Key Things To Know About Cancer
Cancer is a condition that is caused by abnormal cell growth. It is estimated that there are over 100 different forms of cancer. Prostate cancer, skin cancer, colon cancer and breast cancer are some of the most commonly-diagnosed form of cancers today. Approximately 7.6 million people in the world die yearly because of cancer.
What Causes Cancer?
Gene mutations, or changes, in DNA cause cancer. If there is a mutation, then the cells will stop their normal function. Doctors are not sure about what exactly causes this mutation. Some mutations are genetic. Other mutations can be caused by lifestyle factors, such as obesity, smoking, exposure to cancer-causing chemicals and radiation.
Many people do not have any symptoms when they are in the early stages of cancer. A person may only notice symptoms when the malignant tumor starts to grow. It is also important to note that the type of cancer a person has will affect the symptoms he or she experiences. However, there are some symptoms that are common with every form of cancer. Some of those symptoms include pain, unexplained bleeding, lumps and fatigue.
The signs of cancer are often overlooked. They may also be attributed to minor health conditions. That is why experts recommend seeing a physician if you notice any unusual or persistent symptoms.
Treatment Options For Cancer
It is estimated that 66 percent of people in America who have cancer are still alive five years after they are first diagnosed. The reason that more people are surviving cancer now than ever before is because there are a number of treatment options available today. The stage and type of cancer are two factors that determine the type of treatment that one is getting. A patient’s general health is also taken into consideration when doctors are trying to determine the best treatment.
The main goal of cancer treatment is to destroy or remove the cancerous cells in the body. Surgery, chemotherapy, immunotherapy, radiation and hormone therapy are some of the treatments available. There are also clinical trials being conducted in order to test future cancer treatments.
Anyone can develop cancer. However, there are things people can do that will help cut their risk. Maintaining a healthy body weight, drinking alcohol in moderation, exercising most days out of the week and not smoking can help cut your chance of having cancer.
