Cancer is a collective name given to a number of related diseases that cause the cells of the body to start multiplying without stopping.
This may sometimes spread to surrounding tissues that were not affected.
What is cancer and what causes it?
This is the question that many medical researchers have been trying to answer for a long time.
The genesis of cancer
Cancer is genetic; this means it is caused by variations in the genes that control cell growth, multiplication and function. Cancer is hereditary and can be passed down to other generations.
It can also result from body errors during cell division as a result of DNA mutation. Mutation can be caused by exposure to extreme environmental conditions such as chemicals and ultraviolet rays from the sun. The more the cancerous cells grow, the more they continue to mutate.
Types of cancer
There are over 100 types of cancer diseases.
They are usually categorized depending on the tissues or organs where they form.
For instance, if the cancer cells form in the brain then it is referred to as brain cancer.
Here are some of the cancer types that begin in specific cells.
Carcinoma: this is the most common type of cancer.
It is formed by epithelial cells that are found on the inner and outer surfaces of the body.
Sarcoma: this type of cancer is found in the bone and the soft tissues of the body.
The soft tissues include the muscles, blood vessels, tendons and ligaments.
Leukemia: this is the type of cancer that forms in the blood tissues of the bone marrow.
It is an abnormal type of cancer because it does not form tumors that are solid.
However, the number of white blood cells increases and destroys the other normal blood cells. This makes it difficult for the body to fight infections, absorb oxygen and control bleeding.
Lymphoma: as the name suggests, lymphoma is a type of cancer that begins in the lymphocytes.
These are disease-fighting cells that help in building a strong immune system.
It causes lymphocytes to build up abnormally in the various parts of the body.
The numbers of deaths that result from cancer every year have been on the rise worldwide.
A lot of research and technological ideas have been put in place to subvert the effects of this disease.
What is cancer and what causes it?
This question can only be answered after a lot of mysteries that surround this disease are solved.
Polio adversely affects the spinal cord and the nervous system.
It can lead to paralysis and muscle weakness.
The fact that polio can paralyze the body muscles that help you to breathe makes it a life threatening condition if not vaccinated against.
Polio vaccine helps to prevent this condition in both adults and children above the age of 6 weeks.
It works by exposing the patient to the virus making the body to develop immunity to the virus.
However, polio vaccine does not treat an active polio infection that is already developed in the body.
You should not receive polio vaccination if:
· You have ever received a life threatening reaction to vaccination that contains inactivated or polio virus,
· You are allergic to polymyxin B, streptomycin, neomycin, formaldehyde or 2-phenoxyethanol,
· you have severe or moderate fever illnesses
Also, do not receive the booster polio vaccine if you had a threatening reaction after the first shot.
To ensure that polio vaccine is safe for you inform the doctor if:
· Your immune system is weak due to a bone marrow transplant, cancer treatment or due to using certain medicines.
· You have a history of Guillain Barr syndrome
The side effects of polio vaccine
Just like most other vaccines, polio vaccine has side effects some of which are mild while other are severe and require emergency medical attention.
You should keep track of all the side effects that you may experience after receiving this vaccination.
Also, if you are receiving a booster dose, inform the doctor of any side effects that you may have experienced after the first shot.
If you experience any of the following allergic reaction get immediate medical help:
· Difficulty in breathing
· Swelling of the throat, tongue, lips or the entire face
· Frequent fainting
· Extreme drowsiness
· A high fever within a few hours after receiving the vaccination
· Seizure, convulsions or black out
The following are mild side effects of polio vaccinations that do not require emergency medication but you should inform the doctor if they persist:
· Body aches after the vaccination
· Joint pains
· Low fever
· Pain, redness or a lump at the point where the shot was given
· Mild fussiness or drowsiness
Being infected with the polio virus is more dangerous than dealing than receiving the vaccination to protect you against the virus.
The side effects of the vaccinations should not be a major concern as their effects are lower and they can be cured.
