What is Cancer?
Cancer results when a cell within the body starts to divide and multiply in a way that is not consistent with the normal development of that cell type. Some cell development can be benign or non-threatening if the cellular growth is controlled and limited in development.
Malignant or cancerous growth occurs when normal cells revert to a more primitive developmental state and start to grow in an uncontrolled fashion within its original site. Tumors can arise from virtually all types of normal tissues. Usually the tumor cells will retain enough of the features of the original cell type to identify its origin.
Metastatic cancer occurs when cells from the original cancer site such as breast or lung cancer break off from the mass and are transferred to another part of the body. This transfer can occur through the blood stream, lymph nodes or direct seeding within a cavity such as the abdomen. These transferred cells can be trapped in the liver, brain and bone marrow and begin to grow there.
What Causes Cancer?
The cell changes that result in cancer development can occur from several sources:
- Hormonal changes in the body can be responsible the majority of some cancers such as breast, uterine and prostate cancers. Similarly, obesity can contribute to the occurrence of these cancers due to the additional hormone levels stored in excess body fat.
- Environmental factors such as chemical exposures, tobacco and alcohol use and can irritate the tissues of the lungs, mouth, esophagus and stomach. Many years of abuse can produce cell changes that can result in cancer.
- Viruses can directly or indirectly contribute to development of some cervical cancers, lymphomas and sarcomas.
- Genetic factors can play an important role in some cancers. Any family history of cancer should be mentioned to your family physician. He or she can then plan appropriate monitoring for ongoing individual healthcare.
- Radiation Exposure- There are many sources of radiant energy that can cause cancer including sunlight, artificial sources of UV light, x-rays, radioactive elements, and nuclear fission. Radiation exposure can create cell structure changes that result in development of malignant cells. These cell changes may be a direct result of the amount of exposure, with persons receiving greater amounts having a higher probability of disease. The most common cancer from this type of exposure is skin cancer and melanoma. These cancers are common to people who work outdoors or live in sunny areas without appropriate skin protection.
How is Cancer Treated?
Cancer is treated through three primary methods:
- Surgery - surgery can be used in tumors that are confined to a limited area. It is also very useful in obtaining accurate information regarding the extent of disease and staging information such tumor tissue for analysis and lymph node involvement.
- Radiation Therapy
