Cancer

What is all about Cancer?

 It is quite common for certain types of healthy cells to divide or multiply themselves during the process of biological growth. Cell division is the primary activity responsible growth of an egg into embryo and later to a well-developed individual. Formation of different limbs or growth in height and size is the result of cell division. As long as cells give rise to new healthy cells, there would be nothing to worry about. If the growth of cells is abnormal at uncontrollable levels and the new cells turn out to be malignant, it results in a disease called cancer. Malignant cells further tend to grow in number and damage the neighboring tissue cells.

Mutation of cancerous cells:

The abnormal growth of malignant cells beyond control may be attributed to sudden change in genetic composition called “mutation”. The process of outgrowth may or may not cause in formation of mass and such a phenomenon is referred to as “neoplasm”. If the cells are benign and do not invade into adjoining tissues, then the outgrowth is not considered cancer, but is called a tumor. For a tumor to be considered as cancer, the cells in the tumor should be malignant and invasive.

Cancerous cells spread themselves through lymphatic network system or blood stream to other parts of the body. The invasion of malignant cells into the tissues of neighboring organs is called “metastasis”.  The growth and spread of cancerous cells follow an unconventional method and the cancerous cells have their own bizarre style of proliferation and invasion.

Cancer may happen to people of all ages starting from infants, kids, adolescents, adults and aged people. Any part of human body can be the target of the disease. Different types of cancer occur depending on the specificity of situations a human body undergoes. The symptoms of cancer differ with the specific category of cancer a patient suffers. The causes of cancer too depend on the different conditions a human is subjected to encounter. Certain types of cancer are passed on as a matter of heredity; and some others break out as a result of external,physical and unhygienic factors and pernicious substances/agents within the system, known as carcinogens.

Cancer can affect any part of human body. Based on the part of the body which has been attacked by cancer, the types of cancer can be enumerated as follows:

  • Breast cancer
  • Lung Cancer
  • Skin Cancer
  • Ovarian Cancer
  • Colon Cancer
  • Cervical Cancer
  • Liver Cancer
  • Thyroid Cancer
  • Lung Cancer Symptoms
  • Bladder Cancer
  • Stomach Cancer
  • Bone Cancer
  • Testicular Cancer
  • Throat Cancer
  • Brain Cancer
  • Mouth Cancer
  • Esophageal Cancer
  • Blood Cancer
