cancer

    Cards (5)

    • Mitosis is the process by which most cells divide, and it is important for growth and repair.
    • The cell cycle is controlled by two types of genes: oncogenes and tumor suppressor genes.
    • A mutation in one of these genes can result in uncontrolled mitosis.
    • Benign tumors can grow large but do not destroy surrounding tissue, while malignant tumors destroy surrounding tissue and can spread to other sites.
    • Treatments for cancer include surgery to remove cells, chemotherapy to disrupt the cell cycle, radiotherapy to damage DNA, and drugs that inhibit metaphase.
