Cancer – Causes, Symptoms, and Treatment
Cancer can be caused by a number of factors. Generally, cancer begins in the cells of the body. These cells are formed when we need them and replace old cells that die. Sometimes, though, our bodies can’t produce enough cells to meet our needs and can start growing extra cells instead. These extra cells can grow and eventually form a tumor. Tumors are either benign or malignant and can invade nearby tissue and spread to other areas of the body.
Because cancer cells don’t die when they are supposed to, they can spread to other parts of the body. While benign tumors cannot spread, cancer cells can. Once they break off from the tumor site, they travel to other areas of the body and cause problems in other organs. This process is known as metastasis. It is the number two killer in the U.S., accounting for one in every six deaths. Cancer cells are caused by a series of changes in the genes. These changes are caused by lifestyle, genes from parents, and exposure to a number of agents that cause cancer.
Symptoms of cancer depend on where it has spread, but the main goal of treatment is to cure the disease. Depending on the type of cancer, treatment may include surgery, chemotherapy, radiation therapy, immunotherapy, and targeted therapies. Many people may not show any symptoms until they have already been diagnosed. But early detection can save lives. Cancer screening can also detect cancer at an earlier stage, allowing doctors to start treatment as soon as possible. The types of cancer treatments used in the treatment of this disease vary, but usually include chemotherapy, surgery, and immunotherapy.
Because it is impossible to prevent cancer in childhood, it is best to start early. Even a small bump on the head can lead to cancer. The same thing is true for adults. Some unhealthy habits can increase the risk of developing cancer. For instance, smoking, sun exposure, and obesity increase cancer risk in children. However, these habits may help a person’s body fight cancer later in life. Cancer is often the result of a long history of bad habits.
Many cancers are treatable, and the rates of death and diagnosis are decreasing yearly. Cancer screening tests, which include colonoscopy, mammography, and Pap tests, can detect cancer in otherwise healthy individuals. In addition, detecting cancer early allows physicians to select the most effective treatment for the patient. The right treatment can help them determine the most effective course of action and communicate their findings with other health care providers. So, if you feel you may be suffering from cancer, you should visit your doctor.
Leukemias and lymphomas are cancers that start in the bone marrow. They do not form solid tumors but instead crowd out healthy blood cells. When this happens, it becomes difficult for the body to get oxygen and nutrients to all the tissues and organs, control bleeding, and fight infections. Cancer can also spread to other parts of the body. Cancers have many different types, depending on where they start. If you are concerned about cancer, you can get involved in cancer research and become an advocate for the cause of it. Volunteering for cancer research and sharing your personal story can help the cause.
