You have known that diseases are caused by deficiency of nutrients in the body. But there are various causal factors that lead to the development of diseases.
First, let us define the term "disease" together with its types.
A disease is a condition that interferes your normal bodily and daily functioning. It is a disorder of the various aspects of your life such as physical, physiological, psychological, and even your social state. It has a classification grouped into two broad categories as:
See the illustration below:
- They are characterized by progressive neuronal degeneration and loss in disease-specific regions. The disease arises without any clear inciting event in a patient without previous associated neurologic deficits. In most disorders, the etiology is unknown. The most common manifestations involve at least one of the following:
_ They are triggered when your body lacks the needed vitamins and minerals. Nutrients are essential for cell and tissue repair, production of cells, and healthy brain function. Apparently, these are not produced by your body on its own but by taking supplements, or eating foods with vitamins and minerals.
Two Kinds of Vitamins:
While more than 160 foods can cause allergic reactions in people with food allergies, the Food Allergen Labeling
and Consumer Protection Act (FALCPA) has identified the eight most common allergenic foods. These eight
foods account for 90 percent of food allergic reactions.
These eight, and any ingredient that contains protein derived from one or more of them, are designated as “major food allergens” by the FALCPA, which was passed by Congress in 2004 and became effective in 2006.
There are many risk factors for cancer: age, family history, viruses and bacteria, lifestyle (behaviors), and contact with (touching, eating,
drinking, or breathing) harmful substances.
Substances known to cause cancer are called carcinogens. Coming into contact with a carcinogen does not mean you will get cancer. It depends on what you were exposed to, how often you were exposed, and how much you were exposed to, among other things.
When does cancer begin?
The cell is the basic building block of all living things. All cells normally grow and divide (multiply) to replace old cells to keep the body healthy. A cell becomes cancerous when it grows quickly and uncontrollably. In most cancers, this process leads to the growth of tumors.
A tumor is an abnormal growth of tissue resulting from uncontrolled cell growth. Tumors are either benign or malignant. Benign tumors
are not cancer. Cells from benign tumors do not spread to other parts of the body. Benign tumors are not usually life threatening. Malignant tumors are cancer. Cancer cells can spread to other tissues and organs near the tumor. They can also spread to other sites in the body through the bloodstream or lymphatic system. This spreading is called metastasis.
