Cancer is a type of disease in which there is an uncontrolled growth of abnormal cells. This rapid growth results in formation of tissue lumps, called tumor. Tumors are oftentimes benign and not malignant. However, if it starts to grow in size, invades surrounding tissues and other body parts, and affects their function, it becomes a malignant tumor or cancer.
Causes and Risk Factors of Cancer
Cancer is caused by a lot of things. Genetics, for one, play a very big role. If breast and prostate cancer are prevalent in your family, then the likelihood of you having this type of cancer is also increased. Lifestyle and diet are also important factors. If you are smoking or drinking excessive alcohol with no exercise and no proper diet, then you are more prone to the development of lung and liver cancer. Other factors causing cancer include environmental factors such as constant exposure to the harmful rays of the sun and radiation exposure, an example of which is skin cancer. These are just some of the most common types of cancers, although there are over a hundred types.
