Cancer - How the Body Cures Cancer
Cancer is a disease that has no cure. However, with proper treatment, many types of cancer can be prevented from spreading. The spread of cancer is mainly dependent on where the cancer cells originated from. Here, we will take a look at how cancer spreads.
Cancer cells initially travel to the tissues, bones, and organs to divide and grow. However, if cancer cells spread to other areas of the body, then it is known as metastasis. This is how a form of skin cancer, known as melanoma, can metastasize to different areas of the body. For example, a malignant melanoma that originated from the liver can spread to the chest, stomach, and even to the abdominal organs. Although melanoma is not a very serious condition, it can eventually lead to a fatal form of cancer called melanocytic melanoma.
Cancer is divided into two categories. There is the primary tumor or cancerous tissue and then there are the non-tumorized tissues. Tumor or cancerous tissue grows and spreads rapidly in the body while non-tumorized tissue or normal cells grow and reproduce at a slow rate. Tumors can cause life threatening effects and are therefore major concerns for cancer patients. Non-tumorized cells, however, can also spread throughout the body without causing any harm.
Cancer that spreads to the lymphatic system or organs like the bladder, pancreas, or colon is referred to as distant metastatic cancer. Cancer that spreads to the bones, muscles, or tissues found in the mouth, esophagus, or vagina is known as close metastatic cancer. Cancer that spreads to the lung or lungs is referred to as central metastatic cancer. Cancer that spreads to the lymph nodes or blood vessels in the body is called lymphatic cancer.
Malignant mesothelioma is a disease that starts in the lungs and then spreads throughout the body. It is caused by asbestos exposure. Other rare forms of mesothelioma include pleural mesothelioma, peritoneal mesothelioma, pericardial mesothelioma, and periculohumeral mesothelioma. Cancer that spreads to the liver is called carcinoma of the liver.
سرطان starts with the mutation of cells. As the mutation progresses, the number of cells that grow and multiply increases. When the number of cells grow exponentially, this is called tumor growth. The rate of cell mutation is the reason why cancer spreads so rapidly in the body.
Cancer can also spread through the blood. The most common site of cancer spread through the bloodstream is in the lungs. Cancer cells are able to travel to the lungs from other parts of the body. Other sites of cancer spreading through the blood include the breast, ovarian, intestinal, and abdominal areas. The colon is another common site for cancer spreads. Cancer cells are often found in the bone marrow.
Cancer spreads through the mechanism of metastasis. This means the tumor cells move from their original site to other locations in the body. Metastases can occur in two different ways. They can be via direct contact such as when a tumor biopsies its surrounding skin cells or hair follicles; or they can be spread via an indirect route such as by means of a lymph fluid exchange. An indirect route of metastasis can be a common site for cancer to spread, particularly because the cancer cells can become encapsulated within a benign tumor. When a tumor and a benign tumor form one large mass, known as a malignant melanoma, it is called a primary tumor.
