¿Qué es el cáncer?

Cancer is a complex disease with over 200 types, all starting from a single cell. It involves the transformation of healthy cells into cancerous ones through DNA damage, influenced by habits and genetics. The body's protective mechanisms, like apoptosis, can fail, leading to uncontrolled cell division and tumor formation. Tumors can metastasize, spreading cancer cells to other body parts, making early detection and treatment crucial.

What is the initial step in the transformation of a healthy cell into a cancerous one?

• Accumulation of DNA injuries

• Cell division

• Formation of a tumor

• Metastasis

Which process allows cells to self-destruct when damage is excessive?

• Apoptosis

• Metastasis

• DNA replication

• Cell division

What happens when the genes controlling protective mechanisms are damaged?

• Cells become dormant

• Cells divide uncontrollably

• Cells repair themselves

• Cells stop dividing

What is the term for cancer cells spreading to other parts of the body?

• Tumorigenesis

• Metastasis

• Carcinogenesis

• Apoptosis

Why is early detection crucial in cancer treatment?

• It eliminates genetic risk

• It stops cell division

• It prevents DNA damage

• It makes treatment more effective
