Leukemia is known as a type of cancer that attacks the blood. A recent
discovered protein is believed to provide insights into the details of
the interaction between sperm and egg. Its structure is believed to
hold the key to new treatments for the earlier mentioned condition,
leukemia. This protein structure was discovered by C.D. Stout at the
Scripps Research Institute in La Jolla, California.
Treating leukemia can be a complex and difficult task. Certain factors
must be taken in to calculation if a proper treatment is to be
administered and to take affect. The treatment varies from person to
person depending on their state of health, immune system and many other
facts. Also the appropriate treatment must chosen for each type of
leukemia. Other factors like the severity of the disease or precedent
treatments must also be taken in to consideration.
The blood cancer called leukemia, begins in the bone marrow and the
lymph system, the two organs that make blood.In leukemia,these two
organs produce abnormal and immature white blood cells,which are called
leukocytes.
The stem cells are formed by the leukemia cells in the bone
marrow.These cells have uncontrolled growth and lead to decrease
production of normal blood cells.From this point of view the symptoms
are:anemia, increased risk of bleeding which include bleeding gums,
nosebleeds, bruising, increased risk of infection, slow healing.
Leukemia is a very serious disease that affects both the marrow and
blood system. In the case of leukemia the number of white blood cells
that are in a human body get seriously out of control and multiply to a
very big and alarming number. Because of this, and the fact that the
marrow is responsible for normal blood production, the space for the
normal count of blood cells to be made is messed up. From this 3 major
problems occur: either the white blood cells become to rare the risk of
infection seriously rising in this case, the red cells also become to
be more rare, in this case anemia, fatigue or weakness affecting the
patient.
Looking behind the FDA curtain
Thank you for all the comments to my blog postings about the FDA and
its process for reviewing Genasense. It’s still up to the FDA to
approve it or not. It is an uphill battle as the advisory committee
voted 7-3 against approval. The earlier blog posting and the very
expert comments from so many CLL’ers will provide you with a all the
background if you are new to the discussion.
Who is the FDA trying to protect?
I’ll be the first to say the folks at the FDA have a hard job. It is
their responsibility to protect the public safety and certainly not
subject those of us who are ill to drugs that offer false hope or
tremendous risk. And when it comes to considering new drugs for
approval, I know how much they want to get it right the first time. The
last thing they need is to have to pull a drug off the market after
people have been hurt causing damage to the FDA’s credibility to
Congress.
The
most dangerous feature of leukemia is that is attacks the blood which
then has access to all of the bodies other organs, including the all
brain, heart, kidneys and liver. Thus, the cancerous cells are spread
throughout the body by the very blood that is normally the key to good
health, in a leukemia sufferer.
Leukemia is a malignant cancer that first affects the organs that
produce blood and blood cells,like the lymph and the bone marrow. These
organs loose control over the number and quality of white blood cells
(also known as leukocytes) that they produce, so the blood gets
saturated with with abnormal white blood cells that can't fulfill their
initial role of protecting the body against viruses and bacteria.
Being a cancer of the blood cells, leukemia has several types,
classified depending on how quickly they progress and what cells they
affect.We can mention the role of normal blood cells. White blood cells
are fighting against the infections, red blood cells carry oxygen from
the lungs to the rest of the body and return carbon dioxide to the
lungs as waste but also give the red color to the blood, and platelets
form clots to control bleeding. The blood also contains a fluid called
plasma.The bone marrow, which is a spongy area located in the center of
bones is responsible with the producing of these products.
Leukemia has two major types: acute and chronic. In what concerns acute
leukemia, there are two forms: if leukemia involves lymphocytes, we are
dealing with acute lymphoblastic leukemia, and if it involves myeloid
cells, is called acute myelogenous leukemia. Depending on the
particular cell that has become malignant, there can be many different
types of acute lymphoblastic leukemia and acute myelogenous leukemia.
Leukemia is a disease that is considered to be life-threatening. It
requires prompt intervention when discovered, in order to maximize the
chances of recovering through specific treatment and therapy. Leukemia
is basically a type of cancer of the bone marrow and blood, caused by
inappropriate cellular activity.
Leukemia is a form of cancer that occurs at the level of the spinal
marrow. Inside the spinal marrow there is a type of immature blood
cells that are called stem cells. These cells have a neutral initial
state and later develop into different types of blood cells (white
blood cells, red blood cells and platelets).
Scientists and doctors, with the help of modern technology and state of
the art technical equipment, have succeeded in finding somewhat of a
cure for leukemia. Pharmaceutical companies have come up with Gleevec,
a promising new oral treatment for chronic myeloid leukemia suffering
patients.
A doctor- a pathologist or a hematologist/oncologist- having special
training in recognizing cells from blood and lymphoid tissue diseases
will examine under the microscope all bone marrow aspirates and biopsy
specimens, all lymph node biopsy specimens, all CSF specimens, and any
blood smears with significant abnormalities.After cells from a sample
are placed on glass microscope slides, there can follow the
cytochemistry. The cells are stained with dyes that are attracted to
certain chemicals that are present only in some types of leukemia cells.
People with leukemia which, is a blood cancer,may have different
symptoms.So the symptoms can be common,chronic and acute.Generally
these symptoms are not considered sings of leukemia because it can be
an infection or another problem which can cause these symptoms.
In the case of leukemia signs and symptoms are also many and variable.
One of the most important would be the infections that appear and
trouble the patient by making him go down with a fever. Because the
white blood cells have gone out of control and damaged the other blood
cells, organs begin to be attacked by microbes and viruses determining
the appearance of fever in that person.
