Cancer is defined as a group of various malignant diseases that disrupt the body’s normal functioning. With the rapid propagation of anaplastic cells, these diseases cripple the body’s immune defenses and destroy healthy cells and tissues. There are types of cancer that are quite common and can easily be diagnosed while there are others that can be considered as silent killers.
As of the present, the American Cancer Society refers to lung, prostate, and breast malignancies as the most common types of cancer in the world. These malignancies affect around 200,000 people every year in the United States alone.
Females are the most common victims of breast cancer. More than 20% of breast cancer patients die every year from the disease, others succumb to infection brought about by the side effects of chemotherapy treatment. Women in their peri-menopausal years are more prone to having this type of cancer than young adults. Yet some of the main factors that can predispose a young woman to breast cancer include cigarette smoking, excessive alcohol intake, constant exposure to radiation, pregnancy after the age of 35, and genetics.
Lung cancer on the other hand is caused mainly by long-term exposure to nicotine and harsh industrial-strength elements. Small cell lung cancer is caused by chain smoking for many years, while the non-small cell cancer is caused by prolonged exposure to asbestos, radon, silica, and other chemicals. A family history of lung cancer is also a potent predisposing factor to the disease.
As for prostate malignancies, they account for about 30,000 deaths every year. Until now, medical studies don’t have any concrete explanation as to why Black Americans are most susceptible to the disease. Caucasians on the other hand pose moderate risk to prostate cancer and Asians are the least susceptible.
The other cancer types that commonly affect people include colorectal, pancreatic, bone, renal cancer, and different types of leukemia. Up to this time, scientists and medical specialists still don’t have a concrete triggering factor as to why cancer occurs. The good news on the other hand is that chemo, radiation therapy, and other treatment methods for the diseases are done in order to ease the pain and promote the quality of life of cancer patients.
