Cancer and its causes

cancer

It is an abnormal growth in the tissues of the cells of the body, which spreads in a fast and uncontrollable way, because it affects all members of the body, and usually the symptoms vary depending on the injured member, and the tissue, and it must be noted that it is spread in different areas of the body, Making it difficult to cure, and in this article we will inform you of its causes.

Causes of Cancer

The body usually suffers from cancer due to several reasons, including:

  • The presence of a genetic factor in the family, evidenced by the presence of a previous disease.
  • Exposure to certain substances and carcinogens, such as chemicals, radiation, and smoking.
  • Eat large amounts of alcoholic beverages.
  • Infection of a viral or bacterial infection such as hepatitis B infection.
  • Genetically modified genetic material may have two types. The first type is known as tumor genes, which are active genes in the cancer cell, and acquire many new characteristics, such as over-growth, recurrent division, and growth in unusual conditions. In the name of genes that inhibit the tumor, genes stop in the case of the cancer cell; because it opposes its composition, where correct any error in copies of DNA, watching the cell division, which contributes to the fusion of cells and prevent the movement, in addition to helping the immune system to protect the fabric.

Symptoms of cancer

  • Bleeding or abnormal gonorrhea from some areas of the body.
  • The appearance of a block in some areas of the body.
  • Change in color and size of mole.
  • Severe ulceration.
  • Yellowing in the color of the eye, or in the skin.
  • Blunt sound, and cough.
  • Difficulty swallowing, indigestion.
  • Liver hypertrophy.
  • Pain in the bones.
  • Inflammation of the lymph nodes.
  • Loss of appetite, weight.
  • Increase sweating in the body.
  • Feeling tired.

How to Diagnose Cancer

  • Laboratory blood test.
  • Computed tomography (CT).
  • Endoscopy.
  • Make a CT scan of the patient.
  • Take a biopsy of the disease.

Cure cancer

  • Surgical treatment: By removing the tumor, or by removing the affected organ if it can not be controlled.
  • Radiotherapy: Where it aims to reduce or kill the number of cancer cells.
  • Chemotherapy: Contributes to the killing and destruction of cancer cells.
  • Immunotherapy: Where it aims to stimulate the immune system in the body by the use of some types of drugs.
  • Hormonal therapy: This treatment contributes to the effect of hormones, by removing them, or disabling them.
  • Gene therapy: By placing the healthy gene in viral cover or in positively charged lipid particles, or by electrifying cancer cells, and forcing them to open pores to facilitate proper gene uptake in cancer cells.
