Types of Cancer
Almost one in three people will develop some type of cancer in their lifetime. It is the second leading cause of death worldwide. It affects both individuals and communities. The burden of cancer imposes tremendous strain on families and communities, especially in low- and middle-income countries. Nevertheless, survival rates are increasing in countries that have strong health systems.
Cancer can affect any part of the body. Cancer cells move through the bloodstream and lymphatic system. They may also travel to distant organs and tissues. Some cancers are inherited. Others are the result of exposure to cancer-causing agents such as tobacco, alcohol, and sunlight. In addition, there are other risk factors. These include smoking, drinking too much, and unsafe sex. Some of these risk factors are controllable, while others cannot be controlled.
Cancers begin in a single cell. Cancer cells grow out of control, ignoring signals that tell them to stop growing or die. These signals are generated by the immune system. Cancer cells are able to ignore these signals because they contain a mechanism that allows them to repair mistakes. They also use enzymes to break down normal cells. Once they break down a normal cell, they may start to grow into a new tumor. These new tumors are called cancer metastases. They can spread to other parts of the body, such as the brain or liver.
Some cancers start in lymphoid tissues, bone marrow, or other organs. Leukemia, a type of cancer, starts in the bone marrow. It is usually caused by a mutation. It is also caused by the initial infection of a virus. Cancers also develop in bone marrow and blood vessels, as well as in muscles and tissues that line the internal organs.
Cancers are often difficult to treat because they can spread to nearby tissues. However, surgery can sometimes help. In some cases, chemotherapy may be needed. Cancers can be slow-growing or fast-growing. Some cancers can be diagnosed during a medical test. A biopsy is a procedure in which a small amount of tissue is removed. These tests may be done based on gender, age, or other risk factors. If the results are inconclusive, additional tests may be needed.
Cancer is classified into different types according to the type of cancer cells that form it. Some cancers are cancers of the epithelial cells that line the body’s cavities. Other cancers are cancers of the nerve cells. Some cancers are cancers of the lungs. Other cancers are cancers of the testes or ovaries. Cancers may also be mixed types. Some cancers are treated with surgery, while others are best treated with chemotherapy. Cancers may also affect the brain, causing stroke-like symptoms. These symptoms include weakness on one side of the body and headaches.
Cancer is also a big picture planner. When it comes to planning for treatment, it is important to understand the types of cancer and where they originate. This will allow you to plan ahead and determine whether your treatment plan is best suited for your needs.
