What is cancer?

Cancer is the general term used for diseases in which normal cells separate without any control thus involving other tissues. Cancer cells can also spread to various parts of the body through the blood and lymph system.



Wild cell growth turns into cancer when it is exposed to carcinogens (Cancer- causing substance) genetic defects, or viruses. A tumour is formed when cancer cells multiply large masses of tissue. In some cases tumours limit themselves to one spot in the body; some can be removed by surgery. These kinds of tumours may cause little harm and is termed benign. Hostile tumours are called malignant. The study of cancer is called oncology.



Causes of Cancer

People get lung cancer most of the time from smoking tobacco which is said to have carcinogenic substance mainly known as tobacco smoke. Some carcinogens include certain chemicals, the Sun’s ultraviolet light, and radiation. Cancer can be formed by several viruses by altering the DNA of a host cell and converting the cell’s normal genes into cancer – causing genes, or oncogenes. Genetic factors – such as chromosomal abnormalities or the inheritance of faulty genes from a parent of fore parent. This could most likely cause these persons who inherit these genes can end up having cancer. People that are Down syndrome, a chromosomal abnormality are susceptible to leukaemia.



How is cancer formed?

When a normal cell transforms into a cancer cell the genetic material (deoxyribonucleic acid or DNA) of a cell is changed, or mutated. Tumours don’t form over night they formed over decades or a certain amount of years, because of this it is very susceptible to formed into a cancer cell as time goes along. Most cancer occurs after the age of fifty, yet some are detected earlier in life, it varies.



Different types of cancer

It has been accessed that there are over more than 200 different types of cancers. They are named after the tissue or the organ they begin to form. The term Leukemia refers to cancer of white blood cells (can be also called leukocytes). Melanomas are cancers that begin in melanocytes (skin pigmentation.

Treatments for cancer

Oncologists have been using Chemotherapy, or drug therapy to help cancer patience around the world. When cancer spreads to different parts of the body chemotherapy is used to help treat the cancer, before it gets worst. The immune system is weak when cancer spreads through the body. Therefore a treatment name immune enhancing drugs or antibodies are also used to help build back up the immune system and to destroy abnormal cells. There has been an anticancer drug that kills cancer cells while leaving the good ones alive. This drug was introduced in the spring of 2001. The drug, Gleevec has proven to work very strongly against chronic myelogenous leukaemia, leukaemia is one of the four main types of blood cancer.



How can u prevent cancer?

Cancer can be prevented by doing the following:

¬For all smokers the only way that you can avoid yourself from getting lung cancer is to stop smoking.

¬Try not to be in the sun for lengthy periods, too much exposure to the sun can cause cancer

¬Lessen your high- fat diets

¬Avoid alcohol as much as possible

¬Unsafe sex

¬Other Carcinogens could prevent more than 80% of all cancer cases.

¬Do yearly testing; this would detect it in the early stage if you are tested positive, early treatment can be taken.



The following are various tests than can be taken to see if you have cancer.



Skin Cancer: Skin examination this is done by the naked eye of the doctor. If any area may look suspicious then biopsy is done and under the microscope cancer cells are examined



Prostate Cancer:

· Digital Rectal Examination: Prostrate is examined by a doctor using his/her finger from the lower part from the rectum. When you reach fifty years it must be done at least once a year. If there was any sign before that you may have prostrate then do a test once every year even though you may be under forty

Breast Cancer:

· Breast Self Examination: when you reach twenty years of age, this examination must be taken once every month.

· Clinical Breast Examination: the breasts and regions under the arms should be examined also, between the ages of 20 and 40 years. Once every three years this examination should be carried out, and once every year after the age of forty.

· Mammogram: Imaging of the breasts with X rays. It must be done once every year after 40 years of age.

An illustration of how a mammogram is done

Lung Cancer:

Chest X-ray: It is imaging of organs and bones in chest with X-ray. Especially if you are a smoker you should do chest x –rays at least twice a year.

Colorectal Cancer:

· Fecal Occult Blood Test: Blood in stool which can be seen only under microscope is examined. It must be done once every year after 50 years of age.
