Cancer is fast becoming a leading cause of fatalities all over the world. Moreover, it can happen to people of any age. So when it is hereditary or running in the family, regular screenings are a must. Regular screenings not only help detect the cancer if it is there early, but also helps the doctor in carrying out necessary intervention. Other than viral, bacterial and infections triggered cancers, other external factors like smoking, tobacco, radiations and industrial pathogens are responsible for causing cancers in people. Thus, checkups for cancer detection, identify the cancer in early stages and prevent it from spreading, through medication and therapies.
