Cancer can be the ultimate result of:

All of these answers are correct

Somatic mutations

UV radiation and carcinogen exposure

Repeated cellular damage

DNA-repair mechanism failur

Solution

Yes given all options or conditions can cause cancer and it affects all over human body.

Somatic Mutation is type of mutation occurs in the somatic tissue of human body. It can happen at any part of the body except germ cells that is sperm and ovary. Thus it will not inherit genetically. Therefore somatic mutations can cause tumors ultimatly.

UV radiation is highly and uppermost cause for the cancer which brings about damage for DNA the genetic material of cell.Carcinogens are the type of chemicals which causes cancer for ex.aflotoxins - a fungal toxin produced by Aspergillus.

Repeated cellular damage can be caused by a stimulus which disrupts the normal homeostasis (it is cellular death caused normally in human body, in which it kills or eradicates the abnormal cells, dead cells and infected cells) of affected cells.The other causes for cell damage includes physical, chemical, malnutrition and other imunological factors.Cell damage can be reversible or irreversible.

DNA repair occurs when there is damage in the cell or due to physical damages and if there is abnormal cell growth. If there is no repair in the DNA or failure in repairing it, that causes growth of tumor which ultimatly causes cancer. Failure also causes in the immediate growth of abrupt cells fastly than normal cells, so it is fastest way of causing cancer.
