Cancer is known as the most deadly disease. Stage four means the cancer has progressed far along. What are the characteristics of this stage? How can it be diagnosed and treated? How long is someone in stage 4 supposed to live?
As mentioned above, every cancer stage has its own characteristics that are different from those in other stages. These are the characteristics of this stage:
The symptoms at this level are stated according to their location in the body. Stage 4 brain cancer symptoms are:
Although most brain cancers fall under stage 4 cancer, it is important to classify them as they ought to be. More on the types of cancer is that they are classified depending on the origin of the tumor. According to (WHO) World Health Organization, there are 9 types of brain cancer but will only discuss a few here. Some of these cancers are:
This is a type of cancer in young children and infants. It usually appears in that part of the brain that contains cerebrospinal fluid.
This is the second type of brain cancer. This cancer originates from the cerebral hemisphere and takes about 12% of all the brain cancers. This cancer originates from astrocytes. Astrocytes are types of brain cells.
This is another type of brain cancer found in children. It originates in the cerebellum before spreading to other parts of the body.
This type of cancer occurs in the pineal gland. This refers to the pine shaped gland in the vertebrae part of the brain.
In order to determine the chances for survival of a cancer patient, it is important to understand the type of cancer they have. This is because there are different factors that determine life expectancy. Some of the factors that determine survival rate as follows:
Depending on the stage of the tumor, life expectancy is anywhere from a few months to five years.
Stage 4 brain cancer spreads at a very high rate, treatment begins immediately after diagnosis. Surgery, radiation and chemotherapy are examples of cancer treatments at stage 4. It is only after a scan is done that the doctor progresses with the treatment. A biopsy is also helpful in analyzing tumors.
This is where doctors try to remove all the tumors in the brain. They open the skull and remove all the visible tumors without damaging any tissues in the brain.
Patients receive chemotherapy after either 2 or 3 weeks of surgery. During chemotherapy, more than one type of drug is used to destroy the cancer cells. This is not the case in radiation. This is because radiation uses ions and not drugs. It is these ions that target the tumor for destruction.
A brain tumor is the uncontrolled growth of damaged cells in the brain. This growth also spreads to the spinal column causing more harm to the body. Below is a table detailing the stages, besides stage 4 brain cancer:
|
Stage zero |
This is the stage where the cancer has only developed in layers on a particular cell. It is the early stages of brain cancer. |
|
Stage one |
Although the cells are already infected, they appear normal. This is because it is hard to see the cancer cells at this stage. The good thing about the cancer in this stage is that it can be cured. Surgery is the most preferred method of treating stage 1 cancer. |
|
Stage two |
Although the cancer cells are growing at a very high rate in this stage, the cancer is still curable or could be treated. Apparently, chances are that cancer is bound to return even after treatment. This is because it has already spread to most tissues in the body and thus hard to clear. |
|
Stage three |
In this stage, the already damaged cells are growing rapidly. Besides spreading in the brain, these cells begin to spread to other tissues in the body |
|
Stage four (metastasis) |
This is the scariest cancer stage. This is because the disease has already spread to almost all parts of the body and chances of curing it are low. In other words, it is hard to treat stage 4 cancer. |
