There is no denying the fact that cancer is a disease that commands loads of shock, fear and stress in the popular perception. Strictly speaking, cancer is not a new disease. However, in the recent times, the incidence of cancer has been on the rise (Dein, 2006, p. 35). …

However, in the recent times, the incidence of cancer has been on the rise (Dein, 2006, p. 35). There are various dietary, genetic, lifestyle related and environmental factors that could cause cancer (Dein, 2006, p. 35). Medical experts associate this trend with a range of factors such as pollution, smoking, stress, improper dietary choices, faulty lifestyles, substance abuse, genetics and the like, which negatively influence the cell division mechanisms in the body and lead to cancerous tumors in different human organs (Dein, 2006, p. 35). To put it in simple words, cancer happens to be an uncontrolled division of cells in an organism’s body (Weinberg, 1999, p. 1). In a healthy individual the division of body cells is systematic and controlled and facilitates many important body functions and physiological developments. However, in case this cell division gets uncontrolled, it may form a tumor, the name attributed to a mass of abnormal cells (Weinberg, 1999, p. 1). As cancerous tumors are composed of abnormal cells, they do not serve any healthy function in an organism’s body. Rather, an unobstructed growth of cancerous tumors obstructs the normal working of the healthy tissues and in extreme cases, if not checked through medical intervention, may cause death (Weinberg, 1999, p. 1). Cancers are caused by a variety of reasons or factors. They may infect any part or tissue in a body. Many a time cancers are caused by genetic disorders (Adrouny, 2002, p. 7).

Malignant tumor is divided into metastasis tumors and benign tumors. Cancer may spread to other body parts through blood or lymphatic system. Most abnormal cells and cancers are identified by the tissue from their normal cells originated, for example, lung cancer, breast cancer and colon cancer.
Cancer impacts the physiology as well as psychology of the patients and their families to a large extent. The present discourse evaluates few causes of these commonly occurring cancers and their effects on the patients. Lung cancer is caused by excessive smoking.
Another way that healthy cells differ from cancer cells is that healthy white blood cells can detect damaged cells, such as viruses, and attack them, stopping them before they spread the virus to the rest of the body. Cancer cells, however, can pass through this system without being detected, which means that the immune system is not notified to their presence (Skehan 15).
Introduction: Cancer can be described as an uncontrolled multiplication of cells in a given organ or tissue. Normal cells follow a general pattern of division, which is termed as mitosis or meiosis. Due to environmental, chemical, or genetic factors, these cells begin to behave in an abnormal manner by repeated division.
Cells are naturally designed to multiply in a controllable manner, failure to which a cancer may develop. The uncontrolled cell multiplication can be attributed to mutation of genes (a molecular unit in our DNA, which contains information of how cells operate).
Thyroid gland possesses two lobes, left and right. Thyroid gland is an endocrine gland that produces hormone called as thyroid hormone, utilizing iodine in the process of synthesis. Thyroid hormone is known to regulate body metabolism and therefore plays a crucial role in the development process.
The number of deaths due to these illnesses keeps on growing annually all over the world. Why is this so The only answer that scientists could come up with is that because medicine still cannot point out the main causes of cancer and its proliferation in the body, resulting to unavailability of means to combat it.
Cancer has been a part of the human condition since recorded history. The earliest evidence of cancer is found among fossilized bone tumors, human mummies and manuscripts in ancient Egypt, dating to about 3000 B.C. The cause of cancer was variously attributed to the Gods,
This means modifications in eating, cessation of smoking, and moderate physical activity. Such changes prove to be very useful in the early stages of cancer when it is most treatable. ACS services like
