The so-called cancer is actually a genetic disease caused by genetic mutations.
Genes support the basic structure and function of life, storing all information about race, blood type, gestation, growth, and apoptosis.
Thus, a person's genes determine all their characteristics: height, weight, gender, and even lifespan are determined by genes.
Cancer is a mutation of genes for the worse, causing cells to proliferate infinitely, unrecognized and uncontrolled by human immune function, ultimately leading to a disease characterized by unlimited growth.
Simply put, it's cells dividing infinitely!
There's a saying that cancer is a mark of life's evolution. Normally, a human cell divides a limited number of times, about fifty times. If it divides till the end, about fifty times, then life ends, reaching the limit of its lifespan.
