Detailed explanation-1: -The survival rate is often stated as a five-year survival rate, which is the percentage of people in a study or treatment group who are alive five years after their diagnosis or the start of treatment. Also called overall survival rate.

Detailed explanation-2: -As of January 2022, it is estimated that there are 18.1 million cancer survivors in the United States. This represents approximately 5.4% of the population. The number of cancer survivors is projected to increase by 24.4%, to 22.5 million, by 2032.

Detailed explanation-3: -The doctor describes her chance for survival as 50-50 and stresses that approximately 50% of the affected patients die in spite of round-the-clock treatment; with no treatment, death is virtually certain.

Detailed explanation-4: -Here’s the takeaway: the mortality rate is the number of people who die every year of a given cause in a specific number of people (often 100, 000). The survival rate is how many people are still alive at a specific time after diagnosis.

Detailed explanation-5: -Overall, the rate dropped from an average of 215.1 annual cancer deaths per 100, 000 Americans in 1991 to 143.8 in 2020. Five-year survival rates have also been increasing for an even longer period of time. The overall cancer survival rate was 49 percent in the mid-1970s. It currently sits at 68 percent.
