Cancer – Causes, Treatments, and Prevention
Cancer is a disease in which abnormal or old cells continue to divide and grow, disrupting the normal cell growth cycle. Cancer develops when these cells begin to multiply beyond their normal limits and then form tumors. While the body is naturally made up of trillions of cells, each cell contains a unique set of genes that dictate how it will grow, divide, work, and eventually die. This orderly process is largely unaffected by age, but certain factors may make some cells abnormal.
As with any disease, the outlook for patients with cancer depends on the type and severity of the disease. While cancer is potentially fatal, early diagnosis and treatment can significantly increase the likelihood of survival. This is because cancer cells interfere with proper organ function, restricting the supply of oxygen and accumulating waste products. These effects may ultimately lead to death. Luckily, most cancer cases can be successfully treated. Smoking, exposure to ultraviolet radiation, and asbestos are all known carcinogens, which are the most common causes of cancer. Tobacco and other chemicals, which contain high levels of chloroform and other carcinogens, can also cause cancer. In fact, one in five cancer deaths are directly linked to smoking.
Many types of cancer are diagnosed by a doctor’s examination of a particular area of the body. Some are diagnosed during routine screening exams at certain ages, but many are discovered when a patient exhibits symptoms. When a person is diagnosed with cancer, the doctor will usually perform a physical exam to determine the cause of the symptoms and order various tests. Some of these tests are simple, while others may require invasive surgery or guided needles.
In some cases, the development of cancer is the result of multiple mutations in DNA. Some cancer cells have twice as many chromosomes as normal cells. Other cancer cells make energy differently than normal cells. These abnormalities are crucial because cancer cells cannot survive without these abnormal behaviors. This is why researchers have developed treatments that target these features of the cells. They are called ‘anti-cancer drugs’. A new study suggests that the new drugs available in the market can kill cancer cells.
Research has shown that 18% of deaths from cancer are caused by infectious diseases. The proportion varies between developing and developed countries. Infectious diseases are typically the cause of cancer in humans, but other infectious agents can cause the disease. These include bacteria and parasites, and may be responsible for the development of cancer. For this reason, it is essential to avoid exposure to these substances and ensure that you get plenty of rest, as physical activity is beneficial to your overall health.
Cancer is a devastating disease. While most cancers are curable, some are worse than others. Some can spread throughout the body, while others remain confined to one particular area. There are several types of cancer and each one has its own treatment options. Cancer is the number one cause of death worldwide. However, thanks to advances in detection and treatment, the death rate from cancer has decreased significantly. If you’re worried about cancer, talk to your doctor today.
