NEET BIOLOGY

Detailed explanation-1: -Cancer is basically a disease of uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators.

Detailed explanation-2: -Cancer is a disease caused when cells divide uncontrollably and spread into surrounding tissues. Cancer is caused by changes to DNA. Most cancer-causing DNA changes occur in sections of DNA called genes.

Detailed explanation-3: -Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.

Detailed explanation-4: -Definition. 00:00. … Cancer is a disease in which some of the body’s cells grow uncontrollably. There are many different types of cancer, and each begins when a single cell acquires a genomic change (or mutation) that allows the cell to divide and multiply unchecked.

Detailed explanation-5: -Mitosis occurs infinitely. The cells never die in cancer, as cancer cells can utilize telomerase to add many telomeric sections to the ends of DNA during DNA replication, allowing the cells to live much longer than other somatic cells. [3] With this mechanism, cancer cells that usually die simply continue to divide.
