Cancer – What You Need to Know
Cancer is a disease in which cells divide uncontrollably, causing tumors and damaging the body’s immune system. According to the World Health Organization, one out of every six people will develop the disease in their lifetime. Researchers are developing new treatments for cancer every day. It is caused by mutations in the DNA, which directs the division of cells. These changes can be inherited or acquired from environmental factors.
There are many types of cancer, including lung cancer, brain cancer, and breast cancer. Each type can spread throughout the body. When cancerous cells spread throughout the body, it is called metastatic cancer. Although there is no cure for cancer, improved detection techniques have led to a decrease in annual deaths from cancer. Furthermore, a greater awareness of the health risks of smoking has reduced the risk of developing cancer.
Most people develop a risk factor for cancer, which increases their chances of developing the disease. However, some people are genetically predisposed to cancer and don’t develop the disease. For instance, up to 36% of people have thyroid cancer that has not yet been diagnosed. Another example is that 80% of men will develop prostate cancer by age 80. If these individuals had not been diagnosed, they would have received unnecessary medical care.
Treatment protocols vary depending on the stage of the cancer and type. However, chemotherapy, radiation therapy, and surgery are the most common treatments for cancer. Many alternative therapies, such as homeopathic remedies, are also available. It is important to discuss the different options with your doctor before undertaking any alternative treatments. Depending on the type and stage of the cancer, the prognosis for a patient can range from good to very poor.
Some lifestyle choices are a major risk factor for developing cancer. People who smoke or expose themselves to sunlight may have higher risks of the disease. Certain dietary factors and lifestyle choices may also play a role. However, the exact causes of cancer are unknown. A heightened immune response can help control the growth of cancer cells and prevent the disease in some cases.
Many cancers are diagnosed through symptoms and screening. However, in some cases, a tissue biopsy is necessary to make a final diagnosis. During the biopsy, a sample of tissue from the suspected cancerous tissue is taken and examined by a pathologist. Some biopsy samples can be obtained through a simple needle, while others require surgery.
When a normal cell transforms into cancer, genetic changes occur in the DNA. These errors can result in the loss of the tumor suppressor gene or alter the apoptosis signaling pathway. These changes can also increase the cell’s reproduction rate. A combination of these mutations can lead to cancer in a cell.
Treatment for cancer is different for each patient. The most common form of treatment is surgical removal of the tumor, though chemotherapy and radiation therapy are also used. These treatments are often used in combination.
