomas have not improved significantly over the past two decades and the clinical armamentarium is, to a large extent, still dependent on surgery and radiation therapy, treatments known to leave survivors with devastating cognitive deficits. Gamma knife surgery is a radiosurgery technique used to treat people with brain cancer and other neurological disorders
A sign is also an indication that something is not right in the body. But signs are defined as things that can be seen by a doctor, nurse, or other health care professional. Fever, rapid breathing rate, and abnormal breathing sounds heard through a stethoscope may be signs of pneumonia.
