The modern view of cancer describes the cells of a malignant tumoras genome stability clonal, each being genetically identical to the other cells in the tumor mutagenesis abnormal cells confined to a tissue within the patient angiogenesis genetically identical to the surrounding somatic cells from the same patient ered metabolism normal cells which have been converted to cancer cells by hormones drug resistance a complex mixture of cells, some malignant and some not Submit Request Answer Request Answer

Answer 1

1. B. Mutagenesis is a phenomenon of alternation of gene in an organism leading to mutation that is sudden change in DNA. Chronic inflammation causes DNA damage which is again a mutation which leads to cancer.

2. B. Cancer is an uncontrolled cell division of the cell. These cells are abnormal. They are called transformed cells. These cells are mutants whose gene are altered. So, the malignant tumors are tissues of these abnormal cells.

3. A. Age is the major risk factor in cancer because the mutation caused in the cells accumulates in the body with age. Also all the exposure to factors causing cancer increases with age. So, gradually gene alternation in genes accumulates in the body.
