The definition of cancer is defined as the continuous uncontrollable growth of an abnormal cell. These cells are called malignant cells or cancerous cells. Cancerous cells not only have the ability to rapidly multiply, these cells also migrate to other parts of the body. Cancer is not just a single disease, but a group of diseases that can lead to not just a loss of limb or sight or other body parts. It’s a very serious medical condition than can lead to death if the spread of these malignant cells are not controlled, destroyed and removed at an early stage.
Some cancers may be curable when detected and treated early. The stages of cancers are 0, I, II, III, and IV.
Stage 0 refers to the very early form of cancer development. This is where abnormal cells or potential cancerous cells had been detected developing in a layer of normal cells (epithelium) also known as the principal site. Blood testing for cancer detection can help find out if you are developing cancer during this stage.
Stage I is when the cancerous cells are localized to one part or area of the body. The size and growth of the cancerous cells is very small. During this stage the cancerous cells have not developed from the principal site. Surgically removing the cancerous cells can be done during this stage.
Stage II is when the cancerous cells are detected not just in the principal site, but is now in an area or region of the body too. Their size and numbers during this stage may have increased and might have spread to organs, lymph nodes and tissues close by. Right treatments could still slow down their growth and spread during this stage.
Stage III is when the cancerous cells are larger or their numbers have multiplied considerably. During this stage the cancerous cells had already spread to other organs and body parts close by, or even to farther lymph nodes, and organs or tissues.
Stage IV is when the cancerous cells has metastasized or gave birth to secondary tumor and spread to other organs or parts of the body. Drugs are given to patients to at least somehow ease their pain. Nevertheless, the possibility of death is very likely during this stage. There’s a very slim chance of surviving this stage.
Cancer is one of the leading causes of deaths around the world. Cancer strikes anyone. Most cases are seen on adults but children are sometimes not spared.
Some of the most common cancers are breast cancer, colon cancer, ovarian or cervical cancer, bone cancer, skin cancer, brain cancers, lung cancer, liver cancer, kidney cancer, prostate cancer, and cancer of the pancreas. These cancers are caused by solid tumor. Leukemia and lymphoma/Hodgkin’s disease are cancers of the blood.
The definition of cancer means a disease of the genes. A gene is a part of the molecule called Deoxyribonucleic acid or DNA. Genes produce proteins through RNA or Ribonucleic acid. These proteins feed the cell to grow and divide and to develop or determine our shapes, forms and sizes. A disruption or mutation of the DNA can cause the genes to go haywire and produce defective proteins. This is where the cell begins to mutate and starts growing to become a tumor or cancer cell.
Hereditary, excessive alcohol drinking, excessive smoking, pollutants, sexual behavior, diet, weight, over exposure to the Sun’s UV light, and environment are some of the risk factors for cancers.
Prevention is still better than cure. Some things that you can do to slim down the chances of you having cancer are – avoiding too much weight gain by exercising everyday for at least 30 minutes to one hour, not smoking and avoiding second hand smoke, avoiding the sun during hours when it’s strongest, not eating too much fatty food, not drinking excessively, eating plenty of green leafy vegetables and fruits, and avoiding promiscuous sex.
There are several treatments for cancers, but they are very expensive, even painful and sometimes they just don’t work. For the families of those who didn’t survive this dreaded disease, the definition of cancer for them is simple. Death!
