Cancer is a group of diseases caused by uncontrolled growth of abnormal cells in the body. The body’s normal control mechanism breaks down and these cells start to multiply uncontrollably. These extra cells develop into tumors, but some cancers don’t form tumors at all. Although the overall rate of new cases has been decreasing over the past few decades, 39.5 percent of Americans will develop cancer in their lifetime. The exact causes of cancer vary widely, but there are several common causes and treatment methods.
Cells make duplicates of themselves and can either make perfect copies or bad copies. The problem is that cancer cells are bad copies. Some substances and conditions that can cause cancer can cause these processes to go wrong. For instance, alcohol raises the level of oestrogen in the body, which is known to increase the risk of breast cancer. Alcohol also causes cells to divide improperly and are associated with an increased risk of developing breast cancer.
Cancer is often first discovered when a person has an unusual symptom. A doctor will typically ask the patient about their medical history and order tests to determine the cause of their symptoms. However, some people with cancer have no symptoms at all and their cancer can be discovered during a medical test for another ailment. Additionally, screening tests can identify cancer in otherwise healthy individuals. These tests include mammography, Pap tests, and colonoscopy.
After a tumor has formed, cancer cells can spread to distant parts of the body. This process is called metastasis. Cancer cells can spread to other parts of the body, including the lymph nodes, which are small bean-shaped organs located in clusters throughout the body. Cancer cells can also spread to other parts of the body, including the bones, lungs, and brain. In some cases, cancer spreads to distant locations in the blood and lymphatic system, which is why cancer is so dangerous.
Understanding why cancer happens is important for patients and their loved ones. It can help patients understand more about cancer treatment options and how to cope with the condition. Cancer is a scary and frightening disease, but it is not an insurmountable battle. Learn more about cancer from a legitimate oncologist. If you want to find out more about the causes of cancer, read the book ‘Cure: Cure – Why Cancer Happens’.
Cancer in the bone marrow is not always deadly, but it’s worth noting that some cancers have few symptoms until they are advanced. This makes it extremely important to seek medical attention if you experience any of these symptoms. If you feel pain, bowel problems, or have any unexplained bleeding, see a doctor right away. Cancer is one of the most common forms of death, and there are many early warning signs that can be indicative of the disease.
Inflammatory cells cause tumors to grow. Cancer cells cause inflammation, which can lead to a host of other illnesses. Various treatments for cancer aim to boost the immune system’s ability to fight cancer. These include vaccines that train the immune system to fight viruses, and immunotherapy. In immunotherapy, patients can be injected with treatments that teach specific T cells to multiply and attack cancer cells. Once cancer cells are eliminated, these T cells calm down and remain in the body as memory T cells. These cells can continue to patrol the body, but now they can remember where they have seen the cancer cells and are ready to act accordingly.
