Summary Introduction
Introduction:
Cancer is the uncontrolled division or growth of the cells. Due to uncontrolled division, a mass of cells is formed, which is known as tumors. If tumor remains at their original site, they are called as benign tumor, and if they start migrating to a new site and affect nearby cells, they are known as malignant tumor.

Although cancer is not a contagious disease in humans or other vertebrates, there have been rare cases in which cancers have spread from one organism to another.

- In the process of metastasis, cancer cells break away from where they first formed (primary tumour) and travel through blood or lymph system to other parts in body. This is how secondary cancers, called metastatic cancers, are formed. The spread of cancer can happen early or later in its development. When it spreads earlier, it might not have grown into a size that can be noticed yet. What tests (two tests) would you do to diagnose the metastatic cancer and track its point of origin? origin?arrow_forwardCan you explain the following? about the disease process of lung cancer Cigarette use, exposure to carcinogens, such as tobacco smoke, also in environmental pollutants, such as asbestos, radon, and industrial chemicals, or genetic predisposition. Induces genetic mutation in the DNA of lung cells, leading to initiation of the cancerous process. Expansion of mutated cells. Mutated cells begin to grow and divide uncontrollably forming abnormal cells known as tumors. Tumors can be classified as small cell lung cancer (SCLC) or non-small cell lung cancer (NSCLC). Tumor invades nearby tissues (Lung tissue, blood vessels, and lymph nodes.) Cause structural damage. Cancer cells break away from the primary tumor and travel through bloodstream or lymphatic system to the parts of the body. (Common sites of metastasis liver, bones, brain and lung tissues. Tumor stimulates the formation of new blood vessels to supply it with nutrients and oxygen, supporting its continued growth.

FACT: New research reveals that the tumor has a purpose. Andreas Moritz, in Cancer is NOT a disease – It’s a survival mechanism, explains that cancer is a response to internal toxicity. Cancer is how the body tries to keep us alive when we are in danger of imminent death from poison; cancer cells feed off our toxic buildup. Only by addressing the cause of the tumor can we have a real cure. The tumor is so important to the body that it is supplied with special blood vessels. Why would the body try to destroy itself? It makes more sense that the tumor is serving a purpose.arrow_forward

Regardless of how they become cancerous, the same general pattern is followed. Put the steps of cancer development in order from first to last. 1. A cell begins to grow and divide uncontrollably.2. The cell metastasizes and moves through the bloodstream, spreading throughout the body.3. Part of the tumor breaks off and is now malignant.4. The benign tumor is confined to one place.5.
