In today’s time, cancer has become the biggest deadly disease. But the good thing is that if it is detected in the early stages, then its treatment can be easy and effective, yet only about 29 percent of the people in India get tested on time, that is, in most of the cases the disease is detected when it has progressed. Experts say that with regular screening, cancer can be eradicated and lives can be saved. So let us know why cancer screening is important and which tests should be done when.

In which only 15 percent of breast cancer cases are detected on time. Cervix cancer is diagnosed early in only about 33 percent cases. There itself
