It is a condition wherein cells mutate and increase number, with changes in their morphology and without any function. Cancer cells infiltrate normal and healthy tissue and they compete with normal cells for sustenance from the blood. Malignant cells compress and kill healthy tissue and deprive them of nutrition.

In the long run, cancer cells cause cellular malignancy, nutritional deficiencies, and ultimately, death.

Cancer is the second leading cause of death according to the Centers for Disease Control and Prevention. Cancer is a poorly understood disease that robs its victims of proper functioning, the ability to perform activities of daily living, and more often than not, brings significant depression.

Causes Any cell in the body has the potential to mutate and become a cancer cell. However, a healthy immune system is able to kill these cells before they can cause any aberration in the body. The etiology of cancer is unknown and anything that has the potential to cause cellular DNA mutation has the capacity to cause Epithelial tissue chart.

The etiology varies across the specific types of cancer on virtually all cells of the body.


Some of these include: Genetics Some genes carry a code for the transcription of cancer and malignancy. It is unclear; however, what causes these genes to cause malignancy. Certain extrinsic triggers may contribute to their activation.

One thing is sure though, cancer runs in the family. Genetic Screening may detect presence of these oncogenes. Tobacco Cigarettes contain hundreds of carcinogens and other harmful chemicals.

It has been clearly shown through various studies that cigarette smoke, even second-hand smoke increases the risk of cancers of the lungs, oral cavity, lips, esophagus, and larynx. Smokers who inhale the smoke have an increased risk for lung cancer as the smoke reaches the lungs.

Diet It has been noted in studies that a diet high in nitrates processed foodsbenzopyrenes grilled foodsalcohol, red meat and fat increases cancer risk. Also, a diet low in vegetables and other greens significantly increase the risk for colon cancer.

Physical Activity A sedentary lifestyle contributes to the development of cancer as much as obesity. It is important to control your weight too.

It is recommended to have at least minutes of non-vigorous, or 75 minutes of vigorous exercise per week. Sun and UV Exposure Sunlight and the Ultraviolet radiation it carries significantly increases cancer risk and risks for melanomas.

Ultraviolet light alters the DNA of cells and this causes malignancies if not controlled by the immune system. Other Carcinogens Carcinogens, certain drugs, viruses, chemicals, pollution, and certain infectious agents all have the potential to cause malignancy.

It is important to live in a clean environment to be able to avoid these triggers. Pathophysiology Symptoms Cancer symptoms depend on the severity and specific type of cancer. Most cancers however are asymptomatic and will only produces signs once they are at advances stages.

Early detection and treatment is the key to cancer survival. There are many symptoms of cancer but some of the potentially-serious warning signs are:Bio-Energetic Frequency Chart I [Editor's Note 1: This is one of many possible frequency lists that can be used with the NCH Tone Generator.

It is incredible that the body is made up of these that make every systems function at their best. The study of the human body made us understand how amazing it is and it is up to us to maintain it. Click the button below to add the Wall Chart - Epithelial Tissue to your wish list.

Epithelial Tissue. Epithelial tissue is a sheet of cells that covers a body surface or lines a body cavity. Two forms occur in the human body: Covering and lining epithelium– forms the outer layer of the skin; lines open cavities of the digestive and respiratory systems; covers the walls of organs of the closed ventral body cavity.; Glandular epithelium– .
